Abstract：

For optimizing the process design of hot stamping parts to enhance the part performance, reduce the production costs, and improve the production efficiency, the process flow optimization, the die design improvement and the material utilization enhancement were focused on. The impact of process parameters (such as billet heating temperature, forming temperature and stamping speed) on the quality of hot stamping parts was systematically analyzed using the orthogonal test method, and the priority order and optimal combination of each factor were clarified by combining the simulation analysis. Finally, the optimal process parameter combination is determined as: the billet heating temperature of 930 ℃, the forming temperature of 780 ℃, and the stamping speed of 40 mm·s-1. This process parameter combination effectively improves the dimensional accuracy, surface quality and mechanical properties of parts. The research provides highly efficient process design and simulation analysis methods for engineering technicians, which is of significant importance for technological advancement in the automotive lightweighting field.
