ABSTRACT:
Known swaging machines comprise swaging rams extending in a swaging box in a radial direction with respect to the path for the workpiece and carry swaging dies at their inner ends. To enable swaging rams of small dimensions and a compact structure to be used while avoiding sealing problems, the swaging rams have an elliptical cross section, with a major axis extending parallel to the workpiece path.
