Abstract

Mejoras en sistemas de amortiguación de choques para prensas, especialmente para una prensa de cizalla que tiene medios de bastidor que incluyen medios de leche y medios de cursor soportantes susceptibles de moverse alternativamente, y en que el material es cortado entre medios de cizallamiento susceptibles de cooperar, soportados por dichos medios de leche y dichos medios de cursor, incluyendo dichos medios de cizallamiento soportados por dichos medios de lecho unos medios de miembro de cizallamiento y unos medios de soporte de miembro de cizallamiento, incluyendo dicho sistema unos medios de cámara de volumen variable receptores de fluido hidráulico entre dichos medios de leche y dichos medios de cursor y conectados con un manantial de fluido hidráulico bajo presión, incluyendo dichos medios de cámaras de volumen variable unos medios de cilindro y unos medios de pistón desplazables en dichos medios de cilindro, siendo dichos medios de cámara susceptibles de funcionar bajo compresión comorespuesta a la penetración a través del material que está siendo cizallado por dichos medios de cizallamiento soportados por dichos medios de cursor para restringir el movimiento acelerado de dichos medios de cursor, y medios de control de circulación de fluido susceptibles de funcionar para controlar la circulación de fluido desde dichos medios de cámara, caracterizados porque uno de entre dichos medios de miembro de cizallamiento y de dichos medios de soporte de miembro de cizallamiento incluye medios que proporcionan dichos medios de cilindro, estando montados dichos medios de control de circulación sobre dichos medios de soporte de miembro de cizallamiento, y que dichos medios de soporte de miembro de cizallamiento incluyen en ellos medios de pasaje de circulación de fluido susceptibles de ser conectados con dicho manantial de fluido hidráulico y que conectan a dichos medios de cilindro y a dichos medios de control de circulación en comunicación de circulación de fluido.
