Abstract

EL APARATO SIRVE PARA RECORTAR LOS TUBOS GUIAS DE UN ENSAMBLAJE COMBUSTIBLE POR DEBAJO DE LA CABEZA SUPERIOR. COMPRENDE UN BASTIDOR (28) (36) CON UNOS MEDIOS DE FIJACION AMOVIBLE (42) (44) (46) (48) Y DE CENTRAJE (40) EN LA CABEZA. UNOS UTILES DE CORTE (20) INSERTABLES EN LOS TUBOS GUIAS QUE TIENEN CADA UNO UN HUSILLO HUECO (52) CUYA PARTE FINAL ESTA DIVIDIDA EN UNAS RANURAS LONGITUDINALES (74) EN DEDOS EXPANSIBLES QUE PORTAN UN FILO DE CORTE (76) Y UNA BARRA (58) DESPLAZABLE AXIALMENTE A LO LARGO DEL HUSILLO COOPERANDO CON ESTE PARA DESPLEGAR RADIALMENTE LOS DEDOS Y RETRACTARLES. LOS HUSILLOS (52) ESTAN MONTADOS ROTATIVOS SOBRE UNA PLATAFORMA DESPLAZABLE VERTICALMENTE CON RELACION AL BASTIDOR POR UN GATO (22) Y PORTA UN MOTOR (54) DE ARRASTRE SIMULTANEO EN ROTACION DEL CONJUNTO DE LOS HUSILLOS. LAS BARRAS (58) SON PORTADAS POR UN CONJUNTO DE EXPANSION (24) DESPLAZABLE VERTICALMENTE CON RELACION A LA PLATAFORMA POR UN GATO (26).
