我厂为了解决小型螺旋弹簧的热处理关键,组成了三结合小组,自行设计制造了一合小型螺旋弹簧保护气体淬火炉,经三年多的生产实践考核,性能稳定,效果良好,基本上解决了原来弹簧淬火质量不合格的关键,现介绍如下,供大家参考。一、结构螺旋弹簧保护气体淬火炉的结构示意图见图1。它由装料、炉体及加热、冷却和滴油保护装置等部分组成。二、操作首先升温到工作温度,这时柄式淬火斗3的温度当然也升到了工作温度,拉出淬火斗,使斗口对准炉门口,然后将水平炉门盖2打开,弹簧工则自动掉入淬火斗内,这时推动手柄淬
I plant in order to solve the small coil heat treatment of the key to the formation of a three-in-a-small group to design and manufacture of a combination of small helical spring protection gas quenching furnace, after more than three years of production practice assessment, stable performance, good effect, basically solved The original spring quenching the key to the quality of failure, are presented below, for your reference. First, the structure Helical spring protection gas quenching furnace structure diagram shown in Figure 1. It consists of loading, furnace and heating, cooling and drip protection devices and other components. Second, the operation was first warmed to the operating temperature, then the handle quenching bucket 3 of course, the temperature rose to the working temperature, pull out the quenching bucket, the bucket mouth at the furnace door, and then open the level of the furnace door 2, spring work Quench automatically fall into the bucket, then promote the handle quenching
