由于民品开发,我厂试制日本某汽车公司的汽车前桥,其中有一零件前轮毂盖(图1)。该零件属引伸件,但在圆壁上需要有一个平整的φ70台肩,该台肩较难成形。
As a result of the development of civilian products, I plant a Japanese car company car front axle, which has a part of the front hub cover (Figure 1). The part is an extension but requires a flat φ70 shoulder on the circular wall that is harder to form.
