Abstract

본 발명은 단면이 원형상인 소재를 성형공정에 의하여 한쪽면이 라운딩면을 가지는 장방형상의 단면으로 소재를 성형하여, 이 소재가 코일 형상의 성형에 의하여 단위면적의 안쪽 모서리에 라운딩면이 형성되도록 하므로써, 코일스프링의 최대 압축시 서로 대향하는 면이 면접촉으로 안정성있게 유지할 수 있는 단면이 장방형상인 코일스프링의 제조방법에 관한 것으로, 단면이 원형상인 소재를 제1압연로울(110)에 의하여 서로 대향하면 평면 및 라운딩면을 가지는 준장방향상의 단면(120)으로 성형하는 제1성형 공정(100)과; 제1성형공정(100)에 이어서 제2압연로울(210)에 의하여 한쪽면에 라운딩면을 가지는 장방형상의 단면으로 성형하는 제2성형공정(200)과; 제2성형공정(200)의 성형소재를 코일형상으로 성형하는 제3성형공정(300)을 거치면서 얻은 코일 스프링(400)의 단위면적의 안쪽 모서리면이 라운딩면(410)으로 성형되도록 한 것이다.According to the present invention, a material having a circular cross section is molded into a rectangular cross section having a rounded surface on one side by a molding process, so that the rounded surface is formed at the inner edge of the unit area by the coil shape. The present invention relates to a method of manufacturing a coil spring having a rectangular cross section in which surfaces facing each other at the time of maximum compression of the coil spring can be stably maintained by surface contact, and the material having a circular cross section is opposed to each other by the first rolling roll 110. A first molding process (100) for shaping into a cross section (120) in a quasi-span direction having a lower surface plane and a rounding surface; A second molding step 200 for molding into a rectangular cross section having a rounding surface on one side by a second rolling roll 210 after the first molding step 100; The inner edge surface of the unit area of the coil spring 400 obtained through the third molding process 300 for molding the molding material of the second molding process 200 into a coil shape is molded into the rounding surface 410. .
