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： 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.

摘要： Disclosed is a method and apparatus for cold-working annular workpieces by applying thereto an internal fluid pressure to cause an enlargement of the diameter thereof through plastic deformation, in which the openings at opposite ends of an annular workpiece are closed by a pair of presser plates through packings which are radially expansible along with the annular workpiece. The contacting surface pressure of the packings and presser plates are controlled to a predetermined value by an arithmetic unit operating on detected values of a main pressure acting internally on the annular workpiece, an auxiliary pressure pressingly holding the presser plates against the respective packings and varitions in the shape of the annular workpiece undergoing the plastic deformation.
