[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral molding; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] See Figures 1-8 , Figure 11 As shown, a zinc-dip welding fixture for metal woven mesh provided according to an embodiment of this application is schematically illustrated, including: a main frame 100 and a capping assembly 300.

[0043] The main frame 100 has an inner section 101 for placing the product to be zinc-treated. A partition 200 for supporting the product is provided within the section 101. Multiple first through holes 102 for zinc powder to pass through are provided on the inner walls of the section 101, and multiple second through holes 201 for zinc powder to pass through are provided on the partition 200. A pressure cap assembly 300 is detachably connected to the main frame 100 to secure the product within the section 101. The main frame 100 can be a hollow rectangular frame or a frame of other shapes, and the multiple second through holes 201 on the partition 200 can be evenly distributed in multiple rows and columns.

[0044] The metal woven mesh to be zinc-distilled is positioned in the placement area 101 inside the main frame 100. Multiple metal woven meshes can be stacked in the placement area 101. The partition 200 in the placement area 101 supports the bottom layer of metal woven mesh. Then, the pressure cap assembly 300 is installed on the main frame 100, and the pressure cap assembly 300 presses down on the top layer of metal woven mesh in the placement area 101, thus fixing the metal woven mesh in the placement area 101 of the main frame 100. Then, the entire fixture is placed into a zinc-distillation furnace or other zinc-distillation equipment. The fixture rotates in the furnace and zinc powder is sprayed onto the fixture for zinc distillation. During the zinc distillation process, the partition 200 can stably support the metal woven mesh. Moreover, the first through hole 102 on the inner sidewall of the placement area 101 and the second through hole 201 on the partition 200 can improve the fluidity of the zinc powder and the uniformity of zinc distillation. After the fixture is removed from the furnace, it is also easy to remove the zinc powder from the fixture, which facilitates the disassembly and cleaning of the fixture, thereby improving the zinc distillation effect and efficiency.

[0045] Therefore, the zinc diffusion fixture for metal woven mesh of this application has a partition plate 200 that can stably support the metal woven mesh. The first through hole 102 on the inner sidewall of the placement section 101 and the second through hole 201 on the partition plate 200 can improve the fluidity of zinc powder and the uniformity of zinc diffusion. Moreover, after the fixture is removed from the furnace, it can also prevent zinc powder or other impurities from accumulating in the fixture, which facilitates the disassembly and cleaning of the fixture. It is easy to operate, has high safety, stability and reliability, improves production efficiency and product yield, and reduces costs.

[0046] In some embodiments, reference Figures 3-6 , Figure 11 As shown, the placement section 101 extends through the main frame 100. The partition 200 is located in the middle of the placement section 101 and is connected to the inner walls of the placement section 101. The partition 200 divides the placement section 101 into two areas. There are two capping assemblies 300. Figure 3 , Figure 4 For reference, the partition 200 divides the placement area 101 into two symmetrical feeding areas, enabling bilateral feeding. After the metal woven mesh is placed in the two feeding areas, the two capping assemblies 300 fix the metal woven mesh in the two feeding areas respectively. As a result, the structure is more compact and stable, and efficiency is also improved.

[0047] In some embodiments, reference Figure 1 , Figure 2 As shown, lifting components 400 are provided on the outer side of the main frame 100. The lifting components 400 can be lifting lugs, hooks, rings, etc., and there can be two lifting components 400 symmetrically arranged at one end of the main frame 100. This facilitates the overall lifting and transportation of the tooling.

[0048] In some embodiments, reference Figure 1 , Figure 2 As shown, a limiting plate 500 is provided on the outer side of the main frame 100. The limiting plate 500 is used for limiting movement in zinc diffusion equipment such as high-temperature zinc diffusion furnaces. Figure 2 For reference, three limiting plates 500 are respectively provided on the left and right sides of the main frame 100 along its length. The limiting plates 500 can be connected to the main frame 100 by welding or screws. This facilitates more stable zinc diffusion of the tooling in the zinc equipment, making it safer and more reliable.

