Abstract

Il presente trovato si riferisce ad una pressa per l'estrusione di leghe non ferrose, che comprende un organo pressore provvisto, in corrispondenza di una sua estremità, di un mandrino pressatore che è affacciato ad una testa di estrusione. L'organo pressore è mobile a comando in avvicinamento o in allontanamento alla testa di estrusione per provocare l'estrusione, attraverso tale testa, di una billetta interposta tra il mandrino pressatore e la testa di estrusione. Nell'organo pressore, a partire dalla sua estremità rivolta verso la testa di estrusione, è definita una sede di alloggiamento del mandrino pressatore e tale mandrino è mobile relativamente all'organo pressore per l'alloggiamento, almeno parziale, del mandrino internamente all'organo pressore nella fase di allontanamento dell'organo pressore dalla testa di estrusione.The present invention relates to a press for the extrusion of non-ferrous alloys, which comprises a pressing member provided, at one of its ends, with a pressing mandrel which faces an extrusion head. The pressing member is movable with command towards or away from the extrusion head to cause the extrusion, through this head, of a billet interposed between the pressing mandrel and the extrusion head. In the pressing member, starting from its end facing the extrusion head, a seat for housing the pressing mandrel is defined and this mandrel is movable relative to the pressing member for housing, at least partially, the mandrel inside the member pressure in the phase of removal of the pressure member from the extrusion head.
