(EN) METHOD OF MANUFACTURING OUTER RING MEMBER FOR CONSTANT VELOCITY JOINT
(FR) PROCEDE POUR PRODUIRE UN ELEMENT ANNULAIRE EXTERIEUR POUR UN JOINT HOMOCINETIQUE
(JA) 等速ジョイント用外輪部材の製造方法
Abstract
(EN)
A method of manufacturing an outer ring member for a constant velocity joint, comprising the steps of forming a secondary molding (20) by applying a preliminary upsetting to a work (10) after applying a forward extrusion-molding (S1) to the work (10) (S2), forming intermediate pre-molded bodies (24, 24a) having annular sloped surfaces (36, 36a) formed thereon to have a difference in flow resistance between large diameter parts (28a to 28c) and small diameter parts (30a to 30c) by applying the upsetting to the upper part (22) of the secondary molding (20) (S3, S3a), forming a quaternary molding (58) having a cup part (62) with track grooves (60a to 60c) by applying a backward extrusion-molding to the intermediate pre-molded bodies (24, 24a)(S4), and applying an ironing to the cup part (62) of the quaternary molding (58) to finish the quaternary molding (58) to product dimensions (S5).
(FR)
L'invention concerne un procédé pour fabriquer un élément annulaire extérieur pour un joint homocinétique, comprenant les étapes suivantes : formation d'un moulage secondaire (20) par application d'un refoulement préliminaire sur une pièce (10) après application d'un moulage par extrusion (S1) avant sur la pièce (10) (S2) ; formation de corps (24, 24a) prémoulés intermédiaires présentant des surfaces annulaires (36, 36a) coniques présentant une différence dans la résistance à l'écoulement entre les parties à large diamètre (28a à 28c) et les parties à petit diamètre (30a à 30c) par application d'un refoulement à la partie supérieure (22) du moulage secondaire (20 (S3, S3a) ; formation d'un moulage quaternaire (58) présentant une partie coupelle (62) à rainures (60a à 60c) par application d'un moulage par extrusion arrière aux corps prémoulés intermédiaires (24, 24a) (S4) ; et application de réduction de paroi sur la partie coupelle (62) du moulage quaternaire (58), ceci finissant le moulage quaternaire (58) et permettant de produire des dimensions (S5).
(JA)
 ワーク(10)に対して前方押し出し成形(S1)を施した後、前記ワーク(10)に予備据え込み成形を施して第2次成形品(20)を形成し(S2)、前記第2次成形品(20)の上部(22)に対して据え込み成形を施すことにより、大径部(28a~28c)と小径部(30a~30c)との間で流動抵抗差を有する環状傾斜面(36、36a)が形成された中間予備成形体(24、24a)を形成し(S3、S3a)、前記中間予備成形体(24、24a)に対して後方押し出し成形を施すことによりトラック溝(60a~60c)が設けられたカップ部(62)を有する第4次成形品(58)を形成し(S4)、さらに、前記第4次成形品(58)のカップ部(62)に対して製品寸法に仕上げるしごき成形を行う(S5)。
