Disclosed is a method for hot flow forming and bending closed, half-open, and open profiled members. Said method uses a bending machine comprising at least two rollers (17, 18) which are disposed across from each other in the feeding direction of the bending profiled member and behind which at least one milling roller (14) and an opposite central roller (11) are arranged at an axial distance in the feeding direction, said at least one milling roller (14) and central roller (11) jointly embodying a roll bending zone for the profiled member that is to be shaped. At least one bending roller (13) which can be moved against and away from the profiled member that is to be bent is arranged at the discharge end. In order to be able to shape thin-walled and sensitive open, half-open, and closed profiled members, at least the rollers (11, 14) located in the roll bending zone are heated.
L'invention concerne un procédé de formage et de pliage par fluage à chaud de profilés fermés, ouverts et mi-ouverts. Ce procédé fait appel à une machine de pliage comprenant au moins deux rouleaux (17, 18) se faisant face dans le sens d'entrée du profilé à plier et, derrière ces rouleaux, à une distance axiale dans le sens d'entrée du profilé, au moins un rouleau de laminage (14) et un rouleau médian (11) lui faisant face, ces deux derniers rouleaux formant ensemble une zone de cintrage pour le profilé à usiner, au moins un rouleau de cintrage (13) se trouvant côté sortie et pouvant être approché et éloigné du profilé à plier. L'invention vise à permettre la déformation plastique par flexion de profilés sensibles à parois minces, fermés, ouverts et mi-ouverts. A cet effet, les rouleaux (11, 14) montés dans la zone de cintrage au moins sont chauffés.
