The forging press has a pump ram inserted into the upper part of a cylinder within a frame, and a press ram into the lower part. A cavity filled with working oil is provided between both parts of the cylinder for transmitting themechanically given reciprocting motion of the pump ram to the press ram. A stopper is provided outside the frame for machanically controlling the upper limit position in reciprocating motion of the press arm.
