Rotary swaging is an incremental forming process for the reduction of tubes and bars. Force transfer is radial.
Rotary swaging is an incremental metal forming process for the reduction of cross-sections of bars, tubes and wires. Sets of two, three, four or six dies perform small, high-frequency, simultaneous radial movements (oscillations). With every stroke of the die, a part of the workpiece is formed. Die movement is generated by means of cams. The kinematics are equivalent to those of an planetary gear. This is completely accessible, which makes it easy to carry out any maintenance work.
