Abstract：The car oil pan will crack and wrinkle during stamping and forming process, this paper analysis the CAE process of car oil pan based on Autoform software, and eliminates the defects by using the drawbead, increasing the punch radius and other methods. It designs a set of reasonable forming process and continuous die for car oil pan, the rationality of die structure design is verified by stamping experiment. Cold stamping die CAD/CAM/CAE analysis can improve the quality of mold design greatly, shorten the design cycle and improve the production efficiency
