Abstract：

In order to solve the problems such as cracking, wrinkling and springback of aluminum alloy automobile cover panel during stamping production process, for an aluminum alloy automobile side outer panel, the processability of part was analyzed. Then, the process supplementary modeling and sheet shape were quickly designed by software Autoform, and the whole stamping process simulation was carried out on this basis. The simulation results show that the optimization of the original part modeling in synchronous engineering stage can avoid the stamping defects in the design, spheroidizing the fillet in the cracked area and designing a smooth transition in the continuous step modeling can alleviate the cracking risk, setting additional wrinkle absorption modeling and flanging gap in the wrinkle area can alleviate wrinkling, designing stiffeners and adding structural constraints can reduce the springback amount, and avoiding the interference of modeling features can reduce the deformation defects of the stamping surface. Finally, the optimized part is successfully manufactured with good quality, which proves that this method can effectively reduce the time and cost of later stamping die development, improve the quality of product, and provide a good reference for structural improvement of similar parts.
