Abstract

Procedimiento y aparato para el ajuste de extremos de tubos; con el fin de obtener un requerido diámetro interior, así como un requerido diámetro exterior en el extremo del tubo a ajustar caracterizado porque el extremo del tubo es calentado hasta una temperatura de forja, sujetándose el tubo en una parte del mismo que se encuentra alejada de su extremo, con el fin de sostener el tubo estacionario durante la operación de ajuste, introduciéndose a continuación en el extremo del tubo un mandril cuyo diámetro es igual al requerido diámetro interior de dicho extremo, colocándose forzadamente sobre el extremo del tubo y en dirección da la parte sujetada de dicho tubo; un dado o troquel de ajuste de una sola pieza, el que tiene tal cavidad que limita el diámetro exterior del extremo del tubo a ajustar al requerido diámetro exterior, aplicándose una fuerza de compresión longitudinal sobre el extremo del tubo, con el fin de ajustar el mismo, y que finalmente se retira al dado o troquel de ajuste endirección contraria a la zona sujetada del tubo mientras que el último permanece sostenido de forma estacionaria.
