热处理是机床制造中不可缺少的组成部分,它对于提高产品质量及使用寿命等起着重要的作用。几年来,我厂重视热处理车间的建设,使热处理工作逐渐适应形势发展的要求。过去我厂热处理设备很简陋。现有的设备多数是这几年发展起来的,包括中温箱式电炉、中温井式电炉、回火井式炉、中温盐溶炉、高频机、硬度计、磁力探伤机等,还有自行设计制造的使高频淬火半自动化的液压式淬火机。热处理工艺及操作方法也是工人长期以来从实践中摸索出来的经验总结。现将我厂过去主要的成批生产产品 C615普通车床的几个主要零件的热处理情况介绍如下:
Heat treatment is an indispensable part of machine tool manufacturing, which plays an important role in improving product quality and service life. Over the past few years, I plant emphasis on heat treatment plant construction, so that heat treatment gradually adapt to the development of the situation. In the past I plant heat treatment equipment is very simple. Most of the existing equipment developed in recent years, including the temperature box-type electric furnace, electric furnace in the pit, tempered pit furnace, temperature salt furnace, high frequency machine, hardness tester, magnetic detection machine, as well as their own Design and manufacture of high-frequency quenching semi-automatic hydraulic quenching machine. Heat treatment process and method of operation is also workers experience has been groping for a long time from the experience summed up. Now I plant the main mass production of products in the past C615 ordinary lathe heat treatment of several major parts are described below:
