Description

  The present invention relates to a cutting machine, and more specifically, it is possible to cut a material of a thick and long metal plate so that the rotation drive and the movement drive of a rotating member are synchronized, so that vibration is cut off at the time of cutting. Related to the cutting machine.

  1 to 3 show a cutting machine according to the prior art.

  As shown in FIG. 1, a mechanical cutting machine using a large-diameter circular saw 2 according to the prior art has a structure in which a circular saw 2 cuts a material 1 having a circular or polygonal end surface while linearly moving up and down. It is. A large-diameter power transmission device 12 is installed on the upper frame 11, and the circular saw 2 is connected to the power transmission device 12.

  A driving motor 13 is installed at the lower part of the upper frame 11 to provide rotational torque. In order to guide the linear motion of the upper frame 11, linear motion guides 14 are provided on both sides of the upper frame 11, and hydraulic cylinders 15 are installed on both sides for the vertical motion of the upper frame 11.

  However, since the conventional cutting machine has the same cutting direction acting on the circular saw 2 and the transfer direction of the heavy power transmission device, a large hydraulic cylinder is required, and the size of the cutting machine increases. However, there are problems that the circular saw 2 cannot be smoothly linearly moved due to its weight, and the quality of the cut surface is deteriorated due to the vibration of the circular saw 2.

  Further, when the length of the end face of the material 1 is longer than the diameter of the circular saw 2 or the thickness of the material 1 is thicker than the radius of the circular saw 2, an increase in the diameter of the circular saw 2 and the size of the cutting equipment is required. It is done. However, it is known that the vibration of the circular saw 2 increases rapidly in proportion to the increase in the diameter of the saw.

  Furthermore, when a metal plate is used as the material, the end face has a minimum length of 1.5 m, so there is a limit to increasing the diameter of the circular saw 2. Therefore, it has been impossible to cut a thick and long metal plate using the prior art.

  As shown in FIG. 2, a cutting machine using a large-diameter circular saw 2 (see, for example, Patent Document 1) shows a structure in which a material 1 having a small end face is cut while being rotated by a power transmission device 21. Has been.

  The power transmission device 21 is coupled so as to be rotatable about a hinge shaft 23 supported through a hinge bracket 22 of the fixed frame. The outer portion of the case of the power transmission device 21 is connected by a drive motor (not shown) and a chain belt (not shown), and the rotational torque of the drive motor is transmitted through the chain belt connected to the driving pulley 24. It is transmitted to the reduction gear train 21 and transmitted to the circular saw 2.

  At this time, the power transmission device 21 is rotated by the hydraulic cylinder 25. Thereby, the circular saw 2 connected with the power transmission device 21 approaches the raw material 1 which is a material to be cut.

  Compared to the invention shown in FIG. 1, the invention shown in FIG. 2 is superior in durability, has a relatively high cutting speed, and can reduce the size of the apparatus. There is a problem that there is not enough means for controlling the vibration in the axial direction. Further, as in FIG. 1 of the conventional invention, it is impossible to cut a thick and long metal plate.

  As shown in FIG. 3, the material 1 having a circular or polygonal end face is clamped by a mechanical cutting machine using a large-diameter circular saw (see, for example, Patent Document 2), and then fixed to the loading unit 31. Thus, a structure in which a circular saw 2 is used for horizontal cutting is shown.

  Therefore, a drive motor 33 that generates power, a large-diameter power transmission device 34 that is installed on the lower frame 32 installed on the bottom surface of the building and decelerates the rotational speed of the drive motor 33, and a large-diameter power transmission device And a circular saw 2 for cutting the material 1 placed horizontally so as to coincide with the center of the output shaft while rotating at high speed.

  In the case of this prior art, it is possible to cut a small material having a circular or square end face at a high speed, but similarly to the prior art shown in FIGS. 1 and 2, it is not possible to cut a thick and long metal plate as a material. It was possible.

  On the other hand, as a conventional technique for cutting a thick and long metal plate material, a cutting method in which a cut surface is melted using a gas has been widely used. However, in the case of gas cutting, generation of cutting waste generated from molten steel flowing down from the cut surface of the metal plate material is inevitable.

  In addition, due to the characteristics of the melting method using a cutting nozzle, the speed is slow, and there are problems such as a cut surface defect in which the cut surface is not uniform and thermal deformation of the cut surface.

  Such problems are known to increase as the thickness of the metal plate increases. This is problematic in that the yield is reduced and additional secondary processing is required.

