Description

Technical Field

[0001] The present application belongs to the technical field of cutting equipment, and specifically relates to a cutting machine. Background Art

[0002] As a common material processing equipment, the material cutting machine has been widely used in many fields mainly in the manufacturing industry. The material cutting machine usually includes a frame, a crossbeam, a cutting and cutting device and a material transfer structure. The frame is provided with a material processing table, the crossbeam can be installed on the frame in a longitudinally movable manner, the crossbeam spans across the two ends of the material processing table in a transverse direction, the cutting and cutting device can be installed on the crossbeam in a transversely movable manner, the frame is provided with a track extending in the longitudinal direction on one side of the material processing table in the transverse direction, the track is located below the crossbeam, and the material transfer structure can move along the track to transfer the material from the outside to the material processing table.

[0003] Since the material will be subjected to a lot of impact and vibration when cutting, it is easy to cause the material to deviate, thus affecting the cutting accuracy. In order to solve this technical problem, the cutting machine in the traditional technology is provided with a clamping device, including a pressure roller and a cylinder located on both sides of the material processing table to drive the pressure roller to move up and down. The cylinder is installed on the crossbeam, and the pressure roller moves up and down under the action of the cylinder, thereby realizing the pressing or separation of the material, so as to realize the compression and relaxation of the material, and ensure that the material can be stably placed on the material processing table during the cutting operation. The material transfer structure needs to move along the track and transfer the material. In order to avoid the interference between the material transfer structure and the cylinder during the movement, some cutting machines in the prior art set the cylinder located on the side close to the material transfer structure on the side of the material transfer structure away from the material processing table. When the material rotation structure needs to move along the track, the cylinder will lift the pressure roller to a height higher than the material transfer structure to provide a passage space for the material transfer structure. However, such an arrangement will result in a long non-contact portion between the pressing roller and the material when the pressing roller contacts the material, affecting the pressing degree of the pressing roller on the material. There is still a possibility that the material may be displaced during the cutting process, thereby affecting the cutting accuracy of the material. Utility Model Content

[0004] The present application provides a material cutting machine to solve the technical problem that in a traditional material cutting machine, the pressing degree of the pressing roller is affected by the presence of a long non-contact portion between the pressing roller and the material.

[0005] The technical solution adopted in this application is:

[0007] The cutting machine described in this application also includes the following additional technical features:

[0008] The first mounting component and the cutting device are mounted on the same side of the crossbeam, and a projection of the first mounting component on a horizontal plane is located outside a projection of the material processing table on the horizontal plane.

[0009] The piston rod of the first cylinder is connected to the upper side of the pressure roller, and the piston rod of the second cylinder is connected to the lower side of the pressure roller. When the piston rod of the first cylinder extends downward, the piston rod of the second cylinder contracts downward to drive the pressure roller to move downward. When the piston rod of the first cylinder contracts upward, the piston rod of the second cylinder extends upward to drive the pressure roller to move upward.

[0010] The first mounting component comprises a straight tube extending in the longitudinal direction, one end of the straight tube being connected to the crossbeam, the straight tube being provided with a mounting plate extending downward, and the cylinder body of the first cylinder being mounted on the mounting plate.

[0011] The mounting plate is arranged on a side of the straight tube facing the material processing table and is bent toward the material processing table.

[0012] The straight tube is detachably connected to the crossbeam via threaded fasteners.

[0013] The two ends of the crossbeam are provided with support columns extending downward, the crossbeam is connected to the frame through the support columns through a driving module, and the crossbeam moves longitudinally under the drive of the driving module; the second mounting component includes a straight plate, which extends in the longitudinal direction, one end of the straight plate is connected to the support column, and the cylinder body of the second cylinder is installed on the straight plate.

[0014] The driving module includes a driving motor and a reducer connected to the output shaft of the driving motor, the output end of the reducer is connected to a gear, the driving motor is installed on the supporting column, a rack is installed on the frame, and the gear and the rack are meshed for transmission.

