Abstract

LA INVENCION SE REFIERE A UNA PINZA DE DEMOLICION CON MORDAZAS DE LA PINZA, CUYAS SECCIONES EXTREMAS SITUADAS EN EL EXTERIOR PRESENTAN EN CADA UNA, POR LO MENOS, UN SALIENTE QUE APUNTA A LA MORDAZA DE LA PINZA SITUADA ENFRENTE Y QUE EN COMBINACION CON ESTO ESTAN EQUIPADAS CADA UNA CON UNA ZONA CON CUCHILLA Y UNA ZONA DE CORTE A CONTINUACION. ESTA ZONA DE CORTE ESTA FORMADA POR UNA CUCHILLA DE CIZALLA QUE SE APOYA EN UNA SUPERFICIE DE ARRASTRE DE LA MORDAZA DE LA PINZA QUE ACTUA EN DIRECCION DEL MOVIMIENTO DE CIERRE DE LA PINZA Y ESTA SUJETA DESMONTABLE POR MEDIO DE ELEMENTOS DE SUJECION A LA MORDAZA, TRANSVERSAL AL MOVIMIENTO DE CIERRE. PARA LA MEJORA DE LA RENTABILIDAD Y DE LA SEGURIDAD DE SERVICIO DE UNA PINZA DE DEMOLICION DE ESTA CLASE, ESTAN FORMADAS LAS HOJAS DE CIZALLA (7,8) EN DIRECCION LONGITUDINAL POR VARIAS PIEZAS Y FIJADAS A LAS MORDAZAS DE LA PINZA (1,2) ADICIONALMENTE POR MEDIO DE SUFRIDERAS (14). ESTAS SUFRIDERAS ESTAN DIRIGIDAS OPUESTAS A LAS SUPERFICIES DE ARRASTRE (13) Y FORMADAS DE TAL MODO QUE SE ABSORBEN LAS FUERZAS DE RESISTENCIA QUE SE PRESENTAN EN LAS CUCHILLAS DE CIZALLA CON EL MOVIMIENTO DE APERTURA DE LA PINZA.
