Description of the invention (1) The present invention is about a method and device for manufacturing screws, rivets or the like, one of which is Jin Yi The wire is sent to a movable cutting bush at a receiving position through a fixed cutting bush, and then the movable cutting bush is moved away from the receiving position by crossing the direction of the metal wire axis on the real k A blank material is released from the line. The invention includes a method and a device for manufacturing an elongated object, which has a protrusion at one end and a pointed shape at the other end, wherein a blank is placed in a through-type mold, followed by a tool against the head end Under pressure, the other end of the mold is held by a jack. The invention also relates to a method and a device for ejecting a long blank from a through-type die, in which one end of the blank has been formed by a tool, and a push rod or pin extends from the other end Push it. The invention further relates to a method of forming a blank in a holding mold with a 1% through hole into an elongated blank, which includes pressing a tool against one end of the blank to apply an axial pressure. The manufacturing of screws and other objects is known by the upsetting process, in which the blank is placed in a mold, and one end of the blank is formed with a punch or a tool. Before being placed in a similar mold, the blank can be cut from a metal strand, for example. The typical method is called the cutting method. The method is to move a line of material through a cutting bush and move it into a cutting tool. As long as the tool is traversed in the direction of the longitudinal axis of the line, a piece of blank material can be cut from the line. These cutting tools are often open 1Γ, so this method is also called open cutting method. -3-(Please read the note ^ " item first; | write this page) Binding · Order _ Line-This paper is widely used in the "National Standards (CNS) specifications (210X297 public; it) 81. 4 ·] 0,000 sheets (Η) 202400 Λ 6 II 6 V.

In addition to the material, the former position of the situation, there is another mechanism in addition to the liner, and the liner is cut off. This is because after the extra step is issued, a punch of the blank can be moved to a position outside the chess by the transport mechanism. With the addition of a punch, the blank can be moved into the mold to implement a top-row forging rough mold. At the end, by means of a bottom stop, for example, in the form of a push pin, the closing material is removed from the cut-off position and inserted into the transport mechanism required by the mold. The cutting tool itself may form part of the transport mechanism. Below, when the punch moves the blank into the mold, the mechanism must be removed from the mold, so the yield is limited. In addition to the complexity of the lotus delivery mechanism, this open technology has the disadvantage of poor embryo quality. Unless there is complicated support in the cutting process to accommodate the wire material in the tool, the uneven quality of the embryo material will It is difficult to control during the molding process. A closed cutting method, the cutting tool has a closed cutting, and the quality of the produced blank is better. This method requires a complicated lotus feeding mechanism and S-push shot pin in the traditional screw machine to remove the blank Launched from the set. Therefore, additional work steps are required, and thus the yield is reduced to provide an advantage, but the closed cut-off is * ^ Zhang Liang. The high quality material, the alignment of the embryo material and the mold reduces the abrasion, avoiding the step of feeding the embryo material into the mold, and the yield is also improved. The advantage of this advantage in the Ming Dynasty is that the blank material released from the wire material and the movable cutting bush enter together into a discharge position, the child can move the blank material part into the mold, and Material pressure.

Description of invention (2) In order to cool the flow in the interval between the mold and the movable cut-off cover Make it rough. In the device of the present invention, the movable cutting bush is fixed on a lotus feeding device, and after a section of blank material is released, it can be moved from the cutting position to a position opposite to the die and between the die and the punch . The punch is used to move the blank part into the mold and press the blank to make it thick enough for cold flow in the interval between the mold and the movable cut-off set. When there are at least two movable cut-off sets as described in item 12 of the patent application scope, the two bushes can be simultaneously configured in a cut-out or bearing position and a discharge position relative to the mold It is particularly improved because, on the one hand, when the wire is inserted into one of the cut-off bushes, the blank in the other bush is moving into the die for pre-forging. In a special embodiment defined in item 13 of the patent application scope, a number of movable cutting bushes are arranged on a rotary cutting table, and multiple positions can be set according to the number of bell pepper sets. Due to the rotation of the cutting bush, a blank is released at the cutting position, when the relevant bushing is shifted to the next position (please read the notes beforehand • Matters 4 · Write this page) Ministry of Economic Affairs Central Bureau of Standards B3: Work permits to cooperate with Du Yin ¾, the end of the end of the line is set to be sharp or the end of the end.

