摘　　要：制件在拉伸成形过程中,受压机挠度变形、材料减薄和模具结构强度不足的影响,会使拉伸制件着色差:为了提升拉伸着色,在模具结构强度足够的前提下,加工数据中可以运用压机挠度变形补偿、制件减薄补偿、设计关键型面强压、非关键型面空开的方法,可有效地提升首件着色率.During the drawing and forming process of the part, due to the press deflection deformation, material thinning and the weak die structure, the spotting of draw parts will be not good. In order to improve the spotting for draw part, on the premise of enough strength die structure, in the NC surface we can do the compensation for press deformation and material thinning, design hard pressure in the main surface and relief the other area, can effectively increase the spotting rate for first draw part.
