Abstract：

The deep drawing of tank cover was simulated by finite element software Dynaform, and the defects of cracks and wrinkles were analyzed. The die clearance, stamping speed and blank holder force were chosen as process parameters to carry out orthogonal experiment and optimization of parameters, and the sequence of influence on the maximum thinning rate of tank cover was obtained by range analysis of orthogonal experiment as die clearance, blank holder force and stamping speed. Furthermore, the influences of die clearance and blank holder force on the maximum thinning rate of sheet metal are significant. The simulation results show that the maximum thinning rate and the maximum thickening rate are 13.23% and 11.12% respectively under the optimal process parameters with die clearance 1.5t, stamping speed 3000 mm·s-1 and blank holder force 60 kN. The optimized process scheme was verified by experiment, and experimental results were obtained that the maximum thinning rate and the maximum thickening rate are 14.87% and 12.64% respectively. As a result, the simulation results are in good agreement with the experimental results, and the forming quality of tank cover is good.
