Abstract

LA INVENCION SE REFIERE A UNA HERRAMIENTA INSERTABLE FLEXIBLE PARA MOLDEADO INTERNO DE ALTA PRESION Y ENCUENTRA SU APLICACION ESPECIALMENTE EN EL MECANIZADO DE PLETINAS DE CHAPA SIMPLES O DOBLES. YA SE CONOCEN UNA MULTITUD DE SOLUCIONES PARA EL MOLDEADO INTERNO DE ALTA PRESION DE CUERPOS HUECOS DE REVOLUCION DE DOS CHAPAS UNIDAS ENTRE SI EN SUS LADOS. LA DESVENTAJA DE ESTOS PROCESOS ES QUE CON LAS HERRAMIENTAS CONOCIDAS SOLO SE PUEDE REALIZAR UNA VARIANTE DEL PROCESO. DE ACUERDO CON EL PROBLEMA SE DESARROLLO UNA HERRAMIENTA EN LA CUAL LA PARTE SUPERIOR DE LA HERRAMIENTA (1) SE PUEDEN COLOCAR ELEMENTOS DE HERRAMIENTA SELECCIONABLES EN FORMA DE UN MACHO (7) DESPLAZABLE AXIALMENTE O DE MATRIZ (6). EN LA ZONA INFERIOR DE LA HERRAMIENTA (2) SE ENCUENTRA UNA CAMARA DE ALTA PRESION (4), QUE ESTA UNIDA A UN ELEVADOR DE PRESION DEL SISTEMA DE ALTA PRESION A TRAVES DE UN TALADRO DE ALTA PRESION (5), DE FORMA QUE LA CHAPA (3) COLOCADA ENTRE LA PARTE INFERIOR DE LA HERRAMIENTA (2) Y LA PARTE SUPERIOR DE LA HERRAMIENTA (1) SE MOLDEA O TALADRA RESPONDIENDO A LA SELECCION Y CONSTRUCCION DE LOS ELEMENTOS DE LA HERRAMIENTA EN FORMA DE MACHO (7) O MATRIZ (6), AL APORTARSE LOCALIZADAMENTE LA PRESION EN LA CAMARA DE ALTA PRESION (4). SEGUN LOS REQUERIMIENTOS EL MACHO (7) PUEDE CONSTRUIRSE COMO MACHO DE CORTE, DE MOLDEO O COMO EYECTOR.
