Patent ID: 8613212

Claim:
Extruding press comprising: a die platen element with at least one extrusion matrix for producing an extruded product along a longitudinal direction; a main cylinder with a relative pressing shank for billets made of manufacturing material; longitudinal columns connecting said die platen element to said main cylinder; a multiple equipment assembly provided with at least two longitudinal containers for housing said billets, and comprising an external, longitudinally moving, cross element and an internal ram inside said external cross element, said internal ram being transversally movable with respect to said longitudinal direction and comprising said at least two longitudinal containers; means for longitudinally moving said multiple equipment assembly, adapted to tightly close a first longitudinal container of said at least two longitudinal containers with said extrusion matrix; means for transversally moving said internal ram, adapted to make said first longitudinal container face said extrusion matrix for an extrusion of a first billet, and also adapted to make at least one second longitudinal container of said at least two longitudinal containers face means for a loading of a second billet simultaneously with the extrusion of the first billet; wherein said means for longitudinally moving said multiple equipment assembly comprise pairs of control cylinders facing and being opposite one another, said pairs of control cylinders being placed on two opposite external sides of the external cross element, wherein said control cylinders are provided with double and closed chambers for respective pistons, said chambers being externally fastened on said external cross element, and are provided with respective shanks, wherein first control cylinders of said pairs of control cylinders, having a first shank facing the die platen element, have said first shank abutting on said die platen element, while second control cylinders of said pairs of control cylinders, opposed to said first control cylinders and having a second shank facing the main cylinder, have said second shank fastened on said longitudinal columns.