Description of the invention (4 Printed by the Ministry of Economic Affairs, Employee and Consumer Cooperatives must be added separately. This nail is placed in the middle of the mold. The contract is given to push the blanks to make the sales work. It is necessary to have an invention between the advance materials, the mold is not smaller than the past, the groove method is more than that, it is considered that the part of the invention uses a relative action on the blank material to enter the top after the tool flows into the tool Workers can be borrowed. Borrow the work system, one out. The transition area in the technique with a large insertion force provides a precision that can be reduced to a small level. It can be difficult to achieve in this way. The head is recessed at the die and the die to form the concave nail head and wedge of the screw. The diameter of the auxiliary tool is smaller than that of the push pin model, and it is smaller in the screw and forms a kind of force. The force applied to the nail and the nail head is regarded as a generator. The first one has a concave, middle. When the head is depressed, the nail is pointed. The finished pin is formed by forming the nail wire. The nail head is unfinished. The screw head is pushed out of the pin head. The shape is weak. The screw is weak. Yu Xiaozhi's push must be bent with the blank material or the deformed material and the nail shank material can be formed into a groove with the same point method as the previous point. The mold shoots the pin at the tip of the nail and breaks. The weak between the material and the nail becomes the tip and the blank, and the tool is good. After the penetration of the spikes in the shape of the transition zone, the penetration of the blank material is completed and used for the narrowest part. The & Γ convenient method is the same. And it can be abraded to reduce f to reinforce. In the past, a well-known method was used to provide a preformed head after the head was sunken, and to produce a stream of material in the billet, with additional material, so that when pressed against the billet, the pressure The excess material is the material from the head to the shank-6- The shank of the screw is pressed down, and the most circular transition zone flows and is shaped I.

Description of the invention (5) (please read the notes on the back #rewrite this page) to make up. This also means that the force of the tool against the head is smaller than what was originally needed to form the head, which is sufficient. The device of the present invention includes a jack, which has a recessed extension to form a mold. The pressure between the tool and the mold causes the material in the blank to flow, and the additional blank flows down into the recess of the jack. The invention relates to a method and a device for ejecting a long object from a mold. When manufacturing long objects such as screws, it is known that a blank is placed in a mold and one end of the material is formed with one or more tools. The mold is usually a through-channel type. During the forming process, the opposite ends of the mold are often blocked by a bottom or a push pin is used to form the bottom of the mold. After the blank material is processed, a shot rod or pin is moved into the mold from the bottom end, and the blank material is completely pushed out of the mold. The length of the sales pin needs to be substantially the same as the mold or the blank material. However, the required thrust is large, so there is a risk of bending or breaking the long pin, which often occurs in existing machines. So far, this problem is often tried to solve by increasing lubrication to reduce the required thrust. So there is the purpose of using phosphate to lubricate the blank -----------------------------. . . . It is time-consuming and expensive, and will cause environmental problems.

Description of the invention (b) The introduction of the embryo material in the present invention is based on A relatively short push rod or pin moves the blank a short distance, and then pushes the blank completely with a stick or pin that is substantially the same length as the mold. The push is divided into two steps. First, loosen the blank with a short push pin and push it slightly out of the mold. Because the push pin is short, there are no bends or folds, so the capacity is larger. Once the blank is loosened for this pin, it can be pushed out of the mold with less force, so that the long pin can be used without any risk of folding. As mentioned in item 6 of the patent application scope, a simple control facility can be used to launch the blank. The first push rod or pin moves the blank to a defined distance to approach a control unit to generate a response to the embryo. The signal of the material geometry. The device of the present invention includes a first shorter ejector rod or pin to move the material for a shorter distance, and a second ejector rod or pin to push the blank out of the mold, the second pin It is the same length as the mold. '" In the embodiment described in item 18 of the patent application range, the device also includes a control unit, when the first push rod or pin tends to the control unit a well-defined distance, the control unit reacts to the blank The geometric shape generates a signal. This control unit can implement the measurement control of the blank in a simple manner, because it can determine the choice and selection of the blank based on the signal size. In the special embodiment described in Item 19 of the patent application scope, the Duo Printing Co., Ltd. of the Central Standards Bureau of the Ministry of Economic Affairs of the People's Republic of China applies the control unit shoulder " groove scout, which is used to follow the geometry of the screw head groove (for example: The depth of the groove) to generate a signal.

