Abstract

1,075,816. Stamping; jointing by tubeexpanding. GENERAL DYNAMICS CORPORATION. March 5, 1965 [March 11, 1964], No. 9438/65. Headings B3J and B3Q. A method of forming a workpiece comprises placing a deformable pressure-transmitting medium or a liquid between the workpiece and a conductive driver and establishing a varying magnetic field to intersect the driver so as to force the driver against the medium or the liquid and the medium or liquid against the workpiece. A pad of rubber 20 may be used between a workpiece 22 and the cylindrical copper or aluminium driver 19 disposed on the flat forming coil 10. A die 24 is disposed above the work. The forming pressure may be intensified by tapering the driver (35, Fig. 2), which has three parts connected together, and confining the transmission medium (40) in a ring (41). As applied to shaping tubular work (58, Figs. 3 and 4) within a rubber sleeve (54), this is surrounded by a corrugated, aluminium or beryllium-copper, flexible driving sleeve (52). A split field shaper (48), with or without a corrugated bore, is arranged between the driver (52) and the coil (46), and the sleeves (52, 54) are confined endwise between members (60). The coil may be cooled, and the driver (52) formed of several layers. An internal die or mandrel may be used in the tube (58). Tubular work (58a, Fig 8) may be expanded by an internal coil assembly (63), acting through a corrugated driving sleeve (52a) and a flexible ring (54a). As applied to expanding the end of a tube (78, Fig. 6) in a tube plate (80), a plug of rubber (86) is expanded by a driver (84) operated by an external coil (82). A similar coil-and-driver arrangement acting on oil or paraffin (96, Fig. 7) may be used to subject work (90) to radial compression.
