[0001] The utility model relates to the technical field of flanged aluminum materials, and specifically relates to a large-diameter flanged special-shaped aluminum material. Background Art

[0002] With the continuous development of industry, as one of the key sealing parts, the demand for flanged aluminum bushings has also increased. As an important industrial seal, flanged aluminum bushings are often used in mechanical equipment to seal components such as compressor cylinders and pistons; in automobile manufacturing, they are often used to seal bearings and shaft holes to prevent lubricating oil leakage; in addition, they are also used to seal various pipelines, valves and equipment to prevent medium leakage, and have a wide range of application scenarios.

[0003] In today's industrial environment with the continuous progress of industrial technology and the improvement of automation, the performance requirements for mechanical equipment and components are also getting higher and higher. In traditional flanged aluminum bushings, due to the smooth surface structure, it is difficult to retain oil on the smooth surface, and thus there are often phenomena such as oil dryness affecting sealing and accelerating wear, resulting in an increase in the failure rate of flanged aluminum bushings. Therefore, this application proposes a large-diameter flanged special-shaped aluminum material to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a large-diameter flanged special-shaped aluminum material, so that a certain amount of oil can be evenly retained on the surface of the bushing aluminum material, improving the sealing durability of the bushing aluminum material, enhancing the sealing effect while enhancing the durability and improving the overall service performance.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A large-diameter flanged special-shaped aluminum material, comprising: a liner tube, one end of the liner tube is provided with a flanging plate, the flanging plate and the liner tube are integrally formed, and the radius of the flanging plate is twice the radius of the liner tube; a first guide groove opened on the outer peripheral wall of the liner tube, and the first guide groove is distributed along the axial direction of the liner tube.

[0010] Preferably, a fourth arc chamfer is provided at the angle between the outer peripheral wall of the liner and the end face of the flanging plate, and the ratio of the connection length of the fourth arc chamfer with the outer peripheral wall of the liner to the connection length of the fourth arc chamfer with the end face of the flanging plate is 5:2.

[0011] Preferably, a first arc chamfer is provided at the outer peripheral edge of the end face of the liner away from the flanging plate, and a second arc chamfer is provided at the edge between the two end faces of the flanging plate and the circumferential surface of the flanging plate.

[0012] Preferably, third arc chamfers are provided at the edges of the first guide groove and the second guide groove and the outer peripheral surface of the liner.

The following describes each embodiment of the present utility model in detail with reference to the drawings.

[0025] Embodiment

[0026] Please refer to Figures 1 to 7 , the present utility model preferably provides the following technical solution:

[0027] A large-diameter flanged special-shaped aluminum material, comprising: a liner tube 1, one end of the liner tube 1 is provided with a flanging plate 2, the flanging plate 2 and the liner tube 1 are integrally formed, the radius of the flanging plate 2 is twice the radius of the liner tube 1, and the whole is a large-diameter flanged bushing aluminum material, having better sealing performance and structural strength.

[0028] In a further embodiment, a first guide groove 3 is formed on the outer peripheral wall of the liner tube 1, the first guide groove 3 is distributed along the axial direction of the liner tube 1, and multiple first guide grooves 3 are formed, and the multiple first guide grooves 3 are evenly distributed around the peripheral wall of the liner tube 1. A second guide groove 4 is formed on the outer peripheral wall of the liner tube 1, the second guide groove 4 is formed in a circle around the liner tube 1, and the second guide groove 4 communicates with the multiple first guide grooves 3. By forming multiple first guide grooves 3 on the outer peripheral wall of the liner tube 1 and the second guide groove 4 communicating with the multiple first guide grooves 3, during the assembly and application of the bushing aluminum material, a certain amount of oil can be retained on the outer peripheral wall of the liner tube 1, and the retained oil can be evenly dispersed on the outer peripheral wall of the liner tube 1 by the multiple first guide grooves 3 and the second guide groove 4. Compared with the surface of the traditional smooth bushing aluminum material, it not only improves the sealing durability and the sealing effect, but also reduces wear and is more durable.

[0029] In this embodiment, the first guide groove 3 penetrates through one end face of the liner 1 away from the flanging plate 2, and the second guide groove 4 is located at one end of the liner 1 close to the flanging plate 2. This structural design enables the hydraulic oil to be diverted by the second guide groove 4 when overflowing towards the flanging plate 2 end in the first guide groove 3, avoiding the overflow of the hydraulic oil on the surface of the liner 1. A fourth arc chamfer 8 is provided at the angle between the outer peripheral wall of the liner 1 and the end face of the flanging plate 2. The ratio of the connection length of the fourth arc chamfer 8 with the outer peripheral wall of the liner 1 to the connection length of the fourth arc chamfer 8 with the end face of the flanging plate 2 is 5:2. The fourth arc chamfer 8 with this proportional structure can better play a sealing effect and prevent the overflow of hydraulic oil when the bushing aluminum material is assembled and applied.

[0030] In a further embodiment, a first arc chamfer 5 is provided at the outer peripheral edge of one end face of the liner 1 away from the flanging plate 2, a second arc chamfer 6 is provided at the edge between the two end faces of the flanging plate 2 and the circumferential surface of the flanging plate 2, and a third arc chamfer 7 is provided at the edge of the first guide groove 3 and the second guide groove 4 with the outer peripheral surface of the liner 1, which can reduce the wear between the fittings. In addition, the setting of the third arc chamfer 7 is beneficial to the diffusion of the hydraulic oil in the first guide groove 3 and the second guide groove 4 towards the outer peripheral wall of the liner 1.

[0031] During use, through the design that the radius of the flanging plate 2 is twice the radius of the liner 1, the overall is a large outer diameter flanging bushing aluminum material, which has better sealing performance and structural strength. By providing multiple first guide grooves 3 on the outer peripheral wall of the liner 1 and second guide grooves 4 communicating with the multiple first guide grooves 3, during the assembly and application of the bushing aluminum material, a certain amount of hydraulic oil can be retained on the outer peripheral wall of the liner 1, and the retained hydraulic oil can be evenly dispersed on the outer peripheral wall of the liner 1 by the multiple first guide grooves 3 and the second guide grooves 4. Compared with the surface of the traditional smooth bushing aluminum material, it not only improves the sealing durability and enhances the sealing effect, but also reduces the wear and is more durable. Further, by providing an arc chamfer with a ratio of 5:2 at the angle between the outer peripheral wall of the liner 1 and the end face of the flanging plate 2, it can play a good sealing effect and prevent the overflow of hydraulic oil when the bushing aluminum material is assembled and applied. The overall performance is excellent and it has high practicality.
