DEVICE FOR SUPPORTING HEATED PRODUCT

PROBLEM TO BE SOLVED: To provide a device for supporting a heated product capable of selectively induction heating both an outer circumferential surface and an inner circumferential surface of the heated product and that can be employed also for a large-sized heated product.SOLUTION: Motion members 70 for supporting heated products 2 are arranged on supporting tables 12 installed at a plurality of locations. They are connected to a disc member 16 through link members 13, 14. The disc member 16 is provided with longitudinal holes 57 and the link member 14 is provided with a pin 102. The pin 102 passes through the inside of the longitudinal hole 57 and the pin 102 can be reciprocated along the longitudinal hole 57. The longitudinal hole 57 is inclined in respect to a straight line connecting a center 16a of the disc member 16 with the supporting table 12. When the disc member 16 is rotated, the pin 102 is pushed by the inner wall of the longitudinal hole 57 and linearly moves in a radial direction of the disc member 16 and the motion members 70 follow the expansion of the heated product 2 while pushing and supporting the heated product 2. 【課題】被加熱物の外周面と内周面を選択的に誘導加熱することができるように被加熱物を支持することができ、大型の被加熱物にも採用することができる被加熱物の支持装置を提供することである。【解決手段】複数箇所に配置された支持台１２上に、被加熱物２を支持する移動部材７０を配置する。リンク部材１３、１４を介して円板部材１６と接続されている。円板部材１６には、長孔５７が設けてあり、リンク部材１４にはピン１０２が設けてある。ピン１０２が長孔５７内を挿通しており、ピン１０２は長孔５７に沿って往復移動可能である。長孔５７は、円板部材１６の中心１６ａと支持台１２とを結ぶ直線に対して傾斜しており、円板部材１６が回転すると、ピン１０２は長孔５７の内壁に押圧されて円板部材１６の半径方向に直線移動し、移動部材７０は、被加熱物２を押圧支持しながら被加熱物２の膨張に追従する。【選択図】図１３
