Abstract
A swaging machine (,) for swaging rod-shaped or tubular workpieces is comprised of an annular forging box (,) mounted in a machine frame (,) so as to be rotated and driven about the axis of movement (A) of the workpiece, where in radial recesses (,) of said forging box forging punches (,) are accommodated, which are acting against each other and are vertically movable via a lifting drive (,) while the forging box rotates at the same time. To achieve an economic adjustment of the vertical position also during the forging operation, the forging punches comprise two parts screw-connected with each other, a drive-end, rotatably guided upper part (,) and a tool-end, non-rotatably guided lower part (,), where the upper part (,) has associated thereto a transmission (,) with a gear rim (,) non-rotatably, but axially movably seated at the upper part (,) and rotatably, but axially immovably mounted in the forging box (,), and a drive gear (,) rotatably mounted in the forging box (,), which drive gears (,) are part of a planetary gear system (,).
