Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA EL CURVADO DE TUBOS DE PLASTICOS EN DONDE UN TUBO DE PLASTICO ES CALENTADO EN EL PUNTO DE DOBLADO. LA CARACTERISTICA DE LA INVENCION ES QUE LAS SECCION DEL TUBO SE CALIENTAN PRIMERO EN BAÑO DE AGUA A APROXIMADAMENTE 80 LTIPLES PLACAS (3) DE DOBLADO DEPENDIENDO DEL PERFIL DESEADO, DONDE LAS PLACAS DE DOBLADO ESTAN SOMETIDAS A UNA FUENTE (5) DE CALOR, POR EJEMPLO A UN SOPLADOR DE AIRE CALIENTE Y CALENTADAS PARCIALMENTE, DEPENDIENDO DEL MATERIAL DEL TUBO USADO, HASTA UN MAXIMO DE 160 LA SECCION DEL TUBO SE SOMETE A UN PRIMER PROCESO DE ENFRIAMIENTO A PARTIR DEL INTERIOR UTILIZANDO AIRE (24) COMPRIMIDO FRIO DESDE 10 HASTA 15 SEGUNDOS Y FINALMENTE LA SECCION DEL TUBO SE COLOCA EN UN BAÑO DE AGUA FRIA. LA INVENCION SE REFIERE TAMBIEN A UN DISPOSITIVO PARA LA IMPLANTACION DEL PROCESO.
