CA 2687025

The invention relates to a device and method for bending pipes, said device comprising a feed device (4) for the pipe (2), which feeds the pipe (2) continuously in the longitudinal direction, a heating device (5) located in the feed direction for heating one region of the pipe (2) and a bending arm (7), which can be pivoted about a rotational axis (D) and comprises a holding device (6) for the pipe (2). The pipe (2) can be removably fixed in the holding device (6). The aim of the invention is to provide a device and a method for bending pipes with which the pipe can be bent in different bending directions. To achieve this, the feed device (4) and the bending arm (7) can moved in relation to one another in such a way that the feed device (4) and the rotational axis (D) of the bending arm (7) can be moved past one another.

L'invention concerne un dispositif et un procédé de cintrage de tubes, comprenant un dispositif d'avance (4) pour le tube (2), lequel dispositif fait avancer le tube (2) en continu dans le sens longitudinal, un dispositif de chauffe (5), placé dans le sens de l'avance et destiné à chauffer une zone du tube (2), ainsi qu'un arbre de cintrage (7), pouvant pivoter autour d'un axe de rotation (D) et pourvu d'un dispositif de maintien (6) pour le tube (2), ledit tube (2) pouvant être fixé de façon amovible dans le dispositif de maintien (6). L'objectif de l'invention est de réaliser un dispositif et un procédé de cintrage de tubes, permettant un cintrage du tube dans différentes directions de cintrage. A cet effet, le dispositif d'avance (4) et le bras de cintrage (7) sont mobiles l'un par rapport à l'autre, de sorte que le dispositif d'avance (4) et l'axe de rotation (D) du bras de cintrage (7) peuvent être amenés à proximité l'un de l'autre.