  FIG. 4 is a view showing a cutting machine that cuts the material 1 while the circular saw 2 moves along the transfer rail 41 arranged at the lower part of the material 1.

  Such a moving cutting device has an advantage that it can be easily installed and can cut a material 1 having a long length. On the other hand, the frame 43 is configured to support only the weight of the circular saw 2. Therefore, it is weak against vertical vibration and torsional vibration due to a large cutting reaction force generated from the cutting of the material 1, and has a disadvantage that it is impossible to accurately transport the circular saw 2. Thereby, it is used restrictively in the process of cutting concrete slabs and retaining walls.

FIG. 5 is a view showing a cutting machine according to the prior art, FIG. 6 is a view showing a rotating part according to various embodiments inside a housing of the cutting machine of FIG. 5, and FIG. FIG. 8 is a view showing a rotating part according to various embodiments inside the housing of the machine, and FIG. 8 is a drawing showing a rotating part according to various examples inside the housing of the cutting machine of FIG.
In order to solve the above problems, as shown in FIG. 5 to FIG. 8, on the upper surface of the material 1, the combination of the rotary cutting motion and the linear transfer motion of the circular saw 2 is used to form the bottom surface of the housing. A mechanical cutting machine for cutting the thick and long metal plate 1 placed on the lower frame 51 to be installed was presented.

  Further, a power transmission device 52 is installed on the transfer frame 55, and a drive motor 53 for rotating a circular saw is installed on the upper portion of the power transmission device 52, and rotational torque is applied to the input side of the power transmission device by a pulley system. The circular saw 2 is rotationally transmitted through a speed reduction gear having a speed conversion gear train composed of a combination of one or a plurality of gears.

  At this time, the power transmission device 52 is supported by the transfer frame 55 and connected to the drive motor 54 for transferring the circular saw. The drive motor 54 converts the rotational motion into the linear motion of the power transmission device by the screw member 56 having a circular end surface penetrating the inside of the transfer frame 55 above the material 1, and the power transmission device 52 cuts the material 1. Move horizontally in the direction.

  However, in order to horizontally transfer the power transmission device at high speed, the power transmission device and the screw member 56 must reduce the frictional force and minimize the drive loss. On the other hand, the circular saw 2 has a rotational drive characteristic in which the magnitude and direction of the cutting resistance are continuously changed by the saw blade tip to which a plurality of pieces are attached at a constant angle, and vibration is likely to occur. There is a problem that the contact area between the apparatus and the screw member 56 has to be maximized, and there is a problem that it is very difficult to synchronize the rotary drive and the linear transfer of the circular saw.

  FIG. 9 and FIG. 10 are diagrams showing another cutting machine according to the prior art, and show a cutting machine for cutting a thick and long metal plate material as the material 1.

  The cutting machine shown in FIGS. 9 and 10 includes a frame support device 61. The frame support device 61 includes a loading means 68 for moving the material 1 by the cutting width while supporting the weight of the material 1, and the material 1. A plurality of clamp means 64 for compressing downward, a clamp frame 63 provided with the clamp means 64, a circular saw 2 for cutting the material 1, a power transmission device 62 for transmitting power to the circular saw 2, and power A transfer frame 65 is provided so that the transmission device 62 is transferred, and a transfer support column 66 that is laterally connected to both ends of the transfer frame 65.

  The transfer frame 65 of such a cutter has a structure in which the transfer frame 65 is connected to the transfer support column 66 so as to be movable in the lateral direction without being fixed. Further, the transfer support column 66 has a structure connected by a clamp frame 63 and a support bed 67.

  At this time, as shown in FIG. 10, the transfer frame 65 has vertical and horizontal cutting reaction forces periodically generated by the rotation of the circular saw 2 linked to the power transmission device 62, and the transfer frame 65 or the circular saw. 2 and the power transmission device 62 receive a torsional moment due to the difference in the position of its own weight (distance between forces).

  Accordingly, when the transfer frame 65 is twisted, the difference in the operation position further increases. As a result, an offset (vibration) is generated in the circular saw 2 as shown in FIG.

  Further, since the amount of sag of the transfer frame 65 changes due to the movement of the circular saw 2 in the cutting direction, the connecting portion of the transfer frame 65 and the transfer support column 66 receives a periodic bending moment.

  In addition, the support structure has an advantage that when the cut width of the cut portion of the material 1 is large, the upward lifting of the clamp frame 63 due to the clamping reaction force and the vibration of the transfer frame 65 or the circular saw 2 do not interfere with each other.

