摘　　要：拉延是利用拉深模使平面板料变为开口空心件的冲压工序。作为典型汽车覆盖件冲压工艺的首道工序,拉延工艺的优劣将直接对汽车覆盖件外观质量以及后续的工艺设计产生影响。文章以典型钢板汽车覆盖件为研究对象,结合实际生产经验,从常用板料、冲压方向、工艺补充注意点、拉延筋四个方面详细介绍了拉延工艺设计要点,分析了拉延工序中常见质量缺陷及避免方法,对典型钢板汽车覆盖件同步工程分析、模具设计及调试等具有一定的参考价值。Drawing is the process of making the flat plate into open hollow part by drawing die. As the first process of typical automobile panel stamping process, drawing process will directly affect the appearance quality of automobile panel and subsequent process design. Based on the typical steel automotive covering parts as the research object, combined with the actual production experience, from common sheet metal, pressing direction, addendum attention points, drawbead drawing process design points are introduced in detail, analyses the drawing working procedure in addendum attention points of common quality defects and avoid method, the typical steel automotive covering parts synchronous engineering analysis, mold design and debug and so on has certain reference value.
