Abstract
SISTEMA HIDRAULICO DE CONTROL DE SOBRECARGA PARA UNA PRENSA MECANICA. CONSTA DE MEDIOS GENERADORES DE UNA PRIMERA SEÑAL ELECTRICA QUE TIENE UN VALOR PROPORCIONAL A LA FUERZA EJERCIDA SOBRE EL TROQUEL POR EL CURSOR EN TODA LA CARRERA DE TRABAJO; DE MEDIOS PARA GENERAR UNA SEGUNDA SEÑAL ELECTRICA QUE TIENE UN VALOR PROPORCIONAL A LA POSICION DEL CURSOR EN TODA LA CARRERA DE TRABAJO; DE MEDIOS PARA ALMACENAR LOS VALORES MAXIMOS DE CAPACIDAD DE TONELAJE DE LA PRENSA, EN UNA MULTIPLICIDAD DE POSICIONES DEL CURSOR, EN TODA LA CARRERA DE TRABAJO; DE MEDIOS DE CONTROL QUE RESPONDEN A LA SEGUNDA SEÑAL, PARA RECUPERAR EL VALOR ALMACENADO QUE REPRESENTA LA CAPACIDAD MAXIMA DE TONELAJE DE LA PRENSA EN LA POSICION DEL CURSOR REFERIDA POR DICHA SEGUNDA SEÑAL; DE MEDIOS PARA COMPARAR EL VALOR RECUPERADO CON EL VALOR DE LA PRIMERA SEÑAL; Y DE MEDIOS QUE RESPONDEN A LA DETERMINACION DE UNA CONDICION DE SOBRECARGA.