In addition to the problem-solving, the shape is very different from the spontaneous questioning to the foot model. The die edge can be divided into two parts, and if it is not in place, it can be made into a concave material if it is pushed and pushed by the diameter of the diameter. Embryo The shape of the embryo is easily measured outside the groove of the embryo. , Pieces of material for one piece, one piece of material, and a small piece of material. The small embryo will contain the embryo of the mold, including the small amount of material, and the first embryo will describe the embryo. When the material is shaped, the nail is pulled onto it, and the lift is stopped after the engraving-the stopper has the embryo Η and the screw part, so that the amount is measured. Starting from the anti-push push type into the bottom of the work is one of the steps involved; in Quan Xianneng, the small hole bursts into the toilet and completes the bounds of the amount of use: free or with a kind of concave push and plant. The force is small, and the work department is the one to make it to the original multi-time karma method. The stamping die is given to the special one. The middle diameter borrows from the fate to make the way to the subject, when When the pressure-moulding tool is raised, it can be used to pass the shaft, and it can be applied to a piece of material that rolls on the protrusions.

Figure 1 shows an example of a screw machine, which can be applied to the present invention. The machine is mounted on a base plate 1, and generally contains three main parts, namely a tool table 2, a forming mechanism 3 and a crank mechanism 4, which are driven by a motor mounted on the base plate 1. The starting material for manufacturing screw blanks is a cold drawing line 6, which has been drawn when pulling. —. . · 'A lubricant film is applied to its surface. The wire is drawn out by two straightening rods 7 and 8 having wire grooves corresponding to the diameter of the wire through a straightening device 9.

The transmission between the motor 5 and the crank 4 is achieved by the pulley 19 and the belt 20. ________. 1. The ± pulleys 21 and 22 are connected to a motor (not shown), and the tool table 2 can be moved toward or away from the die table 17 as a whole. The tool table 2 is guided by a slide bar 23 under the table and a corresponding slide bar on the table (not visible in the figure), and is adjusted to a correct position. When the tool or die table needs to be replaced, the tool table can also be moved away from the die table 17. The various components or procedures on board are detailed later. Figures 2 and 3 show the cutting and pre-forging procedures. Figure 2 is a section of the component, and Figure 3 is a perspective. The line 6 advances through the fixed cutting bushing 14 into a movable cutting bushing 24 installed in the rotating cutting table 15, the cutting table 15 has multiple movable cutting bushes 24, 25.

Description of the invention (11), the blank 2 6 is subjected to pre-u P set or pre-formed in the mold 16 and movable The cavity between the bushings 25 is cut off. The punch also acts as a pre-forged thick pin while the movable cutting bushing serves as a pre-forged thick bushing. What is described here is the application of a so-called closed cut method. The fixed cutting bush and the movable cutting bush 24 have a hole corresponding to the wire diameter. In traditional scraping or screw machines, the open cutting method is commonly used, in which the fixed cutting bush has a hole, and the movable cutting bush is open, so the wire embryo is only supported in the direction of progress. The quality of the closed-cut blanks used here is better, and the quality of the finished blanks is also better. The two movable cutting bushes 24, 25 shown in the figure are arranged on the rotary cutting table 15 with one relative to the die 16 and the other with respect to the fixed cutting bush 14. However, it is advantageous to install several more cutting bushes in the turntable 15, and the rotation angle of each cutting is smaller. For example, when four movable bushes are used, the cut wire blank can be positioned relative to the punch or pre-forging pin and the die 16 after cutting the turntable 15 to rotate a second angle. The steps of the pre-forging process are clearly visible in Figure 4. As mentioned above, the die 16 mounted on the die table 17 and its associated bottom stop 28 move along the axis direction of the die. On the other hand, the movable cutting bush 25 cannot be moved in the axial direction. Figure 4A shows the situation just at the beginning of the pre-forging. The pre-forging pin 27 pushes the wire blank 26 out of the bush 25 into the die 16 so that the blank 26 reaches the bottom stop 28 immediately before the die 16 contacts the pre-forging bush 25 at the turning point. The hole of the pre-forged bush at the end of the bush 25 facing the die 16 is provided with an enlarged portion 29. There is also a corresponding -1 3 in the mold 19-This paper is used in the "Sleepy Home Tenon (CNS) A 4 specification (210X29 / mm) (please read the back and the precautions ## write to this page) -Line.

