Abstract

L'invention concerne une panne à brides à deux couches (1) et son procédé de préparation. Des brides de la panne sont chacune pliées pour former une bride à deux couches (1), et des plaques d'acier pliées de la bride à deux couches (1) sont partiellement soudées et fixées les unes aux autres. Dans la présente solution technique, les brides d'acier à section formée à froid sont pliées en deux, de telle sorte que l'effet d'épaississement des brides est obtenu. Par comparaison avec une panne avec un matériau uniforme, le moment d'inertie anti-flexion de la panne est efficacement augmenté dans la présente solution technique, sans augmenter la quantité d'acier utilisée dans la panne. De façon similaire, par comparaison avec une panne ayant le même moment d'inertie, la quantité d'acier utilisée dans la panne dans la présente solution technique est considérablement réduite. De plus, les plaques d'acier de la bride à deux couches sont partiellement soudées, de telle sorte que la ligne avec la bride à deux couches (1) est contrainte dans son ensemble pour garantir que la bride à deux couches (1) ne se divise pas, ce qui permet d'assurer la capacité de support de celle-ci. Dans un procédé d'usinage de la présente solution technique, les procédés simples de cintrage à froid, de soudage et de pliage sont principalement utilisés pour la préparation, de telle sorte qu'une augmentation des coûts de fabrication est limitée, ce qui permet d'améliorer significativement l'économie apportée par les performances du produit.