[0049] In some embodiments, reference Figure 2 As shown, the main frame 100 and the pressure cap assembly 300 are detachably connected by a plurality of fasteners 600. Both the main frame 100 and the pressure cap assembly 300 are provided with connection holes for mating with each fastener 600. (Reference) Figure 12 As shown, the fastener 600 includes a bolt 601 and a cap nut 602 that mates with the bolt 601. Thus, the cap nut 602 prevents zinc powder from entering the threads and causing jamming during assembly and disassembly, ensuring smoother assembly and disassembly.

[0050] In some embodiments, reference Figure 5 , Figure 6 As shown, the main frame 100 includes multiple first side frames 103 connected in sequence, which together form a placement area 101. Each first side frame 103 has multiple sets of first through holes 102 arranged sequentially along its length. (Reference) Figures 3-5 As shown, each first frame 103 has a C-shaped cross-section perpendicular to its length, with the C-shaped opening facing outwards from the placement area 101. For example, the first frame 103 can be made of C-shaped steel. One end of the lifting component 400 can be connected to the C-shaped groove of the first frame 103, and the other end of the lifting component 400 is provided with a lifting hole and extends outwards from the C-shaped groove. For example, the main frame 100 includes four first frame 103s, each made of C-shaped steel. The four C-shaped steels form a hollow rectangular frame, within which is the placement area 101. The C-shaped openings of the four C-shaped steels all face outwards from the placement area 101, and the web height of the C-shaped steel is the height of the first frame 103. Therefore, the structure is simple, stable, small in size, and easier to operate.

[0051] Further, refer to Figure 5 , Figure 6 As shown, the first through hole 102 is an oblong hole extending along the height direction of the first frame 103. A fifth through hole 106 for zinc powder to pass through is provided at the connection point of two adjacent first frame members 103. This further improves the fluidity of the zinc powder and the uniformity of zinc penetration, and also better prevents zinc powder from accumulating in the tooling.

[0052] Further, refer to Figures 5-8 As shown, each first frame 103 is provided with a third through hole 104 connected to the partition 200. The partition 200 is provided with a connecting part 202 corresponding to each third through hole 104. The third through hole 104 is an elongated hole extending along the length direction of the first frame 103. Fourth through holes 105 for zinc powder to pass through are respectively provided on both sides of the length direction of the third through hole 104. Multiple third through holes 104 are sequentially provided along the length direction of each first frame 103, and multiple sets of first through holes 102 and multiple third through holes 104 on each first frame 103 are arranged alternately. This not only ensures the connection strength between the partition 200 and the main frame 100, making the structure more compact and stable, but also improves the fluidity of zinc powder and the uniformity of zinc penetration, preventing zinc powder from accumulating in the tooling.

[0053] In some embodiments, reference Figure 9 , Figure 10 As shown, the capping assembly 300 includes a cover plate 310 and a limiting pressure plate 320. The cover plate 310 is detachably connected to the main frame 100, and the limiting pressure plate 320 is connected to the cover plate 310. The limiting pressure plate 320 corresponds to the placement area 101 to fix the product. The limiting pressure plate 320 has multiple sixth through holes 321 for zinc powder to pass through. The multiple sixth through holes 321 on the limiting pressure plate 320 can be evenly distributed in multiple rows and columns, making the limiting pressure plate 320 a flat, thin mesh structure. The size of the limiting pressure plate 320 can be slightly smaller than the size of the placement area 101. Therefore, it not only stably fixes the metal woven mesh in the placement area 101, but also improves the flowability of the zinc powder and the uniformity of zinc penetration, preventing zinc powder from accumulating in the tooling.

