球形零件感应加热表面淬火是比较困难的,有人曾设计了各种各样的仿形同时加热感应器,但往往由于淬硬层分布不均匀而不得不采用盐炉整体加热淬火,代替感应加热表面淬火。笔者结合本厂引进产品,设计了一种球头销加热感应器,解决了球形零件感应加热表面淬火的难题。球头销材料为42CrMo钢,基体经预先调质处理,形状如图1所示。要求φ130球 Induction heating of spherical parts surface hardening is more difficult, and some people have designed a variety of shapes at the same time heating sensors, but often due to uneven distribution of hardened layer had to use the overall heating furnace quenching, instead of induction heating the surface Quenching. The author combined the introduction of the factory products, designed a ball pin heating sensor to solve the problem of spherical parts induction heating surface hardening. Ball head pin material 42CrMo steel, the substrate by pre-quenched, the shape shown in Figure 1. Requires φ130 ball
