ABSTRACT:
A bending machine for the bending of rod-shaped and/or bar-shaped workpieces and especially of pipes incorporates a bending device (5) with bending tools (10, 11) that are provided on both sides of a tool platen (12). These bending tools (10, 11) include in each case a bending swage (13, 16) and at least one thrust member. At least one thrust member on one side of the tool platen and at least one thrust member on the other side of the tool platen (12) are drivingly coupled for joint movement in the transverse direction of the workpiece, with the movement in the transverse direction of the workpiece for shifting the thrust member(s) on one side of the tool platen (12) into its or their operating position permitting movement of the associated thrust member(s) on the other side of the tool platen (12) in the opposite direction. As an alternative or in addition, the thrust members are in the form of slide rails (15, 18), drivingly coupled on both sides of the tool platen (12) for movement in the longitudinal direction of the workpiece.
