Title (EN) METHOD FOR MANUFACTURING TUBE YOKE
(FR) PROCÉDÉ DE FABRICATION D'UN ÉTRIER DE TUBE
(KO) 튜브요크 제조방법
Abstract: front page image
(EN)The present invention relates to a method for manufacturing a tube yoke, capable of rapidly manufacturing a tube yoke provided with a spline on a tube part through a forging step while preventing distortion involving a twisted shape of the spline. To this end, the method for manufacturing the tube yoke, according to the present invention, comprises: a tube yoke forge-molding step of injecting a material into dies and pressing with a punch to mold the tube yoke comprising the tube part and a yoke part; and a spline forge-molding step of forming the spline on the inside of the tube part by inserting, into the tube part, a mold pin provided with a spline part on the outer circumferential surface thereof.
(FR)La présente invention concerne un procédé de fabrication d'un étrier de tube, capable de fabriquer rapidement un étrier de tube pourvu d'une cannelure sur une partie tube par l'intermédiaire d'une étape de forgeage, tout en empêchant la distorsion induisant une forme torsadée de la cannelure. A cet effet, le procédé de fabrication de l'étrier de tube selon la présente invention comprend : une étape de moulage par forgeage d’étrier de tube, consistant à injecter un matériau dans des matrices et à presser avec un poinçon pour mouler l’étrier de tube comprenant la partie tube et une partie étrier ; et une étape de moulage par forgeage de cannelure, consistant à former la cannelure sur l'intérieur de la partie tube par insertion, dans la partie de tube, d’une broche de moule pourvue d'une partie de cannelure sur sa surface circonférentielle externe.
(KO)본 발명은 단조 공정을 통해 튜브부에 스플라인이 형성된 튜브요크를 빠르게 제조할 수 있고, 스플라인의 형상이 뒤틀리는 왜곡을 방지할 수 있는 튜브요크 제조방법에 관한 것이다. 이를 위한 본 발명의 튜브요크 제조방법은, 소재를 다이스에 삽입하고 펀치로 가압하여 튜브부와 요크부로 이뤄진 튜브요크를 성형하는 튜브요크 단조성형공정; 및 외주면에 스플라인부가 형성된 성형핀이 상기 튜브부의 내부로 삽입되도록 하여 상기 튜브부의 내측에 스플라인을 성형하는 스플라인 단조성형공정;을 포함하여 구성된다.
