Abstract：

For reducing the cost of outer panel stamping production, the feasibility of the substitution for tail-gate material was analyzed. Then, the original DC54D+ZF was replaced by DC53D+ZF, the drawing process was numerically simulated by Autoform software. However, the satisfied part could not be obtained by adjusting the blank-holder force and drawbead resistance under a constant stamping speed. Therefore, the drawing experiments for substitution material DC53D+ZF were carried out by mechanical press, and the results were consistent with the simulation results. Furthermore, the drawing experiments for substitution material DC53D+ZF were carried out by servo press, and the qualified parts meeting the requirements could be obtained by reducing the drawing speed. And the servo drawing curve of tail-gate outer was fit by setting the control parameters of mechanical transmission and outer panel drawing process.
