- 通过圆筒形及盒形件拉深前后网格变化分析，并确定变形区和非变形区，由此得到不规则盒形件毛坯展开形状由不变形区和参与变形拉深线组成，并用此方法计算出汽车制动阀安装板的毛坯形状和尺寸，在试模时一次即获得成功，具有一定的实用价值。
In this paper,through stress analysis of region about conical and spherical parts during drawing,a calculating formula of maximum tangential compressive stess in unsupported wall region is deduced.And this is condition of causing internal wrinkle.Then on the premise to guarantee not breaking workpiece,a critical calculating formula is presented.
