一、前言近年来,锻压技术有了很大的发展,以轧代锻,少无切削成型新工艺迅速发展,其中用螺旋孔型斜轧成型工艺,代替传统的锻压工艺,生产某些回转体短轴类零件(一般长度小于130mm)或零件毛坯以及用楔型横轧工艺,代替锻压工艺生产某些斜轧成型不易完成的较长轴类零件或零件毛坯(目前国内最长件长度达2 m),都具有单机生产率高,节省原材料,改善工人劳动条件等一系列明显的特点,目前在各行业中得到了比较广泛的应用。
I. Introduction In recent years, great progress has been made in forging technology, with the rapid development of rolling forging and less non-cutting forming new technology, which uses spiral hole type of cross-rolling forming process instead of the traditional forging process to produce certain rotary bodies Short-axis parts (usually less than 130mm in length) or rough parts and the use of wedge-type cross-rolling process, instead of forging production of some difficult to complete cross-rolling forming a long shaft parts or parts rough (currently the longest length of 2 m) have a series of obvious features such as high productivity of single machine, saving of raw materials and improvement of working conditions of workers. At present, it has been widely used in various industries.
