[0044] Further, the buffer mechanism 3 is used in the stamping part 31, and the hydraulic lever 311 is activated to drive the auxiliary plate 312 to move, and the movement of the auxiliary plate 312 further drives the buffer part 32 to move as a whole, so that the upper die 323 can gradually approach and stamp with the lower die 225. During the stamping process, the buffer spring 321 is compressed to absorb and disperse the impact force. In order to ensure the smoothness of the buffering process, the light rod 313 slides on the inner wall of the auxiliary plate 312, which helps to maintain the stability of the buffer part 32.
