Abstract
POR UNA UNIDAD HIDRAULICA DE LA HERRAMIENTA DE ESTIRAMIENTO ES CONVERTIBLE EL MOVIMIENTO DEL SOPORTE DE CHAPA (15) EN UN MOVIMIENTO SIMULTANEO AUNQUE CONTRAPUESTO DEL PUNZON DE ESTIRAMIENTO (17). LA UNIDAD HIDRAULICA MUESTRA UN EMBOLO DE TRABAJO CENTRAL (12), UN EMBOLO ANULAR QUE LO ENCIERRA (13) ASI COMO UN CILINDRO ENCERRADO EN EL EMBOLO ANULAR (10D). EL EMBOLO DE TRABAJO (12), UN EMBOLO ANULAR QUE LO ENCIERRA (13) ASI COMO UN CILINDRO ENCERRADO EN EL EMBOLO ANULAR (10D). EL EMBOLO DE TRABAJO (12) Y EL EMBOLO ANULAR (17) SE IMPULSAN FUERA DE ESPACIOS CILINDRICOS (51, 52, 48) HIDRAULICOS SEPARADOS UNOS DE OTROS QUE COMUNICAN UNO CON OTRO AL MENSO POR DOS CAMINOS DE CORRIENTE ALTERNATIVOS (CONDUCCIONES 20, 2A, 20B). LOS RECORRIDOS DE CORRIENTE PRODUCEN SOBRE LA BASE DE DIFERENTE EXPOSICION HIDRAULICA EN LOS ESPACIOS DE CILINDRO (51, 52, 48) QUE COMUNICAN UNOS CON OTROS UN PROCESO DE PRESION EN OTRO NIVEL DE PRESION. UN SENSOR DE PRESION (21) QUE ABARCA LA PRESION DEL MEDIO DE PRESION ENLOS ESPACIOS DE CILINDRO (51, 52, 48) CONECTA LOS RECORRIDOS DE CORRIENTE ALTERNATIVOS AL SOBREPASAR LAS PRESIONES LIMITE. ASI SE CONSIGUE QUE CON RESPECTO AL SOBREPASAR LAS PRESIONES LIMITE. ASI SE CONSIGUE QUE CON RESPECTO AL PERFIL DE DEFORMACION Y/O MATERIAL Y/O PROFUNDIDAD DE ESTIRAMIENTO PUEDAN FABRICARSE INCLUSO PARTES DE ESTIRAMIENTO DE EXTREMA DIFICULTAD SIN QUE DEBA RENUNCIARSE AL MONTAJE DE LA HERRAMIENTA DE ESTIRAMIENTO CON AHORRO DE COSTE Y ESPACIO.
