摘要： A metal mold for electromagnetic forming, with the inner peripheral face thereof, serving as a forming face, is disposed on the outer peripheral side of a columnar workpiece, and a coil for electromagnetic forming is disposed on the inner peripheral side of the columnar workpiece. In a state of a configuration as described, electric energy is thrown into the coil for the electromagnetic forming, and the columnar workpiece is caused to undergo flaring to be thereby pressed against the forming face of the metal mold for the electromagnetic forming, so as to be turned into a shape corresponding to the forming face by means of the electromagnetic forming, thus obtaining a wheel rim. A disc is welded to the wheel rim obtained, and curling is applied to outer edges of the wheel rim. With the adoption of a method of manufacturing an automotive wheel, a manufacturing process as a whole is enhanced in efficiency.

摘要： A target tubular member with flange, such as a bumper stay, has a flange having an outer diameter larger than the diameter of an axial section and is formed by electromagnetic forming without excessive expansion. The tubular member with flange includes an axial member made of a tubular aluminum alloy extrudate and a flange member joined to an end of the axial member. The axial member has an end flange being integrated at its end and having an area smaller than that of the flange member. The flange member has a hole, and a cylindrical hole flange at the edge of the hole. The axial member fits in the hole of the flange member, the end flange is in intimate contact with the flange member, and the outer periphery of a small-diameter portion of the axial member is in intimate contact with the inner periphery of the hole flange. The hole flange is held between the end flange and a protrusion. The tubular member with flange may be produced by inserting an untreated pipe into the hole of the flange member and expanding the untreated pipe by electromagnetic forming.

摘要： Provided is an electromagnetic pipe expanding inductor in which the formation of voids during resin impregnation is suppressed, and electromagnetic reaction forces acting on the conductor periphery and on the interface between the shaft portion and the center-side fiber layer is diminished, and thereby durability is improved and the life of the inductor is prolonged. A glass cloth tape (3) capable of being impregnated with resin is wound around the peripheral surface of a shaft portion of a bobbin (2) to a predetermined thickness, further, a conductor strand (4) coated with a glass cloth tape (6) is wound spirally in the axial direction of the bobbin (2) to form a coil. Further, a glass cloth (7) is wound around the outside of the glass cloth tape (6) to a predetermined thickness and thereafter the glass cloth tapes (3, 6) and the glass cloth (7) are impregnated with resin to unite them. A center-side resin-impregnated layer formed by the glass cloth tape 3 impregnated with resin is lower in the modulus of longitudinal elasticity than the shaft portion. Given that the inductor radius is r, the thickness, t, of the center-side resin-impregnated layer is 0.025r to 0.25r.

摘要： A joint member is used for positioning a first square tubular section made of aluminum or aluminum alloy and a second square tubular section made of aluminum or aluminum alloy with the sections' end portions butting against each other so as to weld the butt end portions together. The joint member includes an angle retainment portion and first and second anchorage portions. The angle retainment portion is applied onto the outer or inner surfaces of walls of the first and second square tubular sections, the walls intersecting each other with an angle equal to or smaller than 180.degree. when the first and second tubular sections are caused to butt against each other. The first and second anchorage portions branch off and extend from the angle retainment portion so as to fixedly hold the walls of the first and second square tubular sections, respectively, in cooperation with the angle retainment portion. The joint member facilitates and speeds the setting of the square tubular sections and thus improves setting workability while maintaining an advantage of a manufacturing method for a welded structure in which sections are directly welded without using connection members.

摘要： A method prevents a cylindrical body from buckling in externally curling edges of both side portions by pressing curling dies in an axial direction after molding the cylindrical body having a drop portion whose outer diameter is small and two side portions whose outer diameter is large by enlarging a cylindrical material made of aluminum alloy by electromagnetic molding. In curling the edges of the side portions, a buckling preventing die restrains an outer periphery of the drop portion of the cylindrical body. Because the buckling preventing die receives the axial compression force of the curling dies, it can prevent the cylindrical body from buckling and deforming. The buckling preventing die is what a split die disposed on the side of an outer periphery of the cylindrical material in the electromagnetic molding is used as.
