摘要： A method of, and an apparatus for extruding a billet of a light metal alloy, wherein the billet has an outer diameter smaller than a maximum configuration width and larger than a minimum configuration width of the die hole at its entry side. The billet is pressurized and extruded by a stem to form a preshaped portion which is larger than the entry side configuration of the die hole, at a frontal end portion of the billet near an entry portion of the die hole. The preshaped portion of the billet is subsequently shaped by the die hole into an extruded shape corresponding to the cross-sectional shape of the die hole and of parts formed from the extruded billet, e.g., of an automobile suspension arm. A reduced resistance and a minimized extrusion pressure upon extrusion of a light metal alloy result from the preshaping of the billet and enable realization of a compact and less expensive arrangement of the production facility.

摘要： A method of and an apparatus for extruding a billet of a light metal alloy, wherein the billet has an outer diameter smaller than a maximum configuration width of the die 2 at its entry side. The billet is pressurized and extruded by a stem 5 to form a preshaped portion via die 2 which is greater than the entry side configuraton of the die 1 at a frontal end portion of the billet near an entry portion of the die hole. The billet is subsequently shaped by the die 1 into an extruded shape corresponding to the cross-sectional shape, e.g. of an automobile suspension arm. A reduced resistance and a minimized extrusion pressure upon extrusion of a light metal alloy enable realization of a compact and less expensive arrangement of the production facility.

摘要： PROBLEM TO BE SOLVED: To attain the optimum decentralization of each step by reducing the forming rate of a fourth step of forming a ball rolling groove. SOLUTION: In a first step, a work 10 is subjected to the forward extrusion to form a first formed article 40, and in a second step, the upset forming is performed to form a second formed article 50. Successively, in a third step, the preliminary extrusion is performed on an upper face of the second formed article 50 to form a third formed article 60 in which a recess 62 substantially matched with the longitudinal sectional shape in the axial direction of a bottom wall 32 of a cup part of a final product is formed in the upper face. In a fourth step, the backward extrusion is performed on the third formed article 60 by using a punch having a tip shape substantially matched with the longitudinal sectional shape of the recess 62 to form a fourth formed article 70 having a cup part with a ball rolling groove formed in an inner wall thereof. Finally, in a fifth step, the cup part of the fourth formed article is ironed to manufacture an outer wheel member 12 as the final product. COPYRIGHT: (C)2007,JPO&INPIT
