Abstract

L'invention concerne les constructions mécaniques. Les cylindres de dressage faisant l'objet de l'invention sont caractérisés notamment en ce que le cylindre d'appui 1 est réalisé sous la forme d'un corps de révolution à deux concavités, les portées 2 et 2a adjacentes aux faces en bout respectives de ce cylindre présentant chacune une concavité hyperboloïde identique à celle de l'autre et dont la courbure est telle que ledit cylindre d'appui s'applique sur une partie médiane relativement mince de la pièce 4, tandis que la portée médiane 3 du cylindre d'appui 1 une concavité hyperboloïde dont la courbure permet la flexion nécessaire d'une extrémité relativement epaisse de la pièce 4 pour assurer son dressage. Les cylindres en question peuvent être utilisés pour le dressage de pièces pleines ou creuses dont les parties extrêmes ont un diametre plus grand que le diamètre de leur partie médiane (tubes à bouts renflés, arbres à bouts renforcés, etc.).
