Title (EN) MOLD PIN FOR MANUFACTURING TUBE YOKE
(FR) BROCHE DE MOULE POUR LA FABRICATION D'UN ÉTRIER DE TUBE
(KO) 튜브요크 제조용 성형핀
Abstract: front page image
(EN)The present invention relates to a mold pin 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 mold pin for manufacturing the tube yoke, according to the present invention, is provided with a spline part on the outer circumferential surface thereof to form the spline on the inside of the tube part of the tube yoke comprising the tube part and a yoke part, wherein a land part protruding along the outer circumferential direction is formed on the spline part corresponding to one side in the lengthwise direction of the mold pin.
(FR)La présente invention concerne une broche de moule destinée à la fabrication d'un étrier de tube, capable de fabriquer rapidement un étrier de tube pourvu d'une cannelure sur une partie de tube par l'intermédiaire d'une étape de forgeage tout en empêchant la distorsion induisant une forme torsadée de la cannelure. A cet effet, la broche de moule pour fabriquer l’étrier de tube selon la présente invention, est pourvue d'une partie cannelée sur sa surface circonférentielle externe pour former la cannelure sur l'intérieur de la partie tube de l’étrier de tube comprenant la partie tube et une partie étrier, une partie d'appui saillant le long de la direction circonférentielle externe étant formée sur la partie de cannelure correspondant à un côté dans le sens de la longueur de la broche de moule.
(KO)본 발명은 단조 공정을 통해 튜브부에 스플라인이 형성된 튜브요크를 빠르게 제조할 수 있고, 스플라인의 형상이 뒤틀리는 왜곡을 방지할 수 있는 튜브요크 제조용 성형핀에 관한 것이다. 이를 위한 본 발명의 튜브요크 제조용 성형핀은, 튜브부와 요크부로 이뤄진 튜브요크의 튜브부 내측에 스플라인을 성형하기 위해 외주면에 스플라인부가 형성된 튜브요크 제조용 성형핀으로서, 상기 성형핀의 길이방향 일측에 대응하는 스플라인부에는 외주방향을 따라 돌출된 랜드부가 형성된다.
