Description

Technical Field

[0001] The present application relates to the technical field of composite aluminum plates, and specifically to a high-strength composite aluminum plate. Background Art

[0002] A composite aluminum plate is an aluminum plate composed of multiple layers of materials, usually composed of an aluminum alloy and other materials (such as steel, titanium, etc.).

[0003] After retrieval, the publication number is CN220298009U, which discloses a high-strength composite aluminum plate, including a first aluminum plate. A first adhesive is fixedly connected to the middle position at the top of the first aluminum plate. Uniformly distributed honeycomb blocks are arranged at the top position of the first adhesive. A second adhesive is arranged at the top position of the honeycomb blocks. An aluminum corrugated core is arranged at the top position of the second adhesive. A steel plate is fixedly connected to the top position of the aluminum corrugated core. An asbestos board is fixedly connected to the top position of the steel plate. Reinforcing ribs are arranged at the top position of the asbestos board. In the present utility model, first, the sealing member and the waterproof member are fixedly connected to the first aluminum plate and the second aluminum plate, enhancing the strength of the composite aluminum plate and preventing the composite plate from being bent and fractured due to external impact. The connection strength between layers is improved through the honeycomb blocks, steel plates, reinforcing ribs, and aluminum corrugated core, which is beneficial to improving the stability of the overall structure of the composite aluminum plate.

[0004] However, since the composite plate structure contains multiple different materials such as aluminum, steel, asbestos, etc., these additional layers and components will increase the weight of the overall composite plate. For some application fields that require lightweight, this design may not be ideal. Moreover, due to the relatively complex structure of the composite plate and the connections between many different materials, there is a risk of deformation or distortion. Especially when subjected to external impact or stress, the connection strength between layers may not be able to fully resist deformation, resulting in an impact on the stability of the overall structure of the composite plate.

[0005] Therefore, it is necessary to provide a high-strength composite aluminum plate to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of the present application, and therefore, it may include information that does not constitute the prior art. Summary of the Utility Model

[0007] The purpose of the present utility model is to provide a high-strength composite aluminum plate to solve the problems raised in the above background art.

[0008] The technical solution adopted by the present application to solve its technical problems is:

[0009] A high-strength composite aluminum plate includes a steel plate and a titanium plate. A plurality of convex frames are integrally formed on the top surface of the steel plate. The convex frames and the surface of the steel plate form a plurality of connecting grooves. Inner sunken grooves are formed on the bottom surface of the titanium plate. A plurality of convex blocks are integrally formed in the inner sunken grooves. After the plurality of convex blocks are respectively inserted into the plurality of connecting grooves, the titanium plate and the steel plate are explosively welded into one body;

[0010] Aluminum is poured on the surfaces of the titanium plate and the steel plate after explosion welding.

[0011] Preferably, the convex frames are in a hexagonal structure, and the plurality of convex frames form a honeycomb structure on the surface of the steel plate.

[0012] Preferably, the convex blocks are hexagonal blocks, and the area of the hexagonal blocks is smaller than the area of the connecting grooves in the convex frames.

[0013] Preferably, three vertical plates and a plurality of horizontal plates are integrally formed on the top surface of the titanium plate. The vertical plates, the horizontal plates and the top surface of the titanium plate enclose a plurality of grooves.

[0015] Preferably, the bottom surface of the steel plate is arranged in the same way as the horizontal and vertical plates on the top surface of the titanium plate.

[0016] The beneficial effects of this application are as follows:

[0017] The convex frames form a honeycomb structure, which has the characteristics of energy absorption performance, light weight and high strength, and can reduce the impact of external shocks on the structure. In addition, there are grooves formed by vertical plates and horizontal plates on the top surface of the titanium plate. The addition of vertical plates and horizontal plates can improve the strength and anti-deformation ability of the composite aluminum plate, contribute to the tight combination of the aluminum plate with the steel plate and the titanium plate, and improve the strength and hardness of the composite aluminum plate to meet the strength requirements during use.

[0034] In order to enable those skilled in the art of this technology to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.

[0035] Please refer to Figures 1-5 , the embodiments provided by the present utility model:

[0036] A high-strength composite aluminum plate, including a steel plate 2 and a titanium plate 3. A plurality of convex frame bodies 21 are integrally formed on the top surface of the steel plate 2. The convex frame bodies 21 and the surface of the steel plate 2 form a plurality of connecting grooves 22. Inner sunken grooves 31 are formed on the bottom surface of the titanium plate 3. A plurality of convex blocks 32 are integrally formed in the inner sunken grooves 31. After the plurality of convex blocks 32 are respectively inserted into the plurality of connecting grooves 22, the titanium plate 3 and the steel plate 2 are explosively welded into one body;

[0037] Specifically, the convex frame 21 has a hexagonal structure. A plurality of convex frames 21 form a honeycomb structure on the surface of the steel plate 2. The honeycomb structure can effectively absorb and disperse impact force and vibration energy, has good energy absorption performance, can reduce the influence of external impact on the structure, has a large volume-to-surface area ratio, and thus has the characteristics of light weight, low density and high strength. The convex block 32 is a hexagonal block, and the area of the hexagonal block is smaller than the area of the connection groove 22 in the convex frame 21.

[0038] Thus, after the explosion welding of the steel plate 2 and the titanium plate 3, they can be tightly connected together to prevent separation during long-term use.

[0039] Aluminum material 1 is poured on the surfaces of the titanium plate 3 and the steel plate 2 after explosion welding. Three vertical plates 4 and a plurality of horizontal plates 5 are integrally formed on the top surface of the titanium plate 3. The vertical plates 4, the horizontal plates 5 and the top surface of the titanium plate 3 enclose a plurality of grooves 6. The three vertical plates 4 and the plurality of horizontal plates 5 are equidistantly arranged on the top surface of the titanium plate 3. The bottom surface of the steel plate 2 is arranged in the same way as the horizontal plates 5 and the vertical plates 4 on the top surface of the titanium plate 3.

[0040] Through the vertical plates 4, the horizontal plates 5 and the grooves 6 formed by the surfaces of the steel plate 2 and the titanium plate 3, after the aluminum material 1 is poured on the surfaces of the titanium plate 3 and the steel plate 2, it can be closely combined with the steel plate 2 and the titanium plate 3 to form a composite aluminum plate.

[0041] On the other hand, the addition of the vertical plates 4 and the horizontal plates 5 can also effectively improve the strength and anti-deformation ability of the formed composite aluminum plate. Coupled with the combination of the convex frames 21 with a honeycomb structure and the convex blocks 32 with a hexagonal shape between the steel plate 2 and the titanium plate 3, it further improves the strength and hardness of the composite aluminum plate, thus ensuring the strength requirement of the aluminum plate during use.

[0042] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
