Abstract
Forging machines are provided with four rams which are arranged offset at 90.degree. to one another in a cruciform manner in one plane acting radially upon the workpiece guided longitudinally in the system axis and are equipped with tools, wherein displacement devices acting upon tool supports are provided for setting the tools with respect to the rams in accordance with the end position of the stroke of the rams. The known displacement devices have the disadvantage that the connection of the displacement devices to their drives must be provided with couplings or transmission connections which compensate the stroke of the rams. By the present invention the drives of the displacement devices are secured to the rams and push-pull rods or rotating rods are provided as drive connections with the displacement devices mounted on the front plates of the rams, for the transverse displacement of the tools. In particular, linear-stroke drives are provided which cooperate with push-pull rods as drive connections and angle-lever drives as displacement devices.
