Abstract

A bending machine for bending elongated workpieces supplied from a magazine is disclosed. The bending machine comprises a base support; two bending robots arranged on a common guideway centrally mounted to the base support, such that the robots are displaceable parallel to the longitudinal direction of the base support. A holding clamp is positioned on the front face of the base support, with one auxiliary gripper on either side of the holding clamp. The holding clamp is displaceable in parallel with the bending robots. A discharge gripper is positioned on the rear surface of the base support, laterally offset with respect to the holding clamp.All grippers and clamps are pivotable to an inner pivoting position, in which they can hold a workpiece in the working area of the bending machine between both bending robots; and to an outer pivoting position away from the base support.
