Description

A punch, an automatic processing system with the punch, and a plate processing method

technical field

The invention relates to mechanical processing equipment, in particular to a punch, an automatic processing system with the punch, and a plate processing method.

Background technique

The side walls of containers are usually designed with a corrugated structure for strength. As shown in Figures 1 and 1A, depending on the cargo to be transported, some containers 1 are provided with ventilators 5 at both ends of the side walls. A group of ventilation holes 9 and one or more ventilator mounting holes 8 are provided in the middle. In order to facilitate processing, such a large-sized side wall 3 is usually formed by connecting a plurality of unit plates with a corrugated structure. For example, as shown in FIG. A plurality of unit plates 20 without ventilation holes. Here, according to different requirements, the position of the hole area on the unit board will also be different. Specifically, the hole area of the unit plate 10a is close to the left side of the unit plate, and the hole area of the unit plate 10b is close to the right side thereof. In one example, the length L1 of the unit plate 10 is 2339.5 mm, and the width W1 is 1116 mm. As shown in Figures 3A and 3B, the unit plate 10 has four corrugations 14 of the same size; the distance D between the center of the hole area 16 and the side edge 12 of the unit plate is relatively large, for example, 278 mm, and the distance D between the center of the hole area 16 and the side edge 12 of the unit plate is relatively large, for example, 278 mm, and the distance D from the end edge 11 of the unit plate is large. The separation distance is small. The unit board 20 is similar in structure to the unit board 10 except that it does not have ventilation holes.

For unit boards without ventilation holes, an automatic processing system is usually used for processing, such as a production line PL1 shown in FIG. 4 . First, use the flatbed machine M1 to process the sheet into a flat sheet. Then, the slab is transported to the first shearing device M2 through the conveying device, where it is used to cut the end edge of the slab according to the length of the unit slab. Next, the sheared flat sheet is conveyed to a roller (rolling) device M3 and processed to form a corrugated sheet. Afterwards, the corrugated board is transferred to the second shearing device M4, which is used to cut the side of the board according to the predetermined width of the unit board; finally, it is transferred to the chamfering machine M5 to chamfer the board. At this time, the finished product of the cell plate without ventilation holes has been processed. Wherein, the plates can be automatically transported between each processing device by a transfer device (not output).

However, for cell panels with ventilation holes, fully automatic production is not yet possible. On a production line, cell panels are usually conveyed along their length. At the same time, due to the needs of plate transmission, processing equipment can only be arranged on the side of the production line transmission direction. That is to say, during processing, the side 12 of the unit plate needs to be close to the processing equipment. Most of the existing ordinary punching machines are cantilever structures, and the distance between the center of the punching head and the body of the punching machine is usually smaller than the distance between the center of the hole area on the unit plate and the side of the unit plate. Therefore, it is impossible to process ventilation holes on an automatic production line with a common punch. At present, manufacturers usually use the automatic production line shown in Figure 4 to produce unit boards without ventilation holes; then lift the unit boards without ventilation holes to a punching machine located outside the production line, and then process the ventilation holes. Outside the production line, the cell plate can be placed with its end edge close to the punch, so that the ventilation holes can then be machined with a normal punch.

Since full-automatic production cannot be realized, the production efficiency of the cell plate with ventilation holes is obviously low. One solution is to choose a large-tonnage deep-throat punch. The distance between the punch center of this punch and the punch body is relatively large, which can meet the needs of processing holes on the production line. However, this deep throat punch is bulky and expensive, which is not conducive to the layout of the entire production line.

Contents of the invention

A technical problem to be solved by the present invention is to provide a processing method for a plate, so as to be able to process holes on a large plate.

Another technical problem to be solved by the present invention is to provide a punching machine to realize the processing of holes designed on large plates on an automatic production line.

The method includes: setting a punch press; setting at least one set of dies between the upper and lower worktables of the punch press; transporting the sheet material along its length to the lower worktable, and positioning the sheet material; and manipulating the moving head to punch a hole in the sheet with the punch.

