HUANG Zhao-ming, WANG Li

Taking the front panel of a car as the research object, the whole process forming process plan of the parts is analyzed and planned. Based on this scheme, the initial sheet profile is calculated by one-step method. The whole process of stamping forming is simulated and analyzed based on AutoForm software and the forming defects are predicted and the forming process is optimized. The simulation and optimization results show that the whole process multi-step stamping simulation can obtain the process die surface quickly and effectively, and realize the seamless joint between the whole process die surface design and multi-step stamping simulation and optimization design. Reasonable product process optimization and trimming line optimization reduce the cracking phenomenon and actual boundary contour error.