[0015] The two shaft ends of the pressure roller are rotatably connected to the first mounting component and the second mounting component through seat bearings respectively.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0017] 1. The cutting machine of the present application includes a clamping device. When the material moves along the track to the preset cutting position under the driving action of the material processing table, the pressing roller in the clamping device descends and presses the material under the action of the first cylinder and the second cylinder, thereby increasing the degree of contact between the material and the material processing table and reducing the probability of the material being displaced due to factors such as vibration and impact caused by the cutting device during cutting, thereby helping to improve the cutting accuracy of the material; in addition, the first cylinder and the second cylinder are respectively installed on the crossbeam through the first mounting component and the second mounting component, which improves the The installation stability allows the pressure roller to stably perform an upward and downward movement stroke under the action of the first cylinder and the second cylinder, thereby improving the efficiency of the clamping device in clamping and loosening the material; on the other hand, the first cylinder and the second cylinder are installed on the crossbeam, which fixes the relative position of the pressure roller and the crossbeam, thereby locking the relative position between the pressure roller and the cutting device, that is, when the cutting device moves to the preset position under the drive of the crossbeam to perform cutting processing on the material, the pressure roller can also move synchronously with the crossbeam, thereby pressing against the area of ​​the material close to the cutting processing, further improving the cutting stability of the material. Furthermore, the first mounting component and the cylinder body of the first cylinder of the present application are both higher than the material transfer structure in the vertical direction. When the material transfer structure needs to transfer materials, it is only necessary to lift the pressure roller to a position higher than the material transfer structure to meet the movement needs of the material transfer structure. The first cylinder and the first mounting component will not interfere with the passage of the material transfer structure. Therefore, the first cylinder and the first mounting component can be preferably installed at a position close to the material processing table, shortening the volume of the non-contact portion between the pressure roller and the material when the pressure roller presses the material, thereby improving the tightness of the pressure roller against the material, helping to maintain the stable relative position between the material and the material processing table, thereby improving the processing accuracy of the material.

[0018] 2. As a preferred embodiment of the present application, the first mounting component and the cutting device are mounted on the same side of the crossbeam, and the projection of the first mounting component on the horizontal plane is located outside the projection of the material processing table on the horizontal plane. With such a configuration, the first cylinder can also be located on the same side of the crossbeam as the cutting device, shortening the distance between the cutting device and the pressure roller. When the pressure roller is pressed against the material, the distance between the contact position between the pressure roller and the material and the cutting position between the cutting device and the material is shortened. Since the closer the material is to the contact position between the pressure roller and the material, the less likely it is to shake. This further improves the tightness between the material cutting position and the material processing table, thereby further improving the material cutting accuracy. In addition, the projection of the first mounting component on the horizontal plane is set to be located outside the projection of the material processing table on the horizontal plane, avoiding the first mounting component from interfering with the lateral movement of the cutting device on the crossbeam, so that the projection of the reciprocating movement path of the cutting device on the crossbeam on the horizontal plane can at least cover the width of the material processing table, thereby meeting the all-round processing requirements of the cutting device for the material.

[0019] 3. As a preferred embodiment of the present application, the piston rod of the first cylinder is connected to the upper side of the pressure roller, and the piston rod of the second cylinder is connected to the lower side of the pressure roller. When the piston rod of the first cylinder extends downward, the piston rod of the second cylinder contracts downward to drive the pressure roller to move downward. When the piston rod of the first cylinder contracts upward, the piston rod of the second cylinder extends upward to drive the pressure roller to move upward. In this way, when the pressure roller is lowered, the piston rod of the first cylinder extends and the piston rod of the second cylinder contracts. Since the support stability of the cylinder to the pressure roller is related to the extension of the piston rod, when the pressure roller is lowered to the position against the material, the extension of the piston rod of the first cylinder reaches the maximum, and the contact stability with the material is low. However, at this time, the extension of the piston rod of the second cylinder is low, which can provide relatively stable support for the pressure roller, so that the pressure roller can stably press against the material, and provide a guarantee for the stable locking of the relative position between the material and the material processing table.

[0020] 4. As a preferred embodiment of the present application, the support stability of the beam is improved by setting a support column. The driving module drives the longitudinal movement of the beam by driving the support column to move, thereby avoiding direct driving force on the beam, so that the beam maintains a high stability during the movement, reduces the probability of the beam shaking, and enables the beam to more stably carry the cutting device, the first cylinder and the second cylinder. In addition, the support column also serves the function of connecting and fixing the straight plate, eliminating the need to set up installation positions for installing the straight plate at other locations, thereby optimizing the structural setting of the cutting machine.

