Abstract：

For the middle reinforce plate of automobile front rail with problems of wrinkling and fracture in the stamping forming of high strength steel part, the stamping process of the part was simulated by finite element method so as to avoid these defects and decrease the development risk of the die. The high strength steel part produced serious springback after deformation, so the multiple iterations springback compensation was applied to dies. Therefore, the part area was compensated directly, and the binder area was compensated by fixed compensation method, and the transition area between the part and binder was taken as a transitional region in the compensation process. The qualified rate of this part was 80.7% after compensation. The simulation results are in accordance with the experimental results, and it shows that the springback compensation method is feasible and can reduce the die tryout time and manufacture cycle.
