Abstract

An energization heating device which can feed an energization heated work stably to the process downstream the energization heating while preventing distortion of the work by energization heating as much as possible. A hot press forming device having it and a energization heating method are also provided. In the energization heating device (3) for energization heating a work to be hot press formed (W) while clamping by a clamp mechanism (30, 31, etc.) and applying tension, the clamp mechanism (30, 31, etc.) comprises a fixed clamp member (30) and a movable clamp member (31), an elevating/lowering cylinder (32) for the fixed clamp member (30) and the movable clamp member (31), and tensioning cylinders (33a, 33b) for driving the movable clamp member (31) along the plane direction of the work (W). During energization heating, the fixed clamp member (30) holds the work (W) while clamping the one side thereof at a fixed position, and the movable clamp member (31) moves while holding the other side of the work (W) as the work (W) deforms thermally, thus applying tension to the work (W) depending on thermal deformation of the work (W).
