According to the size, structure and batch production of lock blade part, the stamping process of multi-position progressive die for part was analyzed. In order to ensure the smooth and good flow of the forming process, three work stations were designed to complete the process cut, and the layout scheme of punching, punching shearing, forming and shaping was determined. Then, the structures of die and main parts were designed, with the internal and external guide mechanisms and the elastic stripper device for stripper and holder by guide plate combining guide nail to positioning, which ensures the accuracy of product. After processing the die, a punching test is carried out. The result shows that the layout program and die structures are reasonable, and the parts with qualified dimension and precision are obtained.
