北京钢铁学院与第二汽车制造厂在我国首先开展楔横轧生产汽车轴类零件毛坯的研究。为此选择了东风5t车上的变速箱中间轴、转向蜗杆轴,转向直接杆、转向球销及同步器锁销这5个有代表性的零件,作为研究对象。在北京钢铁学院实验轧机试轧成功的基础上,分别在二汽厂的锻造分厂及标准件分厂建立了直径为1000mm、630mm、350mm3条楔横轧生产线,现均已投入工业生产,并收到显著的技术经济效果。
Beijing Iron and Steel Institute and the second car factory in China to carry out the first cross-rolling production of automotive shaft parts rough research. To this end, we chose the five representative parts of the gearbox countershaft, steering worm shaft, steering rod, steering ball pin and synchronizer lock pin on the Dongfeng 5t car as the research object. On the basis of the successful trial rolling of Beijing University of Iron and Steel Co., Ltd., the cross-rolling production lines with diameter of 1000mm, 630mm and 350mm have been put into forging branch and standard parts branch of No.2 steam plant respectively and are now put into industrial production Received significant technical and economic results.
