  • Patent Document 1 The disclosure in Patent Document 1 described above is herein incorporated by reference. The analysis set forth below is given by the present invention. According to the conduction heating mechanism of Patent Document 1, there is a problem that the work is greatly distorted and the central portion of the work droops down regardless of an application of pulling force to a work during conduction heating.
  • the reason for the problem is that a clamping distance between the pair of right and left clamps is fixed regardless of the fact that a work expands according to a temperature rise during conduction heating. That is, since the both ends of the work are restrained at the fixed positions in conduction heating, as a result, the central portion of the work easy to be thermally deformed due to a temperature rise droops down by its own weight.

According to this aspect, clamping of the work is made stable, and it is easy to secure a moving stroke of the movable clamping member.
  • the lower clamps spaced from each other along the predetermined direction or the longitudinal direction of the work between the pairs of upper and lower clamps which the stationary clamping member and the movable clamping member respectively have are a pair of electrodes for energizing the work.
