【 摘 要 】

Based on the basic principles of production process and process design for automotive panels, this project develops the stamping process for automotive rear wheel cover panels, and uses CATIA software to draw out the three-dimensional digital models of parts, and then uses the Autoform software to perform numerical simulation analysis. The software analyzes and calculates the stamping direction, the pressing surface, the process supplementary surface, the blank size, the forming limit diagram of the part, the main strain diagram, and the thickness variation, and finally optimizes the blank holder force, friction coefficient, and blank size. To Get the best punch results.
