Description

Technical Field

[0001] The utility model relates to the technical field of annealing machines, in particular to a porcelain tube copper wire continuous drawing and annealing machine. Background Art

[0002] Annealing machine is a kind of mechanical equipment widely used in machinery manufacturing, hardware processing, wire and cable and other industries. It is used for drawing metal wires such as copper-clad aluminum wire so that the diameter, roundness, internal metallographic structure, surface finish and straightness of the metal wire meet the raw material processing requirements required for standard parts.

[0003] The efficiency of heating, cooling, and air-drying copper wire affects its quality. Current annealing machines typically utilize cooling rings to cool the wire in one go. While this cooling method is efficient and simple, it can also cause the wire to cool too quickly, leading to poor annealing and affecting wire quality. To address this issue, we developed a porcelain tube copper wire continuous drawing and annealing machine. Utility Model Content
