Abstract

UN PROCEDIMIENTO DE FUSION DE METALES PARA LA OBTENCION DE NUCLEOS METALICOS DE FUSION Y SIMILARES, HECHOS DE ALEACIONES METALICAS CON TEMPERATURAS BAJAS DE FUSION, CONSIGUE UNA FUSION CON DENSIDAD UNIFORME, ACABADO DE GRAN CALIDAD Y UNA ESTRUCTURA DE GRANO FINO. EL PROCEDIMIENTO Y EL APARATO NO REQUIEREN LA DESPRESURIZACION DE UN CILINDRO DE CARGA, Y PERMITE LA UTILIZACION DE ESTAMPAS CERRADAS. EL APARATO COMPRENDE UN DEPOSITO (10) DE ALEACION DE METAL FUNDIDO, UN CILINDRO (14) EN EL DEPOSITO (10), QUE TIENE EN SU BASE UNA CONEXION A UN PASILLO (22) QUE CONDUCE A TRAVES DEL DEPOSITO) A UNA ESTAMPA (32) SITUADA FUERA DEL DEPOSITO (10). EN EL PASILLO (22) HAY UNA VALVULA (18), EN EL DEPOSITO (10), TENIENDO UNA PRIMERA POSICION DONDE EL PASILLO (22) A LA ESTAMPA (32) ESTA ABIERTO, Y UNA SEGUNDA POSICION DONDE EL PASILLO (22) A LA ESTAMPA (32) ESTA CERRADO. EN LA SEGUNDA POSICION, UNA LUMBRERA DE LA VALVULA (64) PROPORCIONA UNA CONEXION DESDE EL CILINDRO (14) A LA ALEACION (12) DE METAL FUNDIDO, EN EL DEPOSITO (10). UNA SERVOVALVULA (52) MUEVE LA VALVULA (18) DESDE LA PRIMERA POSICION A LA SEGUNDA, UN PISTON (30) DENTRO DEL CILINDRO (14) Y UN SISTEMA DE ENERGIA ELEVA EL PISTON (30) EN EL CILINDRO (14) CON LA VALVULA (18) EN LA SEGUNDA POSICION PARA LLENAR EL CILINDRO (14) CON ALEACION (12) DE METAL FUNDIDO Y BAJAR EL PISTON (14) CON LA VALVULA (18) EN LA PRIMERA POSICION PARA INYECTAR METAL (12) FUNDIDO DENTRO DE LA ESTAMPA (32). EN UNA VERSION PREFERENTE, UNA SEGUNDA VALVULA (26) ESTA SITUADA FUERA DEL DEPOSITO (10) Y EN EL PASILLO (22) QUE VA A LA ESTAMPA (32). LA SEGUNDA VALVULA (26) ACTUA JUNTAMENTE CON LA PRIMERA VALVULA (18) EN LA PRIMERA POSICION PARA PERMITIR LA INYECCION DE ALEACION (12) DE METAL FUNDIDO DENTRO DE LA ESTAMPA (32).
