Abstract
PURPOSE: To reduce the thermal deformation caused by welding by the process that a sheet of a rectangular plate is pressed to make an upper vane and a lower vane and the front edge is bent to be welded on the rear edge.
CONSTITUTION: The cold press is applied to bend a rectangular steel plate 6 to make an upper vane and a lower vane, with an upper mold 7 and a lower mold 8 catching the plate. The front edge 4 is shaped flat. The front edge 4 is put between the extra bending upper mold 7a and the lower mold 8a and is bent to fold by applying the partial hot press. With a fish-shaped mold 9 put in the steel plate 7, the upper mold 7b and the lower mold 8b press the plate and the front edge 4 is welded.
