Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, and more specifically, to a bending-resistant aluminum profile. Background Technology

[0002] As a core material of modern industry, aluminum profiles are widely used in construction, transportation, machinery and other fields due to their excellent performance. Aluminum profiles have high strength and corrosion resistance. Their density is only 1 / 3 of that of steel, but after alloying, their strength can reach more than 300MPa. Furthermore, a natural oxide film forms a protective layer, and after anodizing, the corrosion resistance is improved by 5-10 times. By giving aluminum profiles the ability to resist bending, they can play a corresponding role in load-bearing structures, supporting frames and other scenarios.

[0003] Traditional aluminum profiles are mostly cylindrical. This type of profile is easy to process and has low production cost, so it is widely used. However, due to the simple structure of cylindrical aluminum profiles, their bending resistance is generally poor. Especially when used in load-bearing frames, stress concentration occurs and cannot be distributed, which makes them prone to bending. Utility Model Content

[0004] The purpose of this invention is to provide a bending-resistant aluminum profile to solve the problems mentioned in the background art.

[0005] The simple structure of straight-tube aluminum profiles results in generally poor bending resistance, especially when used in load-bearing frames, leading to stress concentration and lack of dispersion, which in turn makes them prone to bending.

[0006] To achieve the above objectives, this utility model provides a bending-resistant aluminum profile, comprising an aluminum profile body with a rectangular cross-sectional shape. A rectangular hole is formed in the inner wall of the aluminum profile body at the middle. An auxiliary bending-resistant component is symmetrically arranged inside the rectangular hole in a top-to-bottom orientation. The auxiliary bending-resistant component includes horizontal reinforcing ribs symmetrically fixedly connected to the inner wall of the rectangular hole. The width of each of the two horizontal reinforcing ribs is the same as the inner diameter of the rectangular hole. Vertical reinforcing ribs are fixedly connected between the surface of each of the two horizontal reinforcing ribs and the inner wall of the rectangular hole. Several vertical reinforcing ribs are arranged at intervals.

[0007] By using horizontal and vertical reinforcing ribs, the overall rigidity of the aluminum profile is increased, the structural strength is improved, local deformation is reduced, and the aluminum profile is less prone to bending during use.

[0008] As a further improvement to this technical solution, the inner wall of the horizontal reinforcing rib is uniformly provided with a plurality of stress dispersion holes, the inner contour shape of the plurality of stress dispersion holes is a regular hexagon, and the inner wall of the plurality of vertical reinforcing ribs is provided with rectangular grooves, and a filling pad is inserted into the inside of the rectangular grooves, the filling pad being made of foam material.

[0009] By creating stress-dispersing holes and rectangular grooves, it is beneficial to distribute the load evenly, avoid excessive stress concentration, prevent local deformation, and reduce the overall weight, thus achieving lightweighting.

[0010] As a further improvement to this technical solution, weight reduction holes are provided on the inner walls of the aluminum profile body around all four sides. The inner contour shape of the four weight reduction holes is triangular. Two stress relief holes are symmetrically provided on the inner walls of both sides of the aluminum profile body. The inner contour shape of the multiple stress relief holes is regular hexagonal.

[0011] By setting multiple regular hexagonal stress relief holes, the load can be evenly distributed, stress concentration can be avoided, and the probability of local deformation of the aluminum profile body can be reduced.

[0012] As a further improvement to this technical solution, decorative grooves are symmetrically opened on the inner walls of both sides of the aluminum profile body, positioning grooves are symmetrically opened on the inner walls of the top and bottom of the aluminum profile body, and assembly plates are fixedly connected to the top and bottom of the aluminum profile body, with several fixing holes symmetrically opened on the inner walls of both sides of the two assembly plates.

