摘要： A hydrostatic extrusion method and apparatus for the extrusion of tubes is disclosed wherein the simplified structure of the nose or tip portion of the billet and the cooperating surfaces of the die defining the die cavity and those of the mandrel facilitate an improved initial sealing among the associated surfaces of the die, billet and mandrel. Such an initial sealing is effected between such interfaces of the members and billet at a point which is located substantially rearwardly from the position at which the actual extrusion to the final tubular configuration occurs between the bearing portion of the die and the cooperating sizing portion of the mandrel. Such structure and method permits the extrusion of tubes having walls of asymmetric or non-circular configurations in cross section, even those of complex configurations. In order to further enhance the efficacies of the present invention, the mandrel is provided with a head portion which may be replaced, or exchanged as desired, and a position-aligning member is associated with the mandrel in order to maintain the proper orientation of the mandrel relative to the die. The mandrel may also have a specifically designed configuration in order to provide the inner surface of the tube extruded with a gloss finish.

摘要： A method and machine for use in hydrostatic extrusion wherein a portion of an elastic-plastic viscous pressure medium is introduced into the rear portion of a container, with the rear end thereof being sealed in a fluid tight fashion. The pressure medium being of such a nature that it has a high viscosity and cannot flow by itself. Subsequently, a billet is charged into the container and then a die is mounted in the container at the forward end thereof. The aforesaid pressure medium is caused to fill around the outer circumferential surface of the billet. In this respect, a high pressure seal is provided for the junctions between the die and the forward end of the container and between the die and the forward end of the billet before the pressure medium flows out of the container in a practically negligible small amount, immediately after which a pressure stem is pushed into the container from the rear end thereof, thus proceeding with the hydrostatic extrusion.

摘要： There are disclosed herein a method and an apparatus for manufacturing tubes or tubular bodies by means of hydrostatic extrusion, which tubes or tubular bodies have axially running holes therethrough having cross-sections of irregular shapes. The method and apparatus utilize a mandrel of novel construction which comprises a conical tip portion having a smooth peripheral surface, a cut or grooved intermediate portion with a sloped groove starting at a peripheral edge and a body portion formed with a flange and adapted to move longitudinally of a pressure chamber, as necessary. The conical tip portion is specifically intended to seal against the conical end of a metallic billet. Unless there is such a provision, there would be leakage of a fluid through the grooved portion because of direct contact of the grooved edge with the inner end surface of the billet. Thus, this method and the apparatus for performing the method enables one-step extrusion of tubes or tubular bodies having inner fins or inner walls having irregularly shaped cross-sections, with the accompanying advantages of providing complete sealing among the die, the billet and the mandrel, particularly in the initial stage of the extrusion.

摘要： In the manufacture of compound billets composed of two or more different metals for use in hydrostatic extrusion, care must be exercised to see whether or not products possessing a predetermined compound status are produced from the compound billets by means of the hydrostatic extrusion process. The compound billets manufactured through the method of this invention do not, in the hydrostatic extrusion process, possess the usual defects caused by discrepancies between the mechanical properties of a plurality of different metallic materials constituting the billets, especially, and in particular, it is true that the compound billets are free from defects caused by surface slip taking place between the surfaces of the internal and external layer materials of the compound billet of the different metallic materials, and the method according to the present invention is characterized in that the formation of the nose part is undertaken by plastic forming of the same, such as roll forming and swazing, from the outside while maintaining an interior condition wherein air is expelled from the space formed between the contacting surfaces of the different metallic materials. As a result, the materials are mechanically bonded together and the surface areas of the materials of the billet at the deformed nose portion to be presented to the die are equal and it becomes possible to carry out a hydrostatic extrusion of the compound materials under a combination of different metallic materials covering an extremely wide selection.