Description of the invention (12) The enlarged portion 30, these recesses facilitate the formation of the head on the wire blank 26. (Please read the back-end notes first # 壻 write this page) The shape of these recesses. The purpose is to make the free segment of the wire embryo 26 as small as possible than the wire diameter d. The pre-forging pin 27 is controlled so that after the die 16 starts to move away from the bush 25 again, the pre-forging can still be held. In this way, when the diameter of the preform is increased, the height of the pre-forging is increased. The volume of the preform material must be increased without the instability of the preform, and the forging-to-roughness ratio is not limited by the process. The so-called upsetting ratio is obtained by dividing the head end wire length by the wire diameter. Figure 4B shows the situation at the end of the pre-forging roughing program. The height of the preformed head is L and the diameter is D. In addition to the relatively large forging thickness, this method can also reduce the load on the pre-forging pins. Fig. 5 shows another embodiment, for example, a movable bottom block which can be pushed to the pin 3 1 relative to the mold 16 is used to replace the bottom block 28, so that the control of the program can be better. In order to make the procedure in Fig. 4 better, the movement of the pre-forging pin 27 relative to the die 16 must be controlled by JD M precision bending. Figure 6 is an illustrative example. _. The side of the group shows the key components mentioned above, the die 16 and the bottom stop 28 are moving away from the bush 25, so that the spare embryo can form a head 32, and the punch or pre-forging pin 27 is still in the direction of 16 Press away.

When the or pre-forged lining is further advanced in the example of Fig. 9, it is the second just completed. The embryo material is in the state of the period. Figure 10 shows the generation of a blank, and it moves from one to one, which is called the first pre-completion to a new position. There are five molds 16 on the table to move forward to a new one relative to a movable cut. The above procedure is to remove the blanks at other mold positions, and the mold table 17 that is still here is moved to the tool again. Repeat the process at the table at 2 o'clock, and place in each mold. This shows that the pre-forging procedure followed by pre-forming is forming.

Invention description (14) A groove was formed. Figure A shows the start of the program, and B shows the end of the situation, the blank 54 is already a grooved blank. Many types of blanks have so-called pointed ones, for example, a shape such as a truncated cone is formed at the end opposite to the head. Figure 11 illustrates how to create the tip while forming the screw head groove. Figure 11 is similar to Figure 10A, a bottom file 55 is provided with a truncated cone-shaped recess 56, The through aperture of the self-mode 50 extends. The head of the blank 49 has been formed in the previous preforming process, and after completion, the screw head has more than the required size. When the groove protrusion 53 hits the head of the blank 49, the extra material is pressed down through the shank of the blank, the material flows along its full length, and is extruded into the frustoconical recess 56 of the bottom stop 55 Ο In this way, various types of tips can be installed, which vary according to the shape of the recess 56. Especially worth mentioning is the tip of the half-ball sphere, which must be done in the past with the procedure of sub-i. The method used here is simple, and the material flows along the embryo handle to minimize the load of the tool 52, and the tolerance of the finished product is small. This method can also be used for the manufacture of non-tip screws. In this case, the recess 56 can be cylindrical, and the aperture of the die 50 is the same size. When the groove protrusion 53 makes a groove in the head of the blank, the bottom stop only slightly recedes from the mold. The material flowing down through the handle of the embryo is what happened in the transition zone between the head of the embryo and the handle. This section is quite interesting. This is because it is found that this flow is sufficient to reinforce the weaknesses in the traditional screw transition zone. A certain type of tip may be made in two steps.

It can be seen that when the embryo is pushed out in the past, it needs to be broken and the base is actually formed in the first position of the screw embryo. However, the shape of the only piece can be used flexibly in three positions Eli Shigong. The table 17 has five molds, so each mold can be used to push the embryo. The push is shown in Figure 12. The first step of this push is shown at the top of the figure. There is a embryo in the mold 58.

