    摘要: A torque converter comprises an impeller shell, a pump impeller integrally formed with the impeller shell, a turbine runner, a stator, a front cover, and at least one of a flanged portion through which a driving power of an engine is transmitted and a ring gear for a starter. The flanged portion is formed on an outer peripheral portion of an outer hull that includes the impeller shell and the front cover. A pilot boss portion is disposed at an axial portion of the front cover and is adapted to be fitted to a crank shaft of the engine, and a sleeve-like oil pump driving shaft is disposed at an axial portion of the impeller shell and is adapted to drive an oil pump. The pilot boss portion is formed integrally with the front cover through a plastic working operation, and the flanged portion formed at a front portion of the outer periphery of the front cover is increased in thickness through a plastic working operation that forms the flanged portion as a lamination.

    摘要: A method is required in which a plate-like flange member may be firmly secured at the front end of a hollow shaft member through a plastic working treatment by virtue of caulking combination, so as to manufacture a hollow shaft having a flange at one end thereof. In detail, the method comprises preparing a plate-like flange member A having an axial projection 13 including a constricted portion 13a on one side thereof; preparing a hollow shaft member B having an elongate internal space arranged in the axial direction thereof; engaging the axial projection 13 of the plate-like flange member A into a front end portion of the hollow shaft member B and at the same time inserting a mandrel 15 into the hollow shaft member B; pressing the hollow shaft member B in its axial direction towards the plate-like flange member A while performing a shear spinning treatment on the outer periphery surface of the hollow shaft member B so as to reduce the size of the hollow shaft member B in its radial direction; engaging the front portion of the hollow shaft member B with the constricted portion 13a of the axial projection 13 of the plate-like flange member A by virtue of caulking combination.

    摘要: A hollow stepped article is formed from a solid blank to reduce the material cost, and cracking is prevented in a stepped portion of large diameter when a portion of the blank is deformed by its radial expansion. A hollow stepped shaft is formed by holding an upper and a lower part axially of a solid rod-like blank with an upper and a lower die, respectively, which have a stepped recess of large diameter in a region where they are opposed to each other; compressing the blank from both its axially opposite sides with an upper and a lower punch each of which is smaller in diameter than the blank, thereby extruding the blank so that an axial hollow is formed therein about its axis in each of its upper and lower parts and that a portion of the blank opposed to the stepped recess of large diameter expands in diameter and deforms into that recess while leaving a solid plug-like portion between the punches; and thereafter further compressively moving one of the punches to shear the solid plug-like portion and force it out of the blank, whereby the blank is formed with a stepped portion of large diameter by radially expanding deformation in a region intermediate between its opposed ends or at one of these ends and with a continuous axial hollow about its axis.

    摘要: A hollow step-profiled shaft such as a cam shaft that is high in accuracy and excellent in productivity and requires little post-machining is being formed. To this end, a hollow stepped shaft 8 having its axis and large diameter portions 9a-12b intermediate axially between its ends is formed by a forming process in which each large diameter portion of the shaft is compressed with forming dies 32a-32d from at least three different directions approximately simultaneously towards the axis to shape the large diameter portion with a profile such as to conform to contours 38a-38d of a cavity 38 formed in a region of tips of the forming dies 32a-32d.
