Abstract：

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.