  However, when the cutting width is small, the horizontal distance between the clamp frame 63 and the transfer frame 65 is shortened in proportion to the cutting width, so that the transfer support column 66 connected to the support bed 67 is lifted by the upward clamping reaction force. By rotating, the offset of the circular saw 2 further increases.

  Such an offset of the circular saw 2 not only lowers the cutting quality of the material 1 by cutting the inclined surface during the cutting, but also the magnitude of the cutting reaction force and the amount of rotational vibration of the circular saw 2. As a result, there may be a problem that the cutting operation is canceled.

Further, in describing the present invention, when it is determined that a specific description related to a related known configuration or function may obscure the gist of the present invention, a detailed description thereof will be omitted.

It is drawing which shows the structure of the force which generate | occur | produces in a direction change unit.

  As shown in FIGS. 12 to 14, the cutting machine of the present invention includes a frame support device 100 provided with a transfer frame 130, a cutting unit 110 configured to cut a material, and rotating and moving the cutting unit 110. A driving member 120 that provides a driving force, and the driving member 120 is installed so that the cutting unit 110 is rotated by the driving force of the driving member 120 or moved along the transfer frame 130. A power transmission device.

  Here, the cutting means 110 may include a cutting member having a saw blade formed on the edge so as to cut the material.

  As an example of the cutting member, a circular saw can be used as shown in the drawings. However, the present invention is not limited to this, and any member can be used as long as it can easily cut the material 1 while rotating.

  Further, the power transmission device is configured to move the cutting means 110 along the transfer frame 130 while rotating the cutting means 110 by one drive member 120, and to synchronize the rotational drive and the movement drive of the cutting means 110. including.

  Here, as an example, the transfer frame 130 is a square support bar as shown in the drawing, and has a structure in which a housing 140 of interlocking means described later is fastened to the transfer frame 130 and is slid. It is preferable to take. Specifically, the transfer frame 130 has a structure that is fastened through the housing 140. In this way, the vibration generated by the cutting means 110 can be minimized by fastening while maximizing the contact area between the transfer frame 130 and the housing 140. Further, although not shown in the drawings, the transfer frame 130 may have a bore formed therein along its length to reduce weight.

  In addition, the interlocking unit includes a housing 140 in which the driving member 120 and the cutting unit 110 are installed and moved along the transfer frame 130, a moving unit that receives the driving force from the driving member 120 and moves the housing 140, and A rotating unit that rotates the cutting means 110 in conjunction with the moving unit.

  Here, the drive member 120 and the cutting means 110 are installed in the housing 140. At this time, the driving member 120 is firmly fixed to a portion of the housing 140 having a stable installation condition, and the cutting means 110 can be rotatably mounted at a position where it does not interfere with rotation.

  Such a housing 140 is slidably installed on the transfer frame 130, but a guide rail 131 is mounted on either the transfer frame 130 or the housing 140 for the movement guides facing each other, A guide protrusion line 141 that is fastened to and slides on the guide rail 131 may be formed. With such a guide structure, the housing 140 can slide smoothly and easily along the transfer frame 130, and the lubricating oil is filled between the guide rail 131 and the guide protruding line 141, so that friction caused by the movement can be achieved. Can be minimized.

  In addition, the moving unit is configured to move the housing 140 when a driving force is provided from the driving member 120.

  Specifically, the moving unit includes a first rotating shaft 151 installed to rotate in the housing 140, a connecting unit that connects the driving shaft 121 of the driving member 120 and the first rotating shaft 151, and a first rotating shaft. 151 and a direction change connection unit 155 for connecting the transfer frame 130.

  The connection unit may include a connection belt B or a first connection shaft 152 that gear-connects two adjacent shafts. That is, the connecting belt B connects the pulley 121a of the drive shaft 121 and the pulley 151a of the first rotating shaft 151 as shown in FIGS. 13, 17 and 18, or shown in FIGS. As shown, the pulley 121a of the drive shaft 121 and the pulley 152a of the first connecting shaft 152 can be connected. At this time, the first connecting shaft 152 gear-connects the drive shaft 121 and the first rotating shaft 151. For this reason, as shown in FIGS. 13, 15, and 16, the first connection shaft 152 and the first rotation shaft 151 can be connected to a connection gear G that is gear-fastened to each other. At this time, the connection gear G that is gear-connected to the first connection shaft 152 is an idle gear. As an example, the connection gear G is preferably a helical gear type that can transmit a large amount of power and is smoother in rotation and low in noise as shown in the drawings.

