A slide groove 16 is provided on the upper surface of the workbench 1 near the first cross bar 14 and the second cross bar 2. The lower surfaces of the first cross bar 14 and the second cross bar 2 are respectively fixed with a first tooth plate 17 and a second tooth plate 22, and the first tooth plate 17 and the second tooth plate 22 are both slidably arranged in the slide groove 16. The two ends of the workbench 1 are respectively provided with a first gear 18 and a second gear 23 near the first tooth plate 17 and the second tooth plate 22. The first gear 18 is meshed on the first tooth plate 17, and the second gear 23 is meshed on the second tooth plate 22. The first gear 18 and the second gear 23 are respectively fixed at the center of the first gear 18 and the second gear 23. One end of the first rotating rod 19 and the second rotating rod 24 passes through the workbench 1, and a driving component is provided between the two.

[0024] The driving assembly includes a transmission shaft 3, which is rotatably set on the workbench 1 and close to the first rotating rod 19. The transmission shaft 3 is connected to the first rotating rod 19 through two meshing driving gears 31, and the transmission shaft 3 is connected to the second rotating rod 24 through a belt 32.

[0025] By adopting the above technical solution, the first rotating rod 19 and the second rotating rod 24 can rotate towards or away from each other at the same time through two meshing driving gears 31 and belts 32. The belt 32 can be made of a toothed material, thereby eliminating the hysteresis between the second rotating rod 24 and the transmission shaft 3.

[0026] A motor 33 is installed on the outer wall of the workbench 1 near the second rotating rod 24 , and an output end of the motor 33 is coaxially fixedly disposed on the second rotating rod 24 .

[0027] By adopting the above technical solution, the motor 33 is provided to provide power to the first rotating rod 19 and the second rotating rod 24, so that the first rotating rod 19 and the second rotating rod 24 work to perform loading and unloading operations.

[0028] A horizontally arranged baffle plate 4 is fixedly disposed on one side of the placement frame 11 facing the fixing frame 12 and at both ends of the through slot 15 .

[0029] By adopting the above technical solution, the baffle 4 can ensure that when the first cross bar 14 pushes the plate to be stamped into the fixed frame 12, the movement is stable and the deviation of the movement is avoided to affect the subsequent processing.

[0030] A groove 41 is formed on the opposite side of the two baffles 4 , a positioning plate 42 is arranged in the groove 41 , a cylinder 43 is installed on the upper surface of the workbench 1 near the positioning plate 42 , and the output end of the cylinder 43 passes through the groove 41 and is inserted on the positioning plate 42 .

[0034] A transverse plate 141 is fixedly disposed on both sides of the first transverse rod 14 .

[0035] By adopting the above technical solution, the horizontal plate 141 is used to shield the upper plate in the placement frame 11, increasing the contact area of ​​the first cross bar 14, thereby preventing the upper plate from falling and tilting when the first cross bar 14 moves back, affecting the next loading.

[0036] A protruding limiting strip 171 is fixedly provided on the side walls of the first tooth plate 17 and the second tooth plate 22 . The limiting strip 171 can be inserted into the slide groove 16 by sliding along with the first tooth plate 17 and the second tooth plate 22 .

[0037] By adopting the above technical solution, the limiting strip 171 can be provided so that the first tooth plate 17 and the second tooth plate 22 can be stably provided to slide in the slide groove 16, thereby ensuring the stability of the movement of the first cross bar 14 and the second cross bar 2.

[0038] Working principle: In actual use, the motor 33 cooperates with the belt 32 and the two meshing driving gears 31 to make the first rotating rod 19 and the second rotating rod 24 rotate towards each other at the same time. At this time, the first rotating rod 19 and the second rotating rod 24 will respectively drive the first gear 18 and the second gear 23 to rotate towards each other, and the first gear 18 and the second gear 23 will simultaneously drive the first tooth plate 17 and the second tooth plate 22 to move towards each other, and the first tooth plate 17 will drive the first cross bar 14 fixed thereto to move, and at this time the top end of the first cross bar 14 will push the plate to be stamped located at the bottom of the placement frame 11 to move toward the fixed frame 12, and at this time the second tooth plate 22 will drive the second cross bar 2 to move toward the fixed frame 12, and at this time the pushed plate will move to the bottom of the stamping device body 13 on the fixed frame 12 and the second cross bar 2 will abut against the plate to limit the plate and complete the loading, and then the cylinder 43 pushes the positioning plate 42 to move the plate moved below the stamping device body 13 The clamping and positioning are carried out to avoid shaking during stamping that affects the stamping effect. The stamping device body 13 will work to perform stamping operations on the positioned sheet. After the stamping is completed, the motor 33 will be reversed. At this time, the first rotating rod 19 and the second rotating rod 24 will move back to back at the same time. The first tooth plate 17 and the second tooth plate 22 will drive the first cross bar 14 and the second cross bar 2 to move away from the fixed frame 12 at the same time. At this time, the first cross bar 14 will move to the initial state, that is, move to the outside of the placement frame 11. At this time, the bottom sheet in the placement frame 11 will be unloaded and wait for the next loading. When the second cross bar 2 is away from the fixed frame 12, the pneumatic suction cup 21 will drive the stamped sheet out of the fixed frame 12, thereby completing the unloading operation. Through the above operation, the sheet required for stamping can be automatically loaded and unloaded, without the need for manual operation of loading and fixing and unloading disassembly by staff, thereby reducing manual operation, improving safety factor, facilitating loading and unloading, and improving work efficiency.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
