摘要：

为降低外覆盖件冲压生产成本，对尾门外板材质替换进行可行性分析。采用DC53D+ZF替换原有的DC54D+ZF板材，利用Autoform软件对其拉深成形过程进行数值模拟，在冲压速度恒定的情况下，调整压边力和拉深筋阻力无法得到满足要求的成形件；利用机械压力机对替换材质DC53D+ZF进行拉深实验，实验结果与模拟结果一致。之后利用伺服压力机对替换材质进行拉深实验，通过降低拉深速度可以得到满足质量要求的合格制件，并通过设置机械手传输和覆盖件拉深成形关键点参数，拟合得到尾门外板伺服拉深曲线。

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.
