Abstract：

The original stamping process for vehicle fender was analyzed. In order to overcome the defects of original process,a new scheme was proposed with emphasis on introduction to the design of the drawing die capable of forming four different parts at one time. A numerical simulation was conducted on the improved forming scheme using FEA software AutoForm. After the establishment way and shape size of blank optimized，the local deficient formation and breakage before optimization were solved. The results verify the rationality and feasibility of the new stamping scheme. Adopting the process can not only greatly increase the material utilization rate and reduce die cost for the elimination of one blanking die, but also shorten the lead time of die design and enhance the overall efficiency of production.
