Abstract

PURPOSE: To eliminate discard materials completely and improve the quality, by welding the both ends of strip metal material to form into a circular ring, and deforming it by pressure in the axial direction of cylinder to obtain a desired sectional form.
CONSTITUTION: A strip sheet 1 of material (SUS301, 304 etc.) for forming wheel rings is taken from a proper sheet material without producing any discard material. The both end parts 2,2' of this material 1 are completerly welded by plasma welding 3, and a ring form 10 of specified diameter is obtained. One peripheral edge part of this material 10 is successively expanded in the radial direction in the sectional form indicated by each stage A to E. The rolling die in each stage is a vertical rotating body corresponding to the contour of the inside and outside of each sectional form, and is designed so that the rolling and bending stress may be properly propagated. Therefore, therer is no fear of crack occurring in the peripheral edge parts 11 to 15. Further, bending parts 16, 17 are formed in this inner peripheral edge part and the other outer peripheral edge part without causing folds by pressure- drawing.
