Abstract：

For the seat support plate in the automobile, the finite element model of deep drawing was established by software Autoform, and the forming progress and springback were analyzed. Then, for the excessive springback amount in drawing process, the orthogonal test was carried out with the blank holder forces, friction coefficients, punch speed and die clearance as factors. Furthermore, the influences of the parameters on springback amount were studied, and the optimized combination parameters were obtained with the blank hold force 250 kN, friction coefficient 0.08, die clearance 1.2 mm and forming speed 4000 mm·s-1. Thus, the experiment results are in good agreement with the simulation results, and the part quality is completely satisfied with the design requirements.
