Abstract

Machine à sertir un tube dans une feuille métallique à gorge préformée de réception du tube. Cette machine comporte un bâti supportant plusieurs paires échelonnées de galets identiques à entraxes décroissants formant un chemin rectiligne de sertissage progressif pour l'ensemble tube-feuille, ces galets ayant un profil qui correspond à celui de sertissage de la gorge de la feuille sur le tube après leur passage entre la dernière paire de galets. Application à la réalisation d'échangeurs de chaleur.Machine for crimping a tube in a metal foil with a preformed groove for receiving the tube. This machine comprises a frame supporting several staggered pairs of identical rollers with decreasing centers forming a rectilinear progressive crimping path for the tube-sheet assembly, these rollers having a profile which corresponds to that of crimping the throat of the sheet on the tube. after their passage between the last pair of rollers. Application to the production of heat exchangers.
