Abstract：

The traditional cold stamping of deep-cone shaped charge liner with changeable wall thickness is of long designing time, complicated process and low stock utilization. The above manufacturing process was improved by changing the continuous drawing of the cone shape into that of the cylinder shape. Comparing with the cone shape drawing, the drawing cylinder shape had the characteristics of less suspended material, larger forced area and smaller stress. Further, the continuous stamping process was simulated and analyzed by Dynaform, and the deformation of each part was shown by forming limit diagram. Therefore, the designing efficiency of cold stamping process was improved. As a result, five continuous drawings of the cylinder shape can meet the size requirement after optimizing the stamping process. At last, the deep-cone shaped charge liner with changeable wall thickness of good surface quality was successfully manufactured in the cold stamping equipment by the improved process.
