基于CAE技术的拉深模具压料筋结构参数设计

Design of structural parameter of deep drawing die press rib based on CAE technology

本文从压料筋作用原理、压料筋的形状与阻力组成出发,具体讨论了利用冲压CAE分析技术设计压料筋的方法。采用等效压料筋模型,确定压料筋各个结构参数的合理组合。为合理设计复杂冲压件拉深模具压料筋各结构参数提供了方法。

Starting from the action principle and the shape & resistance composition of the press rib, the design method of press rib by use of stamping CAE analysis technology has been discussed in the text. The equivalent pressure rib model has been used to determine the reasonable combination of various structural parameters of the pressure rib, which provides a method for rationally designing the structural parameters of the press rib of the drawing die for complex stamping parts.
