Abstract

EN UN APARATO ESTIRADOR (2) GRADUABLE DE UNA PRENSA, LA ZONA DE PRENSADO ESTA SUBDIVIDIDA EN SEGMENTOS (4), EN CUYAS ZONAS ANGULOSAS SE ENGANCHAN LOS CILINDROS DE PRESION. EL CILINDRO DE PRESION ESTA FIJO EN LAS PRENSAS. SUS BARRAS DE EMBOLOS ACTUAN SOBRE BARRAS DE PRESION (10), SOBRE UNA CONSOLA ELEVABLE Y DESCENDIBLE. SE HA PREVISTO QUE HAYA, AL MENOS, UN CILINDRO DE BLOQUEO (14) QUE POR MEDIO DE UN PUENTE DE ELEVACION, SE ENGRANA EN LA CONSOLA E IMPIDE, RESPECTO DE SU CAPACIDAD DE PRESION, UN MOVIMIENTO HACIA ADELANTE DE LA CONSOLA Y TAMBIEN DE LA ZONA DE PRESION (3). EL TIEMPO QUE TARDA DESDE LA FASE DE REPOSO HASTA LA DE MAYOR RECORRIDO, SE PUEDE DETERMINAR CONTROLANDO LA PRESION POR MEDIO DE UNA VALVULA, EN LOS CILINDROS DE BLOQUEO (14).
