Abstract：

For the wave spring sheet of clutch disk, it was simulated the fatigue life of blanking punch by finite element software ANSYS Workbench, analyzed the stress distribution of blanking punch, and studied the influence of process parameters (the diameter of vent in the blanking punch, fillet radius and length of blanking punch) on the fatigue life of wave spring sheet. The simulation results show that when both the blanking punch without vent and the blanking die with anti-waste floating are used, the fillet radius of blanking punch and the length of blanking are optimized to R1.2 mm and 3.5 mm respectively, and the fatigue life of blanking punch increases from 24820 times to 47041 times. In addition, the progressive die of wave spring sheet is designed to verify the simulation result, the life of blanking punch after optimization can reach 42948 times with a 9.53% error between simulated value and experimental value. Therefore, the above process effectively saves the production costs of enterprises.
