(Prior Art) An induction hardening device winds an excitation coil around a metal member to be hardened, and applies a high-frequency current to the excitation coil to cause hysteresis loss and overcurrent loss in the metal member. This is a device that heats and hardens the material. FIG. 2 is a diagram showing the principle of high-frequency induction heating, in which A is an external view and B is a cross-sectional view.
As shown in the figure, when a high-frequency coil (also called a work coil) 2 is wound around a magnetic metal body 1 and a high-frequency current is passed through it, high-frequency magnetic flux flows on the surface of the metal body 1 (wire area). Electric current due to high-frequency magnetic flux flows on the surface of the metal body, causing hysteresis loss and overcurrent loss, and heating that part.

Such an induction hardening device is mainly used to harden the rotating shaft of a car. According to induction hardening, only the surface of the metal body is hardened, and the core part does not need to be hardened at all, so it is possible to create a rotating shaft that has both hardness and tenacity. At this time, the thickness of the surface layer of the metal body subjected to induction hardening is determined by the frequency and the material of the metal body to be heated. For example, if the metal body is iron, the frequency is 400KHz near the quenching temperature (850℃).
It is about 0.8mm, 1.6mm at 100KHz, and 5mm at 10KHz. Therefore, the desired frequency is selected depending on the desired hardening depth.

(Problems to be Solved by the Invention) In the conventional device shown in FIG. 3, a high frequency current flows through the contact surface C between the member 17 and the rotating member 11. Here, the member 17 and the rotating member 11 are strongly pressed by a spring 20 attached to the fulcrum shaft 19 to improve the flow of current on the contact surface C. However, the contact surface C is the high frequency coil 1
Each time 2 and 12' open and close, they all create friction.
As a result, the contact surface becomes rough, and current flow becomes poor due to copper powder generated by wear.
The same situation applies to the contact surface between the member 17' and the rotating member 11'. If the condition of such a contact surface defect worsens further, it may become a cause of failure of the high frequency oscillator.

In addition, in order to use a high-frequency coil whose size corresponds to the outer diameter of the object to be hardened, it is necessary to use a rotating member with an inner diameter that matches the outer diameter of the high-frequency coil. It is necessary to replace the rotating member itself, which is not only troublesome, but also requires preparing a variety of rotating members, which increases costs.

According to the present invention, the high frequency current is transmitted through the adapter 33,
33' and the lead plates 35, 35' through the crimping surfaces D, D'. There is no flow through the rotating contact surface C as in the prior art device shown in FIG. Therefore, since almost no wear occurs, the condition of the crimping surface is stable, and the flow of high frequency current is not impaired. Therefore, a stable energization state can be obtained. In the case of the conventional system, if the contact between the opening and closing parts became poor, current could flow through the fulcrum. When such a current flows, the fulcrum becomes severely worn, and the coil current flows in a detour, resulting in poor efficiency. Furthermore, it is unstable from which part of the contact portion the current flows, resulting in unstable quenching. According to the present invention, such a problem does not occur.

In addition, an insulating flange with a high-frequency coil with an inner diameter that corresponds to the outer diameter of the object to be hardened (the inner diameter matches the outer diameter of the installed high-frequency coil, so it varies depending on the high-frequency coil, but the outer diameter of all It is possible to handle objects to be hardened with various outer diameters by simply replacing the same one), and there is no need to replace the rotating member. Therefore, not only is the replacement work easy, but the cost can also be reduced.

(Effects of the invention) As explained in detail above, according to the invention,
The high frequency current is crimped between the lead plate and the adapter part without passing through the contact part where rotational friction occurs.
Since it is configured to pass through this crimped portion, stable current supply can be performed with almost no wear on the contact portion. Furthermore, by replacing the insulating flange, it is possible to accommodate objects to be hardened with various outer diameters, making the replacement work easier and reducing costs.
