Abstract：

For the problem of serious wear of stamping die for an aluminum alloy structural part, based on the Archard modified model, the stamping process was numerically simulated by software DEFORM, the forming condition of part and the wear condition of die were intuitively understood, and the main factors affecting the service life of die were analyzed. Then, the significance of the influences of blank holder force, stamping speed, sheet heating temperature and die preheating temperature on the die wear was studied by orthogonal test, and the optimal parameters combination was obtained with the goal of minimizing die wear. Finally, based on the optimal parameters combination, the numerical simulation and process test show that the die wear is reduced by 58.8% compared with the initial process, and the error between the predicted and actual values of die life is only 2.83%. Thus, the simulation results are accurate and feasible, and the cost of die test is effectively reduced.
