Abstract

EN UN APARATO Y METODO PARA HIDROFORMACION, DE UN CONDUCTO DE PARED DOBLE QUE TIENE UN ESPACIO DE TAMAÑO CONTROLADO ENTRE LAS PAREDES, UN BASTIDOR (11) TIENE UNA TAPA SUPERIOR (11C) Y UN LECHO INFERIOR (11D) QUE DEFINEN UN ESPACIO DE HIDROFORMACION ENTRE LOS MISMOS, EL LECHO (11D) TENIENDO UN RESBALADOR QUE SE EXTIENDE DESDE EL ESPACIO A UNA POSICION DE CARGA-DESCARGAPREFORMA FUERA DEL ESPACIO. EN EL RESBALADOR UN ENSAMBLAJE DE MOLDEO TIENE UNA PLACA INFERIOR (17) Y UNA PLACA SUPERIOR (19) QUE DEFINEN AL MENOS DOS CAVIDADES DE HIDROFORMACION (14,16), UNA CAVIDAD SIENDO UNA PREFORMA ALARGADA Y UNA CAVIDAD SEMI-TERMINADA (14), Y LA OTRA CAVIDAD SIENDO UNA CAVIDAD DE TERMINACION ALARGADA (16). UN ELEMENTO DE DESPLAZAMIENTO DE MOLDE (15) ESTA COLOCADO PARA DESPLAZAR EL ENSAMBLAJE DE MOLDE EN EL RESBALADOR DESDE LA POSICION EN EL ESPACIO ENTRE LA TAPA (11C) Y EL LECHO (11D), A Y DESDE LA POSICION DELANTERA Y DE CARGA-DESCARGAPREFORMA. UN CIERRE DE MOLDE Y CILINDROS HIDRAULICOS DE PREFORMACION (27) ESTAN CONECTADOS DE FORMA OPERABLE A LA PLACA DE MOLDE SUPERIOR (19) PARA CERRAR LA PLACA SUPERIOR (19) EN LA PLACA INFERIOR (17) Y CREAR PREFORMACION MECANICA EN MATERIAL TUBULAR DE PARED DOBLE EN LA PREFORMA Y CAVIDAD DE FORMA SEMITERMINADA (14). LA TAPA SUPERIOR (11C) TIENE UNA BOLSA RETENIDA PERIFERICAMENTE (33) SOBRE EL ENSAMBLAJE DE MOLDE PARA APLICAR UNA FUERZA DE AMORTIGUAMIENTO DE CIERRE EN EL ENSAMBLAJE DE MOLDE MEDIANTE LA BOLSA (33). UN PRIMER PAR DE DOBLE ACTUACION, CERRADO DE TUBOS, ELEMENTOS DE HIDROFORMACION ESTAN EN LOS EXTREMOS DE LA PREFORMA, CAVIDAD SEMITERMINADA (14), Y UN SEGUNDO PAR DE ELEMENTOS DE HIDROFORMACION DE CIERRE DE TUBO (40) SE ENCUENTRAN EN LOS EXTREMOS DE LA CAVIDAD TERMINADA.
