Abstract

EL AJUSTE DE LOS BORDES ENTRE LOS BORDES OPUESTOS (5,8) DE UNA MATRIZ DE EXTRUSION (1) COMPUESTA POR AL MENOS DOS CUERPOS (2,3) MONTADOS JUNTOS, TERMINANDO CADA UNO CON UNA PARTE DE BORDE, SIENDO AL MENOS UNO DE ESTOS (5) ELASTICAMENTE FLEXIBLE, SE REALIZA INSTALANDO UN TORNILLO (10) MONTADO CON ROTACION EN EL BORDE FLEXIBLE (5) SOBRE PLACAS LATERALES, QUE SE DIVIDE EN UNA SEMIPARTE QUE TIENE UN FILETEADO EN EL SENTIDO DE LAS AGUJAS DEL RELOJ (10A) Y EN UNA PARTE QUE TIENE UN FILETEADO EN EL SENTIDO INVERSO AL DE LAS AGUJAS DEL RELOJ (10B). UNO O MAS BLOQUES DE FILETEADO (11) ESTAN ACOPLADAS SOBRE DICHAS DOS SEMIPARTES DEL TORNILLO Y POR LO TANTO SE DESLIZAN EN DIRECCIONES MUTUAMENTE OPUESTAS AL GIRAR EL TORNILLO EN LA DIRECCION DE LAS AGUJAS DEL RELOJ O A LA INVERSA. CADA BLOQUE (11) TIENE UNA PARTE DE GUIA (13), FUNCIONALMENTE PARALELA AL EJE DEL TORNILLO (10), Y UNA PATILLA (12) QUE PENETRA EN UNA RANURA RESPECTIVA DE UNA PLURALIDAD DE RANURAS (19A,19B) COORDINADAMENTE INCLINADA EN UNA DIRECCION MUTUAMENTE OPUESTA DE UNA PLACA DE EMPUJE (17) QUE ESTA FIJADA RIGIDAMENTE AL BORDE FLEXIBLE (5). AL GIRAR EL TORNILLO (10) EN UNA U OTRA DIRECCION, EL BORDE FLEXIBLE (5) SE ACERCA O ALEJA DEL BORDE OPUESTO (8). EL DISPOSITIVO MINIMIZA LA CONCENTRACION DE TENSIONES Y SE REALIZA FACILMENTE.