[0054] Further, refer to Figure 9 , Figure 10 As shown, the cover plate 310 is a frame structure that matches the main frame 100, meaning that the planar dimensions of the cover plate 310 and the main frame 100 are basically the same, for example, both are hollow rectangular frames. The cover plate 310 includes multiple second side frames 311 connected in sequence. The cross-section of each second side frame 311 perpendicular to its length direction is L-shaped, such as L-shaped angle steel. The limiting pressure plate 320 is located on the outside of the side of the cover plate 310 facing the main frame 100. Connecting plates 330 are respectively provided on the outer perimeter of the limiting pressure plate 320. Each connecting plate 330 is connected to its corresponding second side frame 311. The limiting pressure plate 320 can extend into the placement interval 101, and a gap is formed between the connecting plate 330 and the inner sidewall of the placement interval 101. Each connecting plate 330 extends along the length direction of the second side frame 311 it is connected to, and multiple seventh through holes 331 for zinc powder to pass through are sequentially provided on each connecting plate 330 along its length.

[0055] For example, refer to Figure 9 , Figure 10 As shown, the cover plate 310 includes four second frame plates 311, each of which is an L-shaped angle steel. The four L-shaped angle steels form a hollow rectangular frame. The limiting pressure plate 320 is a rectangular flat plate, and the size of the limiting pressure plate 320 is slightly smaller than the inner hole size of the rectangular frame. There are four long strip connecting plates 330. One long side of each of the four connecting plates 330 is connected to one of the four sides of the limiting pressure plate 320, and the other long side of each of the four connecting plates 330 is connected to one of the four second frame plates 311. After the cover plate 310 is connected to the main frame 100, the limiting pressure plate 320 and a portion of each connecting plate 330 extend into the placement interval 101, making the structure more compact and stable. Moreover, a gap is formed between the connecting plate 330 and the inner wall of the placement interval 101. Each connecting plate 330 is provided with multiple seventh through holes 331 along its length for zinc powder to pass through, which can also improve the fluidity of zinc powder and the uniformity of zinc penetration, and prevent zinc powder or other substances from accumulating in the tooling.

[0056] In some embodiments, reference Figure 9 , Figure 10 As shown, the cover plate 310 also has a first reinforcing rib 340 and a second reinforcing rib 350 within its frame. The two ends of the first reinforcing rib 340 and the two ends of the second reinforcing rib 350 along their length are connected to the inner sidewall of the cover plate 310 and / or the corresponding connecting plate 330, respectively. The first reinforcing rib 340 and the second reinforcing rib 350 are perpendicular to and staggered, and are connected to the limiting pressure plate 320. The first reinforcing rib 340 can be multiple ribs spaced apart longitudinally along the cover plate 310, and the second reinforcing rib 350 can be multiple ribs spaced apart transversely along the cover plate 310. Angle steel can also be used for both the first and second reinforcing ribs 340 and 350. This improves the structural strength of the cover assembly 300, ensuring a more stable and secure clamping of the metal woven mesh onto the main frame 100.

[0057] In some embodiments, reference Figure 11 As shown, the zinc diffusion fixture for metal woven mesh of this application also includes multiple stops 700. The multiple stops 700 are detachably connected within the placement area 101, thereby adjusting the size of the placement area 101. The stops 700 can also be multiple sets of different sizes, each corresponding to a different size of metal woven mesh. Therefore, by selecting different sizes of stops 700 according to different sizes of metal woven mesh, the fixture can be applied to metal woven mesh of different specifications, expanding its applicability. Furthermore, each stop 700 is provided with an eighth through hole for zinc powder to pass through, which facilitates improved fluidity of the zinc powder and uniformity of zinc diffusion, preventing the accumulation of zinc powder or other substances within the fixture.

[0058] Based on the various embodiments of this application described above, in the absence of explicit denial or conflict, the technical features of one embodiment may be advantageously combined with one or more other embodiments.

[0059] The above descriptions are merely some embodiments of this application, used only to illustrate the technical solutions of this application, and not to limit it. It should be understood that those skilled in the art can make improvements or substitutions based on the above descriptions without departing from the inventive concept of this application, and all such improvements and substitutions should fall within the protection scope of this application. In this case, all details can be replaced with equivalent elements, and materials, shapes, and sizes can also be arbitrary.
