Abstract: A swaging machine comprises eccentric-driven swaging rams provided with a slide track extending transversely to the axis of the eccentric, and a slide block rotatably mounted on the eccentric and guided by said slide track as in a Scotch yoke. To provide a structure which is simple, inexpensive and light in weight, each swaging ram is coupled to the associated slide block at that end face of the swaging ram which is remote from the die. The slide track is formed by a head portion of the swaging ram and interengages with an associated guide rail of the slide block.
