[0032] Preferably, the punching cylinder 6 comprises a threaded cover 61, a lifting rod 62, an impact block 63, a pressure plate 64, a compression spring 65, a counterweight cylinder 66, a counterweight cover 67, a neodymium magnet 68 and a counterweight plate 69, wherein the counterweight cylinder 66, the counterweight cover 67, the neodymium magnet 68 and the counterweight plate 69 are movably placed inside the punching cylinder 6, wherein the neodymium magnet 68 is located inside the counterweight cylinder 66 and is limited by the counterweight cover 67, and the surfaces of the counterweight cover 67 and the counterweight cylinder 66 are superimposed on each other and closely attached to multiple counterweight plates 69, the two ends of the punching cylinder 6 are threadedly sleeved with threaded covers 61, the middle of the threaded cover 61 is movably penetrated by a lifting rod 62, the two ends of the lifting rod 62 are respectively fixedly provided with an impact block 63 and a pressure plate 64, and a compression spring 65 supporting the pressure plate 64 is fixed on the threaded cover 61;

[0033] In the specific implementation, the punching cylinder 6 is driven by the transmission shaft 4 to rotate rapidly 180 degrees, as shown in the attached manual. Figure 2 As shown, the counterweight cylinder 66, the counterweight cover 67, the neodymium magnet 68 and the counterweight plate 69 are synchronously moved downward and suspended above the inside of the stamping cylinder 6. Then, the counterweight cylinder 66, the counterweight cover 67, the neodymium magnet 68 and the counterweight plate 69 are synchronously moved downward. The gravity of the counterweight cylinder 66, the counterweight cover 67, the neodymium magnet 68 and the counterweight plate 69 acts on the pressure plate 64, causing the lifting rod 62, the impact block 63 and the pressure plate 64 to move downward synchronously. The impact block 63 vertically impacts the upper stamping ring 11 and the stamping block 14 of the force disk 12 to provide downward force for stamping.

The transmission shaft 4 is in the middle of the fixed bearing 5 so that the punching cylinder 6 can rotate and is supported during the rotation process. The use of the fixed bearing 5 can reduce friction.

[0036] Preferably, the stamping ring 11 is located directly above the mounting tube 8, and four stamping blocks 14 are arranged in a cross around the inner wall of the stamping ring 11. The ends of the four stamping blocks 14 are inclined.

The mounting tube 8 is small at the top and large at the bottom and is truncated into a cone. The end of the stamping block 14 protrudes from the bottom of the stamping ring 11. The stamping ring 11 is against the nut of the four-claw nail. The stamping block 14 cuts off a part of the nut to form a claw and pushes the claw to bend vertically.

[0038] Preferably, a docking hole is provided in the middle of one side of the counterweight plate 69, and a docking block is integrally formed in the middle of the other side of the counterweight plate 69. The docking block is matched with the docking hole so that when the counterweight plates 69 are stacked on each other, the edges of the counterweight plates 69 remain aligned, so that the counterweight plates 69 are firmly fixed to each other.

[0039] Preferably, the counterweight cylinder 66, the counterweight cover 67, the neodymium magnet 68 and the counterweight plate 69 can freely fall on the inner wall of the punch cylinder 6 to generate a downward force acting on the pressure plate 64. The pressure plate 64 rests on the compression spring 65, and the compression spring 65 can push the pressure plate 64 down and prevent the pressure plate 64 from colliding with the threaded cover 61.

[0040] Preferably, the fixed bearing 5 is symmetrically arranged on both sides of the punching cylinder 6, the return spring 13 is symmetrically arranged on both sides of the sliding rod 9, the sliding rod 9 moves up and down in the middle of the sliding tube 7, and the mounting cylinder 8 limits the sliding rod 9 so that the sliding rod 9 moves vertically up and down.

[0041] Preferably, the top of the force disk 12 is concave downward in an arc shape, and the surface of the impact block 63 is convex outward in an arc shape. The shape of the top of the force disk 12 is matched with the shape of the impact block 63, so that the impact block 63 slides down from the top of the force disk 12 very quickly.

[0042] In the present invention, when in use, first, insert the four-claw nail into the middle of the installation cylinder 8, and the servo motor 3 drives the rotating shaft 4 to rotate 180 degrees, so that the punching cylinder 6 and the transmission shaft 4 rotate 180 degrees synchronously and quickly, as shown in the attached manual. Figure 2As shown, the counterweight cylinder 66, the counterweight cover 67, the neodymium magnet 68 and the counterweight plate 69 are suspended above the inside of the punching cylinder 6, and then the counterweight cylinder 66, the counterweight cover 67, the neodymium magnet 68 and the counterweight plate 69 move downward synchronously due to the action of gravity. The gravity of the counterweight cylinder 66, the counterweight cover 67, the neodymium magnet 68 and the counterweight plate 69 acts on the pressure plate 64, so that the lifting rod 62, the impact block 63 and the pressure plate 64 move downward synchronously, the pressure plate 64 abuts on the compression spring 65 to be compressed, and the impact block 63 vertically impacts on the force plate 12, so that the sliding rod 9, the mounting plate 10, the punching ring 11, the force plate 12 and the punching block 14 move downward synchronously, the force plate 12 abuts on the reset spring 13 to be compressed, and the punching block 14 cuts off the four-claw nail nut to form a claw, and then the punching block 14 bends the claw vertically, as shown in the attached manual. Figure 1 As shown, the stamping work is completed.
