Description

Technical Field

[0001] The utility model relates to the technical field of steel wire processing equipment, in particular to a steel wire phosphating device which is convenient for uniform temperature control. Background Art

[0002] Phosphating of steel wire is a surface treatment process, which is usually used to enhance the corrosion resistance and lubricity of metal surfaces. By forming a phosphide film on the metal surface, the wear resistance and corrosion resistance of metal parts can be improved.

[0003] When the steel wire is phosphated, it is usually cleaned and pickled. After cleaning and pickling, the steel wire will be placed in the phosphating tank and contacted with a phosphate solution or a solution containing a phosphating agent. Under appropriate temperature and time conditions, a phosphide film will form on the surface of the steel wire.

[0004] During the phosphating process of the above-mentioned steel wire, it is found that the temperature of the steel wire entering the phosphating pool is usually low. After contacting with the phosphating solution, the temperature of the phosphating solution around the steel wire will decrease, resulting in uneven temperature distribution of the phosphating solution inside the phosphating pool. Uneven temperature will lead to inconsistent phosphating reaction rates. Thicker phosphating films may be formed in some areas, while thinner films may be formed in other areas, resulting in uneven thickness of the phosphating film.

[0005] In summary, there is a need for a device that is easy to evenly control the temperature for phosphating steel wire. Utility Model Content

[0030] In this embodiment, the temperature control mechanism 2 includes a mounting frame 21, a heat conducting plate 1 22, a heat conducting plate 23 and a heating rod 1 24. The mounting frame 21 is fixedly arranged inside the phosphating chamber. The top and bottom surfaces of the mounting frame 21 are provided with a heat conducting plate 1 22 and a heat conducting plate 23. A heating rod 1 24 is provided in the middle of the mounting frame 21. A plurality of heating rods 1 24 are provided inside the mounting frame 21.

The arrangement of the heat conducting plate 1 22 and the heat conducting plate 23 can absorb the heat of the heating rod 1 24 and evenly transfer the heat to the phosphating liquid inside the phosphating chamber.

[0031] In this embodiment, the flow guide component 3 is located at the end of the flow guide area, and the flow guide component 3 is arranged corresponding to the temperature control mechanism 2; the flow guide component 3 is arranged corresponding to the temperature control mechanism 2 to facilitate the phosphating solution to flow inside the flow guide area;

[0032] In this embodiment, the flow guide assembly 3 includes a mounting plate 31 and a fan blade 32. The mounting plate 31 is fixedly arranged at the end of the flow guide area, and a plurality of fan blades 32 are arranged inside the mounting plate 31.