[0013] By utilizing decorative grooves, the weight of the aluminum profile body is reduced, while also facilitating the use of tools to clamp the aluminum profile body for short-distance transportation and improving clamping stability.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this bending-resistant aluminum profile, by setting auxiliary bending-resistant components, horizontal and vertical reinforcing ribs are installed inside the rectangular holes by welding, which increases the overall rigidity of the aluminum profile body, improves the structural strength, reduces local deformation, and makes the aluminum profile body less prone to bending during use. At the same time, the aluminum profile body has a thinner wall thickness, which reduces the overall weight of the aluminum profile body. Combined with the horizontal and vertical reinforcing ribs, the stress is evenly distributed, achieving a balance between lightweight and high rigidity. Attached Figure Description

[0024] Example 1

[0025] Please see Figures 1-4As shown, this embodiment provides a bending-resistant aluminum profile, including an aluminum profile body 1. The cross-sectional shape of the aluminum profile body 1 is rectangular. Compared with the traditional straight cylindrical shape, it not only increases the moment of inertia but also enhances the bending resistance. A rectangular hole 2 is provided on the inner wall of the middle part of the aluminum profile body 1. Auxiliary bending-resistant components are symmetrically arranged inside the rectangular hole 2 in the upper and lower positions. The auxiliary bending-resistant components include horizontal reinforcing ribs 3 symmetrically fixedly connected to the inner sidewall of the rectangular hole 2. The width of the two horizontal reinforcing ribs 3 is the same as the inner diameter width of the rectangular hole 2. The surfaces of the two horizontal reinforcing ribs 3 are flush with the inner wall of the rectangular hole 2. Vertical reinforcing ribs 4 are fixedly connected between the inner walls of the rectangular holes 2. Several vertical reinforcing ribs 4 are spaced apart. By welding horizontal reinforcing ribs 3 and vertical reinforcing ribs 4 inside the rectangular holes 2, the overall rigidity of the aluminum profile body 1 is increased, the structural strength is improved, local deformation is reduced, and the aluminum profile body 1 is not easy to bend during use. At the same time, the aluminum profile body 1 has a thinner wall thickness, which reduces the overall weight of the aluminum profile body 1. With the help of horizontal reinforcing ribs 3 and vertical reinforcing ribs 4, the stress is evenly distributed, achieving a balance between lightweight and high rigidity.

[0026] The inner wall of the horizontal reinforcing rib plate 3 is uniformly provided with several stress dispersion holes 5. The inner contour of the stress dispersion holes 5 is a regular hexagon. By removing excess material, the weight of the horizontal reinforcing rib plate 3 is reduced, while the main load-bearing structure is retained. Furthermore, the regular hexagonal stress dispersion holes 5 are conducive to the uniform distribution of load, avoiding excessive stress concentration and local deformation. The inner wall of the vertical reinforcing rib plate 4 is provided with rectangular grooves 6. This reduces the weight of the vertical reinforcing rib plate 4, while retaining the main load-bearing structure and is conducive to the uniform distribution of load. A filling pad 7 is inserted into the rectangular groove 6. The filling pad 7 is made of foam material. By filling the rectangular groove 6 with foam material filling pad 7, it can achieve weight reduction and help absorb vibration and noise.

[0027] Weight-reducing holes 8 are formed on the inner walls of all four sides of the aluminum profile body 1. The inner contour of each of the four weight-reducing holes 8 is triangular. Utilizing the stability property of triangles, the four weight-reducing holes 8 can both reduce the weight of the aluminum profile body 1 and increase its rigidity, ensuring its stability. Two stress-relief holes 9 are symmetrically formed on the inner walls of both sides of the aluminum profile body 1. The inner contour of each stress-relief hole 9 is a regular hexagon. By setting multiple regular hexagonal stress-relief holes 9, the load can be evenly distributed, avoiding stress concentration and reducing the probability of local deformation of the aluminum profile body 1. Decorative grooves 10 are symmetrically formed on the inner walls of both sides of the aluminum profile body 1 to reduce the weight of the aluminum profile body 1. The weight of the body 1 is reduced, and it is convenient to use tools to clamp the aluminum profile body 1 for short-distance transportation, improving clamping stability. The top and bottom inner walls of the aluminum profile body 1 are symmetrically provided with positioning grooves 11. By observing the position of the positioning groove 11 at the end of the two aluminum profile bodies 1 that need to be connected, it is easy to assemble the two aluminum profile bodies 1. The top and bottom of the aluminum profile body 1 are fixedly connected with assembly plates 12. Several fixing holes 13 are symmetrically provided on the inner walls of both sides of the two assembly plates 12. The assembly plates 12 are used in conjunction with the positioning grooves 11 for positioning, so that the two aluminum profile bodies 1 can be accurately connected. At the same time, bolts are screwed into the fixing holes 13 to facilitate the fixing of the aluminum profile body 1 with other fixed objects.
