用斜轧方法生产轴承滚子毛坯,可以代替冷镦机及大吨位冲床。此方法具有设备简单、制造容易、上马快、生产率及材料利用率高,可以实现少、无切削工艺等优点,但是轧辊的寿命低,满足不了生产要求。为此,我们厂、校协作,进行了多次试验,通过固体渗碳方法提高了斜轧轧辊寿命。现将试验研究情况作一介绍: 一、斜轧轧辊工作过程及对 轧辊提出的技术要求 Rolling method with the production of roller bearing rough, you can replace the cold heading machine and large tonnage punch. The method has the advantages of simple equipment, easy manufacture, quick start-up, high production rate and material utilization, less realization, no cutting process, etc., but the life of the roll is low and can not meet the production requirements. To this end, our factory, school collaboration, conducted a number of tests, through the solid carburizing method to improve the rolling mill life. Now the experimental research to make an introduction: First, the work process of the roll and the roll roll made of the technical requirements
