摩擦片是机床的易损件,用量很大。它的热处理工艺难度大、耗能高,而且使用寿命较低,一般在3～6年机床大修时,就须更换。因此寻求一种优质低耗的摩擦片热处理工艺,是十分重要的课题。一、传统的摩擦片热处理工艺我厂生产的机械插床摩擦片结构示意如图1和图2所示,材料为A3钢,技术要求:渗碳深度0.3～0.5mm,渗碳、淬火后硬度HRC56～62,平面度<0.08mm。其工艺流程是:下料→车削→冲凸瓣或拉
Friction plate is the wearing parts of the machine, a large amount. Its heat treatment process is difficult, high energy consumption, and lower life expectancy, usually 3 to 6 years when the machine overhaul, it must be replaced. Therefore, to seek a high quality and low friction plate heat treatment process is a very important issue. First, the traditional friction plate heat treatment process I plant the mechanical slotted friction plate structure shown in Figure 1 and Figure 2, the material is A3 steel, technical requirements: carburizing depth 0.3 ~ 0.5mm, carburizing, quenching hardness HRC56 ~ 62, flatness <0.08mm. The process is: cutting → Turning → punch flap or pull
