Problems solved by technology

[0007] However, when the induction heating object is rotated, if the timing of changing the power supply amount deviates, the quenching of the induction heating portion will become uneven.
In addition, if the required power is not supplied for some reason, the induction heating of the induction heating object will be insufficient

Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0027] Such as Figure 4 As shown, the induction heating device 1 has a power supply device 2, a heating coil body 3, a heating coil body moving device 4, a rotation angle detection sensor 7 (rotation angle detection mechanism), and a control device 8 (power detection mechanism). Next, each configuration will be described.

[0028] First, the heating coil body 3 will be described.

[0029] Such as figure 1 , figure 2 As shown, the heating coil body 3 has a conductor 15 formed of a material having both conductivity and durability. Part of the conductor 15 constitutes a heating coil portion 16 that can be arranged oppositely along the peripheral surface of the crankshaft 5 (object to be heated by induction) along the peripheral surface of the crankshaft 5 (object to be heated by induction). The heating coil unit 16 is configured by bending and bending a part of the ...

Abstract

The invention relates to a method and device for monitoring the supply power of an induction heating device, wherein the supply power corresponding to a rotation angle position of an inducted heating object is monitored when the induced heating object is inductively heated. When performing high frequency inducted heating on a rotating inducted heating object, a conductor opposite to an inducted heating part of the inducted heating object is shifted opposite to the whole circumference of the inducted heating part; the power is supplied to the conductor so that the hardening depth of the circumference of the inducted heating part becomes uniform; and the supply power corresponding to the rotation angle position of the inducted heating object can be detected.

Description

technical field [0001] The present invention relates to a method of monitoring power supply and a device for monitoring power supply when an object to be heated is inductively heated by an induction heating device. Background technique [0002] Conventionally, the cam portion of the camshaft, the connecting rod neck of the crankshaft, etc. have been quenched to obtain the required hardness and wear resistance. In particular, quenching by high-frequency induction heating generates a high-frequency induction current on the surface of the induction-heated object, so that the surface temperature of the induction-heated object rises to the temperature required for quenching. Since no pollutants are discharged, it is beneficial Environmental friendly. [0003] High-frequency induction heating is a quenching method, that is, a high-frequency current flows through a conductive conductor, and the high-frequency current is used to generate a high-frequency induction current on the su...
