A bending assembly on a bending machine for the bending of rod and/or bar-shaped workpieces (8) includes a bending tool (10) and a bending drive unit (11) with a swivel arm (21) and a bending-drive motor (22). The bending tool (10) has at least one workpiece thrust block (12, 13), and the swivel arm (21) has at least one thrust pad (17, 18). The bending-drive motor (22) rotates the swivel arm (21) with the thrust pad (17, 18) around a bending axis (14) that extends in the transverse direction of the workpiece. The workpiece is bent when the thrust pad (17, 18) forces it against and around the associated workpiece thrust block (12, 13). The shaft of the bending drive motor (22) extends parallel to the bending axis (14), and both ends of the shaft are drive-connected to the swivel arm (21).
A bending assembly in a bending machine (1) for bending elongated rod and bar-shaped workpieces (8) comprising (a) a bending tool (10) and (b) a bending drive unit (11) including (c) a swivel arm (21) and (ii) a bending-drive motor (22), said bending tool (10) including (i) at least one workpiece thrust block (12, 13) and (ii) at least one thrust pad (17, 18) on the swivel arm (21), said bending-drive motor (22) being operable to rotate the swivel arm (21) with the thrust pad (17, 18) around a bending axis (14) extending in a direction transversely of the elongated workpiece, whereby the workpiece, forced by the thrust pad (17, 18) against the associated workpiece thrust block (12, 13), can be bent by rotating the swivel arm (21) with the thrust pad (17, 18) around the workpiece thrust block (12, 13), said bending-drive motor (22) having a motor shaft (27) which extends parallel to the bending axis (14) and is drive-connected at both shaft ends (28, 29) to the swivel arm (21).
