Abstract

Dispositif utilisant un générateur de signaux agissant pratiquement sans déplacement, en fonction de la pression. Le bâti 1 de la presse porte l'outil supérieur 2, l'outil inférieur 3 étant porte par le coulisseau 4 qui est actionné par le groupe hydraulique formé par le piston 5 et le cylindre 6 de travail, ainsi que par les vérins rapides comportant les cylindres 7, les pistons et les tiges 9. On a représenté en 10 le matériau à découper, en 24 l'objet perturbateur et en 25 les cellules de mesure de pression. L'interrupteur de fin de course 11 est commandé par la surface de came 12. Le circuit hydraulique comprend en outre une pompe 14, un réservoir 15, deux électrovalves 17 et 22, une soupape antiretour 18, un manomètre 23.
