Abstract

UN METODO Y UN APARATO CAPAZ DE FORMAR UN CONDUCTO DE DOS TUBOS QUE TENGA UNA DIMENSION DEL TUBO EXTERIOR PREDETERMINADA, UNA DIMENSION DEL TUBO INTERIOR PREDETERMINADA Y UN ESPACIO PREDETERMINADO ENTRE LOS DOS TUBOS. EN PRIMER LUGAR SE DOBLA UNA PIEZA DE TRABAJO DE DOS TUBOS (W) POR UNA O MAS ZONAS HASTA QUE TOME UNA FORMA NO LINEAL DESEADA, SE EXPANDEN POR HIDROCONFORMACION EL TUBO INTERIOR (50) Y EL TUBO EXTERIOR (52) SIMULTANEAMENTE HASTA OBTENER LA DIMENSION SELECCIONADA PARA EL TUBO INTERIOR Y A CONTINUACION SE EXPANDE POR HIDROCONFORMACION EL TUBO EXTERIOR HASTA ALCANZAR LA DIMENSION DESEADA PARA EL TUBO EXTERIOR Y EL ESPACIO DESEADO ENTRE MEDIAS, MIENTRAS QUE EL TUBO INTERIOR SE MANTIENE CONSTANTE.
