摘　　要：用盒形件拉伸成形工艺参数判断油底壳的拉伸成形时,油底壳需要2道拉伸工序成形,拉伸模具增加拉伸筋后,可使油底壳1道工序拉伸成形,并介绍了几种拉伸筋的结构、形状及布置注意事项。When the technological parameters for drawing the box-shaped parts are used to judge the drawing number for the oil container bottom shell,it turned out that two-time drawing is needed for forming the oil container bottom shell.But with a drawing rib added to the drawing die,the oil container bottom shell can be formed by one-time drawing.The structures and shapes of several kinds of drawing ribs and the items needing attention in arrangement of the drawing ribs are introˉduced.
