Abstract
Perfeccionamientos en los dispositivos articulados de cierre y bloqueo para prensas de accionamiento por fluido, prensas de tipo horizontal, vertical o inclinada, empleadas aisladamente o acopladas a otras unidades de trabajo, y que comprenden: - un cabezal o plano de reacción (29), longitudinalmente yuxtapuesto a una placa fija (11); una placa móvil (30) montada entre dicho cabezal o plano de reacción y la placa fija mencionada, deslizable sobre columnas paralelas entre sí (12) solidarias al cabezal o plano de reacción (29) y a la placa fija (11); dicha placa móvil (30) de deslizamiento activable en ambos sentidos por la acción neumática, hidroneumática, oleodinámica o hidráulica de cilindros con pistones de doble efecto asociados a conjuntos de palancas articuladas, caracterizado por el hecho de que el movimiento de aproximación y bloqueo y de desbloqueo y alejamiento de la placa móvil (30) respecto a la placa fija (11), respectivamente, es generado secuencialmente por dos cilindros diferentes o conjuntos de cilindros (33, 36) con pistones de doble efecto (31, 35) uno o más cilindros (33) que genera el movimiento de acercamiento, presentan un extremo unido a la placa móvil (30) y el extremo opuesto, atravesado axialmente por el vástago (32) del correspondiente pistón (31), unido con acoplamiento deslizable (51) a una cruceta (38) - el extremo libre del vástago (32) está unido en un punto (50) al cabezal de reacción (29), a la cruceta (38), estando articulados conjuntos de palancas (39, 42, 45) que realizan movimientos articulados mediante pernos (43) al cabezal de reacción (29), siendo el cilindro de bloqueo (36) con pistón de doble efecto (35) solidario con la cruceta (38); en tanto que el vástago (37) del pistón correspondiente (35) presenta el extremo libre solidario con la placa móvil (30) con el fin de realizar un movimiento alterno de acercamiento y de alejamiento respectivamente, de la placa móvil (30), respecto a la placa fija (11) originado directamente por el movimiento del cilindro o cilindros (33) respecto al pistón o pistones fijos (31) y de realizar en secuencia al movimiento de acercamiento, el movimiento de bloqueo, mediante la activación del cilindro de doble efecto (36) con el pistón (35) actuando dicho cilindro (36) sobre la cruceta (38) provoca la alineación de los ejes (43, 44, 46) de los puntos de articulación del mecanismo articulado, y viceversa, en la fase de desbloqueo y consiguiente fase de alejamiento de la placa móvil (30) respecto a la placa (11) fija; caracterizado además por su estructura de acuerdo con la cual el cilindro o los cilindros de aproximación (33), con los pistones (31) y los vástagos (32) están situados en el interior del perímetro máximo del armazón de la máquina junto con el mecanismo o mecanismos articulados que comprenden brazos (39, 42, 45) articulados mutuamente sí como articulados en los puntos (43) al cabezal de reacción (29); en los puntos (46) a la placa móvil (30) y en los puntos (40) a la cruceta (38).
