By analyzing stamping processes of the complicated stamping work-piece,Shapes and dimensions of the semi-finished products of every stamping process are defined preliminarily.According to the shapes and the dimensions of the semi-finished products,the simulations for the stamping processes are carried out.The reasonableness of the stamping processes is analyzed.The suitable stamping scheme is obtained by means of modifying the parameters of the semi-finished products.The die sets are fabricated based on the scheme and the qualified product can be stamped out.This paper described the dynamic simulation method of the multi-step forming and the design approach of the stamping process.It makes die sets designed successful at the presence of time saved and cost effective.
