The invention relates to a bend-straightening machine for long workpieces (7), said machine having workpiece holding fixtures (5) arranged on a machine table (3) to grip the ends of the workpiece (7) in a rotatable manner. The machine has at least two straightening bases (9) arranged a distance apart on the machine table for support of the workpiece in its longitudinal direction. At least one straightening ram (28) is provided between the straightening bases to act upon the workpiece. The straightening ram is mounted to an actuating mechanism which can be moved towards the workpiece and away from it by means of a driving mechanism (15). The invention provides for the actuating mechanism to be embodied as a bridge (17) which holds the straightening ram in the vertical alignment of the workpiece and which can be moved in a vertical plane by means of the drive mechanism. This design assures precise, directionally accurate straightening of the workpiece with a simple method of construction.
