Abstract：

The designing process of drawing die for complex surface drawing part in designing the drawing model of the automotive hood outer panel surface and the design method and principle were studied.The stamping process using the sheet metal forming analysis software Dynaform was simulated.The reason causing quality defect in simulation,such as cracking and wrinkle etc.,was investigated.Based on these reasons,the design of drawing die surface for automobile hood outer panel was optimized.According to the simulated results,the qualified drawing die was made,which had a instructing meaning for the design and manufacture of drawing die for complex surface drawing part.
