Abstract

SE PROPONE UN PROCEDIMIENTO PARA LA PRODUCCION DE UN BOQUETE EN LA PARED DE UNA PIEZA (1) CONFORMADA COMO CUERPO HUECO, EN EL QUE SE APLICARA LA PIEZA (1) EN UNA HERRAMIENTA PERFILADA (2) DELIMITANDO SU EXTENSION RADIAL , LA CUAL ES DOTADA EN LA ZONA DEL BOQUETE PREVISTO CON UNA FORMACION (6) CON UN CONTORNO CORRESPONDIENTE AL BOQUETE. POSTERIORMENTE EL ESPACIO HUECO (3) DE LA PIEZA (1) ES IMPULSADO CON UN MEDIO ACTIVO HASTA UNA PRESION INTERNA PI PRODUCIENDO EL ENTALLADO DE LA PARED DE LA PIEZA A LO LARGO DE UN CANTO (10) DE LA FORMACION (6). ESTO OCURRE EN PARTE DURANTE UNA TRANSFORMACION ADICIONAL DE LA PIEZA (1) BAJO LA APLICACION DE UN PROCESO DE TRANSFORMACION POR ALTA PRESION INTERNA.A PROCEDURE IS PROPOSED FOR THE PRODUCTION OF A GAP IN THE WALL OF A PART (1) CONFORMED AS A HOLLOW BODY, IN WHICH THE PART (1) IS APPLIED IN A PROFILED TOOL (2) LIMITING ITS RADIAL EXTENSION, WHICH IS GIVEN IN THE GAP AREA PROVIDED WITH A FORMATION (6) WITH A CONTOUR CORRESPONDING TO THE GAP. SUBSEQUENTLY THE HOLLOW SPACE (3) OF THE PIECE (1) IS PROMOTED WITH AN ACTIVE MEDIA UP TO AN INTERNAL PRESSURE PI PRODUCING THE FITTING OF THE WALL OF THE PIECE ALONG A EDGE (10) OF THE FORMATION (6). THIS HAPPENS IN PART DURING AN ADDITIONAL TRANSFORMATION OF THE PART (1) UNDER THE APPLICATION OF A PROCESS OF TRANSFORMATION BY HIGH INTERNAL PRESSURE.