Wherein, the step of setting up the punching machine includes: setting up a frame, which includes a base located below, two uprights arranged on the base, and a crossbeam arranged above the two uprights; setting the interval between the two uprights to be greater than the The width of the plate; at least one moving head is set on the beam, so that the moving head can move in the vertical direction relative to the base, and the center of the moving head is separated from the closer one of the two columns by a distance greater than The distance from the center of the hole area on the board to the side of the board; the lower workbench is set on the base; and an upper workbench opposite to the lower workbench is fixed below each of the at least one moving head. The step of setting the mold includes: setting an upper mold under the upper workbench of the punch press, and setting a group of punches at a predetermined position under the upper mold; The die is provided with a matching hole corresponding to the punch for receiving the punch during stamping.

To achieve the above purpose, the present invention also proposes a punch press. The punch press comprises: a frame, including a base located below, two uprights arranged on the base with a predetermined distance from each other, and a crossbeam arranged above the two uprights; at least one moving head is arranged on the crossbeam, and can moving in a vertical direction relative to the base; the center of the moving head is spaced a predetermined distance from the closer one of the two uprights; the lower worktable is arranged on the base; and the upper worktable is arranged below the moving head , and correspond to the lower workbench. Wherein, at least one set of molds is arranged between the upper and lower workbenches of the punch press. Each set of molds includes: an upper mold set under the worktable of the punch press; a punch set at a predetermined position under the upper mold; and a lower mold set on the workbench under the punch press and having the The matching hole corresponding to the head to accommodate the punch when stamping.

The automatic processing system further comprises the punching press according to claim 6, the punching press is arranged on the downstream side of the second shearing device and faces the conveying direction of the automatic processing system.

The punch press of the invention has a simple structure and is easy to implement. Due to the use of the frame of the gantry structure, the punch press has high rigidity, and a large distance can be separated between the two columns. In this way, even if the distance between the hole area of the plate and the side of the plate is relatively large, the punching machine can be used for hole processing on an automatic processing system.

Detailed ways

As shown in FIG. 5 , the punch press M100 of the present invention includes a frame 110 with a gantry structure. The frame 110 includes a base 112 below, two uprights 114 on the base and a beam 116 above the two uprights, wherein the distance D1 between the two uprights is greater than the width of the plate to be processed. Below the beam 116 is provided at least one moving head 120 that can move vertically relative to the base 112 for providing the pressure required for stamping. The center of the moving head 120 is spaced from one of the closer columns 114 by a predetermined distance D2 which is set to be greater than the distance D from the center of the hole area on the plate 10 to the side of the plate. In this way, it is possible to process holes in the plate 10 using the punch press on the production line. A lower workbench 150 is fixed on the base 112 . An upper table 140 opposite to the lower table 150 is fixed below the moving head 120 . Preferably, the punch press M100 of the present invention is driven by hydraulic means. Compared with the way that ordinary punch presses use electric motors for mechanical drive, the use of hydraulic drive is conducive to making the structure of the punch press compact and reducing the cost of the punch press.

As previously mentioned, the position of the hole area 16 on the plate 10 will vary depending on the mounting position of the plate 10 on the side wall 3 . In general, the positions of the hole areas on the plates 10a and 10b are symmetrically arranged. Therefore, preferably, as shown in FIG. 5 , two moving heads 120 separated by a predetermined distance D3 are symmetrically arranged on the punch M100 , and each moving head can work independently of each other. The predetermined distance D3 is determined according to the position of the hole area on the plate. The two moving heads 120 are symmetrical about the plane 109 . A controller 130 is provided on one side of each column 114 to control the two moving heads 120 respectively. An upper worktable 140 is respectively fixed below each moving head 120 . For the case where two moving heads are provided, the lower worktable 150 can be set as an integral structure, or can be set as two separate parts as shown in FIG. 5 . The preferred embodiment of the present invention will be described below by taking a punch press provided with two moving heads 120 as an example.

