    Abstract: A press for hot hydrostatic extrusion of a billet, has a stand, a pressure chamber axially movable in the stand to engage a die mounted in one end against a die support carried by the stand, a punch slidable in the pressure chamber to raise a pressure medium in the pressure chamber to extrusion pressure, and a billet holder slidable in the chamber for pressing the billet against the die during sliding movement of the pressure chamber to closing position. In order to prevent contact between the die support and the die until extrusion is about to begin, with consequent cooling of the billet which interferes with the extrusion, an annular canted spring is arranged in a groove in the face of the die support opposite the die so as to prevent contact therebetween during closing movement of the pressure chamber.

    Abstract: In the hydrostatic extrusion of compound billets, in which the billet is formed of a core of one material and a casing surrounding the core of another material, and in which a gap is left during the assembly of the billet to allow for deformation of the casing, the core is provided with a point and the casing has an inwardly directed conical flange within which the point of the core rests. At the back end, the core is provided with a sealing device for preventing the entry of fluid into the space between the core and the casing. In order to prevent the compression of the air in the space between the core and the casing, the core is provided at its front end with passages which open into the point of the core and which communicate with the space between the core and the casing, providing an air escape arrangement.

    Abstract: IN HYDROSTATIC EXTRUSION OF A WIRE OR ROD CONSTITUTED BY A CASING OF ONE MATERIAL AND A CORE OF ANOTHER, USUALLY A SOFTER MATERIAL, A BILLET IS EXTRUDED THROUGH A DIE FROM A PRESSURE CHAMBER PROVIDED WITH A CONICAL SURFACE, ADJACENT THE DIE OPENING, THE BILLET IS SO CONSTRUCTED THAT THE AXIAL FORCES CREATED BY THE DIFFERENCES IN MOLDING RESISTANCE OF THE DIFFERENT MATERIALS ARE TRANSFERRED BETWEEN THE CASING AND THE CORE. THIS IS DONE BY PRESSING THE REAR END OF THE CASING INTO A GROOVE IN THE CORE.

    THE JOINT BETWEEN THE CASING AND CORE IS SEALED AT THE REAR ENDS. THE FRONT END OF THE CORE IS SHAPED TO MATCH THE CONICAL SURFACE OF THE DIE, AND THE CASING MAY BE BROUGHT DOWN OVER THIS FRONT END, THE FRONT END OF THE CASING TAPERING IN THICKNESS. SUCCESSIVE CASING AND CORES MAY BE JOINED ONTO THE REMAINING PARTS OF CASINGS AND CORES OF A PREVIOUS BILLET WHICH HAS BEEN LARGELY EXTRUDED.

    Abstract: For hydrostatic extrusion, a press is provided having a yoke. One of the end pieces of the yoke carries a die receiving block having an extrusion passage therethrough. A pressure cylinder is mounted within the yoke for movement towards and from the die receiving block. Slidable in the cylinder of the high pressure cylinder is a billet holder which divides the space within the cylinder into two parts. The billet holder has a spring controlled valve which prevents passage of pressure fluid therethrough until a predetermined pressure differential exists between the chambers. A punch is provided for sliding into and out of the high pressure cylinder on the opposite side thereof from the die. The die and billet are first positioned between the high pressure cylinder and the die receiving block, after which the high pressure cylinder is moved to enclose the billet. Then pressure is applied in the high pressure cylinder on the side of the punch to move the billet holder against the billet and move the billet into engagement with the die. Then the pressure behind the the billet holder is increased so that the fluid passes through the billet holder and thereafter further increased by advancing the punch into the high pressure cylinder so that the fluid exerts sufficient pressure on the billet to extrude it. Before opening the high pressure cylinder, the punch is withdrawn and cool pressure fluid is admitted into the end of the cylinder remote from the punch.

    Abstract: In hydrostatic extrusion of a wire or rod of one metal with a casing of another metal, a billet is extruded through a die from a pressure chamber provided with a conical surface adjacent the die opening. The billet is so constructed that fluid is prevented from entering between the core and the casing and that the axial forces created by the differences in moulding resistance of the different materials are transferred between the casing and the core. This may be done by providing a member which overlies the rear ends of the casing and core. The joint between the casing and core is sealed at the rear ends. The front end of the core is shaped to match the conical surface of the die, and the casing may be brought down over this front end, the front end of the casing tapering in thickness.

    Abstract: RODS OR WIRE ARE PRODUCED FROM POWDER BY FORMING A BILLET COMPACTED TO GREAT DENSITY AND PROVIDED ON ITS SURFACE WITH A TEMPORARY, LIQUID-TIGHT BARRIER OF NONMETALLIC YIELDING MATERIAL. THE BILLET IS ENCLOSED IN A PRESSURE CHAMBER LOCATED ABOVE A DIE, WITHIN WHICH CHAMBER A LIQUID CAN BE COMPRESSED. THE COLD BILLET IS FORMED BY HYDROSTATIC EXTRUSION TO A CROSS SECTION DETERMINED BY THE NOZZLE OF THE DIE AFTER WHICH THE TEMPORARY BARRIER IS REMOVED. THE DEFORMATION IS CARRIED OUT UNDER SUCH PRESSURE AS TO PRODUCE A SUFFICIENT INCREASE IN TEMPERATURE TO SINTER THE POWDER.
