Claims

[Scope of utility model registration request]

One of the multiple heating coils that differ depending on the type of workpiece is connected to a common current transformer for these heating coils, so that each hardening machine can perform induction hardening of multiple types of workpieces. A plurality of hardening machines installed, a high-frequency oscillator that selectively supplies high-frequency current to these hardening machines, a control device that controls the high-frequency oscillators, and a The control device is an induction hardening equipment system which has a work type display device installed at a location, and a control device which instructs a high frequency oscillator about the hardening machine to be energized and the input conditions to the hardening machine. The heating coil has 1 to n switch operating pieces positioned according to the type of the heating coil,
The current transformer includes n switches corresponding to each of the n switch actuation pieces,
In addition, when the heating coil is connected to the connection terminal of the current transformer, the control device receives the signal from the switch activated by the 1 to n switch operation pieces, determines the type of the heating coil, and activates the heating coil. An induction hardening apparatus system characterized in that the type of the corresponding workpiece, etc. is displayed on the workpiece type display device.
