Abstract

LA INVENCION SE REFIERE A UNA HERRAMIENTA DE EXTRUSION PARA LA PRODUCCION DE UNA BARRA DE METAL DURO O DE CERAMICA CON AL MENOS UN ORIFICIO INTERNO EN HELICE (14). LA BOQUILLA (3) DE LA MATRIZ DE EXTRUSION (2) TIENE UN CANAL CILINDRICO LISO (4). COAXIAL DENTRO DE LA MATRIZ DE EXTRUSION (2) ESTA MONTADO UN PORTADOR (6), EL CUAL DE ACUERDO CON LA CANTIDAD DE ORIFICIOS INTERNOS DESEADOS (14), POSEE HILOS ELASTICOS (9) Y/O CANALES U ORIFICIOS PARA LA INYECCION EN FORMA DE HILOS DE UN MATERIAL PLASTICO EN EL MATERIAL EXTRUIDO. EL PORTADOR (6) COMO TAMBIEN LA BOQUILLA DE LA MATRIZ (3) ESTAN FORMADOS GIRATORIOS, ES DECIR, GIRAN CADA VEZ ALREDEDOR DE SU EJE LONGITUDINAL. POR TANTO, EL ANGULO DEL PASO DE LOS ORIFICIOS INTERNOS PRODUCIDOS EN HELICE (14), SE DETERMINA POR LA VELOCIDAD DE ROTACION DEL PORTADOR DE LOS HILOS (6) Y/O DE LA BOQUILLA DE LA MATRIZ (3) Y LA VELOCIDAD DE CIRCULACION DEL MATERIAL EXTRUIDO. POR CONSIGUIENTE, SE PUEDEN PRODUCIR BARRAS EN BRUTO CON ORIFICIOS INTERNOS EN HELICE (14) DE ELEVADA PRECISION.
