Description

Technical Field

[0001] The utility model relates to the technical field of anodic oxidation, and more specifically to an auxiliary anode device for improving the coating uniformity. Background Art

[0002] As is well known, the anodic oxidation process is an electrochemical process for generating an oxide film on a substrate. Anodic oxidation improves corrosion resistance and wear resistance, enables various colors to have better adhesion on the metal surface, and has good decorative effects. Secondly, the most commonly used material for anodic oxidation is aluminum alloy, which is the most widely used type of non-ferrous metal structural material in industry.

[0003] The specific steps of the anodic oxidation process are as follows: First, the aluminum material is degreased and pickled to remove the naturally formed oxide film on the surface, and then it is placed in a tank filled with dilute sulfuric acid solution. After electrification, a new oxide film will be formed on the surface of the aluminum substrate at the anode. The generated oxide film is thicker and stronger than the natural oxide coating of aluminum. Then, the aluminum material is taken out, cleaned, and placed in a prepared dye bath for dyeing.

[0004] Before the aluminum material is immersed in the dye bath, after the bracket fixes the parts, the two are then placed in the dye bath. At this time, the position where the parts contact the bracket is fixed during the immersion and dyeing process, and the contact position between the bracket and the parts cannot be adjusted, resulting in the contact area affecting the oxidation effect and bringing certain deficiencies to the anodic oxidation process of aluminum materials. Summary of the Utility Model

[0005] In view of the above problems existing in the prior art, one aspect of the purpose of the present utility model is to provide an auxiliary anode device for improving the coating uniformity to solve the above deficiencies of the prior art.

[0006] To achieve the above purpose, the present utility model provides an auxiliary anode device for improving the coating uniformity, which includes a dyeing barrel and an aluminum part, and further includes: a bracket detachably arranged on the dyeing barrel, a lever is arranged on the bracket through an elastic reset member, a plurality of cross bars are arranged on the lever, and each cross bar is used for carrying the aluminum part; a carrying plate matched with the aluminum part is arranged on the dyeing barrel.

[0007] Preferably, a plurality of limiting grooves are circumferentially formed on the dyeing barrel, and each limiting groove is a rectangular structure.

[0008] Preferably, the bracket is provided with protruding parts that are snap-fitted with the respective limiting grooves.

[0009] Preferably, each protruding part is a rectangular structure.

[0010] Preferably, a through groove is formed on the carrying plate, and the through groove is a circular structure.

[0011] Preferably, the aluminum part is specifically composed of a cylinder and an outer sleeve connected to the cylinder, and the diameter of the cylinder is smaller than the diameter of the through groove.

[0012] Preferably, the outer set cooperates with the mounting plate.

[0013] Preferably, the bracket is further provided with a first positioning portion, and the lever is provided with a second positioning portion cooperating with the first positioning portion.

[0014] In the above technical scheme, the utility model provides an auxiliary anode device for improving the uniformity of coating, which has the following beneficial effects: before dyeing, the lever is passed through the aluminum part and connected to multiple cross bars, and the aluminum part is carried by the cooperation of the two. After the aluminum part is immersed in the dyeing barrel for a certain period of time, when it is necessary to adjust the contact position between the bracket and the aluminum part, the lever is first pressed downward to link the aluminum part to descend in the dyeing barrel. During the descent, the elastic reset part is compressed, and the aluminum part will be connected to the carrying plate and located on the top thereof. At this time, the lever continues to descend to separate the cross bar from the aluminum part. After separation, the lever is rotated to adjust the position of the cross bar and the aluminum part. Figures 5 to 6 The state is shown, and then the aluminum part is reset under the elastic force of the elastic reset part to support it again. At this time, the position of the supporting aluminum part has changed, which improves the oxidation effect and weakens or even avoids the contact position between the part and the bracket. During the immersion and dyeing process, the contact position between the bracket and the part cannot be adjusted, resulting in the contact place affecting the oxidation effect.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please refer to Figures 1-6 , an auxiliary anode device for improving the coating uniformity, which is used to solve the problem that before the aluminum material is immersed in the dyeing pool, after the bracket fixes the parts and then the two are put into the dyeing pool, the contact position between the parts and the bracket is fixed during the immersion dyeing process, and the contact position between the bracket and the parts cannot be adjusted, resulting in the contact area affecting the oxidation effect and bringing certain deficiencies to the aluminum anodizing process.

