摘要

An apparatus for bending pipes of large diameter by narrow bending radii, wherein– in this apparatus for bending a tube (2) in the axial direction by means of a this tube (2) annularly surrounds, inductively acting heating device is guided,– the tube (2) to be bent at its end by means of a receiving device (1) is enclosed, which is connected with a flexurally lock,– in the case of the in the direction of advance of the tube (2) that part of the apparatus for the bending at least one bending arm (4) is located, which is about a vertical axis of rotation (5) is rotatably mounted,– the bending lock indirectly to the bending arm (4) is connected,– the bending lock, a force transmitting device (3) between the receiving device for pipes (1) and the bending arm (4) comprises,– the force-transmitting device (3) with the bending arm (4) is adjustably connected in such a way that the distances between the center axis of the receiving device for pipes (1) and the vertical axis of rotation (5) between a minimum and a largest distance can be selected as a result of which is a range between a largest and a minimum bending radius (6) is adjustable,– the force-transmitting device (3) the bending forces on the axis of rotation (5) side facing away from the receiving device (1) and on its underside on the bending arm (4) which initiates,characterized in that the force transmission device (3) is designed as a closed frame, on the outside of the receiving device for pipes (1) is fastened.
