我厂用感应器上涂搪瓷的方法进行小模数齿轮的单齿加热,由于工件与感应器之间的间隙小,齿轮的根部及齿尖加热都很均匀,感应器与工件在加热时互碰也不打火,操作十分方便,保险,解决了生产中的一个难题。搪瓷材料虽易买到,但要求搪瓷粉的膨胀系数与紫铜管的膨胀系数大致相同,并能绝缘。搪瓷粉有底粉和面粉两种,用时将底粉和面粉分别加水,先后调涂。涂搪瓷的方法是:1.涂前的感应器须经去油(或在炉内烧一下)、酸洗、清洗,使表面洁净。
I plant with the sensor coated enamel method for small modulus gear single tooth heating, due to the gap between the workpiece and the sensor, the gear root and tooth tip heating are uniform, the sensor and the workpiece in the heating each other No touch hit, the operation is very convenient, insurance, to solve a problem in production. Although easy to buy enamel material, but required expansion coefficient of enamel powder and copper tube expansion coefficient is about the same, and can be insulated. Enamel powder and flour at the end of the two, when the end of the flour and flour were added water, has Tu Tu. The method of enamel coating is: 1. Before coating the sensor to be degreased (or burning in the furnace), pickling, cleaning, the surface clean.