[0041] like Figures 1 to 5As shown, a material cutting machine includes a frame 1, a crossbeam 2, a cutting and cutting device 3 and a material transfer structure 4. The frame 1 is provided with a material processing table 11, the crossbeam 2 can be installed on the frame 1 in a longitudinally movable manner, and the crossbeam 2 spans across the two ends of the material processing table 11 in a transverse direction. The cutting and cutting device 3 can be installed on the crossbeam 2 in a transversely movably manner. The frame 1 is provided with a track 8 extending in the longitudinal direction on one side of the material processing table 11 in the transverse direction, and the track 8 is located below the crossbeam 2. The material transfer structure 4 can move along the track 8 to transfer the material 7 from the outside to the material processing table 11. The material cutting machine also includes a pressing device 5 for pressing the material 7 on the material processing table 11. The clamping device 5 includes a pressure roller 51, a first cylinder 52 and a second cylinder 53. The first cylinder 52 and the second cylinder 53 are respectively connected to the two axial ends of the pressure roller 51 so as to be able to drive the pressure roller 51 to move up and down together. The first cylinder 52 is located on the side of the material processing table 11 close to the track 8 and is installed on the beam 2 through a first mounting component 54. The second cylinder 53 is located on the side of the material processing table 11 away from the track 8 and is installed on the beam 2 through a second mounting component. The first mounting component 54 and the cylinder body of the first cylinder 52 are both higher than the material transfer structure 4 in the vertical direction.

[0042] The cutting machine of the present application includes a clamping device 5. When the material 7 moves along the track 8 to the preset cutting position under the driving action of the material processing table 11, the pressing roller 51 in the clamping device 5 descends and presses against the material 7 under the action of the first cylinder 52 and the second cylinder 53, thereby increasing the degree of contact between the material 7 and the material processing table 11, and reducing the probability of the material 7 being displaced due to the vibration and impact of the cutting device 3 during cutting, which helps to improve the cutting accuracy of the material 7; in addition, the first cylinder 52 and the second cylinder 53 are respectively installed on the crossbeam 2 through the first mounting component 54 and the second mounting component, which improves the first cylinder 52 and the second cylinder 53 on the one hand. The installation stability enables the pressure roller 51 to stably perform an upward and downward movement stroke under the action of the first cylinder 52 and the second cylinder 53, thereby improving the efficiency of the clamping device 5 in clamping and releasing the material 7; on the other hand, the first cylinder 52 and the second cylinder 53 are installed on the beam 2, so that the relative position of the pressure roller 51 and the beam 2 is fixed, thereby realizing the locking of the relative position between the pressure roller 51 and the cutting device 3, that is, when the cutting device 3 moves to the preset position under the driving action of the beam 2 to cut the material 7, the pressure roller 51 can also move synchronously with the beam 2, thereby pressing against the area of ​​the material 7 close to the cutting processing, further improving the cutting stability of the material 7. Furthermore, the cylinder bodies of the first mounting component 54 and the first cylinder 52 of the present application are both higher than the material transfer structure 4 in the vertical direction. When the material transfer structure 4 needs to transfer the material 7, it is only necessary to lift the pressure roller 51 to a position higher than the material transfer structure 4 to meet the movement needs of the material transfer structure 4. The first cylinder 52 and the first mounting component 54 will not interfere with the passage of the material transfer structure 4. Therefore, the first cylinder 52 and the first mounting component 54 can be preferably installed at a position close to the material processing table 11, shortening the volume of the non-contact portion between the pressure roller 51 and the material 7 when the pressure roller 51 presses the material 7, thereby improving the tightness of the contact between the pressure roller 51 and the material 7, and helping to maintain the stable relative position between the material 7 and the material processing table 11, thereby improving the processing accuracy of the material 7.

[0043] Figure 5 H1 indicates the height of the cutting device 3, H2 indicates the height of the first mounting component 54, and H3 indicates the height of the first cylinder 52. H2 is greater than H1, and H3 is greater than H1.

