Title (EN) CUTTING OR PRESSING DEVICE AND METHOD
(FR) DISPOSITIF ET PROCEDE DE DECOUPAGE OU DE TRANCHAGE
Abstract:
(EN) A cutting or pressing device operable by an electromagnetic linear actuator (5, 6), preferably for use in dehorning cattle, cutting cables, cutting steel mesh, and other cutting or pressing operations. The device is provided with handles (8) on the frame (1), with a stationary blade (2) and a moveable blade (3). The moveable blade (3) is actuated by actuator (5, 6), which is driven by motor (18) connected to power source (13). Preferably, the actuator (5, 6) is provided with a spring tension accumulator assembly (20) which allows the cutting or pressing operation to be completed quickly after an initial larger force, or, a hydraulic multiplier assembly (40) which allows a larger force to be applied in compromise for a reduction in distance moved.
(FR) L'invention se rapporte à un outil à couper ou a trancher, qui peut être actionné par un actionneur linéaire électromagnétique (5, 6) et qui sert de préférence à décorner du bétail, à couper des câbles, à couper des treillis métalliques et à effectuer d'autre opérations de découpage ou de tranchage. L'outil est pourvu de poignées (8) disposées sur le cadre (1) et comporte une lame fixe (2) et une lame mobile (3). La lame mobile (3) est actionnée par un actionneur (5, 6), lequel est entraîné par un moteur (18) connecté à une source de courant (13). L'actionneur est de préférence pourvu d'un accumulateur de tension à ressort (20), qui permet de terminer rapidement l'opération de découpage ou de tranchage après l'application d'une force initiale plus grande, ou d'un multiplicateur hydraulique (40) qui permet l'application d'une force plus grande pour consentir une réduction de la distance de déplacement.
