Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tin-plated sheet technology, specifically relating to an edge-reinforcing structure for tin-plated sheets. Background Technology
[0002] Tinplate (also known as tinplate) is thin and has a brittle plating. If it is directly subjected to weight or impact after being rolled up, problems such as edge springback, crushing, and tin layer cracking are very likely to occur.
[0003] In existing processes, the reinforcement of rolled edges is to transform single-layer rolled edges into closed or sandwich structures. On-site, solutions such as "double-layer rolled edges, embedded flat steel, embedded steel wire or plastic core" are selected according to the plate thickness / load.
[0004] While the above methods can improve the rigidity of the rolled edge, their buffering capacity is weak. Excessive impact can cause the rolled edge to deform directly, and the inner space of the rolled edge can be damaged by the impact, resulting in corrosion of the zinc layer. This corrosion is difficult to observe, thus affecting the service life. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a rolled edge reinforcement structure for tin-plated thin plates.
[0006] The technical solution adopted to solve the above technical problems is: a rolled edge reinforcement structure for tin-plated thin plates, including a plate body, the side of the plate body is provided with a rolled edge, the inside of the rolled edge is wrapped with a rubber tube, and a protective wire runs through the inside of the rubber tube.
[0007] Furthermore, the side of the rubber cylinder is evenly distributed with multiple through holes, which provide open space through the above-mentioned configuration.
[0008] Furthermore, the interior of the rubber cylinder is filled with zinc-rich paint. Through the above-mentioned configuration, the zinc-rich paint provides protection for the inner side of the rolled edge, thereby preventing rust from occurring on the inner side of the rolled edge that is not easily detected from the outside.
[0009] Furthermore, the protective wire is a steel wire, and the use of steel wire, as described above, can improve the overall structural strength.
[0010] The beneficial effects of this invention are as follows: The presence of a rubber sleeve and protective wire further enhances the overall strength of the rolled edge. When subjected to external impact, the rubber sleeve and protective wire effectively disperse and bear stress, improving the sidewall's resistance to breakage and deformation. Regarding corrosion resistance, the zinc-rich paint plays a crucial role. The zinc-rich paint forms a robust anti-corrosion coating inside the rolled edge, preventing rust caused by zinc layer damage that is difficult to observe on the inside of the rolled edge, thus significantly extending the service life of the tinplate.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0016] like Figures 1 to 3As shown, this embodiment of a rolled edge reinforcement structure for tin-plated thin plates includes a plate body 1, with a rolled edge 2 on the side of the plate body 1, and a rubber cylinder 3 wrapped inside the rolled edge 2. The rubber cylinder 3 is made of rubber, a material with elasticity and flexibility. The properties of rubber allow the rubber cylinder 3 to act as a buffer and filler inside the rolled edge 2. It can adapt to various shape changes of the rolled edge 2 during the forming process, and at the same time, it can also provide a certain support force for the rolled edge 2. A protective wire 4 runs through the inside of the rubber cylinder 3. The protective wire 4 plays a key role in the entire structure, which not only enhances the strength of the rubber cylinder 3, but also has multiple through holes evenly distributed on the side of the rubber cylinder 3. The size and spacing of the through holes can be determined according to the actual use needs and product performance requirements. The existence of the through holes has multiple functions. First, after the inside of the rubber cylinder 3 is filled with zinc-rich paint, these through holes can serve as channels for the zinc-rich paint to flow out. When subjected to external pressure, the zinc-rich paint can flow out evenly through these through holes and fill the gaps inside the rolled edge 2. The inside of the rubber cylinder 3 is filled with zinc-rich paint. Zinc-rich paint is a coating with excellent anti-corrosion properties, containing a large amount of zinc powder. Zinc powder has active chemical properties; when it comes into contact with oxygen and moisture in the air, it undergoes an oxidation reaction before metals such as iron, forming a dense zinc oxide protective film that effectively prevents oxygen and moisture from corroding the plate 1. In this edge-reinforcing structure, zinc-rich paint fills the interior of the rubber cylinder 3, providing additional anti-corrosion protection to the inner side of the edge 2, greatly extending the service life of the tin-plated sheet. The protective wire 4 is made of steel wire. Steel wire has high strength and good toughness, capable of withstanding significant tensile and compressive forces. In the edge-reinforcing structure, the steel wire, as the protective wire 4, runs through the interior of the rubber cylinder 3, enhancing the overall strength of the rubber cylinder 3. When the edge 2 is subjected to external forces, the protective wire 4 can disperse and bear some of the stress, preventing damage to the rubber cylinder 3. Simultaneously, the steel wire has relatively stable chemical properties and is not easily corroded by the zinc-rich paint, maintaining its performance during long-term use.
[0017] The working principle of this embodiment is as follows: When the plate 1 is rolled, in the initial process of rolling, the side of the plate 1 gradually bends, and the initial shape of the rolled edge 2 begins to form. As the rolled edge 2 gradually forms and tends to close, the rubber cylinder 3 is placed inside the rolled edge 2. After the rubber cylinder 3 is placed, the forming process of the rolled edge 2 continues until the rolled edge 2 is completely formed.
[0018] Subsequently, the protective wire 4 is introduced into the rubber cylinder 3. During the introduction of the protective wire 4, the space inside the rubber cylinder 3 is compressed. The zinc-rich paint filling the rubber cylinder 3 is compressed, and because of the evenly distributed through holes on the side of the rubber cylinder 3, the zinc-rich paint can flow out evenly through these through holes, thereby filling the gaps on the inner side of the rolled edge 2. In this process, the outflow of zinc-rich paint is a slow and uniform process, ensuring that every gap inside the rolled edge 2 is fully filled.
[0019] Finally, pressure is applied to the rolled edge 2 to promote its formation, enabling it to achieve the desired shape and size. Simultaneously, during the pressure application process, the zinc-rich paint further fills the interior of the rolled edge 2. The pressure allows the zinc-rich paint to better penetrate the tiny gaps inside the rolled edge 2, forming a denser protective coating, thus effectively protecting the rolled edge 2. The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
