[0002] In order to improve the corrosion resistance, hardness, wear resistance and other properties of aluminum alloy products, aluminum alloy products need to be anodized before leaving the factory.

[0003] The existing anodizing racks do not have flaring on their teeth, so that acid substances are easily accumulated in the grooves of the teeth. The acid substances react chemically with the anodic electrophoretic paint of the product to generate sulfides, thereby affecting the yield of the product. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a hanging tooth and an anodic oxidation hanger to improve the yield rate of products.

[0009] The two elastic arms form an angle of 5° to 15°.

[0010] Furthermore, a notch is formed at one end of the elastic arm away from the connecting portion.

[0011] Furthermore, in the width direction of the elastic arm, the notch is centrally arranged.

[0012] Furthermore, in the width direction of the elastic arm, the ratio of the height of the notch to the width of the elastic arm is 0.4 to 0.6.

[0013] Furthermore, in the length direction of the elastic arm, the ratio of the length of the notch to the length of the elastic arm is 0.15 to 0.25.

[0014] Furthermore, the connecting portion and the tooth body are integrally formed.

[0015] Furthermore, a limiting groove is provided at one end of the elastic arm away from the connecting portion, and the limiting groove is located at a side of the elastic arm away from the drainage channel.

[0034] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0035] Please refer to Figure 1-Figure 5 Because aluminum alloy products are anodized by hanging the products on a hanger and then placing the hanger as a whole in a liquid tank for anodizing treatment, the existing hanger has structural design defects on the hanging teeth, which easily causes acid substances to accumulate in the grooves of the hanging teeth. These acid substances will react with the anode electrophoretic paint during the anodizing process to generate sulfides, and the generation of sulfides will affect the product yield.

[0036] Based on this, an anodizing hanger is provided, comprising a support 1, a suspension assembly 2 and a hanging tooth 3; the hanging tooth 3 comprises a connecting portion 31 and a U-shaped hanging tooth body 32; the hanging tooth body 32 has two symmetrically arranged elastic arms 321; a drainage channel 322 is formed between the two elastic arms 321, and the drainage channel 322 is distributed along the width w direction and the length direction of the elastic arm 321; an angle α of 5° to 15° is formed between the two elastic arms 321; a plurality of hanging teeth 3 are sequentially arranged in the length direction of the support 1, and the distribution direction of the drainage channel 322 of the hanging tooth 3 is perpendicular to the length direction of the support 1; the support 1 is connected to the suspension assembly 2. Specifically, the support 1 is welded to the suspension assembly 2. Optionally, the angle α is 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14° or 15°. Preferably, the hanging tooth 3 is welded to the support 1.

[0037] It can be understood that by providing two elastic arms 321, the tooth body 32 has a deformable property, so that the tooth body 32 can be tightly connected with the product, thereby improving the position stability of the product on the hanger; and a drainage channel 322 is formed between the two elastic arms 321, so that the tooth body 32 has no space for storing acid substances, thereby avoiding the generation of sulfides to the greatest extent and ensuring the product yield.

[0038] In some embodiments, a notch 3211 is formed at one end of the elastic arm 321 away from the connecting portion 31. The notch 3211 is formed to reduce the contact area between the elastic arm 321 and the product, thereby increasing the contact area between the product and the anodic electrophoretic liquid.

[0039] In some embodiments, the notch 3211 is centrally disposed in the width direction of the elastic arm 321 , so that the force arms formed on both sides of the notch 3211 in this direction remain consistent, thereby improving the position stability of the product on the hanging tooth 3 .

[0040] In some embodiments, in the width direction of the elastic arm 321, the ratio of the height h of the notch 3211 to the width w of the elastic arm 321 is 0.4-0.6, and optionally, the ratio is 0.4, 0.45, 0.5, 0.55 or 0.6. In the length direction of the elastic arm 321, the ratio of the length L of the notch 3211 to the length S of the elastic arm 321 is 0.15-0.25, and optionally, the ratio is 0.15, 0.16, 0.17, 0.18, 0.19, 0.2, 0.21, 0.22, 0.23, 0.24 or 0.25. The height and length of the notch 3211 are kept within the above ratio range, which can not only reduce the contact area between the product and the elastic arm 321, but also optimize the position stability of the product.

[0041] In some embodiments, the connecting portion 31 and the tooth body 32 are integrally formed, and in the width direction of the elastic arm 321, the length of the connecting portion 31 is equal to the width of the tooth body 32, thereby avoiding the formation of a space between the connecting portion 31 and the tooth body 32 where acid substances are easily accumulated, thereby ensuring the yield of the product.

[0042] In some embodiments, a limiting groove 3212 is provided at one end of the elastic arm 321 away from the connecting portion 31, and the limiting groove 3212 is located on the side of the elastic arm 321 away from the drainage channel 322. The setting of the limiting groove 3212 can make the outer sides of the two elastic arms 321 fit with the inner ribs of the product, thereby improving the stability of the product on the hanger. Specifically, the limiting groove 3212 is distributed along the width direction of the elastic arm 321, and the two ends are interconnected.

[0043] In some embodiments, the suspension assembly 2 includes a suspension plate 21 and a longitudinal beam 22; at least two longitudinal beams 22 are provided on one side of the suspension plate 21 in the thickness direction, and all the longitudinal beams 22 are evenly distributed in the length direction of the suspension plate 21; the support member 1 is connected to all the longitudinal beams 22. The suspension plate 21 is used to suspend the longitudinal beams 22, the support member 1 and the hanging teeth 3 in the liquid tank, and the longitudinal beams 22, the support member 1 and the hanging teeth 3 are immersed in the anodic electrophoresis liquid during the anodizing process, so that the product hung on the hanging teeth 3 is anodized.
