Abstract

PURPOSE: To easily perform swaging on a spindle blade made of a material which is hardly affected from plastic deformation, by dividing the upsetting process by swaging into a manufacturing process of a standard spindle blade and a bobbin fitting taper part which fits to the top hole of the bobbin to be used.
CONSTITUTION: In the first process, a rough forging is performed to make a tapered part which make upset to a intermediate bearing part 28 of small diameter section from a large diameter section 21, and, in the second process, a bearing supporting section 22 of a prescribed dimension is formed on a roughly forged crude material A. In the third process, a bobbin holding secton 28 of the upper part of a blade is formed, and a finish forging is performed on a bobbin fitting part 27 to be fitted to the top hole of the bobbin in the fourth process. Then, centers C1 and C2 of a necessary angle is formed at both ends by a centering machine and thus blade formed products 2 are obtained.
