覆盖件拉延模工艺补充面及压料面参数化设计研究

Addendum And Binder Surface Parametric Design for Automotive Panel Drawing Die

工艺补充面和压料面的设计是否合理 ,是保证覆盖件成形质量的重要条件。它们的造型修改是否方便 ,是提高设计效率的重要途径。本文总结了工艺补充面和压料面设计中的常用方法 ,分析了常见的二维参数化建模方法 ,选择在UG软件平台下使用编程法 ,开发了基于二维截面特征库的工艺补充面和压料面参数化设计模块。

The addendum and binder surface design has great effects on the quality to auto. The modeling convenience is an access to improve design efficiency. The paper summarizes usual methods of design for addendum and binder surface, analyzes the characteristics of varied parametric modeling method, and develops a parametric design module for addendum and binder surface on UG platform.
