MANUFACTURING METHOD FOR EYE-FORMING OF PIPE STABILIZER BAR USING MULTISTAGE UPSETTING

摘要

The present invention relates to a method for manufacturing a stabilizer bar eye part using a multi forging process. The purpose of the present invention is to provide a method for manufacturing a stabilizer bar eye part using a multi forging process processing an eye part on both end parts of a pipe material through the multi forging process and making the eye part processed on both end parts of the pipe material to have the same strength and structure as the eye part manufactured of a solid material. To achieve this purpose according to the present invention, the method for manufacturing a stabilizer bar eye part using a multi forging process includes: a first step (S110) processing the end part to have a solid structure by forging the end part of the pipe material in the axial direction so as to increase the thickness and expand the outer diameter of the end part of the pipe material; a step (S120) of processing the end part of the forging process part formed through the S110 step to correspond to the shape of the eye part; and a step (S130) of processing a hole and forging the forging process part to have a flat structure after the step of S120.
