Abstract：

Due to the small elastic modulus of aluminum alloy materials and the poor forming properties of stamping at room temperature, for aluminum alloy automobile engine outer panel, its stamping process was analyzed by software Autoform, and the influences of stamping process parameters on the thinning rate and springback of parts were studied by optimizing the profile structure to improve forming quality of part. The results show that when the smaller blank holder force is applied, the thinning of sheet is smaller. However, within a certain range, the springback of part is reduced with the increasing of blank holder force. Finally, through the profile compensation of mold and the adjustment of process parameters, the springback of part is reduced efficiently. Based on the above results, a stamping test of engine outer panel was conducted. And the parts meet the production requirements by mold debugging.
