Problems solved by technology

In particular, such a detour type sensor has a special shape, so to use this sensor, not only it takes time to manufacture the sensor and increases the cost, but also the installation operation is not easy, and in the subsequent adjustment operation, sometimes the Man-hours such as remodeling of the trial-and-error sensor are required, which greatly increases the construction cost
[0017] In addition, in these conventional induction heating technologies, regardless of whether it is the type of feeding in the circumferential direction, the type of feeding in the axial direction, or the type in which the feeding direction is detoured from the axial direction to the When the shaft-shaped member 10 of the bar is used, there will be a problem of difficult adjustment

Abstract

The purpose of the invention is to: follow single heat mode with excellent production efficiency, and avoid the cost from rising to decrease the supply frequency so as to cause the axis-shaped component (10) changing along the diameter of axle to be able to easily adjust the heating homogenization. When executes induction heating to the axis-shaped component (10), the whole length of the heating area (17) is configured with axial direction feed inductor (21) and peripheral direction feed inductor (22) in moving heating mode; on one hand, the axis-shaped component (10) rotates around the axes, and on the other hand, the high frequency current is fed to the inductor (21), (22). Through the two systematizations of such heating device, the invention is able to execute the adjust of the axial direction feed inductor (21) with respect to the base circumferential face (11) and the adjust of the peripheral direction feed inductor (22) with respect to the raised line (12), so the excellent products are effectively produced with low cost.

Description

technical field [0001] The present invention relates to a method and an apparatus for inductively heating the surface layer portion of a shaft-shaped member having ridges on its outer peripheral surface. The shaft-shaped member of the convex line is the object of induction heating, and the inductor is placed close to the shaft-shaped member, and a high-frequency current is fed to the inductor (high-frequency energization), thereby generating an induced current in the surface layer of the shaft-shaped member , an induction heating method for a shaft-shaped member with convex strips for inductively heating the convex strips of the shaft-shaped member and the peripheral surface of the base, and an induction heating device suitable for implementing the method. Background technique [0002] Conventionally, as a technique for inductively heating the surface layer of a shaft-shaped member with protrusions, there are known a technique of feeding (energizing) in the circumferential d...
