Abstract:
A swaging machine for swaging rod-shaped or tubular workpieces, which comprises(a) a machine frame,(b) a forging box rotatably mounted in the machine frame to be driven about an axis of movement of the workpiece through the forging box,(c) forging punches mounted in radial recesses of the forging box, the forging punches acting against each other and being radially movable towards the axis of movement of the workpiece by a drive while the forging box is driven about the axis of movement, each forging punch comprising(1) a first part adjacent the drive and rotatably guided in the forging box, and(2) a second part adjacent the axis of movement of the workpiece and non-rotatably guided in the forging box, the first and second forging punch parts being screwed together, and(d) a transmission connected to the first forging punch part, the transmission including(1) a gear rim non-rotatably but axially movably seated on the first forging punch part and rotatably but axially immovably mounted in the forging box, and(2) a drive gear rotatably mounted in the forging box, the drive gears of the transmissions connected to the first parts of the forging punches forming part of a planetary gear system.
