叉体类锻件的锻造工艺与它的几何形状,特别是叉口尺寸有很大的关系。我厂有两种叉子锻件,其叉脚长度和叉口间距的比值较大,H/B>2。通常操作时都以横劈为主,采用前端突出的劈刀垂直叉口方向劈下,然后翻转90°合拢劈口,再从反面劈开叉口,或冲孔、切割分开;拔叉脚弯曲成型。这样,在叉口的底 Fork fork forgings forging process and its geometry, especially fork size has a great relationship. I plant two fork forgings, the fork length and the ratio of fork spacing, H / B> 2. Usually operate with a horizontal split, the use of the front end of the chopper perpendicular to the splitting direction split, and then flip 90 ° fold split mouth, and then split from the opposite side of the fork, or punching, cutting separate; forming. This way, at the bottom of the fork
