  • Patent number: 8404997
    Abstract: A mechanical arrangement (1) for processing rod-like workpieces, especially pipes (2), has a processing device (20) for processing a workpiece, a workpiece-moving device (6) for moving workpieces (2) relative to the processing device (20), and a device (11) for supporting a workpiece in the direction of gravity. The device (11) for supporting a workpiece includes at least one support roller (13) which forms at its outer periphery a workpiece rest. The workpiece rest at the outer periphery of the support roller (13) extends about a roller rotation axis (14) of the support roller (13) at a changing center distance. The support roller (13) is rotatable about the roller rotation axis (14) in a controlled manner and is thereby positionable in different rotational positions.

  • Patent number: 7237419
    Abstract: A bending tool (12) for bending workpieces, especially plate and sheet metal blanks includes at least one bending element (23) positioned on one side of a workpiece as well as a retainer device with clamping elements (14, 42) on opposite sides of the workpiece. For bending the workpiece, the retainer is moved, together with the workpiece clamped on it, relative to a bending element (23). In the process, the retainer device with the workpiece and the bending element (23) move relative to each other in a bending stroke which contains a component in the bending-stroke direction as well as a component in the transverse direction of the bending stroke. The direction of the bending stroke is controlled by at least one control element associated with the bending element (23) as well as at least one guide element associated with the equal-sided clamping element (42).
