摘　　要：在进行大型汽车覆盖件的冲压工艺设计时,通常冲压工艺设计的拉伸工艺方案是把压料面选取在制件的一侧,模具结构采用单压边圈的形式。对于一些特殊形状的制件,如果把压料面选取在制件的中部位置,采用上、下双压边圈的模具结构,能够有效的降低拉伸深度、更有利于制件的成形、并且能够有效提高材料的利用率。In the stamping process design of large automobile panel, the drawing addendum of stamping process design is to select the biner surface on one side of the product, and the die structure is in the form of single binder. For some products with special shapes, if the binder surface is selected at the middle position of the product and the die structure use the upper and lower binder is adopted, the drawing depth can be effectively reduced, the forming feasibility of the product is more favorable, and the material utilization can be effectively improved.
