Abstract

Compteur de pièces pour une presse mécanique 10 ayant une table de presse 11 et un coulisseau alternatif 12 actionné par un volant 14 par l'intermédiaire d'un embrayage et d'un arbre manivelle 15. Il comporte : a. des moyens pour calculer l'énergie du volant sur la base de sa vitesse de rotation, b. des moyens pour calculer toute perte d'énergie du volant, c. des moyens pour déterminer la perte d'énergie maximale pendant chaque révolution de l'arbre manivelle, d. des moyens pour comparer cette perte d'énergie maximale à une valeur prédéterminée et e. un dispositif de comptage qui est actionné chaque fois que cette perte d'énergie maximale dépasse cette valeur prédéterminée.
