Abstract (en)
[origin: CA2798350A1] A machine for bending tubes of large diameter in different bending directions, wherein, for bending, in this machine a tube (10) is guided in the axial direction through an inductive heating device (7) enclosing this tube in an annular manner, the tube (10) is secured by a bending lock (4) at the end (11) thereof intended to be bent, at least one bending arm (2), which is mounted rotatably about a vertical axis of rotation (8), is located at the part of the bending machine that is disposed in the advancing direction of the tube (10), the bending lock (4) is indirectly connected to the bending arm (2), the bending lock (4) has a force transmission device between the receiving device for tubes and the bending arm (2), the force transmission device is connected to the bending arm (2) such that it can be set so as to allow the distances between the centre axis of the receiving device for tubes and the vertical axis of rotation (8) to be chosen between the smallest distance and greatest distance, whereby a range between a greatest and a smallest bending radius (12) can be set, the machine has at least one further bending lock (5) with a further bending arm (3), a receiving device for tubes and a force transmission device for bending forces from the receiving device to the further bending arm (3), wherein the direction of rotation of the further bending arm (3) is opposed to the direction of rotation of the first bending arm (2), and each of the two bending arms (2, 3) can be moved parallel to one another and perpendicular to the advancing direction of the tubes to be bent.
