Title (EN) TRANSVERSE STRUT AND METHOD OF FORMING A TRANSVERSE STRUT
(FR) TRAVERSE ET PROCÉDÉ DE FORMATION D'UNE TRAVERSE
Abstract:
(EN) A roll forming assembly for forming a transverse strut from a tube is provided. The roll forming assembly includes a heater, such as an induction heater, for heating a tube to a predetermined annealing temperature. Next, the tube is fed to a roll former, which includes a plurality of forming wheels to shape the tube into a transverse strut. Servo motors are operably coupled to the forming wheels for adjusting the positions of the forming wheels in a radial direction during the roll forming process to give the transverse strut a variable profile along its length. After the roll forming process is completed, the transverse strut is quenched so that its base material is given a predetermined microstructure.
(FR) L'invention concerne un ensemble de profilage pour la formation d'une traverse à partir d'un tube. L'ensemble de profilage comprend un réchauffeur, tel qu'un réchauffeur par induction, pour chauffer un tube à une température de recuit prédéterminée. Ensuite, le tube est envoyé à un formeur à galets, qui comprend une pluralité de galets de formage pour façonner le tube en une traverse. Des servomoteurs sont couplés de façon fonctionnelle aux galets de formage pour ajuster les positions des galets de formage dans une direction radiale pendant le processus de profilage, pour donner à la traverse un profil variable le long de sa longueur. Après l'achèvement du processus de profilage, la traverse est trempée de telle sorte qu'une microstructure prédéterminée est conférée à son matériau de base.