[0044] Preferably, the material transfer structure 4 includes a clamp 41, and the clamp 41 includes two oppositely positioned upper clamps 411 and lower clamps 412. The upper clamp 411 and the lower clamp 412 respectively abut against the upper surface and the lower surface of the material 7 and fix the material 7 by clamping.

[0045] As a preferred embodiment of the present application, Figure 1 , Figure 4 As shown, the first mounting component 54 and the cutting device 3 are mounted on the same side of the crossbeam 2, and the projection of the first mounting component 54 on the horizontal plane is located outside the projection of the material processing table 11 on the horizontal plane.

[0046] Such an arrangement allows the first cylinder 52 to be located on the same side of the crossbeam 2 as the cutting device 3, thereby shortening the distance between the cutting device 3 and the pressure roller 51. When the pressure roller 51 is pressed against the material 7, the distance between the contact position between the pressure roller 51 and the material 7 and the cutting position between the cutting device and the material 7 is shortened. Since the closer the material 7 is to the contact position between the pressure roller 51 and the material 7, the less likely it is to shake, the tightness between the cutting position of the material 7 and the material processing table 11 is further improved, thereby further improving the cutting accuracy of the material 7. In addition, the projection of the first mounting component 54 on the horizontal plane is set to be located outside the projection of the material processing table 11 on the horizontal plane, thereby avoiding interference of the first mounting component 54 with the lateral movement of the cutting device 3 on the crossbeam 2, so that the projection of the reciprocating movement path of the cutting device 3 on the crossbeam 2 on the horizontal plane can at least cover the width of the material processing table 11, thereby meeting the all-round processing requirements of the cutting device 3 for the material 7.

[0047] As a preferred embodiment of the present application, Figure 2 , Figure 3 As shown, the piston rod of the first cylinder 52 is connected to the upper side of the pressure roller 51, and the piston rod of the second cylinder 53 is connected to the lower side of the pressure roller 51. When the piston rod of the first cylinder 52 extends downward, the piston rod of the second cylinder 53 contracts downward to drive the pressure roller 51 to move downward. When the piston rod of the first cylinder 52 contracts upward, the piston rod of the second cylinder 53 extends upward to drive the pressure roller 51 to move upward.

[0048] Specifically, the first cylinder 52 includes a first cylinder body 521 and a first piston rod 522, and the second cylinder 53 includes a second cylinder body 531 and a second piston rod 532. The first piston rod 522 and the first cylinder body 521 are located on the upper side of the pressure roller 51, and the second cylinder body 531 and the second piston rod 532 are located on the lower side of the pressure roller 51. With such an arrangement, when the pressure roller 51 is lowered, the first piston rod 522 extends and the second piston rod 532 contracts. Since the support stability of the cylinder to the pressure roller 51 is related to the elongation of the piston rod, when the pressure roller 51 is lowered to the position abutting against the material 7, the elongation of the first piston rod 522 reaches the maximum, and the abutment stability with respect to the material 7 is relatively low. However, at this time, the elongation of the second piston rod 532 is relatively low, which can provide relatively stable support for the pressure roller 51, so that the pressure roller 51 can stably press against the material 7, thereby providing a guarantee for the stable locking of the relative position of the material 7 and the material processing table 11.

[0049] As a preferred embodiment of the present application, Figure 3 , Figure 4 As shown, the first mounting component 54 includes a straight tube 541, which extends in the longitudinal direction, one end of which is connected to the cross beam 2, and the straight tube 541 is provided with a mounting plate 542 extending downward, and the cylinder body of the first cylinder 52 is mounted on the mounting plate 542. By providing the straight tube 541 and the mounting plate 542, a stable mounting position is provided for the first cylinder 52, and the distance between the first cylinder 52 and the cross beam 2 can be adjusted by changing the length of the straight tube 541, thereby reducing the design and assembly restrictions on the first cylinder 52.

[0050] This embodiment does not limit the structural form of the mounting plate 542, and it can adopt any one of the following embodiments:

[0051] Embodiment 1: The mounting plate 542 is disposed on a side of the straight tube 541 facing the material processing table 11 , one end of the mounting plate 542 is connected to the straight tube 541 , and the other end extends downward in a vertical direction.

[0052] Embodiment 2: Figure 3 As shown, the mounting plate 542 is disposed on a side of the straight tube 541 facing the material processing table 11 and is bent toward the material processing table 11 .

