Description

Technical Field

[0001] The utility model relates to the field of extra-thick metal composite plates, and more specifically to a vacuum hot-pressed extra-thick metal composite plate. Background Art

[0002] Metal clad panels are made by laminating one metal layer with another. This approach conserves resources and reduces costs without sacrificing performance (corrosion resistance, mechanical strength, etc.). Common cladding methods include explosive lamination, explosive rolling lamination, and rolling lamination. Composite materials can be categorized by appearance as clad plates, clad pipes, and clad rods. They are primarily used in industries such as corrosion protection, pressure vessel manufacturing, power construction, petrochemicals, pharmaceuticals, light industry, and the automotive industry.

[0003] Extra-thick metal plates are special composite plates whose thickness exceeds the conventional standard thickness. However, due to the large thickness of the two plates, the direct vacuum hot pressing method consumes a lot of energy to combine them. It may also cause some welds to be unstable, resulting in poor structural strength. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a vacuum hot-pressed composite extra-thick metal composite plate.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions.

[0006] A vacuum hot-pressed composite extra-thick metal composite panel comprises two metal panels, opposite sides of the two metal panels are fixedly connected with connecting plates by vacuum hot pressing, opposite sides of the two connecting plates are bonded with films, and a thickening layer is bonded between the opposite sides of the two films.

[0007] As a further description of the above technical solution: the top view cross-section of the thickened layer is honeycomb-shaped.

[0008] As a further description of the above technical solution: the thickened layer is an aluminum alloy layer.

[0009] As a further description of the above technical solution: the film is a high temperature and high pressure resistant metal adhesive.

[0010] Compared with the prior art, the advantages of the present invention are:

[0011] This solution ensures structural strength and increases thickness by thickening layers and films. At the same time, the metal panels and connecting plates are vacuum hot-pressed to ensure connection strength. As a result, the device has the advantages of reducing energy consumption in hot-pressing extra-thick composite panels and being more energy-efficient, while ensuring structural strength.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0019] See also Figures 1 to 4 In the utility model, a vacuum hot-pressed composite extra-thick metal composite panel comprises two metal panels 1, the opposite sides of the two metal panels 1 are fixedly connected with connecting plates 2 by vacuum hot pressing, the opposite sides of the two connecting plates 2 are bonded with films 3, and the opposite sides of the two films 3 are bonded with a thickening layer 4.

[0020] In the present invention, two connecting plates 2 are first fixed on the connecting surfaces of two thicker metal panels 1 by vacuum hot pressing, and then the other sides of the two connecting plates 2 are vertically stacked with films 3 and thickening layers 4, and then high-temperature and high-pressure bonding is performed. The thickness of the finished product is increased, while the weight is reduced, and the high strength of the composite plate is achieved at the same time, so that the device has the advantages of reducing energy consumption and being more energy-efficient in hot pressing of extra-thick composite plates, and ensuring structural strength, which solves the problem in the existing technology that the current extra-thick metal plates consume huge energy when directly vacuum hot pressing due to the large thickness of the two plates, and may also cause some welding to be unstable, resulting in poor structural strength.

[0021] See also Figure 3 and Figure 4 , wherein: the top cross-section of the thickened layer 4 is honeycomb-shaped.

[0022] In the present invention, the top cross-section of the thickened layer 4 is honeycomb-shaped, so that the contact area between the side edges of the thickened layer 4 and the films 3 on both sides is maximized, thereby enhancing the connection stability. At the same time, the honeycomb structural characteristics can reduce the weight of the extra-thick metal composite plate.

[0023] See also Figure 1 , wherein: the thickened layer 4 is an aluminum alloy layer.

[0024] In the present invention, the thickened layer 4 is formed into an aluminum alloy layer, thereby ensuring strength while reducing the weight of the finished product.

[0025] See also Figure 1 , wherein: film 3 is a high temperature and high pressure resistant metal bonding glue.

[0026] In the present invention, the film 3 is a high-temperature and high-pressure resistant metal bonding adhesive, so that after the bonding is cooled, the connection stability of the structure is higher.
