Abstract

LA INVENCION ESTA RELACIONADA CON UN METODO PARA REALIZAR UN CICLO DE EXPULSION DEL AIRE ATRAPADO ENTRE UN TOCHO CILINDRICO Y UN TROQUEL EN UNA PRENSA DE EXTRUSION GENERICA DE METALES (1) QUE COMPRENDE UN PORTADOR (5) PARA UN TOCHO CILINDRICO (B) Y UN EMBOLO (2) SUMINISTRADO CON LOS RESPECTIVOS CONJUNTOS DE PISTON/CILINDRO HIDRAULICOS DE ACTUACION (6; 3 Y 4). PARA LLEVAR A CABO EL METODO, SE SUMINISTRA LA PRENSA (1) CON ACUMULADORES HIDRONEUMATICOS (11, 15) ADAPTADOS PARA SUMINISTRAR A LOS CONJUNTOS DE PISTON/CILINDRO (4 Y 6) ACEITE A UNA PRESION TAL QUE RESISTAN LAS FUERZAS DE EMPUJE DEL PORTADOR (5) RESPECTO AL TROQUEL DE EXTRUSION (M) Y DEL EMBOLO (2) RESPECTO AL TOCHO CILINDRICO (B) A MEDIDA QUE ESTE ULTIMO SE EXTRUYE.THE INVENTION IS RELATED TO A METHOD FOR PERFORMING AN EXPULSION CYCLE OF TRAPPED AIR BETWEEN A CYLINDRICAL STOCK AND A DIE IN A GENERIC METAL EXTRUSION PRESS (1) INCLUDING A CARRIER (5) FOR A CYLINDRICAL STACK (B) AND A PLATE (2) SUPPLIED WITH THE RESPECTIVE HYDRAULIC ACTUATION PISTON / CYLINDER ASSEMBLIES (6; 3 AND 4). TO CARRY OUT THE METHOD, THE PRESS (1) IS SUPPLIED WITH HYDRO-PNEUMATIC ACCUMULATORS (11, 15) ADAPTED TO SUPPLY THE PISTON / CYLINDER ASSEMBLIES (4 AND 6) OIL AT A PRESSURE SUCH AS THE RESISTANT PUSHING FORCES (5) REGARDING THE EXTRUSION DIE (M) AND THE PIT (2) REGARDING THE CYLINDRICAL STOCK (B) AS IT LAST IS EXTRUDED.
