Abstract

A swaging machine comprises at least four radial rams, which are angularly apart and axially guided in the machine frame and held against rotation. Each ram is associated with a power screw, to which an oscillating angular motion can be imparted preferably by a rocker lever and an eccentric shaft. Screw-threaded drive trains actuate said power screws so as to impart the reciprocating swaging motion to the rams and to adjust their position. To provide a structure which is as simple, compact and inexpensive as possible, each power screw has two screw-threaded portions. One screw-threaded portion is operatively connected to a swaging drive train and in threaded engagement with mating screw threads of the associated ram. The other screw-threaded portion is in screw-threaded engagement with a rotatable adjusting nut of an adjusting drive train.
