Document Type and Number:
Japanese Patent JP4561008
Kind Code:
B2
Abstract:
Excessive increase in processing loads and damages to a thickening roller resulting from pressing the thickening roller against the blank from the outer peripheral end face are prevented, and processing of a cylindrical member having an enlarged diameter portion is made possible. With the side surface of an intermediate portion of a blank abutting and being supported on an increased diameter portion of a mandrel, a thickening roller is pressed against the side surface of the intermediate portion and moved in the radially inward direction. The blank is thus partially thickened, and the thickened portion is pressed into tooth spaces formed in a columnar portion of the mandrel, whereby splines are formed.