  Further, the direction changing connection unit 155 serves to connect the first rotation shaft 151 and the transfer frame 130 so that the first rotation shaft 151 moves along the transfer frame 130. The direction change connecting unit 155 may include a pinion gear 164 attached to the first rotating shaft 151 and a rack gear 165 attached to the transfer frame 130 and fastened to the pinion gear 164. As a result, the rotational driving force is transmitted from the driving shaft 121 of the driving member 120 to the pinion gear 164 through the first rotating shaft 151. Accordingly, the housing 140 can move along the transfer frame 130 to which the rack gear 165 is mounted by the rotation of the pinion gear 164. In other words, this is a configuration in which the cutting means 110 attached to the housing 140 moves along the transfer frame 130. At this time, as an example, a pinion gear 164 and a rack gear 165 are used. Although not shown in the drawings, it is of course possible to use a helical gear type that can transmit a large amount of power and that is smoother in rotation and low in noise. Further, backlash removing means (not shown) can be installed to remove backlash caused by the meshing between the two gears. As such backlash removing means, a powder breaker and a tension gear can be used as an example.

  Further, the diameter of the pinion gear 164 and the number of gear teeth of the two gears can be determined by the following formula from the moving speed of the cutting means 110 (moving speed of the pinion gear 164) and the rotating speed of the first rotating shaft 151.

[Formula 1]
D = 2v / w

  Here, D is the effective diameter of the pinion gear 164, and v is the transfer speed. W is the rotational angular velocity of the first rotating shaft 151 and is determined by the rotational angular velocity wn of the driving member 120 and the ratio of the diameter D1 of the pulley 121a of the driving shaft 121 to the diameter D2 of the pulley 151a of the first rotating shaft 151. .

[Formula 2]
w = wn × D1 / D2

  At this time, the rotational torque T and the power H required in relation to the horizontal transfer of the power transmission device are as shown in the following formulas 3 and 4.

[Formula 3]
T = m × G × D / 2

[Formula 4]
H = T × w

  Here, m is a coefficient of friction between the pinion gear 164 and the rack gear 165, and G is the weight of the power transmission device.

  On the other hand, the rotating unit is configured to rotate the cutting means 110 in conjunction with the moving unit. That is, the rotating unit does not require a separate driving member 120, and has a configuration in which the cutting unit 110 is rotated by the driving member 120 that provides a moving driving force to the rotating unit.

  Specifically, the rotating unit may include a second rotating shaft 161 that is installed on the housing 140 so as to rotate and to which the cutting unit 110 is attached.

  Here, the second rotating shaft 161 is gear-fastened with the first rotating shaft 151 as shown in FIG. 15, or the second rotating shaft 161 is moved by the second connecting shaft 162 as shown in FIGS. 13 and 18. The rotary shaft 151 may be gear-coupled to the first rotary shaft 151 or may have a structure extending from the first rotary shaft 151 as shown in FIGS. 16 and 17. At this time, the second connecting shaft 162 gear-couples the first rotating shaft 151 and the second rotating shaft 161. For this reason, as shown in FIG. 13 and FIG. A connecting gear G that is gear-fastened to each other can be attached to the connecting shaft 162 and the second rotating shaft 161.

  That is, the transfer support column 210 is disposed at the lower portion of the transfer frame 225 so as to support the end of the transfer frame 225 upward, and can be fixedly coupled to the lower surface of the end of the transfer frame 225.

  Such a transfer support column 210 is formed by the cutting means 224 by the torsional moment of the transfer frame 225 generated by the cutting reaction force of the cutting means 224 and the bending moment of the transfer frame 225 generated by the load of the transfer frame 225 and the cutting means 224. Plays a role in blocking the vibration of the.

  Specifically, the transfer support column 210 may include a transfer support portion 211 and a reinforcement support portion 212 that are coupled to the support base 201.

  Here, the transfer support unit 211 is coupled to the lower surface of the end of the transfer frame 225, so that the torsional moment of the transfer frame 225 generated by the cutting reaction force of the cutting unit 224 and the transfer frame 225 and the cutting unit 224. The bending moment of the transfer frame 225 generated by the load is cut off. For reference, the lower protrusion line 225a formed in the lower part of the transfer frame 225 is inserted into the upper groove 211c formed in the transfer support surface 211a, which is the upper surface of the transfer support part 211. The fastening fixing force of the transfer frame 225 is increased and the centering is guided.

