ABSTRACT:
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).
