Abstract

UN DISPOSITIVO PARA LA CONFORMACION O PERFILADO DE CUERPOS (19) HUECOS DE METAL TRABAJO EN FRIO CON UN HUECO (17) DE PERFILADO DE UN TROQUEL (12) ESTA EQUIPADO CON UN SISTEMA PARA EL SUMINISTRO DE FLUIDO BAJO PRESION EN EL INTERIOR DEL CUERPO (19) HUECO. EL SISTEMA DE SUMINISTRO SE COMPONE DE UN ACOPLAMIENTO (23) DE MANGUITO DE SUMINISTRO QUE TRANSPORTA EL FLUIDO BAJO PRESION Y QUE PUEDE SER MONTADO Y DESMONTADO EN RELACION AL CUERPO (19) HUECO CONTENIDO EN EL TROQUEL (12) Y BLOQUEADO EN LA POSICION DE SUMINISTRO. EL ACOPLAMIENTO (23) DE CASQUILLO DE SUMINISTRO PUEDE SER EMPUJADO HACIA EL FRENTE DE LA REGION (22) DE AGARRE CILINDRICA DEL CUERPO (19) HUECO LOCALIZADO FUERA DEL HUECO (17) DE PERFILADO DEL TROQUEL (12). EN LA POSICION DE SUMINISTRO, EL ACOPLAMIENTO (23) DE MANGUITO ACEPTA LA ZONA (22) DE AGARRE EN LA POSICION DE SUMINISTRO DE FORMA QUE ES MOVIBLE AXIALMENTE Y LO SUJETA POR MEDIO DE UN CIERRE ESTANCO (36) DE CASQUILLO QUE ES IMPERMEABLE DE FORMA AUTOMATICA POR MEDIO DE LA PRESION DEL FLUIDO.
