摘　　要：覆盖件模具的设计和制造是开发汽车新车型的“瓶颈”环节。介绍了产品装配模型并对其进行了描述 ,然后应用基于特征的三维参数化建模技术 ,针对某一几何拓扑关系类似的系列覆盖件产品中的一典型件 ,建立其参数化模具结构装配模型并实现模具结构的变形设计 ,最后以汽车前框架下横梁零件为例进行相关拉延模结构变形设计。结果表明 ,应用本文提出的设计方法 。Design and manufacture of automobile panel die is a 'bottleneck' in development of a new type of automobile. The assembly model is firstly introduced and described in this paper. Through 3D parametrization technology, a assembly model of drawing dies structure for a typical drawpiece selected from a series of automobile panels with similar topology was established, and the variant design of die structure was realized. As an example of front low crossbeam, the variant design of drawing dies structure based on the assembly model was successfully fulfilled. The research results proved that the method could greatly improve design efficiency of panel drawing dies structure.
