摘要： A method is used to manufacture a tube having a hollow interior for housing an axle shaft. The tube is formed in a single machine having a fixed base and a single press structure movable toward the fixed base. The single machine includes first and second die assemblies coupled to the fixed base and first and second mandrels coupled to the single press structure. The method includes the steps of placing a billet into the first die assembly, pressing the billet into the first die assembly with the first mandrel to producing a pre-formed billet, and moving the pre-formed billet from the first die assembly to the second die assembly. THE method further includes the steps of pressing the pre-formed billet into the second die assembly with the second mandrel to elongate the pre-formed billet and form a hollow interior therein to produce an extruded tube.

摘要： A damper housing disposed on a center axis includes an extended mains section and a narrowed end section. The narrowed end section has a second predetermined wall thickness less than the first predetermined wall thickness of the extended main section. An intermediate conical section, connecting the narrowed end section and the extended main section, has an intermediate conical section wall thickness equal to the second predetermined wall thickness at an internal inclination angle relative to the center axis. A method for manufacturing the damper housing using a preformed tube, a first broaching die, a calibrating mandrel, and a swaging die is performed by compressing the preformed tube between the first broaching die and the narrowed head of the calibrating mandrel and compressing the preformed tube between the swaging die and the intermediary section of the calibrating mandrel to form the narrowed end section and the intermediate conical section, respectively.

摘要： A method of preparing a cylindrical metal member includes preparing a metallic ingot having at least one surface having a mean width with respect to roughness Sm in a range of from 100 μm to 220 μm; imparting a lubricant to the at least one surface of the metallic ingot; and subjecting the metallic ingot to impact pressing while the surface coated with the lubricant with respect to the metallic ingot is set as a bottom surface, to thereby mold a cylindrical metal member.

摘要： A cylindrical bearing member, which can hold lubricating oil in blind grooves as oil reservoirs for a long period of time to exhibit a lubricating function sufficiently, the blind grooves being efficiently mass-produced on the inside of the cylindrical member at low cost. The cylindrical bearing member has an inner circumferential surface having a plurality of blind grooves and is formed as a hollow open-ended cylindrical member with a bottom from a circular column-shaped crude material or blank. The blank includes a tapered inner circumferential surface at its open end. A groove forming die pin including groove forming protrusions is pushed from the open end towards the bottom to obtain a cylindrical member in which a plurality of grooves are formed on the inner surface. The grooving die pin is removed, then the tapered inner circumferential surface of the cylindrical member 107 is returned and straightened to a cylindrical shape to close the grooves at the open end of the member, and then the bottom is removed from the cylindrical member.
