Abstract

La présente invention a pour objet un dispositif de sécurité pour presse mécanique à excentrique. Ce dispositif comporte un arbre vertical 1 présentant un décrochement lequel est relié à sa partie inférieure au coulisseau 12 de la presse de manière à suivre les déplacements verticaux alternatifs du coulisseau et deux chariots indépendants 5 mobiles indépendamment transversalement à l'arbre sous l'action des deux vérins pneumatiques indépendants 3-4 commandés ar les deux poussoirs de sécurité de la commande de la presse, les deux chariots venant s'engager, dans le fonctionnement au coup par coup, et lors de l'interruption de l'action sur le poussoir de sécurité correspondant, immédiatement en dessous du décrochement de l'arbre 1 dans sa position correspondant au moins mort supérieur. Le dispositif conforme à l'invention évite les coups redoublés ou intempestifs dans le fonctionnement au coup par coup.The present invention relates to a safety device for an eccentric mechanical press. This device comprises a vertical shaft 1 having a recess which is connected at its lower part to the slide 12 of the press so as to follow the alternating vertical movements of the slide and two independent carriages 5 movable independently transversely to the shaft under the action of two independent pneumatic cylinders 3-4 controlled by the two safety push-buttons of the press control, the two carriages coming into engagement, in piecemeal operation, and when the action on the push-button is interrupted corresponding safety device, immediately below the step of the shaft 1 in its position corresponding to the least upper dead. The device according to the invention avoids repeated or unwanted blows in the piecemeal operation.
