By controlling the air cylinder 41 to make the top block 42 translate downward, the top block 42 contacts with the corresponding stamping part 44 and applies downward pressure to it, so that the stamping part 44 translates downward and applies pressure to the chain sheet on the die base assembly 6 to realize the stamping work;

[0023] When the stamping part 44 needs to be replaced, the driving mechanism 5 drives the rotating shaft 3 to rotate a certain angle, which makes the mounting plate 43 rotate synchronously by a corresponding angle, so that all the stamping parts 44 rotate circumferentially and change positions, so that different stamping parts 44 can be replaced to the bottom of the top block 42, so that the stamping parts 44 can be replaced without stopping the machine, which greatly improves the work efficiency.

[0024] Among them, the stamping part 44 includes a sliding rod 441, which passes through the mounting plate 43 and is slidably connected to the mounting plate 43. The top of the sliding rod 441 is fixedly connected to a docking seat 442, and the top block 42 is slidably matched with the docking seat 442. The bottom end of the sliding rod 441 is fixedly connected to a die head 443. A return spring 444 is sleeved on the sliding rod 441.

The diameters of several die heads 443 are different.

[0025] During stamping, the cylinder 41 is controlled to make the top block 42 translate downward, so that the top block 42 comes into contact with the docking seat 442, and the docking seat 442 is subjected to downward pressure to drive the slide bar 441 to slide downward, so that the die head 443 translates downward to apply pressure to the chain plate to realize the stamping work, and the return spring 444 can play a buffering role, avoiding the problem of damage to the chain plate due to excessive impact force.

[0026] Among them, the die base assembly 6 includes a die base 61, which is fixedly connected to the top of the support platform 1.
