Research on Auto Cover Drawing Die Design BASED on NX

摘要

According to characters of auto covering parts such as large size, thin thickness, complexity in shape, low degree of standardization and expressed by model, etc. This paper put forward the drawing die design process of auto covering parts based on NX software. The assembly drawing of the auto covering part drawing die was shown in detail. In accordance to the mold design process, the digitized model was parametrically designed. The competitiveness of the auto covering part mold manufacturing enterprises was significantly improved with the application of 3D mold dynamic simulation s and automatic forming line simulation.