[0026] As a further technical solution proposed by the present utility model, it includes a dyeing barrel 1 and an aluminum part 4, and further includes: a bracket 2, which is detachably arranged on the dyeing barrel 1, a lever 3 is arranged on the bracket 2 through an elastic resetting part 5, a plurality of cross bars 3.2 are arranged on the lever 3, and each cross bar 3.2 is used to carry the aluminum part 4; a loading plate 1.2 matching with the aluminum part 4 is arranged on the dyeing barrel 1. Specifically, three cross bars 3.2 form a group, and they can be clamped or threadedly connected to the lever 3. Preferably, the plurality of cross bars 3.2 are threadedly connected to the lever 3. Before dyeing, the lever 3 is passed through the aluminum part 4 and threadedly connected to the plurality of cross bars 3.2, and the aluminum part 4 is carried through their cooperation. After the aluminum part 4 is immersed in the dyeing barrel 1 for a certain time, when it is necessary to adjust the contact position between the bracket and the aluminum part 4, first press the lever 3 downward to make it drive the aluminum part 4 to descend in the dyeing barrel 1. During the descent, the elastic resetting part 5 is compressed, and the aluminum part 4 will contact and be located on the top of the loading plate 1.2. At this time, when the lever 3 continues to descend, the cross bar 3.2 is separated from the aluminum part 4. After separation, the lever 3 is rotated to adjust and change the original corresponding position between the cross bar 3.2 and the aluminum part 4, such as Figures 5 to 6As shown in the state, it is then reset under the elastic force of the elastic reset member 5 to support the aluminum part 4 again. At this time, the position of supporting the aluminum part 4 has changed, improving the oxidation effect and weakening or even avoiding the problem that the position where the part contacts the bracket is fixed during the immersion dyeing process, and the position where the bracket contacts the part cannot be adjusted, resulting in the contact area affecting the oxidation effect.

[0027] In this embodiment, the elastic reset member 5 is specifically a spring, which is sleeved between the lever 3 and the bracket 2, as Figure 4 shown in the state. The elastic reset member 5 is used to reset when the applied force is released after pressing down the lever 3.

[0028] In another embodiment of the present invention, a plurality of limiting grooves 1.1 are circumferentially formed on the upper edge of the dyeing barrel 1. Each limiting groove 1.1 is specifically a rectangular structure. A protruding portion 2.1 that is engaged with each limiting groove 1.1 is provided on the bracket 2. Further, as Figure 2 and Figure 3 shown in the state, the number of the limiting grooves 1.1 is specifically three. By engaging the plurality of limiting grooves 1.1 with the protruding portions 2.1, the stability of the lever 3 when carrying the aluminum part 4 immersed in the dyeing barrel 1 is improved.

[0029] In still another embodiment of the present invention, the protruding portion 2.1 can be a circular or rectangular structure. Preferably, each protruding portion 2.1 is specifically a rectangular structure, as Figure 3 shown in the state. The rectangular protruding portion 2.1 is adapted to the limiting groove 1.1.

[0030] In still another embodiment of the present invention, a through groove 1.3 is formed on the carrier plate 1.2. The through groove 1.3 is specifically a circular structure, as Figure 5 shown in the state. The through groove 1.3 is used to pass through the cylindrical part of the aluminum part 4, so that the lever 3 can descend to give the rotating adjustment space for the cross bar 3.2, as Figures 5 to 6 shown in the state.

[0031] In still another embodiment of the present invention, preferably, the aluminum part 4 is specifically composed of a cylinder and an outer sleeve connected to the cylinder. The diameter of the cylinder is smaller than the diameter of the through groove 1.3. Further, as Figure 5 and Figure 6 shown in the state, the cylindrical structure part of the aluminum part 4 can pass through the opening of the through groove 1.3.

[0032] In another embodiment of the present utility model, preferably, the outer sleeve is matched with the carrying plate 1.2. Further, during the downward movement of the lever 3, the aluminum part 4 carried on the cross bar 3.2 will gradually contact the carrying plate 1.2, and during the subsequent downward stroke of the lever 3, the aluminum part 4 will stay on the carrying plate 1.2. At this point, the cross bar 3.2 after continuing to descend is separated from the aluminum part 4, and the contact position can be adjusted by rotation.

[0033] In another embodiment of the present utility model, a first positioning portion 2.2 is further provided on the bracket 2, and a second positioning portion 3.1 is provided on the lever 3 and is matched with the first positioning portion 2.2. Further, as Figure 2 shown in the state, through the cooperation of the first positioning portion 2.2 and the second positioning portion 3.1, after the lever 3 rotates, when the positions of the two do not correspond, that is, the cross bar 3.2 on the lever 3 changes the original contact position with the aluminum part 4, as Figures 2 to 3 shown in the state.

[0034] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
