Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA EMBUTICION PROFUNDA HIDROMECANICA DE CHAPA (8) EN UN MOLDE PREFIJADO POR UN PUNZON (7) POR MEDIO DE UNA PRENSA (1), QUE CONTIENE EL PUNZON Y UNA CAMARA HERRAMIENTA (9) ABIERTA HACIA EL PUNZON QUE SE PUEDE CARGAR CON LIQUIDO, PARA LO CUAL UNA DE LAS DOS PARTES SE PUEDE ACCIONAR CON MOVIMIENTO DE CARRERA. LA CHAPA SE SUJETA POR SU BORDE EXTERIOR ENTRE UNA SUPERFICIE DE CONTACTO (5) EN LA CARA FRONTAL DEL PUNZON Y UNA SUPERFICIE DE CONTACTO OPUESTA (5) CONFORMADA CORRESPONDIENTEMENTE EN LA CARA FRONTAL DE LA CAMARA HERRAMIENTA ESTANCA A LIQUIDOS Y CON FUERZA CONTINUA. LA CAMARA HERRAMIENTA ESTA RELLENADA AMPLIAMENTE CON LIQUIDO QUE ESTA BAJO PRESION CRECIENTE, POR LO CUAL LA CHAPA SE DESPLAZA CON RESBALAMIENTO DE SU BORDE DESDE LA SUJECION PERIFERICA (5) ESTIRADA POR LA PRESION DEL LIQUIDO Y SE PRESIONA CON FIDELIDAD DE FORMA EN EL GRABADO DEL PUNZON. PARA ACORTAR EN EL TIEMPO LA FORMACION DE PRESION HASTA LA PRESION FINAL NECESARIA Y DESCARGAR LA PRENSA DE LAS FUERZAS MUY ELEVADAS, SE INTRODUCE EN LA CAMARA HERRAMIENTA UNA CARGA PROPULSORA DOSIFICADA, CON PREFERENCIA EN FORMA DE UN GAS COMBUSTIBLE (14) MEZCLADO CON OXIGENO (15), QUE SE ENCIENDE EN UN DETERMINADO MOMENTO POCO ANTES DE ALCANZARSE EL PUNTO DE INVERSION INFERIOR, POR TANTO, TODAVIA ANTES DE COMPLETARSE EL PROCESO DE EMBUTICION. LAS FUERZAS QUE ACTUAN POR LA EXPLOSION DE LA CARGA PROPULSORA SOBRE EL PUNZON (7) Y SOBRE LA CAMARA HERRAMIENTA (9) POR BREVE TIEMPO EN DIRECCION DEL MOVIMIENTO (24) DE LA CAMARA HERRAMIENTA, SE MANTIENEN ALEJADAS DE LA CONSTRUCCION DE LA PRENSA (2) POR UNA CARGA DE MASAS DE ESTAS PIEZAS ADECUADAMENTE DIMENSIONADA.THE INVENTION REFERS TO A PROCESS FOR THE DEEP HYDROMECHANICAL STAMPING OF PLATE (8) IN A MOLD PREFIXED BY A PUNCH (7) THROUGH A PRESS (1), WHICH CONTAINS THE PUNCH AND A TOOL CHAMBER (9) OPEN TO THE PUNCH THAT CAN BE LOADED WITH LIQUID, FOR WHICH ONE OF THE TWO PARTS CAN BE OPERATED WITH A RUNNING MOVEMENT. THE SHEET IS CLAMPED BY ITS OUTER EDGE BETWEEN A CONTACT SURFACE (5) ON THE FRONT FACE OF THE PUNCH AND AN OPPOSING CONTACT SURFACE (5) CONFORMING CORRESPONDINGLY ON THE FRONT FACE OF THE CHAMBER TOOLS WITH LIQUIDS AND WITH OUTSIDE. THE CHAMBER TOOL IS WIDELY FILLED WITH LIQUID THAT IS UNDER INCREASING PRESSURE, THEREFORE THE SHEET MOVES WITH SLIP OF ITS EDGE FROM THE PERIPHERAL SUPPORT (5) STRETCHED BY THE PRESSURE OF THE LIQUID IN THE FORM OF THE GRAB AWL. TO SHORTEN THE PRESSURE FORMATION UP TO THE NECESSARY FINAL PRESSURE AND DOWNLOAD THE PRESS OF VERY HIGH FORCES, A DOSED PROPELLING LOAD IS INTRODUCED IN THE CHAMBER TOOL, PREFERRED IN THE FORM OF A FUEL GAS (14X). 15), WHICH LIGHTS AT A CERTAIN MOMENT JUST BEFORE THE LOWER INVESTMENT POINT IS REACHED, THEREFORE, STILL BEFORE COMPLETING THE EMBUTTITION PROCESS. THE FORCES THAT ACT FOR THE EXPLOSION OF THE PROPELLING LOAD ON THE PUNCH (7) AND ON THE TOOL CHAMBER (9) FOR A SHORT TIME IN DIRECTION OF THE MOVEMENT (24) OF THE TOOL CHAMBER, KEEP AWAY FROM THE CONSTRUCTION OF THE PRESS ( 2) BY A CHARGE OF MASSES OF THESE PIECES ADEQUATELY SIZED.
