Abstract

See full text

A nut integrated with a bracket and a method of manufacturing the same is provided. The method includes a pre-drawing operation that forms a reference aperture and a processing cross section in the plate material supplied between the punch and the die, forming a beading portion and piercing a center of the beading portion. A forging operation forms a pipe portion having a tube shape and processes an exterior circumferential surface of the pipe portion. A precision forging process adjusts dimensions of the pipe portion formed in the tube shape, forms a protruding end that extends on a tip surface of the pipe portion and compresses the pipe portion to remove residual burrs on a surface. A post-processing operation cuts the processing cross section to a final product shape, and forms a threaded tap on an interior circumferential surface of the pipe portion.
