苏联自七十年代初起,便对以管坯为原料、用回转滚辗生产机器零件的新方法进行了研究。尤其柯拉玛道尔斯克工学院,对这种新方法的工艺过程、模具、设备、加工过程力能参数等方面的研究取得了不少成果,收到较大的经济效益。所谓回转滚辗工艺,就是用带有特殊的与零件所要求形状外形相适应的摩擦辊子对管坯进行局部 Since the early 1970s, the Soviet Union has studied the new method of producing machine parts using a rotary billet from a raw material billet. In particular, Korama Dorsk Institute of Technology has made a lot of achievements in the research on the process, mold, equipment, process energy parameters of this new method, and received great economic benefits. The so-called rotary roller rolling process, that is, with a special shape with the shape of the parts required to adapt the shape of the roller on the tube partially
