Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy sheet metal parts technology, and in particular to a pressure-resistant and wear-resistant aluminum alloy sheet metal part. Background Technology

[0002] Sheet metal work is a comprehensive cold processing technology for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming. Aluminum alloy sheet metal parts are widely used in construction, automotive, aerospace, and other fields due to their lightweight, high strength, and corrosion resistance.

[0003] In the prior art, a search revealed a Chinese patent disclosing "A Wear-Resistant Aluminum Alloy Sheet Metal Part," application number "202320002358.2." This patent mainly includes an aluminum alloy sheet metal part body; a first wear-resistant layer is fixedly installed on the inner side of the aluminum alloy sheet metal part body, a second wear-resistant layer is fixedly installed on the outer side of the aluminum alloy sheet metal part body, a reinforcing component is provided on the outer side of the aluminum alloy sheet metal part body, and a first mounting hole is opened on the inner side of the aluminum alloy sheet metal part body, with two sets of the first mounting hole, and a first protective component is provided on the inner side of the first mounting hole. Although the aforementioned wear-resistant aluminum alloy sheet metal part strengthens the wear resistance of the inner side of the aluminum alloy sheet metal part body through the first wear-resistant layer and improves the wear resistance of the outer side of the aluminum alloy sheet metal part body through the second wear-resistant layer, it effectively achieves wear resistance treatment for the aluminum alloy sheet metal part. However, when reinforcing sheet metal parts are reinforced with reinforcing ribs, the addition of these ribs requires fixing them to the sheet metal part, increasing both the manufacturing process and the weight of the sheet metal part. Furthermore, creating through holes inside the reinforcing ribs to achieve weight reduction further complicates the manufacturing process. Additionally, the rubber sleeves must first be fitted into the mounting holes before being secured with bolts. If the rubber sleeves need to be replaced after wear, the entire bolt assembly must be removed to extract the damaged rubber sleeve from the mounting holes, making the operation cumbersome. Therefore, this invention provides a pressure-resistant and wear-resistant aluminum alloy sheet metal part to solve the problems mentioned in the background section. Utility Model Content

[0005] To achieve the above objectives, a pressure-resistant and wear-resistant aluminum alloy sheet metal part is provided, including an aluminum alloy sheet metal part body and mounting holes provided inside the aluminum alloy sheet metal part body. The aluminum alloy sheet metal part body is configured as an L-shaped structure with a bending portion.

The purpose of the drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-3 This utility model discloses a pressure-resistant and wear-resistant aluminum alloy sheet metal part, comprising an aluminum alloy sheet metal body 1 and mounting holes 6 disposed inside the aluminum alloy sheet metal body 1. The aluminum alloy sheet metal body 1 is configured as an L-shaped structure with a bent portion 2, and the bent portion 2 is configured with rounded corners to reduce stress concentration and improve the overall compressive strength of the structure. Multiple protruding ribs 4 are formed on the side of the bent portion 2 closest to the interior of the aluminum alloy sheet metal body 1, enhancing the support strength of the bent portion 2. A recessed portion 3 is formed on the side of the bent portion 2 opposite to the protruding ribs 4, creating an alternating convex-concave structure in the bent portion 2, which helps to disperse stress. The protruding ribs 4 and recessed portions 3 can be formed by stamping the aluminum alloy sheet metal body 1, which is simple and low-cost.

[0024] To further improve the surface wear resistance of the aluminum alloy sheet metal body 1, multiple grooves 5 are uniformly formed on the surface of the aluminum alloy sheet metal body 1. Each groove 5 has a micro-pit structure, which effectively reduces the contact area and lowers the coefficient of friction, thereby reducing wear. Simultaneously, the grooves 5 can also store lubricating oil or lubricant, forming a lubricating film to further reduce wear and friction. Furthermore, the grooves 5 can be formed by stamping the aluminum alloy sheet metal body 1, simplifying the processing.

[0025] Each aluminum alloy sheet metal body 1 has a flexible protective element 7 on its surface, near the mounting hole 6. The protective element 7 is a rubber pad, which has good elasticity and protection, preventing wear on the aluminum alloy sheet metal body 1 during external bolt installation. Installation is simple; the protective element 7 is simply fitted over the outside of the bolt when the external bolt is inserted into the mounting hole 6. Each protective element 7 has a through hole inside, and each end of the protective element 7 has a notch 8, which facilitates removal of the protective element 7 from the external bolt, making subsequent maintenance and replacement convenient.

[0026] To improve the wear resistance and corrosion resistance of the aluminum alloy sheet metal body 1, a wear-resistant layer 9 is provided on the outer side of the aluminum alloy sheet metal body 1. The wear-resistant layer 9 is made of hard alloy or ceramic material. The wear-resistant layer 9 gives the aluminum alloy sheet metal body 1 high hardness and high wear resistance, effectively resisting external wear. A corrosion-resistant layer 10 is provided on the outer side of the wear-resistant layer 9. The corrosion-resistant layer 10 is made of alumina or zinc plating. The corrosion-resistant layer 10 gives the aluminum alloy sheet metal body 1 good corrosion resistance, better protecting the aluminum alloy sheet metal body 1.

[0027] Working principle: By designing the bend 2 as a rounded corner structure, stress concentration can be reduced, improving the overall compressive strength of the structure. Simultaneously, the formed convex rib 4 enhances the supporting strength of the bend 2, and the recessed portion 3 creates an alternating convex-concave structure in the bend 2, which helps to disperse stress. Furthermore, the convex rib 4 and the recessed portion 3 can be manufactured by stamping the aluminum alloy sheet metal body 1, making manufacturing simple and low-cost.

[0028] The groove 5 on the surface of the aluminum alloy sheet metal body 1 can effectively reduce the contact area and lower the coefficient of friction, thereby reducing wear and further improving the surface wear resistance of the aluminum alloy sheet metal body 1. At the same time, the groove 5 can also be used to store lubricating oil or lubricant, forming a lubricating film, further reducing wear and friction. Moreover, the groove 5 can be made by stamping the aluminum alloy sheet metal body 1, which simplifies the processing.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
