Abstract

LA INVENCION SE REFIERE A UN TORNILLO PRODUCIDO POR LAMINADO EN FRIO, DISEÑADO PARA ATORNILLARSE EL MATERIAL PLASTICO, Y QUE TIENE UNA ROSCA AUTORROSCANTE, CUYOS FILETES ESTAN FORMADOS, VISTOS EN SECCION, COMO UNA HOJA DE CUCHILLO. LA SUPERFICIE DE LOS LADOS DE LOS FILETES INCORPORA UNA CURVA HACIA EL INTERIOR EN SU TERCIO CENTRAL Y FORMA UN ANGULO EN EL FLANCO EXTERIOR DE LA ROSCA DE APROXIMADAMENTE 30°C (ENTRE LA CURVA Y LA PUNTA DE LA ROSCA) ASI COMO UN ANGULO DEL FLANCO INTERIOR DE LA ROSCA (ENTRE LA CURVA Y LA RAIZ DE LA ROSCA), MIENTRAS QUE EL ANGULO DEL FLANCO INTERIOR DE LA ROSCA DE LA PARTE CENTRAL ES PRACTICAMENTE IGUAL O MAYOR A UN TERCIO DEL ANGULO DEL FLANCO EXTERIOR DE LA ROSCA. LA INVENCION SE REFIERE IGUALMENTE A UN TORNILLO EN EL QUE EL REVESTIMIENTO DEL CUERPO ACTUA COMO GUIA PARA ATORNILLAR DICHO TORNILLO EN UN ORIFICIO, MIENTRAS QUE EL EXTREMO DE LA ROSCA PRESENTA, POR UNA PARTE, UNA ZONA DE EXTREMO QUE TIENE UN BORDE CORTANTE PARA CORTAR SU CANAL DE TORNILLO Y ORIENTARSE OBLICUAMENTE EN RELACION CON LA DIRECCION RADIAL DEL TORNILLO Y, POR OTRA PARTE, UNA LINEA BASE QUE CONTINUA LA BASE DE LA ROSCA SITUADA ENTRE UN FLANCO DE LA ROSCA Y EL REVESTIMIENTO DEL CUERPO, Y CORRE EN DIRECCION ESPIRAL AL TORNILLO, SIGUIENDO UN ANGULO QUE SE DESVIA APROXIMADAMENTE EN 90°, MIENTRAS QUE EL BORDE CORTANTE SE EXTIENDE HASTA CONVERTIRSE EN LA CRESTA O VERTICE DE LA ROSCA.
