Abstract：

Based on the analysis of fender structure and process characteristics, five processes of stamping fender were formulated. Combined with the simulation of Autoform software and design experience, three-dimension drawing process model for front fender was set up by UG software，the causes of forming defects as drive line and deficient rigidity appeared during fender molding were analyzed，and corresponding precaution measures were given. The problem of drive line was solved by adjusting stamping direction, the problem of skid line was solved by adjusting feed rate,and the strength and rigidity were improved by adjusting draw bead and adding convex closure. The stamping processes were simulated，which realized the optimization of processing supplement. The die adjustment shows that the design and optimization of stamping process is reasonable,which eliminates the defects and ensures the surface accuracy and forming quality of the products.
