An electric push rod 13 is fixedly connected to the bottom of the second U-shaped plate 14. A first U-shaped plate 12 is fixedly connected to the extended end of the electric push rod 13. A stamping head 11 is provided at the bottom of the first U-shaped plate 12. Both ends of the bottom of the first U-shaped plate 12 penetrate the processing table 1 and are slidably connected to the processing table 1. Multiple punch holes 10 are opened on the side wall of the processing table 1. The stamping head 11 is located directly above the punch holes 10.

[0030] The bottom of the processing table 1 is fixedly connected to a vertical rod 4 through a feeding structure. A driving block 19 is slidably connected to the outer side wall of the vertical rod 4. A connecting plate 3 is fixedly connected to both sides of the lower end of the first U-shaped plate 12. The two connecting plates 3 are fixedly connected to the two sides of the driving block 19 respectively. A driving rod 17 is rotatably connected to both ends of the driving block 19.

[0031] The processing table 1 has two sliding grooves 22 on its side wall. Each sliding groove 22 is fixedly connected to a sliding rod 15. Each sliding rod 15 is slidably connected to a sliding block 16 on its outer side wall. The two sliding blocks 16 are slidably connected to the two sliding grooves 22 respectively. One end of each of the two drive rods 17 is rotatably connected to the bottom of the two sliding blocks 16 respectively. The top of the two sliding blocks 16 is connected to two arc-shaped clamps 9 through an adjustment structure. Each arc-shaped clamp 9 has a rubber pad on its side wall. The elasticity of the rubber pad can provide a certain buffering performance for the punching sheet.

[0032] Please see Figures 2-3 The unloading structure includes a mounting plate 18, which is fixedly connected to the bottom side wall of the processing table 1. An unloading plate 21 is fixedly connected to the side wall of the mounting plate 18. The top of the unloading plate 21 is inclined. The unloading plate 21 is located at the bottom of multiple punch holes 10. A vertical rod 4 is fixedly connected to the bottom side wall of the unloading plate 21. Baffles 20 are fixedly connected to both sides of the top of the unloading plate 21. The stamped debris can be discharged through the multiple punch holes 10 and fall to the top of the unloading plate 21. It slides through the inclined side wall of the unloading plate 21 into the collection box 2 for collection.

[0033] Please see Figures 1-4 The adjustment structure includes two sliding plates 8, which are fixedly connected to the top side walls of two sliding blocks 16. Bolts 6 are threadedly connected to the side walls of both sliding plates 8.

[0036] The working principle of this utility model is as follows: When stamping is required, the stamping sheet is placed between two arc-shaped clamping plates 9, and then the electric push rod 13 is activated. The extended end of the electric push rod 13 drives the first U-shaped plate 12 and the stamping head 11 to move downward. When the first U-shaped plate 12 moves, it can drive the two connecting plates 3 to move downward. The two connecting plates 3 simultaneously drive the driving block 19 to move downward. When the driving block 19 moves, it can drive the two driving rods 17 to move. The two driving rods 17 drive the two sliding blocks 16 to move. The two sliding blocks 16 drive the two arc-shaped clamping plates 9 to move through the sliding plate 8, so that the two... The arc-shaped clamping plates 9 move relative to each other to clamp and fix the punch. When the two arc-shaped clamping plates 9 clamp and fix the punch, the punching head 11 moves to the top of the punch and abuts against the top of the punch. The punch can be clamped and fixed at the same time as the punching head 11 moves downward to process, without the need for other operations to clamp the punch. This reduces the manufacturing cost of the device and improves the processing efficiency of the punch. Then, the punch is punched by the punching head 11. The punched debris can be discharged through multiple punch holes 10 and fall to the top of the feed plate 21. It slides through the inclined side wall of the feed plate 21 into the collection box 2 for collection.

[0037] By rotating bolt 6, the arc-shaped clamping plate 9 can be moved, thereby adjusting the distance between the two arc-shaped clamping plates 9. This facilitates the clamping of punches of different sizes and improves the applicability of the device.
