    Abstract: 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.

    Abstract: 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.

    Abstract: A metal mold is disposed adjacent to the outer circumference of a base ring, and has a molding face in the inner circumference and a plurality of grooves for forming beads on the molding face along the circumferential direction. A coil for electromagnetic forming is disposed adjacent to the inner circumference of the base ring. When a momentary large current is applied to the coil in this arrangement, the diameter of the base ring is expanded by pressing the base ring toward the molding face of the metal mold such that the base ring is molded into a shape corresponding to the molding face by electromagnetic forming. Improvements such as a metal mold capable of degassing, a separable metal mold, roll-correcting after electromagnetic forming, application of momentary large current over several times, a metal mold with a cutting blade, use of a base ring with a large number of holes, and a metal mold with positioning means are then added. With these improvements, a highly accurate cylindrical ring with beads can be produced at low cost and with high productivity.

    Abstract: An automotive frame is assembled by joining fins of extrusions formed of aluminum alloy by resistance spot welding. The fins are formed integrally with each extrusion by extrusion. Alternatively, the extrusions may be joined together through a node part having fins. In this case, the fins of each extrusion are joined by resistance spot welding to the fins of the node part. The node part includes a body formed by extrusion and a side plate penetration-welded to the body by laser welding. The side plate functions as the fins of the node part.
