本文介绍了针对国内汽车半轴行业采用半机械化手工操作生产的半轴质量的不稳定状态,通过引进、消化、吸收,研制了采用pc 机控制的汽车半轴中频淬火工艺及其应用情况.本工艺的控制,使半轴从快退转工退后圆盘定位精度达±0.25mm,半轴加热后从小喷水转大喷水的位置及喷水量直到停止喷水的控制十分准确,其精度达±0.1秒,按半轴各段要求,从工进Ⅶ=7～8mm/S 到工进Ⅵ=4～5mm/S 自动变速,实现了机械化自动化.最终使半轴硬层深度达到±0.2mm,表层硬度达到±3HRC.从而使产品各项性能达到国内先进技术经济指标,产品质量达到国家优等品水平.
This paper introduces the semi-axle industry for the domestic semi-axle manual production of semi-shaft quality of the unstable state, through the introduction, digestion and absorption, developed by pc-controlled car semi-shaft IF quenching process and its application. Process control, so that the half-axle retreat after retreating Disc positioning accuracy of ± 0.25mm, after the half-shaft heating from a small jet to a large jet position and water spray until the stop spraying control is very accurate, the Accuracy of ± 0.1 seconds, according to the requirements of the various sections of the semi-shaft, from the work of VII = 7 ~ 8mm / S to work Ⅵ = 4 ~ 5mm / S automatic transmission to achieve mechanization and automation. 0.2mm, the surface hardness of ± 3HRC. So that the performance of various products to achieve domestic advanced technical and economic indicators, product quality to achieve the national level of quality products.
