为了防止零件表面尖角部位在感应淬火过程中发生开裂,设计了一种装置,可以将零件表面尖角部位完全遮盖。该装置同时可以避免因感应器与零件接触而造成短路,从而避免零件被电流击伤。结果表明:使用该防开裂装置及方法,不仅可以有效避免零件表面尖角部位在感应淬火过程中发生开裂,而且可以避免零件被电流击伤。 In order to prevent parts of the sharp corner of the surface during induction hardening cracking occurred, the design of a device that can be part of the sharp corners of the surface completely covered. The device at the same time to avoid contact with the sensor and the resulting short circuit, so as to avoid parts being current injury. The results show that the use of the anti-cracking device and method not only can effectively prevent cracking of parts with sharp corners during induction hardening, but also can avoid parts being damaged by current.
