摘要
对宽凸缘工件首次拉深最大相对高度表中(dt/d1)的排序作了修正,并对最大相对高度(h1/d1)和极限拉深系数m1这两种极限变形程度的实验数据的相容性进行了推算与验证。结果表明二者有较好的一致性。
The order of ratio ( dt/d1 ) in table for maximum of highness-diameter ( h1/d1 ) in first drawing process is revised. The compatibility between maximum of ratio ( h1/d1 ) and minimum of drawing coefficient m1 is verified.