As shown in FIG. 12, since the short push shot 60 pushes the blank 57 out of the mold by a well-defined distance, this can be used to control the generated blank. Figure 14 illustrates this effect. Fig. 14 is similar to Fig. 12, except that a control cone 64 is arranged at a carefully planned distance from the mold 58 to form a groove scout 63. The scout 63 is connected to an electronic device by a connecting wire 65, and can handle the multiples issued by the groove scout 63. The bottom of the figure shows that the short push pin 60 has pushed the blank 57 out of the mold 58, and the blank is in contact with the control cone 64. If the groove protrusion 53 used to make the screw head groove is damaged, the groove formed may be too small , Then the blank 57 will apply pressure to the control cone 64. This situation was recorded by the trench reconnaissance device, and the signal was transmitted from the connection line 65 to a control element. Here, the geometry of the embryos produced can be controlled. Du Printing by Employee Consumer Cooperation of the Bureau of Standards of the Ministry of Economic Affairs. Since the embryo has been introduced from the mold, it is also possible to control the height or diameter of the head in addition to the groove. Furthermore, the distance between the die and the tool table can be detected, and the signal of the scout 6 3 can also be used to adjust the tool. The machine starts in a cold state because the machine -1 8 _ 81. 4. 10,000 sheets (H) (please read the back-end precautions # 冀 write this page) This paper is used in the "National Standard (CNS) T4 specifications (210X297;": ") Λ 6 Π 6 ^ 〇24 〇Ⅴ. In the process of invention (17), the machine parts are gradually heated, and the parts expand at the same time due to heat. This expansion can be optimized by adjusting the position between the tool and the die in the die table 17. This can be done. As explained earlier in Figure 1, the entire tool table 2 can be replaced. This replacement is implemented because the control signal of the scout 63 is returned, regardless of the thermal expansion of the machine. Guanyu, better uniformity of the product is available. The groove scout shown is only one of many control measures possible for the resulting blank. There are many possibilities for the placement of other geometric characteristics of the product, and the ways of them vary. For example, the laser is used for measurement, so the reconnaissance device does not need to be in contact with the produced object at all. For example, using the method shown in Figure 10 above to create a groove in the head of the blank, that is, the groove forming tool may inadvertently pull the blank out of the mold. This section can be prevented by the method shown in Figure 15. During this time, a blank 66 is placed in a mold 67 with a bottom stop 68. The embryo has a head 69 at one end, and a small holding flange 70 can be seen at the opposite end. The protrusion line is formed in an expansion gap behind the through hole of the mold. In the pre-forging roughing procedure described in Figure 4, the material is also pressed out of this expansion gap to form a green. The small protrusions on this embryo, as long as it can play the embryo, avoid being inadvertently The function of pulling out the mold is not necessary, and it does not need to be spread around. Because it is very small, when the rear embryo is pushed out by the push pin, it can be deformed in time without hindering the ejection of the mold. Fig. 16 shows the formation of the reciprocating movement of the die base 17 and its associated bottom stop. As previously mentioned in Fig. 1, this axial movement is provided by a motor 5, and the power is transmitted via belts 19, 20 and a crank mechanism 4. Figure 16 shows this in detail-19-This Paper "Standard Chinese National Standards (CNS) (210X297mm) (please read the notes to the back ^ * 项 # 务 write this page) The Central Bureau of Accreditation only printed 5i 81. 4. ) 0,000¾ (H) Λ β Π 6 202400 V. Description of the invention (1β) The structure of a mechanism. (Please read the back first and pay attention to the item #price write this page) As mentioned, the belt 20 drives a crank 71 to rotate around the rotating shaft 72. A continuous guard 73, one end of which is mounted on the crank 71, and the other end is connected to a holder 74. The holder 74 is connected to the two wedges 77 and 78 via the two rods 75 and 76. When the crank 71 rotates, the connecting rod 73 is transformed into the reciprocating motion of the holder. The wedges 77 and 78 connected via the rods 75 and 76 are also the same Can go back and forth. There are many small sticks 8 1, 8 and 2 between the wedges 77 and 78 and the guide rails 79 and 80, and the friction due to the reciprocating motion is extremely small. Between the wedges 77 and 78, there is a bearing block 83 interposed, and the bearing block 83 can only perform the lateral lotus movement sandwiching the stroke of the wedge, because the stick groups 84 and 85 are arranged between the bearing block and the guide rails 86, 87, The friction of lotus movement is also very small. There are many sticks 88 between the block and the wedge 77, and sticks 89 between the block and the wedge 78. When the wedges 77 and 78 move to the left of the figure, the bearing block 83 moves downward because it can only move laterally. Similarly, when the wedges 77, 78 move to the right, the block 83 moves upward. Therefore, the bearing block 83 reciprocates in the lateral direction as the wedge lotus moves. The selection of the wedge angle in the figure aims to make the bearing block smaller than the wedge. The block 83 is connected to the die base 17 and its associated bottom stop via connecting members (not shown), respectively. The Ministry of Economic Affairs, Ministry of Economic Affairs, Bureau of Industry and Commerce, cooperated with Du Yin 5i, so that the die table 17 can perform a short reciprocating lotus movement, and at the same time, it can exert force when forming the embryo in the mold. Based on the selected wedge angle in the figure, the wedge and the crank mechanism can perform larger movements and require less force, so the size of the crank mechanism can be smaller than in the past. The sticks 81, 82, 84, 85, 88, 89 in Fig. 16 are intended to reduce the friction between the parts, and other shapes such as spherical ones are also necessary.

