Abstract：

The shape of the car left and right rear wheel cover is complex, and the drawing process is difficult, so it occurs to crack and wrinkle easily and obtains a high rejection rate when it is drawing. For the above problems, based on the structure features of the car left and right rear wheel, its process features were analyzed, and the key design issues of die were given. Then, the drawing direction was determined, and the key factors of selection were pointed out. Furthermore, the die structure was optimized, and the features of die structure and the working principle of die were analyzed. In the process of die design, the stamping was realized by double action drawing die to make the blank and punch contact and scatter. Therefore, the crack and wrinkling phenomenon were avoided, and the pass rate of produce was improved. So, the optimized drawing die simplifies the die structure and saves costs for manufacture.
