有些淬火工件上面有很多孔,如果不把这些堵住,将会影响淬火的质量。一般堵孔的方法,都是用石棉绳或者耐火材料往孔里堵塞,比较麻烦。我们最近在进行大批生产的时候,工人运天洪采用螺丝堵工件丝孔,大大地节省了辅助时间。这种办法就是:对不透的丝孔,用一根比工件丝孔稍短一些(约2～3公厘)的螺丝来堵住;在堵的时候,在丝孔底部先放一些石棉绳,在螺丝细部也缠 Some quenching the workpiece above a lot of holes, if you do not block these, will affect the quality of quenching. The general method of blocking holes, are asbestos rope or refractory material to plug the hole, more trouble. When we recently carried out large-scale production, the worker Yun-hong Hung used a screw to plug the workpiece wire hole, which greatly saved the auxiliary time. This approach is: impermeable silk hole, with a slightly shorter than the workpiece wire hole (about 2 to 3 mm) of the screw to block; in the block when the first hole at the bottom of some asbestos rope It is also wrapped in screw detail
