摘要
分析了前盖内板冲压模具设计中坯料预冲孔数量及形状对拉深件质量的影响,将有限元模拟分析与模具调试相结合,得到了优化的预冲孔方案、缩短了模具制造周期。
The effect of shape and number of pre-pierced holes in blank on forming quality of front hut inner has been discussed.Optimized solution has been obtained based upon FEM simulation and try out,resulting in reduction of die production cycle.
