Abstract
Procedimiento para fabricar un árbol que presenta al menos un abombamiento como un cojinete de elevación, una leva (N1, N2) o un escalón de cojinete, a partir de una pieza tubular (R), según el cual la pieza tubular (R) se apoya radialmente en una sección (Re) colindante con la zona de abombamiento a realizar, la pieza tubular (R) se somete a una presión interna (Pi) que se mantiene durante todo el procedimiento de conformación, mediante la aplicación, en acción conjunta con la presión interna (Pi), de una fuerza de presión (Da) que actúa en el sentido axial sobre la pieza tubular, una sección tubular (Rs) colindante con la sección (Re) apoyada radialmente se recalca de tal forma que el diámetro exterior de esta sección tubular (Rs) recalcada sea superior al diámetro exterior de la pieza tubular (R) no recalcada, a continuación, en la sección tubular (Rs) recalcada se aplica una herramienta de moldeo (16a 20b) que presenta un ahondamiento (16c, 16d) que forma un molde hueco correspondientea la forma final del abombamiento a originar, mediante la aplicación de fuerzas de presión de acción radial mediante la herramienta de moldeo (16a 20b), a partir de la sección tubular (Rs) recalcada se moldea el abombamiento.
