摘　　要：拉深模具模面设计是决定复杂车身覆盖件成形成败和成形质量的关键环节。针对拉深模面设计主要依靠定性分析和经验数据的问题,提出了一种覆盖件模面设计方法。用特征图法确定冲压方向,研究了压料面张角、工艺补充部分、拉延筋布置形式对拉深质量的影响,并通过有限元模拟验证了模面设计的有效性。The design of drawing die face is a key link to decide success or failure and the forming quality of automobile panel. Aiming at the problems of which the drawing die face design relieD mainly on qualitative analysis and experience data, a new method of the die face of automobile panel design was proposed. The stamping direction was determined by using characteristic diagram method. The effect of the binder opening angle, the addendum and the drawbead layout form on the drawing quality was studied. The validity of the design of die face was verified through the finite element simulation.
