Abstract
A device for bending a pipe includes a pipe feed device configured to continuously advance the pipe in a longitudinal direction of the pipe feed device; a bending arm pivotable about a rotation axis and having a pipe holding device securable on the bending arm in a first fixing position and in a second fixing position, the first fixing position disposed on the other side of a centre axis of the bending arm from the second fixing position, the pipe holding device configured to detachably secure the pipe, wherein the feed device and the bending arm are movable relative to one another such that the feed device and the rotation axis can be moved past one another; and a heating device disposed in a pipe feed direction and configured to heat an area of the pipe.

A device for bending a pipe comprising:
- a pipe feed device configured to continuously advance the pipe in a longitudinal direction of the pipe feed device;
- a bending arm pivotable about a rotation axis and having a pipe holding device securable on the bending arm in a first fixing position and in a second fixing position, the first fixing position disposed on the other side of a centre axis of the bending arm from the second fixing position, the pipe holding device configured to detachably secure the pipe, wherein the feed device and the bending arm are movable relative to one another such that the feed device and the rotation axis can be moved past one another;
- and
- a heating device disposed in a pipe feed direction and configured to heat an area of the pipe.
A bending arm for a device for bending a pipe comprising:
- a pivoting arm pivotable about a rotation axis and defining a centre axis running in a longitudinal direction of the pivoting arm;
- and
- at least one holding device disposed on the pivoting arm and configured to secure the pipe on the bending arm, wherein the at least one holding device is securable in a first and a second fixing position on the pivoting arm, the first fixing position disposed on the other side of a centre axis of the bending arm from the second fixing position.
A method for bending a pipe comprising:
- providing a bending arm disposed pivotally about a rotation axis and having a holding device for the pipe, wherein the pipe is detachably securable in the holding device, a feeding device configured to advance the pipe in a longitudinal direction, and a heating device configured to heat an area of the pipe;
- in a first step, bending the pipe in a first direction and releasing the pipe by the bending arm from the holding device from a first fixing position;
- in a second step, moving the feed device and the bending arm relative to one another so that the feed device and the rotation axis move past one another and securing the pipe on the holding device in a second fixing position on the bending arm, wherein the first fixing position is disposed on the other side of a centre axis of the bending arm from the second fixing position;
- and
- in a third step, bending the pipe in a second direction.
