Abstract

PROCEDIMIENTO DE FABRICACION DE UN TUBULAR DE EXPULSION PARA MOLDES. EL PROCEDIMIENTO PARA OBTENER TUBULARES DE EXPULSION EN LOS QUE SE GUIAN LOS CORRESPONDIENTES EXPULSORES UTILIZADOS EN MOLDES, POR EJEMPLO DE INYECCION, COMPRENDE UNA SERIE DE FASES OPERATIVAS QUE SE REALIZAN SOBRE UN TUBO (1) DEL QUE SE PARTE, CONSISTIENDO LAS FASES EN EFECTUAR PRIMERAMENTE UN CORTADO DE UNA PORCION DE TUBO (1) AL LARGO DESEADO, CON UN EXCESO DE DIAMETRO PARA POSIBILITAR UN POSTERIOR RECTIFICADO. EN UNA SEGUNDA FASE SE REALIZA UNA REDUCCION DE DIAMETRO EN UNA ZONA EXTREMA (2), PARA EFECTUAR EN UNA TERCERA FASE UN PRERECTIFICADO EXTERIOR (3), EFECTUANDO EN UNA CUARTA FASE UN MECANIZADO INTERIOR DE LA ZONA EXTREMA (2) CON UNA CONCENTRICIDAD TOTAL. EN UNA QUINTA FASE SE EFECTUA UN TEMPLADO POR INDUCCION Y SEGUIDAMENTE, SEGUN UNA FASE SEXTA, SE EFECTUA UN RECTIFICADO EXTERIOR PARA OBTENER EL DIAMETRO EXTERNO DESEADO, REALIZANDO EN UNA SEPTIMA FASE UN RECTIFICADO INTERIOR SOBRE EL DIAMETRO INTERNO DE LA ZONA (2), PARA FINALMENTE EN UNA OCTAVA FASE REALIZAR UN REFRENTADO FRONTAL (6) OBTENIENDOSE ASI UN TUBULAR (1) DE EXPULSION PARA MOLDES EN GENERAL. OPCIONALMENTE PUEDE OBTENERSE UNA CABEZA RECALCADA EN EL EXTREMO POSTERIOR DEL TUBULAR (1).
