Abstract

L'invention concerne les perfectionnements aux cisailles à tôles et plaques. L'invention décrit une cisaille à action de roulement qui comprend un bâti supportant une lame fixe et une lame mobile reliée à des moyens de support et d'actionnement comprenant deux mécanismes à genouillère, des moyens de liaison des mécanismes à genouillère pour qu'ils pivotent simultanément, des moyens d'actionnement hydrauliques reliés aux mécanismes à genouillère pour entraîner ceux-ci autour de leur axe et des moyens de guidage de la lame mobile, l'ensemble étant tel que cette dernière exécute un mouvement de roulement par rapport à la lame fixe. L'invention s'applique, en particulier aux machines-outils en particulier les cisailles pour tôles fortes et plaques.
