Description

Technical Field

[0001] The present invention relates to a stamping device, and more particularly to a rapid stamping device for copper-aluminum composite plates. Background Art

[0002] Stamping forming refers to a processing and forming method in which an external force is applied to plates, strips, tubes, profiles, etc. by a press and a die, causing them to undergo plastic deformation or separation, thereby obtaining workpieces (stamped parts) with the desired shape and size.

[0003] For example, the patent with the authorized announcement number CN219851603U discloses a rapid stamping device for copper-aluminum composite plates, including a workbench, an upper die and a lower die. A chip removal port is opened at the top of the workbench. The chip removal port is communicated with the lower die, and the workbench is fixedly connected with the lower die. A collection box is placed at the bottom of the workbench, and the collection box is communicated with the chip removal port. An anti-blocking mechanism is arranged in the chip removal port. In this utility model, during use, after the copper-aluminum composite plate is stamped, the scrap will fall into the chip removal port through the lower die and then into the collection box through the chip removal port. The electric hydraulic cylinder can be started. The movement of the piston rod of the electric hydraulic cylinder can cause the anti-blocking plate to rotate in the inner wall of the chip removal port. At this time, the scrap in the chip removal port can be pushed up and down to avoid blockage of the chip removal port, so as to achieve the effect of facilitating the operation of the staff.

[0004] Although there are advantages in the above technology, the inventor found that there are still defects: the processing efficiency is relatively low, and when demolding, the operation is carried out below the upper die, and its safety cannot be guaranteed. In view of this, the present invention designs a rapid stamping device for copper-aluminum composite plates. Summary of the Invention

[0020] Preferably, a plurality of balance support legs are fixedly installed at the bottom of the device base.

[0021] In view of this, compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] (1). In the present application, the copper-aluminum composite plate is placed on the annular frame, that is, laid flat on the top surface of each lower die. When stamping, the first servo motor works to drive the first lead screw to rotate, and the lifting table slides downward along the Z-axis chute, so that the pipe-passing drives the upper distribution seat to move downward, and then the upper stamping die moves into the lower die to realize the stamping processing and forming of the copper-aluminum composite plate. The setting of multiple modules can ensure that the processing dimensions of the same batch are consistent and improve the processing efficiency.

[0023] (2) In this application, when the upper distribution seat moves downward, the touch block moves downward accordingly and contacts the locking cross plate. The locking cross plate restricts the movement of the touch block. The upper distribution seat continues to drive the upper stamping die downward. The first supporting block, the linear rod, and the second supporting block continue to move downward, and the compression spring is compressed until the first supporting block contacts the touch block. At this time, the upper stamping die is inserted into the lower die, and the depth of insertion into the lower die is a fixed value. By rotating the rotary wheel disc, the second lead screw can be rotated to make the locking cross plate move along the limiting slide rail, so as to adjust the height of the locking cross plate, and then change the depth of insertion of the upper stamping die into the lower die. In this way, copper-aluminum composite plates of different thicknesses can be processed, and the applicability is effectively enhanced.

[0024] (3) In this application, when the touch block is blocked by the locking cross plate and the indicating arrow is aligned with the card slot at this time, when the linear rod continues to move downward, under the transmission of the first rack, the second rack, and the linkage gear, the indicating arrow moves horizontally until it is inserted into the card slot. At this time, the touch block is locked on the locking cross plate and will not loosen or shift. Furthermore, the upper stamping die punches and stays in the lower die to ensure the quality of the processed product.

[0025] (4) In this application, after the processing is completed, the upper stamping die disengages from the lower die. The electric push rod works and pushes the lower die, so that the lower die slides outward along the guiding slide rod and the inner bottom wall of the contraction bin, and finally is removed through the entrance and exit and is located directly above the contact head, avoiding the upper stamping die from obstructing the demoulding action and improving safety. The second servo motor works, making the driving gear rotate and driving the third rack to move upward. Then the Z-axis ejector rod drives the contact head to move upward to remove the processed copper-aluminum composite plate from the lower die. Description of the Drawings

[0051] Specifically, the moving mechanism includes a guiding slide rod 103 and an electric push rod 104. The guiding slide rod 103 is fixedly installed in the contraction bin. The base of the lower die 5 is slidably sleeved on the guiding slide rod 103, and the base of the lower die 5 is in sliding contact with the inner bottom wall of the contraction bin. The electric push rod 104 is fixedly installed in the contraction bin, and the output end of the electric push rod 104 is fixedly connected to the lower die 5.

