Abstract: A device and method for bending strand-shaped workpieces are described with a holder for a strand-shaped workpiece. A bending tool comprises at least one radius part and one bending part. The workpiece can be bent by pivoting the bending part about the radius part. A workpiece drive shaft that extends at least in a longitudinal direction is provided for driving the bending tool and a positioning device for positioning the bending tool relative to the workpiece. The positioning device allows a displacement of the bending tool and the tool driveshaft in at least one transverse direction that runs transversely to the longitudinal direction. A drive wheel is rotatably arranged around an axis that is fixed relative to the workpiece and is coupled via a transmission device to drive the tool driveshaft. The transmission device has a coupling element that can move transverse to the axis of the drive wheel.

Abstract: A device for bending tubular workpieces includes a straight workpiece section that extends in a longitudinal direction and is held in a clamping device. A bending tool for bending the workpiece around a bending axis, running transversely to the longitudinal direction, has a radial part and a bending part. The radial part is rotatable about the bending axis. The bending part can be pivoted relative to the radial part for bending the workpiece about the bending axis. For rotatable driving, a radial driveshaft is coupled to the radial part, and a bending driveshaft is coupled to the bending part. To very flexibly create a plurality of different bends and to be able to use variable bend geometries, the radial driveshaft and the bending driveshaft extend in the longitudinal direction. The radial driveshaft and/or the bending driveshaft are designed as a hollow shaft, and one is arranged coaxially around the other.
