Description

Technical Field

[0001] This utility model relates to the field of galvanizing processing technology, and more specifically, to a galvanizing fixture with an auxiliary anode. Background Technology

[0002] In modern industrial production, galvanizing is widely used for surface protection of various metal products to improve their corrosion resistance and aesthetics. Galvanizing racks, as an indispensable component of this process, directly affect the quality of galvanizing. Traditional galvanizing racks are relatively simple in construction, primarily functioning to suspend the raw material to be galvanized via hooks and achieve electrical connection with the cathode. However, in actual galvanizing operations, this simple design reveals many drawbacks. Firstly, the simple cathode connection makes it difficult to ensure uniform current distribution across the raw material during current transmission, easily leading to inconsistent galvanized layer thickness, severely affecting the product's appearance and protective performance. Secondly, during galvanizing, due to the complex chemical reaction between the solution and the raw material, air pockets often form inside the material. These air pockets act as barriers, hindering sufficient contact between the galvanizing solution and the raw material, resulting in gaps or uneven thickness in the galvanized layer, significantly reducing the overall quality and service life of the product. Therefore, we propose a galvanizing rack with an auxiliary anode to solve these problems. Utility Model Content

[0003] The main purpose of this invention is to provide a galvanizing fixture with an auxiliary anode, which solves the many drawbacks exposed by this simple design in the actual galvanizing process. On the one hand, the simple cathode connection method makes it difficult to ensure that the current is evenly distributed in all parts of the raw material to be plated during the current transmission process. This easily leads to inconsistent zinc coating thickness, which seriously affects the appearance and protective performance of the product. On the other hand, during galvanizing, due to the complex chemical reaction between the solution and the raw material, air pockets often form inside the raw material. The presence of these air pockets acts as a barrier, hindering the full contact between the galvanizing solution and the raw material, which in turn leads to gaps or uneven thickness in the zinc coating, greatly weakening the overall quality and service life of the product.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A galvanizing fixture with an auxiliary anode includes a suspension frame. Several support frames are installed at the rear end of the suspension frame. Several fixed rods are equidistantly installed at the front end of the support frames. Hooks are installed at the front ends of the fixed rods, and raw materials are hung on the hooks. Extension frames are installed at the lower end of the front surface of the support frames. Auxiliary rings are installed at the front ends of the extension frames, and the auxiliary rings are sleeved on the outside of the fixed rods and located inside the raw materials. Limiting frames are installed at the upper ends of the fixed rods, and the upper ends of the limiting frames are in contact with the inner wall of the raw materials, pushing the rear side of the raw materials upwards. Rolling mechanisms are installed at both ends of the support frame, and the rolling mechanisms are in contact with the outer side of the raw materials, with the rolling mechanisms and the limiting frames overlapping vertically.

[0006] Preferably, the rolling mechanism includes a plurality of extension rods, which are movably installed through both ends of the support frame. Insulating rollers are fixedly installed on the outer side of the extension rods at the upper end of the support frame. Rollers are movably installed at the front end of the insulating rollers. The rollers are located at the upper end of the raw material and are in contact with the outer side of the raw material.

[0007] Preferably, each of the insulating rollers has a motor installed inside, and each motor has a rotating shaft installed at its output end. The shaft is movably installed through the front end of the insulating roller, and the front end of the rotating shaft is connected to a roller.

[0008] Preferably, the rotating shaft is located on the outside of the rod inside the insulating roller, and the sealing discs are respectively engaged and installed inside the insulating roller.

[0009] Preferably, a handle is installed at the upper end of each extension rod.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] (1) In this utility model, the integrated design of cathode hook and anode auxiliary ring makes the current distribution in the galvanizing process more uniform, thereby effectively avoiding uneven galvanizing layer thickness or defects caused by uneven current distribution. Then, through the rolling mechanism, the raw material can be rotated in the galvanizing process, so that when the air bag inside the raw material rotates to the upper end and is guided by the limit frame to form an inclined shape, the air bag inside the raw material is discharged outward, thereby making it more uniformly attached to the inner wall of the raw material, ensuring the uniformity and integrity of the overall galvanized layer of the raw material.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0018] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a galvanizing hanger with an auxiliary anode, including a suspension frame 1. Several support frames 3 are installed at the rear end of the internal structure of the suspension frame 1. Several fixed rods 4 are installed at equal intervals at the front end of the support frames 3. Hooks 5 are installed at the front end of the fixed rods 4 respectively. Raw materials 2 are hung on the hooks 5 respectively. Extension frames 6 are installed at the lower end of the front surface of the support frame 3 respectively. Auxiliary rings 7 are installed at the front end of the extension frames 6 respectively. The auxiliary rings 7 are sleeved on the outside of the fixed rods 4 and are located inside the raw materials 2 respectively. Limiting frames 8 are installed at the upper end of the fixed rods 4 respectively. The upper end of the limiting frames 8 is in contact with the inner wall of the raw materials 2 respectively. The upper end of the limiting frames 8 pushes the rear side of the raw materials 2 to tilt upward respectively. Rolling mechanisms 9 are installed at both ends of the internal structure of the support frame 3 respectively. The rolling mechanisms 9 are in contact with the outside of the raw materials 2 and overlap vertically with the limiting frames 8.

