Abstract

The blank (11) enters an elongate channel (18) ending in an extrusion chamber (19) located immediately upstream of a die (20). The channel (18) is formed by a groove (incision) (13) cut in the rotor (10) and by an end part at the entry of which the groove (incision) (13) is closed off, in a manner which is leaktight with respect to the extrusion fluid, by a relief (17) of the stator (16). The extrusion fluid is introduced, at the extrusion pressure, into a concentric zone (14) of the channel (18) by means of a nozzle (15). This device makes it possible to effect the hydrostatic extrusion of a metal blank, even one with low ductility, or, alternatively, of a blank made from synthetic resin, with a very high entrainment force, using a small-diameter rotor. <IMAGE> [CH617604A5]
