Abstract

Le dispositif permet le blocage et le déblocage rapides, sans boulons, d'une filière sur la tête rotative d'une presse. Il comporte un anneau élastique conique d qui prend appui sur la surface correspondante d'un anneau d'acier c sous l'action de ressorts montés sur des tiges f et qui vient ainsi bloquer la filière b. Le déblocage est obtenu par l'action d'un piston l annulaire sur les tiges f repoussant l'anneau d qui s'ouvre élastiquement. L'invention peut être utilisée sur des presses à fourrage.The device allows fast locking and unlocking, without bolts, of a die on the rotary head of a press. It comprises a conical elastic ring d which bears on the corresponding surface of a steel ring c under the action of springs mounted on rods f and which thus blocks the die b. Unlocking is obtained by the action of an annular piston l on the rods f pushing back the ring d which opens elastically. The invention can be used on forage balers.
