Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, and in particular to a nickel plating device for magnesium alloy surfaces. Background Technology

[0002] The nickel plating apparatus for magnesium alloy surfaces is a device used to plate a layer of nickel onto the surface of magnesium alloys through a specific process. Its purpose is to improve the corrosion resistance, wear resistance, and electrical conductivity of magnesium alloys, while also improving their appearance.

[0003] In some existing nickel plating equipment for magnesium alloys, the lack or inadequacy of stirring or rotating structures presents numerous challenges to the nickel plating process. The absence of an effective stirring or rotating structure means the plating bath remains relatively static. As the plating process continues, the distribution of nickel salts, complexing agents, and additives gradually becomes uneven. For example, nickel salt ions may gradually precipitate to the bottom of the bath under gravity, resulting in an excessively high nickel salt concentration at the bottom and a low concentration at the top. Simultaneously, additives cannot be evenly dispersed throughout the plating bath, hindering their ability to effectively improve the microstructure and gloss of the coating. This unevenly distributed plating bath directly impacts the quality of the nickel plating. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5 A nickel plating device for magnesium alloy surfaces includes a plating bath 1, a lifting frame 3 and a rolling frame 5. The rolling frame 5 is provided with a disassembly plate 6 through an opening and closing port. The opening and closing port can be easily opened and closed by means of the disassembly plate 6, thereby realizing convenient loading and unloading of raw materials to be processed.

[0026] The rolling frame 5 is rotatably mounted on the lifting frame 3. The lifting frame 3 is rotatably equipped with a rotating shaft 9. The outer wall of the plating tank 1 is equipped with a drive motor 13. The drive motor 13 is connected to the rotating shaft 9 through a rotating mechanism. The rotating shaft 9 is connected to the rolling frame 5 through a transmission mechanism. The plating tank 1 is equipped with a movable opening 8. A limiting frame 11 extending into the rotating opening 7 is provided in the movable opening 8 through an elastic mechanism. The limiting frame 11 is T-shaped. The rotating shaft 9 is equipped with an annular groove 10. The lifting frame 3 is equipped with a mounting rod 20. The plating tank 1 is equipped with a mounting groove 18. The outer wall of the mounting rod 20 is equipped with an extrusion groove 21. A positioning block 22 is provided in the extrusion groove 21 through an extrusion mechanism. The plating tank 1 is equipped with a positioning hole 19.

[0027] The rotating mechanism includes a drive gear 14 mounted on the output shaft of the drive motor 13, and a transmission gear 15 meshing with the drive gear 14 on the rotating shaft 9. The transmission mechanism includes a synchronizing gear 16 mounted on the rotating shaft 9, and a gear ring 17 meshing with the synchronizing gear 16 on the rolling frame 5. Relying on the aforementioned drive gear 14, transmission gear 15, synchronizing gear 16, and gear ring 17, the rolling frame 5 can rotate after the drive motor 13 is started.

[0028] The elastic mechanism includes an outer spring 12 disposed within the movable opening 8. The outer spring 12 is sleeved on the outside of the limiting frame 11, with its two ends connected to the outer wall of the head of the limiting frame 11 and the inner wall of the movable opening 8, respectively. The elastic potential energy provided by the outer spring 12 enables the limiting frame 11 to be dragged, ensuring that its rod is within the annular groove 10. In this state, the rotating shaft 9 cannot move horizontally and thus achieves a good limiting effect.

[0029] The extrusion mechanism includes an inner spring 23 disposed within the extrusion groove 21. The two ends of the inner spring 23 are connected to the outer wall of the positioning block 22 and the inner wall of the extrusion groove 21, respectively. The elastic potential energy provided by the inner spring 23 enables the extrusion of the positioning block 22, which can be extruded into the positioning hole 19. At this time, the lifting frame 3 and other components cannot move vertically and are displaced.

[0030] The lifting frame 3 is equipped with a mounting bracket 4. With the support of the mounting bracket 4 and external hoisting equipment, the lifting frame 3 and components such as the rolling frame 5 can be hoisted and moved.

[0031] When using this utility model, such as Figure 1 As shown, the material to be processed is in the rolling frame 5. The plating tank 1, together with the heating component 2 and other equipment components, completes the processing of the material to be processed (the other equipment components are all existing technology equipment components, which will not be described in detail in this solution).

[0032] During the processing, after the drive motor 13 starts, it can drive the drive gear 14 to rotate. The rotation of the drive gear 14 can drive the rotating shaft 9 and the synchronous gear 16 to rotate. The synchronous gear 16, together with the gear ring 17, can drive the rolling frame 5 to rotate. The rotation of the rolling frame 5 can drive the plating solution to flow, so that the nickel salt, complexing agent, additives and other components in the plating solution are more evenly mixed.

[0033] In this scheme, after processing is completed, the drive motor 13 is turned off, and then the positioning block 22 in the positioning hole 19 is pressed to compress the inner spring 23 and enter the extrusion groove 21. Then the vertical limit of the mounting rod 20 is released, and the entire device can be lifted and transferred by means of external hoisting equipment and hanging frame 4. It can be transferred to other areas to facilitate the removal of the product to be processed in the rolling frame 5.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
