保证汽车覆盖件具有优良拉深工艺的方法

汽车覆盖件的工艺性关键是拉深工艺性,车身表面质量的好坏也取决于覆盖件拉深的结果,必须认真分析覆盖件的拉深工艺。采用案例分析法,从汽车覆盖件材料的合理选用、冲压工序的合理安排、拉深冲压方向和压料面的正确确定、反拉深成形的合理安排、拉深工艺补充部分、工艺冲孔或切口的合理确定以及拉深筋的合理设置7个方面,对汽车覆盖件的拉深工艺进行了分析。通过这些工艺的合理安排与确定,可有效地抑制汽车覆盖件拉深过程中起皱和裂纹的产生,提高拉深稳定性,保证汽车覆盖件具有良好的拉深工艺。

Ways to ensure successful drawing process for automobile panel

The key process of automobile panels is deep drawing and the surface quality also depends on the drawing results. Hence, carefully analysis on the deep drawing process of panels is necessary. By case analysis, panel drawing process was analyzed in seven aspects, reasonable selection of material, proper arrangement of stamping, correctly choice of the drawing direction and binder face, proper arrangement of anti-drawing, complementary part for the drawing process, rational punching and cutting and advisable set of drawbead. Through the reasonable arrangement and determination of the process, wrinkles and cracks in drawing process were effectively inhibit. Also, drawing stability was improved and the car panel drawing process is ensured to be good.
