Aluminum alloy sheet having strong tensile properties

Abstract

This utility model relates to the field of aluminum alloy plate technology, and more particularly to an aluminum alloy plate with strong tensile strength. It includes an aluminum alloy plate body, with multiple square support plates arrayed inside the body. Ribs connected to the inner walls of both sides of the aluminum alloy plate body are fixed to the four corners of each square support plate. X-shaped reinforcing beams that uniformly distribute stress are installed on the aluminum alloy plate body. This utility model uses the square support plates and ribs to form a multi-cavity irregular structure, which improves the bending and torsional strength of the aluminum alloy plate body. The staggered reinforcing ribs further enhance the overall strength. The X-shaped reinforcing beams divide the aluminum alloy plate into four triangular sections, effectively constraining the internal deformation of the aluminum alloy plate under stress, preventing a decrease in overall strength due to local instability, and resulting in more uniform stress distribution. Furthermore, the aluminum alloy plate is mostly hollow, making it lighter and more tensile-resistant compared to solid-filled aluminum alloy plates.

Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy plate technology, and in particular to an aluminum alloy plate with strong tensile strength. Background Technology

[0002] For example, Chinese patent CN218881405U discloses a new type of aluminum alloy plate with high tensile strength. By combining tensile reinforcing mesh, reinforcing plate and several stainless steel reinforcing ribs, the interior of the aluminum alloy plate is formed into several equally sized triangles, and the included angle between adjacent reinforcing ribs is 120°. Since triangles have strong stability, they can improve the structural strength and tensile performance of the aluminum alloy plate, making the aluminum alloy plate more durable and less prone to deformation.

[0003] However, the above scheme uses dissimilar metals (such as stainless steel and aluminum alloy) as reinforcing components, which are prone to interface failure due to electrochemical corrosion, weakening the overall structure and reducing tensile strength. In addition, the included angle design of the triangular support unit lacks mechanical optimization. If the included angle is too large, it will result in insufficient buckling resistance and cannot effectively disperse stress, making it prone to local deformation or fracture under high load. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an aluminum alloy plate with strong tensile strength, solving the technical problem that the triangular support unit setting in existing aluminum alloy plates lacks mechanical optimization, cannot effectively disperse stress, and is prone to local deformation or fracture under high loads.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an aluminum alloy plate with strong tensile strength, comprising an aluminum alloy plate body, multiple square support plates arranged in an array inside the aluminum alloy plate body, and ribs connected to the inner walls of both sides of the aluminum alloy plate body are fixed at the four corners of the square support plates, forming a multi-cavity irregular structure with tensile and torsional resistance. A through hole is opened through the center of the square support plate to disperse stress. An X-shaped reinforcing beam for uniformly dispersing stress is installed on the aluminum alloy plate body, and reinforcing ribs for increasing strength are interlaced between adjacent ribs. A T-shaped connecting block is installed on the side of the aluminum alloy plate body, and a concave connecting seat adapted to the T-shaped connecting block is installed on the other side.

[0006] A further improvement is that the through hole is a regular hexagonal structure, and the square support plate and four ribs form an X-shaped structure within the aluminum alloy plate body.

[0007] A further improvement is that the X-shaped reinforcing beam cuts the aluminum alloy plate body into four triangular sections.

[0008] A further improvement is that the staggered reinforcing ribs divide the gap between adjacent square support plates into four triangular structures.

[0009] A further improvement is that a cylindrical reinforcing rod is fixedly connected at the connection between the reinforcing rib and the reinforcing bar.

[0010] A further improvement is that the main body of the aluminum alloy plate and its internal structure are both made of aluminum alloy material.

[0011] A further improvement is that the surface of the aluminum alloy plate is coated with a polyimide ceramic coating and an aluminum-based ceramic coating from the inside out.

[0012] By employing the above technical solution, this utility model provides an aluminum alloy plate with strong tensile strength, which has at least the following beneficial effects: 1. This utility model uses a square support plate and ribs to form a multi-cavity irregular structure, which improves the bending and torsional strength of the aluminum alloy plate body. The cross-connected reinforcing ribs further improve the overall strength. The aluminum alloy plate is divided into four triangular sections by X-shaped reinforcing beams, which can effectively restrain the internal deformation of the aluminum alloy plate under stress, avoid the overall strength reduction caused by local instability of the frame, and distribute stress more evenly. Moreover, the aluminum alloy plate is mostly hollow inside, which is lighter and has stronger tensile strength compared to solid aluminum alloy plates.

[0013] 2. This utility model uses a regular hexagonal through-hole with multiple rigid support edges formed by the hole walls. When under tension, the stress can be distributed through multiple edges, making it less prone to local indentation or instability. It can stably bear and transmit tensile force, further improving the fracture resistance of the aluminum alloy plate body. The X-shaped structure composed of square support plates and ribs forms multiple trapezoidal structures inside the aluminum alloy plate body. When the aluminum alloy plate body is subjected to lateral or longitudinal loads, its oblique edges decompose and transmit part of the load, further improving the overall tensile strength of the aluminum alloy plate body.

