Abstract
A forging press for producing flashless forgings from metal billets or pre-forms has a die-head (26) slidably mounted in a press-head (10) whereby it may retract into the press-head if a predetermined pressure on the die-head is reached or exceeded during the forging stroke. The die-head (26) is slidably mounted in a bore (30) containing hydraulic fluid and connected via conduits (38) and pressure relief valves (40) to a hydraulic reservoir (32). A die cavity for the billet or pre-form is defined between relatively movable die halves (16) and (18).
