Abstract

LA INVENCION SE REFIERE A LA FORMACION DE ROSCAS Y PARTICULARMENTE A LA FORMACION DE ROSCAS SOBRE VARILLAS DE REFUERZO DE ACERO, DEFORMADAS. EL METODO DE FORMACION DE UNA ROSCA SOBRE LA VARILLA DE REFUERZO DE ACERO COMPRENDE LOS PASOS DE ACORTAR EN FRIO UNA REGION DEL EXTREMO (1) DE UNA VARILLA DE REFUERZO DE ACERO DEFORMADA QUE TIENE UN DIAMETRO NOMINALMENTE, EL ACORTADO SE EFECTUA PARA INCREMENTAR EL DIAMETRO DE LA REGION DEL EXTREMO HASTA UN NUEVO DIAMETRO ACORTADO MAYOR QUE EL DIAMETRO NOMINAL, ROSCAR LA REGION DEL EXTREMO (1) DE MANERA QUE SE PRODUZCA UNA REGION ROSCADA QUE TENGA UN DIAMETRO MAYOR DE LA ROSCA QUE SEA MAYOR QUE EL DIAMETRO NOMINAL Y UN DIAMETRO MENOR DE LA ROSCA QUE SEA MENOR QUE EL DIAMETRO NOMINAL. LA FORMACION DE LA ROSCA HACE POSIBLE LA PRODUCCION DE CONEXIONES MECANICAS ENTRE PARES DE VARILLAS, LAS CONEXIONES TIENEN UNA RESISTENCIA MAYOR QUE LA DE LAS VARILLAS QUE SON CONECTADAS ENTRE SI.
