摘要： Method of plastically deforming a body of malleable solid material between male and female dies which are forcible pressed together. The material is subjected to repeated identical pressing cycles; in each pressing cycle the force between the dies is concentrated consecutively on separate sections of the surface of the material being deformed. The body may be directly or indirectly extruded into an elongated shape from a location between the male and female dies which is disposed nearest the section of the surface of the material being deformed in each pressing cycle, or it may be deformed between the dies without any appreciable portion thereof escaping from between the dies.

摘要： In a modified "Conform" machine for continuous friction-actuated extrusion of metals, especially particulate copper, the abutment at the outlet end of the working passageway does not fully block the end of the wheel groove. Instead a substantial clearance is left, and metal extruding through it adheres to the wheel to re-enter the working passageway at the entry end. Preferably the abutment is of semicircular cross-section. For a given output rate, a significant reduction in torque, and working stresses, is obtained.

摘要： Two elongated gripping members (12,12) cooperate to form a closed pressure chamber about a waxed billet (61). The gripping members are reciprocated relative to an extrusion station (13), such reciprocation first moving the pressure chamber toward and past the extrusion station so as to extrude the billet through a die (66) at the extrusion station, and then returning the gripping members, in separated condition, to their initial positions to permit the immediate loading of another billet between the gripping members. Also disclosed are various additional systems, e.g., for feeding billets between the gripping members from a magazine; for coating the billets with wax; for automatically changing dies at the extrusion station; for providing soft, dummy billets to facilitate the complete extrusion of each successive billet, and to serve as soft, starting noses as each successive extrusion operation begins; for applying, along exterior surfaces of the gripping members, a pressure gradient increasing in the direction of the extrusion station, to match increasing pressure levels within each waxed billet during extrusion; and for so stressing and/or prestressing certain structural elements as to oppose high, extrusion-caused stresses.

摘要： Apparatus for extrusion forging essentially comprises a double action hydraulic press composed of an inner ram. Extrusion forging of a billet is accomplished by placing the billet in a container and inserting a punch into the container thereby forcing the billet through the die. After the extrusion forging, the punch is raised to a prescribed level and held there and the container is subsequently raised. Since the undeformed part of the billet is attached fast to the container, the rising container drags the extruded part of the billet out of the die and, at the same time, brings the undeformed part of the billet into powerful collision with the punch and consequently knocks the extrusion forged product out of the container.
摘要翻译：用于挤压锻造的装置基本上包括由内压头构成的双作用液压机。通过将坯料放置在容器中并将冲头插入容器中从而迫使坯料穿过模具来实现坯料的挤压锻造。在挤出锻造之后，将冲头升高到规定的水平并保持在那里并随后使容器升高。由于坯料的未变形部分快速附着在容器上，所以上升的容器将坯料的挤出部分从模具中挤出，同时使坯料的未变形的部分与冲头发生强烈的碰撞，因此将挤出的锻造产品从容器中挤出。

摘要： A device for manufacturing, by extrusion, a piece having a recessed portion in its lateral surface, and, on one side, a head and, on the opposite side, a tail, which device comprises a fixed die holder containing a die, a punch borne by a mobile support and structure for axially displacing the punch to engage it in the die and to disengage it therefrom together with means for ejecting the extruded piece. The device further comprises, in front of the fixed die holder, a coaxial mobile die holder composed of two parts, forming clamp. A spring and cooperating cams are provided for opening and closing the mobile die holder-forming clamp and an actuator is provided for displacing the mobile die holder in translation parallel to the axis of the punch and of the die. After the actual extrusion operation, the mobile die holder-forming clamp draws on the head of the extruded piece so as partially or totally to disengage its tail from the die, then the mobile die holder is opened so as to release the piece and allow ejection thereof.
