By placing the metal plate above the support plate 22, the pressure on the metal plate during punching can be dispersed, the local stress can be reduced, and the bending deformation of the metal plate can be reduced. Then, the position to be punched is placed at the bottom of the punch 5, and then the metal plate is clamped and fixed by the clamping assembly.

[0033] Reference Figure 1-3The clamping assembly includes a threaded rod 13, which is arranged in the middle of the vertical plate 10, one end of the threaded rod 13 is fixedly connected to the rotating wheel 9, and the other end of the threaded rod 13 is rotatably connected to the connecting block 15, one end of the connecting block 15 is fixedly connected to the clamping block 11, and two connecting plates 16 are respectively fixedly connected to the upper and lower ends of the connecting block 15. By rotating the rotating wheel 9, the rotating wheel 9 drives the threaded rod 13 to rotate synchronously, so that the threaded rod 13 can move in the middle of the vertical plate 10, and then drive the connecting block 15 and the clamping block 11 to move synchronously above the support plate 22 to achieve the clamping of the metal plate. The buckle assembly includes a pull block 18, which is fixedly connected to one end of the plug rod 21, and the other end of the plug rod 21 The end is fixedly connected with an insert block 19, and the insert block 19 is slidably connected to the middle part of the clamping block 11. The outer periphery of the insert rod 21 is fixedly connected with a pressure block 17, and the outer periphery of the insert rod 21 is sleeved with a spring 20. By pulling the pulling block 18 upward, the insert rod 21 drives the pressure block 17 to move synchronously, and when the pressure block 17 moves upward, the pressure block 17 is squeezed to make the insert block 19 slide to the middle part of the connecting plate 16, and then a new clamping block 11 is placed on one side of the connecting block 15. After the pulling block 18 is released, the pressure block 17 and the insert block 19 are reset under the action of the spring 20, so that the insert block 19 slides to the middle part of the clamping block 11 to limit the clamping block 11, thereby achieving the fixation between the connecting block 15 and the clamping block 11.

[0034] Reference Figure 1 and Figure 4 A collecting box 7 is arranged below the workbench 3, a filter plate 25 is arranged in the middle of the collecting box 7, an exhaust fan 23 is fixedly connected to the bottom of the workbench 3, a suction pipe 6 is arranged in the middle of the collecting box 7, a sealing strip 26 is fixedly connected to the top of the collecting box 7, and the sealing strip 26 is arranged between the collecting box 7 and the workbench 3, a chute 14 is opened at the bottom of the workbench 3, a slider 24 is fixedly connected to the top of the collecting box 7, and the slider 24 is slidably connected to the middle of the chute 14, and a handle 8 is rotatably connected to the front side of the collecting box 7 By setting the collecting box 7 at the bottom of the punching hole 27, part of the debris generated during punching falls directly into the middle of the collecting box 7, and the other part of the debris is absorbed by the exhaust fan 23 and the suction pipe 6 above the support plate 22 and then enters the middle of the collecting box 7. When the work is completed, one end of the suction pipe 6 can be removed from the middle of the collecting box 7, and then the handle 8 is pulled to make the slider 24 slide in the middle of the slide groove 14, and then the debris collected in the middle of the collecting box 7 can be uniformly processed.

[0035] Working principle: by placing the metal plate on the support plate 22, and then placing the position to be punched under the punch 5, and then clamping the metal plate by rotating the wheel 9, and then driving the punch 5 to punch the metal plate by the cylinder 1, and opening a punching hole 27 in the middle of the mold 12 and the workbench 3, so that part of the debris generated by the punching falls directly into the middle of the collection box 7, and then through the action of the exhaust fan 23 and the suction pipe 6, another part of the debris remaining above the mold 12 is absorbed into the middle of the collection box 7. After using it for a period of time, it is necessary to regularly check the wear of the clamping block 11. When the clamping block 11 needs to be replaced, by pulling the pull block 18 upwards, the pull block 18 drives the insert block 19 to slide out from the middle of the clamping block 11, thereby realizing the disassembly of the clamping block 11 to solve the problem that the fixture cannot be partially replaced.