[0052] Specifically, the demolding mechanism includes a guiding slide bar 105, a Z-axis ejector rod 106, a contact head, a motor base, a second servo motor 107, and a driving gear 108. The guiding slide bar 105 is fixedly installed at the top of the device base 1, and the number of guiding slide bars 105 corresponds to that of the lower die 5. A Z-axis ejector rod 106 is slidably installed in the guiding slide bar 105, and the top end of the Z-axis ejector rod 106 is located outside the guiding slide bar 105 and fixedly connected to the contact head. A notch is formed on the side surface of the guiding slide bar 105. A motor base is fixedly installed on the side surface of the annular frame, and a second servo motor is fixedly installed on the motor base. The output end of the second servo motor is fixedly connected to the driving gear 108 rotatably installed on the motor base. A third rack that moves in the notch is fixedly connected to the side surface of the Z-axis ejector rod 106, and the driving gear 108 meshes with the third rack. A hole is formed at the bottom of the lower die 5.

[0053] Specifically, when the lower die 5 is located inside the shrinkage bin, that is, when the lower die 5 is directly below the upper stamping die 4, when the lower die 5 moves outside the shrinkage bin, that is, when the lower die 5 is directly above the contact head.

[0054] The specific implementation mode of this embodiment is as follows: Initially, each lower die 5 is respectively located inside the corresponding shrinkage bin. The copper-aluminum composite plate is placed on the annular frame, that is, laid flat on the top surface of each lower die 5. During stamping, the first servo motor 304 works, driving the first lead screw 301 to rotate. Then the lifting table 302 slides downward along the Z-axis chute, driving the pipe threading 303 to drive the upper distribution seat downward. Further, the upper stamping die 4 moves into the lower die 5 to realize the stamping and forming of the copper-aluminum composite plate. The setting of multiple modules can ensure that the processing dimensions of the same batch are consistent and improve the processing efficiency.

[0055] When the upper distribution seat moves downward, the touch block 308 moves downward accordingly and contacts the locking cross plate 205. The locking cross plate 205 restricts the movement of the touch block 308. The upper distribution seat continues to drive the upper stamping die 4 downward. The first support block 305, the straight rod 306, and the second support block 307 continue to move downward, compressing the compression spring 309 until the first support block 305 contacts the touch block 308. At this time, the upper stamping die 4 is inserted into the lower die 5, and the depth of insertion into the lower die 5 is a fixed value. By rotating the rotary wheel 203, the second lead screw 202 can be rotated to make the locking cross plate 205 move along the limit slide rail 204, adjusting the height of the locking cross plate 205, and further changing the depth of insertion of the upper stamping die 4 into the lower die 5, so as to process copper-aluminum composite plates of different thicknesses, effectively enhancing the applicability.

[0056] When the touch block 308 is blocked by the locking cross plate 205, at this time the indicating arrow 310 is aligned with the card slot. When the straight rod 306 continues to move downward, under the transmission of the first rack, the second rack and the linkage gear 312, the indicating arrow 310 undergoes a lateral shift until it is inserted into the card slot. At this time, the touch block 308 can be locked on the locking cross plate 205 without loosening or shifting, so that the upper stamping die 4 punches and stays in the lower die 5 to ensure the quality of the processed and formed product.

[0057] After the processing is completed, the upper stamping die 4 disengages from the lower die 5. The electric push rod 104 works and pushes the lower die 5, so that the lower die 5 slides outward along the guiding slide rod 103 and the inner bottom wall of the contraction bin, and finally is removed through the entrance and exit and is located directly above the contact head, avoiding the upper stamping die 4 from obstructing the demolding action and improving safety. The second servo motor 107 works, causing the driving gear 108 to rotate and drive the third rack to move upward. Then the Z-axis ejector rod 106 drives the contact head to move upward to remove the processed and formed copper-aluminum composite plate from the lower die 5.
