Lacking a buffer mechanism, the key components of the die are easily damaged by impact under continuous high-strength punch press operation, accelerating the fatigue aging process of the die. Frequent replacement of the die not only increases production costs, but also affects the continuity and efficiency of the production line. SUMMARY
