Abstract

PURPOSE: To shorten a manufacturing process of buckle and to improve its finishing, by bending both end sides of a piece of raw material after punching for a suitable form from a metallic sheet and deforming it plastically by pressing.
CONSTITUTION: A piece of U-shaped raw material 21 is formed by punching a mettalic sheet 20 along the chained line drawn on it and fitting holes 22 for fitting pins are formed at both ends of a piece of raw material 21. Both side frames 23 are bent vertically in the same direction along each chained line to make it parallel to each other. Then, the tips 24 of both side frames 23 of the material 21 are forcibly pressed to deform plastically with least unevenness at their surfaces and all edge parts etc. are finished so that the frame body 26 having a connecting frame 25 formed in one body at their tips 24 of both the side frames 23 can be manufactured.
