Claims (1)

[Scope of utility model registration request] In order to process multiple types of workpieces that can be heated under nearly identical matching conditions, the heating station is equipped with multiple heating coils of different shapes, and the heating coils are selected and used depending on the type of workpiece being fed. In the induction heating device, the matching transformer to be arranged is divided into one primary element connected to the power supply and a plurality of secondary elements, and the secondary element has the inner diameter of the wound conductor connected to the primary element. They are formed to have the same structure with the same dimensions slightly larger than the outer diameter of the wound conductor of the side elements, and the heating coils are fixed to each of the secondary side elements, so that a desired one of the secondary side elements and the primary side element are attached. The primary element and the secondary element occupying opposing positions form a transformer, and the heating coil fixed to the secondary element performs heating. An induction heating device equipped with multiple coils.