Description of the invention (1 is shown as a sliding guide. The sliding guides 90, 91 are used to reduce the friction between the wedge 77, 78 and the guide rails 79, 80, and the sliding guides 92, 93 are used to reduce the friction between the bearing block 83 and the guide rails 86, 87. Finally, the sliding guide 94 95 is used to reduce the friction between the bearing block 83 and the wedges 77, 78. It is important that the higher the productivity of this type of machine, the better, and the lower the speed of the mold at the beginning of actual forming, the better. By the above The use of the wedge mechanism can realize these expectations. A well-selected wedge angle can make the wedge block, that is, the die table have a smaller stroke. Furthermore, in this type of movement, the velocity of the die table close to its final position is much Not the same, it is explained in the eighteenth and nineteenth figures. Figure 18 is a schematic diagram of a crank mechanism. The crank rotates around a rotation axis C. At one end of the crank has a length a connected to the center of the rotation axis r The rotation of the crank causes the other end P of the connecting rod to reciprocate on the horizontal line. The distance from the center C of the shaft to the figure P is JI. It can be seen at the top of figure 19. When the crank rotates at a constant speed, the distance Λ is a function of time. If the length a is much larger than the distance r, the point P is a pure sinusoidal movement, as in the first (please read the back and forth notes # > r writes this page) Central Sample Bureau of the Ministry of Economic Affairs C3: The connection of the printed Qu poles of the industrial and consumer cooperatives.

