Abstract

EN LA TRANSFORMACION APOYADA MEDIANTE PRESION INTERNA DESCRITA DE PERFILES HUECOS PARA PIEZAS (1) DE TRABAJO PROVISTAS CON BIFURCACIONES O SIMILARES (12) SE APLICA EL INTERIOR DE UNA PIEZA CRUDA APLICADA EN UNA HERRAMIENTA (2), QUE SE ENCUENTRA EN ENGRANE CON AMBAS CARAS FRONTALES CON PUNZONES (3,4) DE PRESIONADO MOVILES, GUIANDO UN MEDIO A PRESION LIQUIDO, Y LA PIEZA EN BRUTO SE PRESIONA CON LA AYUDA DE UN PUNZON DE PRESIONADO BAJO ABOMBADO EN AL MENOS UN ESPACIO (7) HUECO EN LA HERRAMIENTA (2). CON ELLO SE CONECTA LA PRESION (PI) DEL MEDIO A PRESION EN EL INTERIOR A TRAVES DE LOS PUNZONES (3,4) DE PRESIONADO, ANTES DEL PROCESO DE PRESIONADO DE LA PIEZA CRUDA TRATADA EN CALIENTE EN DEPENDENCIA DEL PROGRESO DEL PROCESO CONTROLADO MEDIANTE PRESION. EN LAS FASES DEL PROCESO SE AJUSTAN LAS DILATACIONES PEQUEÑAS DEL MATERIAL DE TRABAJO-PIEZA CRUDA CON LA PRESION (PI) DE TAL MODO, QUE SE CONSIGUE DE FORMA ESENCIALMENTE EXACTA LA RESISTENCIA DE MODIFICACION DE LA FORMA DEL MATERIAL DE TRABAJO, ELEVANDOSE LAS FASES DEL PROCESO CON GRANDES DILATACIONES DE LA PRESION (PI) PARA CONSEGUIR SUFICIENTEMENTE LA DILATACION DE ROTURA DEL MATERIAL DE TRABAJO.
