Abstract

Une presse hydraulique dont le coulisseau 4 est entraîné d'abord dans une course rapide d'approche par des unités cylindre-piston 8, 9, puis par un piston 5 qui assure la course de travail, à sa course limitée normalement par un contacteur de fin de course 11 actionné par le déplacement du coulisseau. Dans le cas où il se produit, par suite de la présence d'un corps étranger 24 dans la zone de l'outil, un ralentissement du mouvement du coulisseau, avant l'intervention du contacteur de fin de course 11, un autre élément de contacteur constitué par exemple d'une crémaillère 32 et d'un pignon 33, émet des signaux de ralentissement qui déclenchent un signal d'incident.
