Abstract
A conduction heating apparatus performs conduction heating while clamping a work to be hot press-formed by a clamping mechanism to apply tension to the work. The clamping mechanism has a stationary clamping member and a movable clamping member, a lifting up/down cylinder for the stationary clamping member and the movable clamping member, and tensioning cylinders that drive the movable clamping member along the planar direction of the work, and in conduction heating. The stationary clamping member clamps one side of the work and hold it, and the movable clamping member moves while holding the other side of the work according to thermal deformation of the work, which applies tension to the work corresponding to the thermal deformation of the work.