[0019] like Figure 4As shown, in another embodiment of this utility model, the rolling mechanism 9 includes a plurality of extension rods 901. The extension rods 901 are movably installed through both ends of the support frame 3. Insulating rollers 902 are fixedly installed on the outer side of the extension rods 901 at the upper end of the support frame 3. Rollers 903 are movably installed at the front end of the insulating rollers 902. The rollers 903 are located at the upper end of the raw material 2 and are in contact with the outer side of the raw material 2. Motors 904 are installed inside the insulating rollers 902. Rotating shafts 905 are installed at the output end of the motors 904. The shaft of the rotating shaft 905 is movably installed through the front end of the insulating roller 902. The front end of the rotating shaft 905 is connected to the rollers 903. Sealing discs 906 are installed on the outer side of the shaft of the rotating shaft 905 inside the insulating roller 902. The sealing discs 906 are respectively engaged inside the insulating roller 902. Handles 907 are installed on the upper end of the extension rods 901.

[0020] The user hangs the raw material 2 using hook 5, ensuring its inner wall aligns with the upper end of the limiting frame 8, thus tilting the material 2. The user then pulls the extension rod 901 upwards using handle 907, causing the roller 903 to move upwards, temporarily separating the roller 903 from the surface of the raw material 2. The user can then place the hanging frame 1 into the galvanizing bath. Hook 5 connects to the cathode, and auxiliary ring 7 connects to the auxiliary anode, integrating the cathode and anode into one unit. This results in a more uniform current distribution during the galvanizing process, effectively preventing problems caused by uneven current distribution. If the galvanized layer is uneven or defective, and it is necessary to control the rotation of the raw material 2, the user only needs to move the handle 907 downward, so that the handle 907 drives the extension rod 901 and the roller 903 to move, so that the roller 903 is in contact with the surface of the raw material 2. Then the motor 904 can drive the rotating shaft 905 and the roller 903 to rotate, so that the roller 903 drives the raw material 2 to rotate slowly around the hook 5 as the axis. Then, after the air bag on the inner wall of the raw material 2 rotates to the upper end, it is pushed outward in an inclined manner by the limit frame 8, so that the galvanized layer on both the inner and outer sides of the raw material 2 is more complete and uniform.

[0021] The working principle of this type of galvanizing rack with auxiliary anode:

[0022] In use, the user first hangs the raw material 2 using the hook 5, ensuring the inner wall of the raw material 2 is in contact with the upper end of the limiting frame 8, thus tilting the raw material 2. Then, the user pulls the extension rod 901 upwards using the handle 907, causing the extension rod 901 to move the roller 903 upwards, temporarily separating the roller 903 from the surface of the raw material 2. The user then places the hanging frame 1 into the galvanizing bath. The hook 5 connects to the cathode, and the auxiliary ring 7 connects to the auxiliary anode, integrating the cathode and anode into one unit. This results in a more uniform current distribution during the galvanizing process, effectively preventing uneven current distribution. This can lead to uneven or defective galvanized layer thickness. When it is necessary to control the rotation of the raw material 2, the user only needs to move the handle 907 downward, so that the handle 907 drives the extension rod 901 and the roller 903 to move, so that the roller 903 is in contact with the surface of the raw material 2. Then the motor 904 can drive the rotating shaft 905 and the roller 903 to rotate, so that the roller 903 drives the raw material 2 to rotate slowly around the hook 5 as the axis. Then, after the air bag on the inner wall of the raw material 2 rotates to the top, it is pushed outward in an inclined manner by the limit frame 8, so that the galvanized layer on both the inner and outer sides of the raw material 2 is more complete and uniform.

[0023] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
