Abstract

EL DISPOSITIVO ABARCA UNA UNIDAD (1) DE HERRAMIENTA CON UNA HERRAMIENTA (4) DE CONFORMADO A BASE DE UNA ESTAMPA (6) Y UNA CONTRAESTAMPA (5). SE HA PREVISTO ADEMAS UNA CARCASA (11), EN DONDE SE DISPONE DE UNA PUA (12) DE ESTANQUEIDAD Y UN TRANSFORMADOR (25) DE PRESION. UN CURSOR (34) DE CUÑA PUEDE APOYAR LA PUA (12) DE ESTANQUEIDAD MEDIANTE DESCENSO DE LA PARTE (3) SUPERIOR DE PRESIONADO, DE TAL MODO QUE LA PUA (12) DE ESTANQUEIDAD DISPONE DE UNA APLICACION ESTANCA CON EL COMPONENTE (8) DE FORMA TUBULAR EN LA HERRAMIENTA (4) DE CONFORMADO. SE ACTIVA ADEMAS EL TRANSFORMADOR (25) DE PRESION A TRAVES DEL DESCENSO DE LA PARTE (3) SUPERIOR DE PRESIONADO Y SE GENERA LA PRESION DE CONFORMADO HIDRAULICA NECESARIA EN EL COMPONENTE (8). LA HERRAMIENTA (4) DE CONFORMADO CERRADA ES APOYABLE MEDIANTE RESORTE (40) DE FORMA RELATIVA CON RESPECTO A LA PARTE (3) SUPERIOR DE PRESIONADO. EL CURSOR (34) DE CUÑA SE APOYA EN UN REAPOYO (32).
