Abstract (en)
[origin: EP0695592A1] The method for shaping a metal tube by electromagnetism is characterised by: (a) a section of a metal tube (2) being placed between a means (1) capable of producing a magnetic field and a means (4) with required surface shape; (b) the device (1) being electrically activated to produce a force which deforms the tube wall and presses it against the means (4); (c) the means (1) and (4) being displaced longitudinally into another position along the length of the tube for continuation of the shaping process. The appts. incorporates means for longitudinal displacement of the tube relative to the means (1, 4) for step-by-step shaping of the tube (2).
