设计简介
摘要
本文介绍了汽车中奥迪A4车顶纵梁冲压模的设计过程。分析了汽车覆盖件及其冲压模的特点及要求。对零件的CAD数学模型进行了分析，该零件数学模型为由片体构成的非参数化特征（umparameteied）。由于零件数学模型是以整个汽车为基准设计的，为了得到合格的零件产品，必须先进行拉深方向的确定，然后进行了拉深件的设计。拉深件的设计包括工艺补充、压料面，拉延筋的设计。以拉深件为基础进行了两套冲压模具的三维设计并进行了装配。由三维模具再进行模具的二维设计。最后还介绍了两种汽车覆盖件模具制造先进制造技术：实型制造与刃口堆焊技术。

This article introduced the process of stamping die design of in front of the automobile the host column strengthens . Has analyzed the the characteristic and the request of automobile cover and its stamping die. Has carried on the analysis to the components CAD mathematical model, this components mathematical model for the non-parameter characteristic which constitutes by the piece body (umparameteied). Because the components mathematical model is take the entire automobile as the datum design, in order to obtain the qualified components product, must first carry on stamping the direction determination, then has carried on stretch component a design. Stretch component a design supplemented including the craft that, presses the material surface, strecth muscle design. Has carried on for the foundation two sets of stamping die molds three dimensional designs and has carried on the assembly ,has entered the good mold two-dimensional design again by the three dimensional mold. Finally also introduced two kind of automobiles covers mold makes the advanced manufacture technology: Solid manufacture and piles weld technology.
Key word: The automobile cover, the mathematical model, the craft supplemented ,stamping die, CAD.
