Abstract

LA INVENCION SE REFIERE A UNA DISPOSICION (34) DE TOBERAS PARA CORTE CON RAYO LASER DISPONIENDO DE UN CUERPO (10) DE TOBERA EN FORMA DE CONO TRUNCADO, ADAPTANDO AL RAYO LASER ENFOCADO CON UNA PERFORACION (11) DE PASO PARA EL RAYO LASER, CON UN CASQUILLO (13) DE TOBERA RODEADO CONCENTRICAMENTE POR EL CUERPO (10) DE TOBERA Y FORMANDO ASI UN ESPACIO (12) ANULAR, TENIENDO EL INDICADO CASQUILLO UNA PERFORACION (14) DE SALIDA COAXIAL CON LA PERFORACION (11) DE PASO PARA UNA CORRIENTE DE GAS DE CORTE A PARTIR DEL ESPACIO (12) ANULAR CONECTADO A UNA FUENTE DE GAS, EN DONDE LA PERFORACION (14) DE SALIDA SE DISPONE ENFRENTE DE LA PERFORACION (11) DE PASO SOBRE EL LADO DE LA PIEZA DE TRABAJO Y TIENE UN DIAMETRO (D) QUE EXCEDE EL DIAMETRO (D) DE LA PERFORACION (11) DE PASO. PARA ASEGURAR QUE LA CORRIENTE DE GAS ES REFLEJADA A PARTIR DE LA TOBERA DE FORMA PARALELA CON RESPECTO AL EJE DEL RAYO LASER CON UN MINIMO DE PERDIDAS DE FLUJO, LA DISPOSICION DE TOBERAS ESTA DISEÑADA DE TAL MODO, QUE LA SECCION TRANSVERSAL DE LA PERFORACION (14) DE SALIDA ES APROXIMADAMENTE LA MISMA QUE LA SECCION TRANSVERSAL DE TRANSICION ENTRE EL ESPACIO (12) ANULAR Y LA PERFORACION (14) DE SALIDA.
