自由锻造生产中,常常会遇到各种各样的分叉锻件。它们外形复杂,工艺变化繁多,尤其是对叉枝较长的立体分叉锻件则更为困难。分叉锻造是在长期实践中,并参考了“自由锻造技术”的手稿,通过整理,分门别类的加以归纳,并结合操作中的要领、胎具等予以重点介绍,以便大家互相交流学习,共同提高。当然,分又锻造工艺也有它的局限性,即在控制金属材料的体积时,特别是分叉过程中,难以测量,只能凭目测而定位,故需要一定的工作经验。其次为了达到精确地分 Free forging production, often encounter a wide range of forgings. They are complex in shape, vary in process, and are more difficult, especially for longer forks. Forging in the long-term practice, and with reference to the “free forging technology” manuscripts, through sorting, classification to be summed up, combined with the essentials of operation, such as tires to be highlighted, so that we exchange and learn together to jointly improve . Of course, sub-forging process also has its limitations, that is, in the control of the volume of metal materials, especially in the bifurcation process, difficult to measure, only by visual and positioning, it requires some work experience. Second, in order to achieve accurate points
