Title (EN) ANTI-FALL DEVICE IN PARTICULAR FOR HYDRAULIC PRESSES
(FR) DISPOSITIF ANTICHUTE EN PARTICULIER POUR PRESSES HYDRAULIQUES
Abstract: front page image
(EN)The invention concerns an anti-fall device (10) for machines (11 ), such as blanking, braking presses and the like, that have a movable platen or ram (14) moving, by means of a main hydraulic cylinder connected to them, along guide bars (15) above a fixed work table (12). The device comprises a redundant auxiliary hydraulic cylinder (20, 21 ) connected to the movable platen or ram (14) and fed by its own hydraulic circuit (22) and connected to said main control cylinder of the movable platen or ram (14) so as to download and recollect the hydraulic fluid from and to its jacket, only in reply to the movements of the movable platen or ram dynamically from the main cylinder.
(FR)La présente invention se rapporte à un dispositif antichute (10) pour machines (11), telles que des presses à découper, de freinage et similaires, qui comportent une platine ou un piston mobile (14) se déplaçant, au moyen d’un vérin hydraulique principal relié à elles, le long de barres de guidage (15) situées au-dessus d’une table de travail fixe (12). Le dispositif comprend un vérin hydraulique auxiliaire redondant (20, 21) relié à la platine ou au piston mobile (14) et alimenté par son propre circuit hydraulique (22) et relié audit vérin de commande principal de la platine ou du piston mobile (14) de manière à charger le fluide hydraulique depuis sa chemise et à le retourner dans celle-ci, uniquement en réponse aux déplacements de la platine ou du piston mobile de façon dynamique depuis le vérin principal.