[0014] 3. This utility model increases the stress-bearing area of ​​the connection point by using a cylindrical reinforcing rod. When external force is transmitted to the connection point, the larger stress-bearing area allows the stress to be distributed more evenly on the cylindrical reinforcing rod and the surrounding material, reducing local stress peaks and thus preventing tearing at the connection point due to stress concentration.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 The existing triangular support unit design in aluminum alloy plates lacks mechanical optimization and cannot effectively distribute stress, leading to localized deformation or fracture under high loads. This embodiment provides an aluminum alloy plate with strong tensile strength, optimizing the support unit. While maintaining a lightweight design, it improves the overall bending and torsional strength of the aluminum alloy plate, resulting in more uniform stress distribution and stronger tensile strength. Please refer to... Figures 1-4The aluminum alloy plate with strong tensile strength includes an aluminum alloy plate body 1. Multiple square support plates 2 are arrayed inside the aluminum alloy plate body 1. Ribs 3, connected to the inner walls of both sides of the aluminum alloy plate body 1, are fixed to the four corners of each square support plate 2, forming a multi-cavity irregular structure with tensile and torsional resistance. A through hole 4 is opened through the center of each square support plate 2 to disperse stress. X-shaped reinforcing beams 5 are installed on the aluminum alloy plate body 1 to uniformly disperse stress. Reinforcing ribs 6, which increase strength, are interlaced between adjacent ribs 3. T-shaped connecting blocks 7 are installed on one side of the aluminum alloy plate body 1, and a concave connecting seat 8 adapted to the T-shaped connecting block 7 is installed on the other side. The aluminum alloy plate body 1 is constructed by the square support plates 2 and ribs 3. The aluminum alloy plate body 1 has a multi-cavity irregular structure inside, which improves the bending and torsional strength of the aluminum alloy plate body 1. The cross-connected reinforcing ribs 6 further improve the overall strength. The X-shaped reinforcing beams 5 enhance the overall buckling and torsional resistance of the aluminum alloy plate body 1 and transfer the stress on the aluminum alloy plate body 1 in multiple directions, so that the stress is evenly distributed throughout the entire aluminum alloy plate body 1. Moreover, the aluminum alloy plate body 1 is mostly hollow inside, which is lighter and has stronger tensile strength compared to solid aluminum alloy plates. The T-shaped connecting block 7 can be slid into the concave connecting seat 8 on the side of another aluminum alloy plate body 1 to quickly complete the splicing of multiple aluminum alloy plate bodies 1.

[0020] Specifically, the through hole 4 is a regular hexagonal structure, and the square support plate 2 and four ribs 3 form an X-shaped structure within the aluminum alloy plate body 1. The walls of the regular hexagonal through hole 4 form multiple rigid support edges, which can distribute stress through multiple edges when under tension, making it less prone to local indentation or instability. It can stably bear and transmit tensile force, further improving the fracture resistance of the aluminum alloy plate body 1. The X-shaped structure formed by the square support plate 2 and ribs 3 creates multiple trapezoidal structures inside the aluminum alloy plate body 1. When the aluminum alloy plate body 1 is subjected to lateral or longitudinal loads, its oblique edges decompose and transmit part of the load, further improving the overall tensile strength of the aluminum alloy plate body 1.

[0021] Specifically, the X-shaped reinforcing beam 5 cuts the aluminum alloy plate body 1 into four triangular sections; by dividing the aluminum alloy plate body 1 into four triangular sections, the internal deformation of the aluminum alloy plate body 1 under stress can be effectively constrained, avoiding the overall strength reduction of the frame due to local instability, and the stress is more evenly distributed.

[0022] Specifically, the staggered reinforcing ribs 6 divide the gap between adjacent square support plates 2 into four triangular structures; thereby filling the gap between adjacent square support plates 2, and through the separated triangular structures, improving the overall strength of the aluminum alloy plate body 1 and enhancing the overall anti-breakage performance of the aluminum alloy plate body 1.

[0023] Specifically, the main body 1 of the aluminum alloy plate and its internal structure are all made of aluminum alloy material; thereby avoiding the failure of the interface due to electrochemical corrosion of dissimilar metals, which would weaken the overall structure and reduce the tensile strength.

[0024] Furthermore, the surface of the aluminum alloy plate body 1 is coated with a polyimide ceramic coating 10 and an aluminum-based ceramic coating 11 from the inside out. The aluminum-based ceramic coating 11 forms a hard shell protective layer on the surface of the aluminum alloy plate body 1, preventing the aluminum plate surface from developing micro-cracks due to scratches and corrosion. The polyimide ceramic coating 10 has excellent corrosion resistance and UV aging resistance, preventing the aluminum plate surface from oxidizing or developing corrosion pits. Corrosion weakens the effective load-bearing area of ​​the substrate and reduces the tensile load-bearing capacity.

[0025] Example 2 Since the connection point between rib 3 and reinforcing rib 6 is a weak area in tensile strength, tensile force is prone to cause tearing due to "stress concentration" at this point. Therefore, based on Example 1, as... Figures 1-4 As shown, a cylindrical reinforcing rod 9 is fixedly connected to the connection between the reinforcing rib 6 and the reinforcing rib 3 in the device. The cylindrical reinforcing rod 9 increases the stress-bearing area of ​​the connection point. When external force is transmitted to the connection point, the larger stress-bearing area allows the stress to be distributed more evenly on the cylindrical reinforcing rod 9 and the surrounding material, reducing local stress peaks and thus preventing tearing at the connection point due to stress concentration.