As shown in Figures 6 and 7, between the upper and lower worktables of the punch press, a set of molds 200 are respectively provided corresponding to each moving head. Here, two sets of molds 200 are arranged symmetrically with respect to the surface 109 . Each set of molds 200 includes an upper mold 240 fixed below the upper table 140 , and a lower mold 250 fixed above the lower table 150 . A set of punches 210 is fixed at a predetermined position below the upper mold 240, so that the position and arrangement of the punches 210 correspond to the holes to be processed.

The size of the guide sleeve 281 and the guide post 282 is set so that the two will not be separated when the punch press works normally.

When needing punching on the workpiece such as plate 10, at first plate is placed on the predetermined position of lower die 250; The punch 210 punches holes in the plate 10 .

In order to realize the automatic positioning of the plate to be processed on the punching machine, preferably, a positioning hole 253 is provided at a predetermined position of the lower mold 250, and a positioning block 230 that can slide up and down along the positioning hole is provided in the positioning hole. Before the plate moves to a predetermined position on the punching machine, a cylinder (not shown) can be used to make the positioning block 230 rise and exceed the upper surface of the lower mold, as shown in Figure 6, so that in the direction along the production line (Fig. Y direction) to position the board. Here, at least one chip hole 152 is dimensioned such that a cylinder can push the positioning block 230 through the chip hole. After the punching is completed, the positioning block 230 moves down to not protrude from the upper surface of the lower die, so that the plate can pass through the punching machine and enter the next working unit. Preferably, the width of the positioning block 230 can be set smaller than the width W of the positioning hole 253, so that the positioning block 230 can be adjusted along the width direction of the positioning hole 253 according to the position of the hole area on the plate to be processed.

According to a preferred embodiment of the present invention, the lower mold 250 includes a lower mold frame 271 disposed on the lower worktable 150 , and a concave mold 261 disposed on a predetermined position of the lower mold frame 271 . Wherein, the guide post 282 is fixed on the lower mold frame 271 , and the workpiece to be processed will be placed on the die 261 .

FIG. 9 shows a transmission device 300 for a conveying plate 10, comprising a conveying wheel set 310 and a guide wheel set 320 arranged relative to the conveying wheel set. The transfer wheel set 310 and the guide wheel set 320 are respectively arranged on two sides of the plate 10, and can rotate around axes 316, 326 perpendicular to the plate conveying direction. Specifically, the transmission wheel set 310 is arranged on the shaft 330 and can rotate with the rotation of the shaft 330 ; the guide wheel set 320 is arranged on the shaft 340 and can rotate with the rotation of the shaft 340 . A sprocket 332 is disposed on the shaft 330 for driving the shaft 330 to rotate or stop. As shown in FIG. 9 , the plate 10 is located between the transfer wheel set 310 and the guide wheel set 320 . When the transmission device 300 is working, the transmission wheel set 310 rotates, thereby utilizing the friction force to move the plate 10 forward; when the transmission device 300 stops, the transmission wheel set 310 stops rotating, and uses the friction force to keep the plate 10 at the current position . Wherein, the guide wheel set 320 rotates or stops correspondingly with the transmission wheel set 310 . The transmission wheel set 310 and guide wheel set 320 are arranged symmetrically with respect to the plane 309 respectively; In this way, the conveying device 300 can be used to ensure the position of the board 10 in the direction perpendicular to the conveying direction of the production line (direction X in FIG. 9 ).

