Abstract: A press for hydrostatic extrusion includes a press stand and a high pressure cylinder displaceable in the stand. A punch is mounted for movement into the high pressure cylinder to produce the extrusion pressure therein. The billet and die are positioned by a manipulating arrangement between the open end of the high pressure cylinder and a die support, and the cylinder is moved over the billet and die. Pressure fluid is then introduced through the die support and die into the pressure chamber, flow of the fluid out of the chamber being prevented by a valve arrangement or by seating of the billet against the die. The punch is then advanced into the pressure cylinder to produce extrusion.

Abstract: A press for the hydrostatic extrusion of long billets has a stand with a pressure generating chamber and a pressure generating plunger insertable in the pressure generating chamber to generate high pressure in a pressure medium contained therein. A pressure chamber is arranged in line and communicates with the pressure generating chamber. A stationary support table is provided to take up axial forces on a die, and is spaced from the opening of the pressure chamber so that a die can be inserted into alignment with the opening of the pressure chamber. The support table contains a piston which is movable in the direction of the pressure chamber and on which the die support is carried for movement of the die into the opening of the pressure chamber opening.