[0053] As a preferred example under Embodiment 2, the top of the mounting plate 542 includes a bottom wall extending in a horizontal direction and a side wall extending in a vertical direction, and an oblique supporting portion is provided at the bending portion of the top of the mounting plate 542, and the two ends of the oblique supporting portion are respectively abutted against the bottom wall and the side wall of the mounting plate 542.

[0054] As a preferred embodiment of this embodiment, the straight tube 541 is detachably connected to the crossbeam 2 by a threaded fastener. In this way, the detachable connection of the straight tube 541 is realized. When the straight tube 541 or the first cylinder 52, the second cylinder 53, the pressure roller 51, etc. need to be replaced or repaired, the straight tube 541 can be disassembled and the components installed thereon can be repaired or replaced one by one, which reduces the maintenance difficulty of the staff.

[0055] This embodiment does not limit the connection method between the straight tube 541 and the cross beam 2. In another embodiment, the straight tube 541 and the cross beam 2 are connected by welding; in another embodiment, the straight tube 541 and the cross beam 2 are integrally formed.

[0056] As a preferred embodiment of the present application, Figure 1As shown, downwardly extending support columns 21 are provided at both ends of the beam 2, and the beam 2 is connected to the frame 1 through the support columns 21 via a driving module, and the beam 2 moves longitudinally under the drive of the driving module; the second mounting component includes a straight plate 55, which extends in the longitudinal direction, one end of the straight plate 55 is connected to the support column 21, and the cylinder body of the second cylinder 53 is installed on the straight plate 55. By providing the support column 21, the supporting stability of the beam 2 is improved. The driving module drives the beam 2 to move longitudinally by driving the support column 21 to move, thereby avoiding direct application of driving force to the beam 2, so that the beam 2 maintains a high stability during the movement, thereby reducing the probability of the beam 2 shaking, so that the beam 2 can more stably perform the function of supporting the cutting and opening device 3, the first cylinder 52 and the second cylinder 53; in addition, the support column 21 also serves the function of connecting and fixing the straight plate 55, eliminating the need to set up installation positions for installing the straight plate 55 at other positions, thereby optimizing the structural design of the opening machine.

[0057] As a preferred embodiment of this implementation, the driving module includes a driving motor and a reducer connected to the output shaft of the driving motor, the output end of the reducer is connected to a gear, the driving motor is installed on the support column 21, a rack is installed on the frame 1, and the gear and the rack are meshed for transmission.

[0058] By setting a reducer, the output shaft speed of the driving motor can be reduced, and the output torque of the driving motor can be increased, so as to enhance the driving effect of the driving motor on the gear; in addition, by respectively setting gears and racks at the output end of the reducer and the straight tube 541, the support column 21 is moved through the meshing transmission of the gear and the rack, thereby improving the travel stability of the support column 21, and after the support column 21 reaches the preset position, the reducer is stopped by controlling the driving motor, the gear will stop rotating immediately, and the gear and the rack will be stuck to stop the support column 21 from moving, thereby improving the real-time movement or stopping of the support column 21; in addition, the support column 21 and the straight tube 541 are connected by a guide rail slider mechanism including a slider and a guide rail, which locks the motion trajectory for the relative movement of the support column 21 and the straight tube 541, so that the support column 21 can only move along the extension direction of the guide rail, thereby improving the movement accuracy of the support column 21.

[0059] As a preferred embodiment of the present application, Figure 2 , Figure 3As shown, the two axial ends of the pressure roller 51 are rotatably connected to the first mounting component 54 and the second mounting component respectively through the seat bearing 6. By providing the seat bearing 6, on the one hand, the installation and positioning of the pressure roller 51 is realized, and the pressure roller 51 is locked between the first mounting component 54 and the second mounting component, which provides a guarantee for the stable contact of the pressure roller 51 against the material 7; on the other hand, the seat bearing 6 can also provide a certain range of rotation angles for the pressure roller 51. When the pressure roller 51 contacts the material 7, the seat bearing 6 controls the rotation of the pressure roller 51, thereby achieving a tighter contact with the material 7 and improving the stability of the relative position between the material 7 and the material processing table 11.