Description of the invention (20) Here, Ρ ·· ώ is approaching one extreme at a lower speed and approaching the other extreme at a higher speed, which is more clearly visible. To obtain the lowest working rate at a given production rate, the die table is connected with blocks 83, so that the in-mold blanks are formed when the die table approaches one of the extremes at the lowest speed. As mentioned above, the die table 17 and its associated bottom stop become a common unit during the forming stage, move toward the tool, and then leave again. However, in the relative extreme position, the die table must be separated from the bottom stop, so that the die table can be turned to a new position. This section can be achieved by installing a stop device that prevents the die table from reaching its final position with the bottom stop. However, it will produce a lot of ridge sounds and the mold table will be greatly abraded, partly due to the mold table when it touches the stop device, and partly because of the bottom table when it comes back to the mold table. This problem can be solved by inserting a transition period. The die table reduces the speed before it hits the stop, and accelerates before it is hit by the bottom gears. Fig. 20 shows how to achieve this goal by means of a cam device 96. In FIG. 20A, the die table 17 is in contact with a tool such as 98 at an extreme position. As can be seen in the figure, a bottom stop 97 is in contact with the opposite end of the die table 17. The cam device 96 is provided with a labyrinth 100 and moves along the axis transverse to the stroke of the die table. The arrow in the drawing shows that the die table 17 contacts the tool 98 and then moves away in the direction of the arrow, and the cam device 96 moves upward. As can be seen in the figure, the cam 96 has a labyrinth of 100, and a stick 99 is mounted on the die table. Fig. 20B shows that the die table 17 together with the bottom stop 97 has been moved away from the tool 98 and it will encounter the cam device 96 which is following the ascent of the mine. In Figure C, stick 99 has touched labyrinth 100. The shape of the labyrinth 100 is matched with the speed of the cam device 96 -22-This paper size A is used in the BS Jiayu standard (CNS) T4 specification (210X207 male dragon) 81. 4. 10,000¾ (H) (please read the back-to-back note—item #stage hoops page) Installation · Line · Ministry of Economic Affairs, Bureau of Standards E3: Industrial and consumer cooperation Du Yin 5i 〇〇24〇〇Λ 6 II 6 Ministry of Economic Affairs Printed by the Central Authorities Bureau employee cooperative. V. Description of invention (21) The die table 17 was held at a constant speed just after contacting the roller 9 9 and the curved path 1000, and then live. As can be seen in the figure, the base stop 97 has succeeded in its actions and no longer contacts the die table. Figure 20, D shows the situation when in the extreme position, during which the die table 17 and the bottom stop 97 are both withdrawn from the tool. At this time, the die table 17 is separated from the bottom stop 97 and can be turned to a new position. Then the program proceeds in the opposite direction. The bottom stop 90 is moved toward the die table 17, and the die table 17 accelerates at the same time. This is because the cam 100 cooperates with the roller 99, and the cam device 96 moves downward at this time. Due to the shape of the labyrinth 100, when the die table 17 is hit by the bottom stop 97, it reaches all speeds at that time. Figures 21, 22 and 23 show the three different motions and speeds of the wedge 17 and bottom stop 97, respectively. The diagrams on the top show the movement of the lotus, which is illustrated by the distance A from the tool. The lotus movement of the bottom gear 97 is shown by a thin line, and the lotus movement of the die 17 is shown by a thick line. The speeds (V) shown below are thin lines for the bottom gear and thick lines for the die table. Figure 21 shows the situation without a transition period. The die 17 only hits a stop device on the way out of the tool, and then is hit by the bottom stop on the way to the tool. The lotus movement of the bottom block is represented by a pure sine curve here. As mentioned above, this is true only when the length of the connecting rod used is longer than the crank size. The correct curve is shown in Figure 19. The half-time model is in the indwelling position and can be rotated, while the bottom stop holds a harmonious lotus to its final position and then returns. In Fig. 22, a transition period is inserted between the working period in which the die table 17 and the bottom stop 97 move together and the retention period in which the wedge table is stationary. -23- (Please read back to note f and then this page) Binding · Threading · This paper is used for BB family tree pregnancy (CNS) T4 regulations (210X297;; :) 81. 4. 10,000¾ (H) Λ 6 II 6 c〇24〇〇 V. Description of the invention (22) (Please read the notes on the back then read this page) Figure 23 shows the transition period is very long, The case where the retention period is so short that it is zero. This situation has an advantage, the mold table 17 also performs harmonious lotus motion, so it may be subjected to the minimum force in the axial direction. Fig. 24 is a cross-sectional view showing a die 102 installed in a die table 101. The ring die 102 has a tape 103, which may be a dysprosium tape wound around a cylindrical core or a cylindrical insert. The core can be made of hard gold, and the mold 102 itself is not necessary. When the stopper 102 receives a huge compressive force in the axial direction, the winding belt 103 absorbs the outward force to bind the die 102. Figure 25 shows a partial section through the die table 101, where it can be seen more clearly why the die 102 is installed in the die table 101. The mold 102 here is shaped like a hammer, and is installed in a bushing 104. The inner mask of the sleeve has a taper corresponding to the mold. The bushing 104 is wound around the tape 103, and a suitable hole is formed in the die table 101. This structure has an advantage, because the mold 102 is tapered and can easily be pressed out of the bushing 104 and replaced. The new mold can be pressed into the tapered bushing 104 to ensure that it is properly secured. The advantage of using a hard metal mold as this bundle is that the mold and the bundle can have a small cross-section, which means that the mold on the mold table can be placed closer to the rotation axis of the mold table, with ribs on it The reduction of the moment of inertia. Figure 26 shows an example of a die set 101, with five die sets on the stage, all of which are printed and bound by the above-mentioned winding tape. For high productivity, the moment of inertia must be as small as possible. Partly because the mold is bound by the winding belt, the volume is not large; in addition, the mold can be arranged close to the wedge table rotating shaft 105 to achieve this purpose. The recess 106 is provided between the wedges, which can further reduce the moment of inertia. So the die table becomes lilac leaf shape, the material of the concave is dug away, the distance is -24- the size of this paper is not the same as China National Standard (CNS) T4 specification (210X297 male dragon) 81. 4. 丨 0,000 sheets (H) Λ 6 Π 6 _ V. Description of the invention (2 3) The rotating shaft 1 0 5 is the farthest, and has the greatest contribution to reducing the moment of inertia. In addition, the known machines often use heavy and long molds, and the same length as the blanks used here also has the advantage of reducing the moment of inertia. The moment of inertia is small, so it can be directly driven by a servo horse with high productivity. The above description is only for explaining how the machine of the present invention can be constructed, and its illustrations and details can be changed without departing from the spirit of the present invention.
