    摘要: PROBLEM TO BE SOLVED: To provide a manufacturing method of a pulley for a continuously variable transmission which can easily form a cylinder part after carburizing and quenching, when the cylinder part is formed integrally from a movable flange workpiece. SOLUTION: The pulley for the continuously variable transmission comprises a stationary flange 6 fixed to a rotary shaft 5, a movable flange 7 reciprocally movable in the axis direction of the rotary shaft 5, and the cylinder part 9 to form a pressure chamber 11 arranged integrally in the movable flange 7. The movable flange workpiece 21 with a preparatorily shaped part 23 to form the cylinder part 9 is formed by hot forging. The movable flange workpiece 21 is subjected to carburizing and quenching after the preparatorily shaped part 23 is attached and covered with a thermal conduction restraining jig 24. After the thermal conduction restraining jig 24 is detached, the heat hardened part in the surface of the preparatorily shaped part 23 is removed. The preparatorily shaped part 23 after the removal of the heat hardened part is drawn into the cylinder part 9. The thermal conduction restraining jig 24 is attached to the preparatorily shaped part 23 having a decarburization agent layer 26 between them. COPYRIGHT: (C)2005,JPO&NCIPI

    摘要: PROBLEM TO BE SOLVED: To increase productivity and yield of material by forming a hollow shaft pulley by forming, to increase strength by forming a high density region of a material fiber flow in a shaft part on the cone surface side of a pulley part, and to reduce abrasion and damage of this part by making the material fiber flow on the cone surface spiral.
    SOLUTION: The columnar material 5 is formed by upsetting to form a shaft part 6a and a swelling part 6b swelling to a large diameter at its one end. The outer periphery of the swelling part 6b is axially oscillated and forged, the material fiber flow is made to flow spirally and plastically to be deformed to a large diameter, thereby a conical pulley part 7c is formed. The shaft part 6a is backward extruded to form hollow shaft parts 8a and 8b having a solid part 8d in the shaft core part of the pulley part 7c.

    摘要: PROBLEM TO BE SOLVED: To solve problems in a pully unit wherein another process is required such as forming an annular groove for processing a metallic piece generated when plastically working a serration in a rotary operational recessed part, an axial directional width of the serration becomes short by the extent of forming the annular groove, and the width is insufficient when requiring high fastening torque. SOLUTION: When forming the rotary operational recessed part 2a by arranging an advance part 25 for forming a second annular inclined face 24 inclining so as to diametrally contract toward the axis 20 in a work tool 28 for forming the rotary operational recessed part 2a, the thickness of an outer peripheral surface part of a rotary operational recessed part forming hole 26 easily flows to the inmost part, and even if one-way clutch 3 is arranged in an annular space between both annular bodies 1 and 2, since there is no need to form a groove for removing the metallic piece, the width of the serration 22 can be secured long by that extent, and manhours can be reduced.

    摘要: PROBLEM TO BE SOLVED: To efficiently form a disk parts with shaft without developing void (crack) at a low cost. SOLUTION: Temp. distribution just before forming is the highest temp. at a portion S0 corresponding to the outer peripheral part of the disk part after forming, and becomes gradually lower temp. toward the center part SI in the radial direction and toward the end parts in the shaft direction from the highest portion. Then, at the time of upset-forming a bar-like blank in the temp. distribution, such as the above state, the highest temp. portion is shifted to the outside without leaving in the center part. Further, simultaneously, the temp. is ordinarily raised with heat-generation according to the compressive deformation to the center part SI in the radial direction during forming, but in this case, since the portions 10a corresponding to the shaft parts at the lower temp. exist at the upper and the lower parts of the center part SI in the radial direction, these portions 10a are acted as chiller to restrain the heat-up at the center part SI in the radial direction.
