Abstract
(EN)
Provided are a bent member having a bend having a minute bend radius which is, for example, not more than 1 to 5 times the thickness of the member, and a device and a method for manufacturing the bent member. A first support means (11) disposed at a first position (A) supports a rectangular pipe (16) while feeding the rectangular pipe (16) in the longitudinal direction, a heating means (12) disposed at a second position (B) partially heats the rectangular pipe (16), and a cooling means (13) disposed at a third position (C) cools the rectangular pipe (16). When working the rectangular pipe (16), a shear force application means (14) which is disposed in a downstream region (D) is moved two-dimensionally or three-dimensionally in two directions at the same time, the two directions being the feeding direction of the rectangular pipe (16) and the direction substantially parallel to one lateral cross-section of the rectangular pipe (16), said lateral cross-section being located at a position in the longitudinal direction and being that which is heated by the heating means (12). By doing so, a shear force is applied to the heated portion of the rectangular pipe (16), and as a result, a bent member (21) is manufactured.

L'invention concerne un élément plié ayant un rayon de courbure minime, qui est par exemple d'au plus 1 à 5 fois l'épaisseur de l'élément et un dispositif et procédé de fabrication dudit élément plié. Un premier moyen de support (11) disposé dans une première position (A) supporte un conduit rectangulaire (16) tout en amenant le conduit rectangulaire (16) dans le sens longitudinal, un moyen de chauffage disposé dans une seconde position (B) chauffe partiellement le conduit rectangulaire (16) et un moyen de refroidissement (13) disposé dans une troisième position (C) refroidit le conduit rectangulaire (16). Lors d'un travail du conduit rectangulaire (16), un moyen d'application de force de cisaillement (14) disposé dans une zone en aval (D) est déplacé en deux ou en trois dimensions dans deux directions en même temps, les deux directions étant la direction d'alimentation du conduit rectangulaire (16) et la direction sensiblement parallèle à une section transversale latérale du conduit rectangulaire (16), ladite section transversale latérale étant située dans une position dans la direction longitudinale et étant celle qui est chauffée par le moyen de chauffage (12). Ainsi, une force de cisaillement est appliquée à la partie chauffée du conduit rectangulaire (16) et par conséquent, un élément plié (21) est fabriqué.
