Abstract

UNAS CIZALLAS MANUALES ACCIONADAS POR UN MOTOR HIDRAULICO QUE SE CARACTERIZA PORQUE TIENE UN CUERPO (10) QUE INCLUYE UNA PORCION DE MANGO DE AGARRE TIPO PISTOLA (11), UNA RANURA QUE RECIBE LAS HOJAS (12) Y UNA CAVIDAD CILINDRICA (30) CON UNA CUBIERTA EXTRAIBLE COLOCADA SOBRE LA RANURA QUE RECIBE LAS HOJAS (12). SE PUEDEN COLOCAR EN LA RANURA QUE RECIBE LAS HOJAS (12) UNO DE UNA VARIEDAD DE PARES DE HOJAS DE CIZALLAMIENTO INTERCAMBIABLES DE DISTINTOS TAMAÑOS Y FORMAS (13, 14). LAS HOJAS SE ENCUENTRAN CONECTADAS DE MANERA PIVOTANTE Y CADA UNA TIENE UNA SECCION CONTANTE ANTERIOR QUE SE PROYECTA HACIA ADELANTE DEL ALOJAMIENTO Y UNA EXTENSION POSTERIOR, PUDIENDO ENTRAR LAS EXTENSIONES DE MANERA EXTRAIBLE EN LA RANURA QUE RECIBE LAS HOJAS PARA SUJETAR A UNA HOJA DE MANERA FIJA MIENTRAS QUE PERMITE EL MOVIMIENTO RELATIVO DE LA OTRA. UN EXTREMO DE UN VASTAGO DEL PISTON (32) QUEDA FIJADO A UN PISTON (31) QUE HAY EN LA CAVIDAD CILINDRICA (30) PARA QUE SE PUEDA MOVER DE MANERA RECIPROCA EN SU INTERIOR. EL OTRO EXTREMO DEL VASTAGO DEL PISTON SE ENCUENTRA ENGANCHADO DE MANERA DESENGANCHABLE AL EXTREMO POSTERIOR DE LA EXTENSION (22) DE LA HOJA DE CIZALLAMIENTO RELATIVAMENTE MOVIL. DENTRO DEL CUERPO (10) HAY UNOS ORIFICIOS PARA LA CIRCULACION DEL FLUIDO (41, 42, 43, 44), QUE ESTAN ADAPTADOS PARA PODER QUEDAR CONECTADOS A UNA FUENTE DE FLUIDO A PRESION Y EN COMUNICACION CON LA CAVIDAD CILINDRICA (30) EN LOS LADOS OPUESTOS DEL PISTON (31) PARA LA INTRODUCCION DEL FLUIDO A LA MISMA Y LA SALIDA DEL FLUIDO DE LA MISMA. HAY UNAS VALVULAS PARA CONTROLAR LA CIRCULACION DEL FLUIDO A TRAVES DE LAS CIZALLAS. HAY UNOS ELEMENTOS DISPARADORES DE POTENCIA (57), QUE SE PUEDEN ACCIONAR DESDE EL MANGO DE AGARRE TIPO PISTOLA (11), PARA ACTIVAR LAS VALVULAS DE CONTROL (51) Y UNOS ELEMENTOS DISPARADORES DE SEGURIDAD (63) QUE SE PUEDEN ACCIONAR DESDE EL MANGO DE AGARRE TIPO PISTOLA (11) PARA PREVENIR EL FUNCIONAMIENTO ACCIDENTAL DEL DISPARADOR DE POTENCIA (57).
