我厂生产的电工机械设备,新产品多,热处理条件差,在单件和小批生产中,经常遇到各种工件的淬火变形问题。通过实践,找出了工件淬火变形的原因,改进了一些矫直的方法。包括:趁热矫直、锤击矫直、热点矫直、回火矫直、冷矫直等十余种,可以根据工件形状选择。现将工件淬火变形的原因和几种主要的矫直方法介绍如下:
I plant the electrical machinery and equipment, new products, heat treatment conditions are poor, in a single and small batch production, often encountered a variety of workpiece quenching deformation. Through practice, find out the cause of the workpiece quench deformation, improved some straightening method. Including: hot straightening, hammer straightening, hot straightening, tempering straightening, cold straightening more than 10 species, according to the shape of the workpiece to choose from. Now the cause of the workpiece quenching deformation and several major straightening methods are described below:
