Abstract:
A machine for bending an elongated workpiece, comprising:a) a bed having a body portion extending along a longitudinal axis, and a head portion extending along a transverse axis perpendicular to the longitudinal axis; b) a pair of longitudinal guides on the body portion in parallelism with the longitudinal axis; c) a pair of transverse guides on the head portion in parallelism with the transverse axis; d) a body carriage for holding the workpiece and mounted on the longitudinal guides for movement along the longitudinal axis; e) a head carriage mounted on the transverse guides for movement along the transverse axis; f) a workpiece bending assembly mounted on the head carriage for joint movement therewith along the transverse axis, the assembly including an elongated shaft, a pair of bending dies at opposite end regions of the shaft, and a pair of bending arms each operative for bending the workpiece against a respective bending die; and g) a drive for turning the bending assembly about a turning axis parallel to the longitudinal axis to position a selected one of the bending dies against the workpiece to be bent, the turning drive being mounted on the head carriage so that the turning drive can be moved along the transverse axis with the head carriage.
