Title
(EN) Method of manufacturing outer ring member for constant velocity joint
(ZH) 用于等速接头的外环部件的制造方法
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).

(ZH)

一种用于等速接头的外环部件的制造方法,包括以下步骤:在对工件(10)进行正挤压成型(S1)之后,通过对该工件(10)进行初步镦锻而形成二次模制件(20)(S2);通过对所述二次模制件(20)的上部(22)进行镦锻而形成中间预模制体(24,24a),在其上形成有环形斜面(36,36a)以在较大直径部分(28a至28c)和较小直径部分(30a至30c)之间具有流阻差(S3,S3a);通过对所述中间预模制体(24,24a)进行反挤压成型而形成具有带有轨道槽(60a至60c)的杯部分(62)的四次模制件(58)(S4);以及对所述四次模制件(58)的杯部分(62)进行挤拉,以将所述四次模制件(58)精加工成产品尺寸(S5)。
