ABSTRACT:
A swaging machine (1) for swaging rod-shaped workpieces (W) has a ring-shaped forging box (3) supported in a machine frame (2) so as to be driven and rotated about the travel axis (A) of the workpiece (W), where in radial recesses (4) of the forging box forging punches (5) are accommodated which act against each other and can be lifted via a lifting drive (7) while the forging box rotates at the same time. To ensure swaging with a non-rotating workpiece (W) subjected to a pure longitudinal feed, the forging punches (5) are supported in the recesses (4) of the forging box (3) via pivotally mounted longitudinal guideways (13), and oscillating movements with a direction of movement lying in a normal plane (N) with respect to the travel axis (A) can be superimposed on the lifting movements of the forging punches (5) for swinging back the associated forging tools (6) relative to the forging box (13) during their contact with the workpiece at an angular velocity corresponding to the angular velocity of the rotation of the forging box, but directed in the opposite direction.
