Abstract

La présente invention a pour objet un dispositif de commande de pilons. Elle est caractérisée en ce que ce dispositif comprend un organe de manoeuvre, un génerateur de signaux, une unité pneumatique de commande principale servant à actionner un cylindre de travail à double effet qui entraîne l'un ou les deux marteaux du pilon, le générateur de signaux comportant un piston muni d'une arête de commande qui coulisse dans un cylindre pourvu de trous de commande et une unité logique pneumatique de commande à éléments ET et NON-ET assurant le contrôle du déroulement de la séquence des différents mouvements dans le pilon. Elle se rapporte à des pilons d'estampage à contre-coups.The present invention relates to a device for controlling pestles. It is characterized in that this device comprises an operating member, a signal generator, a main pneumatic control unit serving to actuate a double-acting working cylinder which drives one or both hammers of the pestle, the generator of signals comprising a piston provided with a control edge which slides in a cylinder provided with control holes and a pneumatic control unit with AND and NAND elements ensuring the control of the sequence of the various movements in the ram. It relates to back-stamping pestles.
