The present invention relates to a method and apparatus for forming an elongated tubular metal member from a tubular metal blank. The method comprises: i) placing a tubular metal blank having a generally oval cross section into a die cavity and orienting the tubular metal blank such that a relatively larger cross-sectional dimension of the generally oval cross section extends generally in a direction of the relatively larger cross-sectional dimension of the die cavity and such that a relatively small cross-sectional dimension of the generally oval cross section extends generally in a direction of the relatively small cross-sectional dimension of the die cavity; ii) engaging and sealing opposite ends of the tubular metal blank; and iii) injecting fluid under pressure into the tubular metal blank so as to expand the tubular metal blank into conformity with the surfaces defining the die cavity and thereby transform the tubular metal blank into the elongated tubular metal member.

La présente invention concerne un procédé et un appareil qui s'utilisent pour former un élément métallique tubulaire allongé à partir d'une ébauche métallique tubulaire. Le procédé consiste à: i) placer dans une cavité de la matrice une ébauche métallique tubulaire présentant une coupe transversale généralement ovale puis orienter ladite ébauche de sorte qu'une dimension de la coupe transversale relativement supérieure de la coupe transversale généralement ovale s'étende généralement dans une direction de la dimension de la coupe transversale relativement supérieure de la cavité de la matrice, et qu'une dimension de la coupe transversale relativement inférieure de la coupe transversale généralement ovale s'étende généralement dans une direction de la dimension de la coupe transversale relativement inférieure de la cavité de la matrice; ii) abouter et fermer hermétiquement des extrémités opposées de l'ébauche métallique tubulaire; et iii) injecter un fluide sous pression à l'intérieur de l'ébauche métallique tubulaire de manière à l'expanser et l'adapter aux surfaces délimitant la cavité de la matrice. On confère ainsi à l'ébauche métallique tubulaire sa forme allongée.
