The invention discloses an elliptical conical tube drawing process, which is carried out according to the following steps: (1) manufacturing of an elliptical model tube, wherein the elliptical model tube is subjected to casting forming, sandblasting, shot blasting, and quenching and tempering; (2) installation preparation before drawing, namely making the elliptical model tube rotate around the axis, then placing a guide rod with a roller at one end and with pressure head as a machining tool at the other end on a sleeve of a support, and at the initial moment, ensuring that the busbar of the roller of the elliptical model tube is closely attached to and overlaps the busbar, passing through the end of the short axis, of the elliptical model tube; and (3) carrying out extrusion drawing on the tube, namely ensuring that the elliptical model tube and a blank circular tube synchronously rotate from the initial installation position, making the elliptical model tube, the roller, the guide rod and the pressure head as a whole move at constant speed outwards along the radial direction of the blank circular tube, and at the same time, dragging the blank circular tube to move axially at constant speed. The elliptical conical tube drawing process has good forming quality and high processing efficiency, and can realize rapid and stable forming of a longer elliptical conical pipeline.
