摘要：

非标斜楔是汽车覆盖件冲压模具设计和制造中最复杂的部分，传统的设计方法非常复杂繁琐，导致设计周期长，而且质量无法保证。因此，提出一种基于子结构历史设计案例重用的非标斜楔快速设计方法。将非标斜楔及其周围相关的零件从模具中截取出来，并为其添加属性信息，形成被重用的非标斜楔子结构。新斜楔设计时，通过零件的功能特征信息和工艺参数与数据库中的模型属性进行匹配，搜索相符的子结构，并将其重用到新的模具设计中。在重用的过程中，子结构被成组装配到新的设计模型中，且可以进行位置的精确调整。实例表明，该设计方法可以实现非标斜楔的快速设计，有效提高了设计效率和设计质量。

Non-standard wedge is one of the most complex structures in the design and manufacture of stamping dies for automotive panel. However, the traditional design of non-standard wedge is very complicated, which leads to a long design period and the design quality cannot be guaranteed. Therefore, a new design method of non-standard wedge was proposed based on the substructure reuse of historical design cases. Furthermore, the non-standard wedge and related parts around were cut out, and the attribute information was added to form a reuse substructure. In the new design, the appropriate substructures were reused and quickly matched by searching the functional feature and process parameters in the case database. Moreover, in the process of reusing, the substructure was assembled into a new model and re-located by fine adjustment. The example shows that the new design of complex non-standard wedge can realize its quick design, save the design time and improve the design quality significantly.
