摘要： PROBLEM TO BE SOLVED: To provide a technique which reduces both a material cost and a processing cost in an outer ring of a universal joint consisting of a cup part and a hollow part.
SOLUTION: In an intermediate product 10 before a finishing process of the outer ring of the universal joint, which consists of the cup part 11 and the hollow shaft part 12 extending from this cup part 11, a plurality of guide grooves extending in the axial direction are provided inside the cup part. Recessed grooves 13, 13 are formed between a pair of guide grooves on the cup part by a molding roller so as to protrude to the radius center, and at the end remotest from the hollow shaft part 12, protruding parts 14 are formed such that the parts of the recessed grooves 13 protrude in the axial direction from the parts of the guide grooves. The cup part and the hollow shaft parts are integrally molded thereby, so that a process of connecting the hollow shaft part to the cup part is not required, and the processing cost is reduced. The cup part and the hollow shaft part are integrated, so that the yield of a material is good and the material cost is reduced.

摘要： PROBLEM TO BE SOLVED: To provide a die apparatus and method for forming an outer race for constant velocity joint with a stem suitable to secure high degree of the same axle of a cup part and a stem part.
SOLUTION: On the inner peripheral surface of the cup part W1 of a rough-material W providing the cup part W1 with the stem roughly forming the inner peripheral surface so as to approach with the inner peripheral surface of the outer race in the constant velocity joint, a sizing punch 4 provided with the outer peripheral surface shape machined as the inner peripheral surface of the outer race in the constant velocity joint is fitted and a stem part W2 connected with the cup part W1 of the rough-material W is penetrated into a sizing die 5 and while holding the same center state with the axial center of the sizing die 5 in the front part, this rough-material is held with an axial restricting means 8 to be movable in the direction of the axial center. Then, in the holding state with the above axial restricting means 8, an ironing processing is applied with the sizing die 5 to the outer periphery of the cup part W1 of the rough-material W so as to finish-form the inner peripheral surface of the cup part W1 into the inner peripheral surface state of the outer race for constant velocity joint.

摘要： PROBLEM TO BE SOLVED: To provide a press-forming die and a method for manufacturing a double-helical gear with which the double-helical gear having high precision can be obtained. SOLUTION: A rotating member 17 integrally rotated with a rotating block 14, is arranged in the turning block 14 supported turnably by a punch-holer and a regulating member 18 is arranged in a base plate fixed to a ram in a press-forming machine, and since an angle-phase around an axis to the die in a punch is returned back to the initial stage phase by abutting a plate 19 in the rotating member 17 on a standard block 21 in the regulating member 18, the punch can surely be returned back to the initial stage phase at the high precision. In this way, the double-helical gear forming the angle-phase around the axis among the respective helical tooth-shapes at the high precision, can be obtained. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a press-forming die and a method for producing a double helical gear with which the double helical gear having high precision can be obtained by correcting an angle phase at the initial stage around the axial lines of an upper die and a lower die according to mechanical characteristics of a blank, and a forming condition such as a lubricating condition. SOLUTION: A punch is fitted to a rotary block 14 by supporting the rotary block 14 so as to be rotatable with a punch holder and also, a rotary member 17 integrally rotating the rotary block 14, is arranged in the rotary block 14. Further, a regulating member 18 is arranged on a base plate and the plate 19 of the rotary member 17 is abutted on a reference block 21 of the regulating member 18 and the angle phase around the axial lines of the punch 6 and the die 7 is returned back to the initial phase. Therefore, the punch and the die are surely returned back to the initial phase with high precision, and thus, the angle phase around the axial lines among respective helical teeth in the double helical gear, is formed with high precision.
