Abstract
ESTEMPLE HIDRAULICO DE ACERO CON UN ESTEMPLE INFERIOR FORMADO POR UN TUBO (1) CILINDRICO EXTERIOR CON UN CILINDRO (14) BASE Y UN COLLAR ANULAR (16), CON UN ESTEMPLE SUPERIOR GUIADO EN EL ESTEMPLE INFERIOR, DESPLAZADO COAXIALMENTE A PARTIR DEL COLLAR ANULAR (16) Y UN ANILLO (12) GUIA FORMADO POR UN TUBO (2) CILINDRICO QUE PRESENTA UN EMBOLO (9) GUIADA Y ESTANQUEIZADA CONTRA LA PARED INTERIOR DEL TUBO (1) CILINDRICO EXTERIOR Y UN CAVBEZAL (4) DE ESTEMPLE, CON UN VALVULA (21) DE ASIENTO Y DE DESENTIBADO, UN LIMITADOR DE SALIDA INTERIOR Y UN MUELLE (6) RECUPERADOR. EL TUBO CILINDRICO EXTERIOR E INTERIOR SE SOPORTAN COMO EXTREMOS FRONTALES EN SALIENTES O RANURAS FRONTALES DE COLLARES ANULARES DE EMBOLOS, DE CILINDRO BASE Y SE ESTANQUEIZAN EN EMBOLOS CABEZALES DE ESTEMPLE Y CILINDRO BASE. ENTRE EL CABEZAL DEL ESTEMPLE Y EL EMBOLO ESTA PREVISTO UNA FUERZA DE TRACCION ENTRE LOS ELEMENTOS SOPORTANDO AMBOS COMPONENTES. UN ELEMENTO (9) COAXIAL DE TRACCION DISPUESTO EN LOS TUBOS CILINDRICOS SE FIJAEN EL CILINDRO BASE. EL ELEMENTO DE TRACCION COMO BARRA SOPORTE SE EXTIENDE A TRAVES DEL EMBOLO Y PRESENTA EN LOS EXTREMOS LIBRES UN ELEMENTO SOPORTE (8). SE DISPONE COAXIALMENTE AL ELEMENTO DE TRACCION UN RESORTE DE COMPRESION (6) COMO MUELLE RECUPERADOR. EL RESORTE DE COMPRESION SE APOYA EN EL ELEMENTO SOPORTE Y EN EL ELEMENTO SOPORTANDO LA FUERZA DE TRACCION O SE UNE UN COMPONENTE CON EL ELEMENTO O EL EMBOLO. LA UNION ENTRE LA VALVULA DE ASIENTO Y DE DESENTIBACION Y EL ESPACIO DE PRESION SE EFECTUA POR EL CABEZAL DE ESTEMPLE O POR EL CILINDRO BASE.
