1. electric heating device will be hot pressed into the workpiece of shape and apply the tractive force heating of switching on one side it clamps by clamp mechanism on one side, and this electric heating device is characterised in that,Described clamp mechanism has:

  • Fix to clamp parts, the side that it can clamp a side of described workpiece and keep this workpiece, and along the position of predetermined direction be fix or can carry out fixed-site along predetermined direction;

    AndMovable clamping part, the opposite side that it can clamp the opposite side of described workpiece and keep this workpiece, and can move along predetermined direction;

    When switching on heating, describedly fix to clamp parts keep described workpiece in the fixed position a side, described movable clamping part thus to this workpiece applies traction force along with the thermal deformation along described predetermined direction of described workpiece keeps opposite side one edge of this workpiece predetermined direction to move on one side.
