Technical Field

[0001] The utility model relates to the technical field of aluminum tube production and processing, and more specifically, to aluminum tube continuous drawing production equipment. Background Art

[0002] Aluminum tube is a kind of non-ferrous metal tube, which refers to a metal tubular material that is made of pure aluminum or aluminum alloy through extrusion and is hollow along its entire longitudinal length. During the production and processing of aluminum tubes, in order to reduce the outer diameter and wall thickness of the aluminum tubes and improve the surface quality and mechanical properties of the aluminum tubes, the aluminum tubes need to be continuously drawn.

[0003] After searching, the Chinese patent with authorization announcement number CN202006223U discloses continuous drawing equipment for aluminum tubes. This structure uses a flat belt in conjunction with a flat belt pulley when drawing the aluminum tube, and has a semicircular groove on the outer side of the belt. A clamping roller with a spring is added to ensure that the aluminum tube does not slip, making the clamping force adjustable, meeting engineering requirements, improving processing efficiency, and reducing production costs.
