在机器制造中,少不了各种形状的罩壳(如床头罩壳、皮带轮罩壳、防水防尘罩壳等)。这些罩壳都是板金件居多,虽然形状各异,但是做成圆角的不少。特别是在交角处呈球形,其大小正好是球面的1/8瓣。 在板金件加工过程中,这个1/8球形圆角是冲制成形后焊补上去的,一般称为“球形补角” In the manufacture of machines, and ultimately the shape of the cover (such as bed cover, pulley cover, waterproof dust cover, etc.). These shells are the majority of sheet metal pieces, although different shapes, but made a lot of rounded corners. Especially in the corner of spherical, its size is exactly 1/8 petal spherical. In the sheet metal processing, the 1/8 spherical fillet is welded up after forming, commonly known as “spherical complement”
