Abstract：

In order to explore the optimal combination of process parameters for the tank head stamping, improve efficiency and save time, the Dynaform finite element software was used for numerical simulation. Then, the three factors of punching speed, blank holder force and friction coefficient were selected as optimization variables, and the maximum thinning rate, the maximum thickening rate and the maximum springback amount of head were used as forming indicators. Furthermore, the orthogonal test scheme was designed, and the optimal combination of process parameters with the punching speed of 4000 mm·s-1,the blank holder force of 590 kN and the friction coefficient of 0.08 was determined by range analysis and variance analysis. Finally, the actual production test was carried out according to the optimal combination of process parameters, and the ovality of head port was used as the verification standard. The results show that the simulation results are consistent with the actual production results, and the final forming quality of head meets the requirements.
