Abstract
A heating device 10 for laminated iron core has a laminated iron core 18 as an object to be processed, and performs a heat treatment on an adhesive agent applied to the iron core 18. The device 10 includes a center guide 24, and the center guide 24 is an outer diameter variable chuck mechanism of which an outer diameter is variable.
Claims7
A heating device for laminated iron core that takes a laminated iron core as an object to be processed, and that performs a heat treatment on an adhesive agent applied to the iron core, the device comprising:
- a base plate;
- a lower plate placed on the base plate;
- an upper plate placed on the iron core placed on the lower plate;
- a top plate placed on the upper plate, the base plate and the top plate being made of stainless steel not allowing a magnetic flux to easily pass through, and the lower plate and the upper plate being made of carbon steel passing the magnetic flux;
- an induction heating coil surrounding the iron core;
- a tubular ferrite surrounding the induction heating coil;
- a lower ferrite extending from a lower end of the tubular ferrite to the lower plate;
- an upper ferrite extending from an upper end of the tubular ferrite to the upper plate;
- and
- a center guide inserted into a center hole provided in the iron core,
- wherein the center guide is an outer diameter variable chuck mechanism of which an outer diameter is variable,
- the outer diameter variable chuck mechanism includes an air cylinder, a slider moved by the air cylinder, a rail that guides the slider, and a movable claw attached to the slider, and
- the air cylinder, the slider, and the rail are disposed outside a region sandwiched between the base plate and the top plate.
