Abstract：

Aiming at the characteristics of the thin thickness and high precision for sealing fixing cover with asymmetric flange，the stamping process of the product was analyzed. The progressive die with thirteen positions was designed. The working process of the die was illustrated in detail. The matters needing attention in stamping production were pointed out. The specific technical measures adopted can avoid the crack and unqualified size of products. The two years production practice shows that the stamping process design is reasonable，the reliable structure of die is convenient to be repaired and can guarantee the quality of products which should fully meet customer requirements.
