Abstract (en)

[origin: WO2005110638A1] A device for shaping a beam from a blank is disclosed, the blank being a profile element in the form of a beam having a closed cross-section, end portions (1A, 1B), a centre portion (1C) and a front flange, a rear flange, an upper web and a lower web. The beam is to be heated to an austenitizing temperature for quenching. The device is characterized in that it comprises an upper tool part (3) and a lower tool part (4) arranged to receive the heated beam blank and shape it, the device comprises a part (9, 9A, 9B) arranged to impress end portions (1.2a) of the rear flange, so that the beam (1) after the shaping has the greatest volume at the centre portion and the smallest volume at the ends (1A, 1B) along a certain distance (X), and parts to bend the beam end portions. The device also comprises means for directing a cooling medium through the internal cavities of the beam. The invention also relates to methods for shaping and quenching hollow beams.
