Abstract

L'invention concerne les systèmes de commande des presses. Le système de commande faisant l'objet de l'invention est du type comportant un système de couplage mécanique à réaction comprenant deux éléments rotatifs 4 et 5 montés sur un arbre de commande 3 et pourvus de saillies 8 et 9 sur leurs faces respectives mutuellement en regard, l'un desdits éléments rotatifs étant relié à la traverse 2 et sa rotation étant proportionnelle au déplacement de ladite traverse, tandis que l'autre élément rotatif est relié à la commande du distributeur 1, et est caractérisé notamment en ce que l'un desdits éléments rotatifs est monté sur ledit arbre de commande de manière qu'il puisse se séplacer en translation par rapport à ce dernier d'une valeur directement proportionnelle à son angle de rotation, de manière à assurer une mise en contact progressive desdites saillies entre elles. L'invention s'applique notamment aux presses hydrauliques de martelage.
