ABSTRACT:
A forging machine having rams arranged in the form of a cross carry respective tools adjustable transversely to the ram axes and partly overlapping one another, so that a closed pass can be formed for any size of the forging pass. To adjust the tools transversely, each tool is carried on a respective crosspiece which can be clamped against the ram end or can be released and moved transversely on the ram. The clamping and releasing and the adjustment movement are all effected by a rotary tie rod extending through the crosspiece and through the ram, having one end coupled to the crosspiece for clamping it and moving it transversely to the ram, and the other end coupled to a clamping mechanism and to a rotary adjustment drive.