  In addition, the reinforcement support 212 has a structure applied to one side of the transfer support 211 that opposes the torsional moment like a surplus, so that the torsion of the transfer frame 225 generated by the cutting reaction force of the cutting means 224 is obtained. The moment is cut off. That is, the reinforcing support part 212 added to one side of the transfer support part 211 firmly supports and reinforces the support base 201 as the transfer frame 225 tries to rotate to one side of the transfer support part 211 due to the torsional moment. Thus, the torsional moment of the transfer frame 225 generated by the cutting reaction force of the cutting means 224 is cut off.

  Meanwhile, the present invention may further include a clamp support column 220 installed on the support base 201 and supporting the end of the clamp frame 223.

As a result, it is possible to prevent the cutting means 224 from vibrating due to the clamping reaction force.

  Furthermore, the clamp fixing portion 221 can take an arrangement structure in which the height of the clamp support surface 221a that is the upper surface is lower than the transfer support surface 211a that is the upper surface of the transfer support portion 211. Thereby, since the height of the transfer support part 211 is not lower than the clamp fixing part 221, the one side 222a of the reinforcement fixing part 222 coupled to the end side surface of the clamp frame 223 is supported by the transfer support part 211. The effect of preventing the vibration of the cutting means 224 can be enhanced.

  For reference, a side groove 222c formed on one side surface 222a of the reinforcing fixing part 222 has a structure in which a side protruding line 223a formed on a side part of the clamp frame 223 is inserted. The fastening and fixing force of the clamp frame 223 is increased and the centering is guided. Furthermore, the other side surface 222 b of the reinforcing fixing part 222 guides centering when the transfer frame 225 is installed on the transfer support part 211.

  Furthermore, the clamp support column 220 and the transfer support column 210 configured as described above can be integrally formed, and can have a structure in which the reinforcing fixing portion 222 and the transfer support portion 211 are arranged. In addition, as shown in the drawings, the support base 201, the clamp support column 220, and the transfer support column 210 can be integrally formed, thereby facilitating the processing of the frame support device.

That is, the torsional moment and the bending moment of the transfer frame 225 generated by the cutting reaction force of the cutting means 224 and the load of the transfer frame 225 and the cutting means 224, and the upward movement of the clamp frame 223 by the clamp reaction force of the clamp frame 223. The second internal groove 222d is formed so that the deformation of the clamp support column 220 or the transfer support column 210 due to lifting does not interfere with each other.

  The present invention as described above includes a transfer support column 210 coupled to the lower surface of the end portion of the transfer frame 225 and having a reinforcing support portion, and a clamp support column 220 coupled to the lower surface and side surfaces of the end portion of the clamp frame 223.

  By such friction reducing means, the material 1 can be smoothly moved in the process of centering and clamping before the material 1 is placed and cut. Furthermore, after a part of the material 1 is cut, a smooth movement is possible even in the process of moving the material 1 to cut the other part.

  In addition, the present invention may further include a discharge unit that is provided in the frame support device 300 and discharges the material 1.

  Here, the discharge means can be configured to discharge a plurality of cut portions 1a generated by cutting the material 1 at different speeds.

  Specifically, the discharge unit can include a taper roll 381 installed in the frame support device 300 and a roll motor 382 that rotates the taper roll 381.

  Here, the taper roll 381 can take a tapered shape such that a plurality of cut portions 1a are placed and discharged at different speeds.

  The tapered roll 381 configured in this manner has a different diameter when the material 1 is placed even when a plurality of materials 1 are placed. 1 is discharged at a higher speed, and the material 1 placed on the portion having a small diameter is discharged at a relatively low speed.

  Further, the taper roll 381 can be formed with a locking portion 381a protruding at an end portion having a relatively small diameter so as to prevent the cut portion 1a of the material 1 from being detached. That is, after the material 1 is placed on the taper roll 381, the locking portion 381 a protrudes to an end portion having a small diameter in the taper roll 381 so that the material 1 is not slid and detached from the end portion having the small diameter. It can be formed with a structure.

  For reference, according to the present invention, a transfer conveyor 390 can be installed on the front end side of the taper roll 381, on which the cut portion 1 a of the material 1 cut is placed and transferred.

  As a result, as described above, the present invention includes the cutting means configured to cut the material 1 in the width direction and to perform the longitudinal direction cutting and the lateral direction cutting. Cutting and transverse cutting can be implemented simultaneously.
