一、前言我厂新产品2V3.5-20/8无油机活塞杆(见图1),采用3Cr13不锈钢进行高频表面淬火处理,要求硬度为HRC50～58。在试制中,使用老产品2Z-6/8-1型无油机活塞杆高频淬火工艺达不到技术要求,外协和加工的质量又不可靠。为在厂内解决该零件高频表面淬火质量问题,对活塞杆高频淬火工艺进行了研究。我厂在所掌握的资料基础上,经过分析
I. Introduction Our new product 2V3.5-20 / 8 oil-free piston rod (see Figure 1), the use of 3Cr13 stainless steel for high-frequency surface hardening, hardness of HRC50 ~ 58 required. In the trial production, the use of old products 2Z-6 / 8-1 oil-free piston rod high-frequency quenching technology failed to meet the technical requirements, the quality of the Association and the processing is not reliable. In order to solve the high-frequency surface hardening quality problem of this part in the factory, the high-frequency quenching process of piston rod was studied. I plant in the grasp of the basis of information, after analysis
