Title (EN) A COLD ROLLING SYSTEM
(FR) SYSTÈME DE LAMINAGE À FROID
Abstract:
(EN) The present invention relates to a cold rolling system. The die and roller assembly (5) of the system comprises of at least two profiled rolls (die) mounted in a horizontal plane. The profiled rolls are mounted on a vertical shaft (51 ) wherein the said assembly is slidably fitted on the guide rods (6) so that it could reciprocate on the said guide rods (6). The said assembly is coupled to the first end of connecting rod (4) that is operated by the crank gear (20) of the driving system (306). The synergistic combination of disposition of the profiled rolls in horizontal plane, use of the gear for speed reduction as well as providing cam effect and use of drive shaft as guide bar results in obviating problems associated with the work head and unbalanced forces, failure of the mandrel, reduced stroke frequency of the work head and undesirable marks on the finished tube surface.
(FR) La présente invention se rapporte à un système de laminage à froid. L'ensemble matrice et cylindre (5) du système se compose d'au moins deux cylindres profilés (matrice) montés dans un plan horizontal. Les cylindres profilés sont montés sur un arbre vertical (51), ledit ensemble étant ajusté coulissant sur les tiges de guidage (6) de sorte qu'il puisse être animé d'un mouvement de va-et-vient sur lesdites tiges de guidage (6). Ledit ensemble est accouplé à la première extrémité d'une tige de liaison (4) qui est actionnée par l'engrenage à manivelle (20) du système d'entraînement (306). La combinaison synergique de la disposition des cylindres profilés dans le plan horizontal, de l'utilisation de l'engrenage pour la réduction de vitesse ainsi que de la mise en œuvre d'un effet de came et de l'utilisation d'arbres d'entraînement en tant que barre de guidage permet d'éviter les problèmes associés à la tête de travail et aux forces déséquilibrées, la panne du mandrin, la fréquence de course réduite de la tête de travail et les marques indésirables sur la surface de tube finie.
