摘要：

起皱和拉裂是印涂铝盖在冲压拉深过程中的两大主要缺陷，合适的压边力对防止起皱和拉裂具有十分重要的作用。实际中，通常采用理论计算和模具调试的方法来获得合适的压边力数值，但理论计算方法计算复杂、可操作性差，而模具调试繁琐且费时费工。针对这一问题，以非线性有限元分析软件Dynaform为平台，对印涂铝盖冲压拉深工艺过程和压边力进行数值模拟和理论分析，确定了压边力的合理范围，并根据压边力范围试冲产品以确定最佳压边力。结果表明，1716印涂铝盖首次拉深的压边力数值的合理范围为7～8.8 kN，最理想的压边力数值在8.8 kN附近。该方法减少了压边力调试的盲目性，缩短了模具调试时间，减少了模具调试难度，最终达到降低产品制造成本的目的。

The wrinking and cracking are the two main defects of the printing aluminium cover in the drawing process，so the proper blank holder force plays an important role to prevent wrinkling and cracking. In practice, the proper blank holder force was usually obtained by theoretical calculation and die adjustment. However, the theoretical calculation method has complex calculation and poor operability and the die adjustment is complicated and time-consuming. Based on nonlinear finite element analysis software Dynaform，the printing aluminum cover drawing process and blank holder force were numerically simulated and theoretically analyzed to determine a reasonable range of blank holder force. And then the optimum blank holder force was confirmed by drawing experiment based on this range. The results show that the reasonable range of blank holder force during the first drawing for 1716 printing aluminum cover is 7-8.8 kN, and the ideal blank holder force is about 8.8 kN. The method reduces the blindness of blank holder force adjustment, shortenes the die adjustment time and reduces the die adjustment difficulty. At last, the manufacturing cost of product was reduced.
