Abstract
PURPOSE: To enable the R forming of a radiation plate of a oil filled electrical machine without to damage the close adhesion between the curved portion of the side wall and the trough portion of radiation plate, and facilitate the transporting operation and the like by a method wherein the partially curved parts are prepared at both upper and lower end of the trough portion of the wave formed radiation plate corresponding to each curved portion R of the side wall.
CONSTITUTION: A circular tank is constructed with an upper flange 13, a lower bottom plate 14 and a radiation plate 11 which is made with a steel sheet formed in the consecutive wave form. Every one pitch wave form of the radiation plate is transfered horizontally on the feed roller 9, and a trough part 2 of the radiation plate 11 is stopped on a lower mold 10a of an R forming machine 10. Lowering a upper mold 10b, the upper and lower end 12a, 12b of the trough part 12 are partially pressed against the lower mold 10a to put into practice the R forming, and flatten the center part 12c. Thus after the R forming is performed, all over the radiation plate 11 is kept in straight with no bend at the trough part 12, and R forming operation is practised without to damage the close adhesion between the curved portion of the side wall and the trough part of radiation plate 12, and facilitate the transporting operation and the like.
