万向节叉冲压工艺及其成形过程

Stamping Process and Forming Process for the Universal Joint Fork

该万向节叉成形是由落料、冲孔、切斜面(一模两件)、弯曲、压弯、压合、压弧、压弯、成形九道冲压工序;再经过机加与表面处理共十一道工序来完成整个制件。此制件是通过精确计算和分解成多道工序而完成的。

The universal joint fork forming is by punching, punching, sharping （exactly two）, bending, bending, pressing, pressure arc, bending and forming nine channel stamping process; Then after machine add and surface treatment were eleven procedure to complete the whole product. This product is through the precise calculation and broken down into many processes and finished.
