Abstract

EL INVENTO CONSISTE EN UN PROCEDIMIENTO PARA RETIRAR EL NUCLEO INTERIOR DE PIEZAS FUNDIDAS TRAS ENDURECIMIENTO DEL METAL DE FUNDICION, CON LO QUE LA PIEZA FUNDIDA SE SITUA Y MANTIENE EN UNA MESA DE GOLPEADO Y SEGUIDAMENTE SE FOLPEA CON UN PISON DE UN MARTILLO NEUMATICO EN UNA PARTE DE LA PARED DE LA PIEZA FUNDIDA CON UNA ENERGIA DE GOLPE DETERMINADA HASTA QUE SE PRODUZCA UNA FISURA EN EL NUCLEO EN VARIAS PARTICULAS, CON LO QUE TRAS GOLPEAR LA PIEZA FUNDIDA SE LLEVA TENSA EN UNA MESA VIBRADORA PARA QUE LA PIEZA FUNDIDA SE IMPULSA EN LA MESA VIBRATORIA CON ENERGIA VIBRATORIA DE MODO QUE LA ABRASION DE LA ARENA DE MOLDEO SE TRITURE DE NUEVO POR LA ENERGIA DE VIBRACION Y CON LO QUE TRAS EL VACIADO DE LA PIEZA FUNDIDA SE TRANSPORTE ESTA. UN DISPOSITIVO PARA LLEVAR A CABO EL PROCEDIMIENTO SE CARACTERIZA POR UNA MESA DE GOLPEO SOBRE LA QUE SE COLOCA UN MARTILLO DE AIRE A PRESION CON UN PISON, ASI COMO POR UNA MESA DE VIBRACION CON MEDIOS PARA PRODUCIR LA ENERGIA DE VIBRACION Y MEDIOS PARA TRANSFERIR LA ENERGIA DE VIBRACION A UNA PIEZA FUNDIDA.