Preferably, the transfer wheel set 310 and the guide wheel set 320 respectively have a cross-sectional shape matching the corrugated shape of the plate 10 . According to a specific embodiment of the present invention, the transmission wheel set 310 includes a first transmission wheel 311 arranged in the middle of the shaft 330 and two second transmission wheels 312 respectively arranged on both sides of the shaft 330; A first guide wheel 321 in the middle of the shaft 340 and two second guide wheels 322 respectively arranged on both sides of the shaft 340 . Wherein, the first transmission wheel 311 and the first guide wheel 321 have respectively convex and concave cross-sectional shapes, so as to be attached to the lower and upper surfaces of the corrugated board 10 respectively, so as to realize alignment of the board 10 along the X direction. positioning. The second transfer wheel 312 has an approximately rectangular cross-sectional shape to support the board 10 and provide sufficient friction during transfer. The second guide wheel 322 has an approximately trapezoidal cross-sectional shape, so as to further limit the plate 10 along the X direction and prevent the plate from deflecting left and right.

On the upstream side of the punch press, at a predetermined distance from the edge E (see FIG. 7 ) of the lower table 150 of the punch press, one or more transfer devices 300 are provided. Preferably, two transfer devices 300 are provided. Set the position of the punch so that surface 109 and surface 309 coincide. At the same time, the height of the upper surface of the lower mold 250 of the punch press from the ground is set to match the height of the conveying device 300 , so that the plate 10 conveyed by the conveying device 300 can be placed on the lower mold 250 of the punch press.

Fig. 10, taking the production line PL2 as an example, shows the automatic processing system of the present invention. The production line PL2 is similar to the production line PL1 shown in FIG. 4 , except that the production line PL2 further includes a punch M100 disposed on the downstream side of the second shearing device M4. Among them, the punching machine M100 is set to face the conveying direction of the production line PL2. In this way, after the side edge of the plate is processed by the second shearing device M4, it is sent to the punch M100, so that the punch M100 is used to process holes on the predetermined position of the plate. Wherein, the second shearing device M4 may include two plate shears to simultaneously trim two sides of the plate. According to the actual situation, the chamfering machine M5 can be set on the downstream side of the punch M100, as shown in FIG. 10 ; it can also be set on the upstream side of the punch M100.

The method for processing holes on the plate will be described in detail below with reference to FIG. 11 . When the plate is transported by the transport device 300 to a predetermined position on the upstream side of the punch M100 (step S1 ), a sensor is triggered to send an arrival signal. According to the arrival signal, the transmission device 300 suspends its work, and at the same time, the cylinder located under the positioning block 230 of the punch press works to push up the positioning block (step S2). According to an embodiment of the present invention, the positioning blocks on the two sets of molds can act separately. At this time, the positioning block corresponding to the position of the hole area on the plate rises to ensure the distance between the processed hole and the edge of the plate; while the other positioning block does not rise. After the conveying device 300 stops, the plate 10 will continue to move forward due to inertia until it hits the positioning surface 238 of the positioning block 230 and stops. After the arrival signal is sent by the sensor, delay for a predetermined time (step S3 ), so that the plate can reach the predetermined position on the punching machine (that is, collide with the positioning block 230 ). Afterwards, the moving head 120 on the punch press M100 works to start punching holes on the plate (step S4). During the stamping process, the positioning block 230 moves down (step S5). From the time when the moving head 120 starts to work, delay for a predetermined time (step S6), so as to complete the whole stamping process. Afterwards, the conveying device 300 restarts (step S7 ) to convey the hole-processed plate forward to leave the punching machine M100 . In this way, the hole processing of the plate on the production line is realized. Since the punching machine M100 of the present invention is installed in the production line PL2, even if the size of the board is large, it can be processed smoothly. Cooperating with other processing units in the production line PL2, the fully automatic production of unit plates with holes can be realized.

It should be clear that with the production line PL2 of the invention it is also possible to produce plates 20 without holes. At this time, it is only necessary to set the punch M100 not to work so that the plate passes through the frame 110 of the punch.

It should be noted that although the present invention has been described through the above embodiments, the present invention can also have other various embodiments. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and modifications to the present invention, but these changes and modifications should belong to the appended claims of the present invention and their equivalents within the scope of protection.
