Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy preparation technology, specifically to an aluminum alloy composite anodizing surface treatment device. Background Technology

[0002] Aluminum alloys are metallic materials with aluminum as the base material and the addition of alloying elements such as copper, magnesium, and silicon. They combine lightweight, high strength, and corrosion resistance, and are widely used in aerospace, automotive manufacturing, architectural decoration, and 3C products. Composite anodizing involves immersing aluminum alloys in an electrolyte such as sulfuric acid, where an oxide film is formed on the surface through an electrolytic reaction. A porous base layer is first formed, followed by a hard layer or a coloring layer, and finally the pores are sealed. This process eliminates the need for spraying; instead, it allows the aluminum alloy surface to generate multiple layers through an electrochemical reaction. This improves wear resistance and corrosion resistance while also achieving coloring. The film layers are firmly bonded to the substrate, meeting the comprehensive performance requirements of materials in aerospace, automotive, and other fields.

[0003] Currently, during the anodizing of aluminum alloy composites, the heat generated by the electrolytic reaction easily raises the temperature of the electrolyte, dissolves the oxide film, and releases harmful gases such as acid mist, polluting the environment and affecting operational safety. Therefore, we propose an aluminum alloy composite anodizing surface treatment device. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum alloy composite anodizing surface treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aluminum alloy composite anodizing surface treatment device, comprising an oxidation chamber and a top cover, wherein a support plate is fixedly connected to both outer walls of the oxidation chamber, and a reciprocating cylinder is provided on both sides of the top of the support plate and fixedly connected to the edge of the top cover;

[0006] A compressor refrigeration device is installed on the lower end of one side of the outer wall of the oxidation chamber. The output end of the compressor refrigeration device is connected to a circulation pipe. An aluminum alloy support mesh frame is fixedly connected to the bottom end of the top cover. Insertion holes are opened through the edges of both sides of the aluminum alloy support mesh frame. An air pump is installed on the upper end of one side of the outer wall of the oxidation chamber. An exhaust pipe is connected to the input end of the air pump. A gas purifier connected to the exhaust pipe is fixedly connected to one side of the air pump. A base plate is fixedly connected to both sides of the bottom end of the oxidation chamber. Several insertion rods are fixedly connected to the top of the base plate.

[0007] Preferably, the circulation conduit is spirally arranged inside the side wall of the oxidation tank, and the circulation conduit extends to the upper end of the oxidation tank.

[0008] Preferably, a sealing ring is fixedly connected to the bottom edge of the top cover.

[0009] Preferably, the aluminum alloy support frame is U-shaped and has protruding blocks at both ends of the opening.

[0010] Preferably, each of the plurality of the insertion rods corresponds to a insertion hole, and the diameter of the insertion rod is larger than the diameter of the insertion hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by using a compressor refrigeration device and a spiral circulation duct, the heat generated during the oxidation process is removed in real time and the cold air is spread to the surface of the electrolyte, which avoids the electrolyte temperature from being too high and causing the oxide film to dissolve, thus ensuring the quality of the film layer; then, in conjunction with an air pump and a gas purifier, harmful gases such as acid mist and cold air volatilized during the oxidation process are extracted in real time through the exhaust pipe, and discharged after purification treatment, which effectively improves the working environment; and the U-shaped aluminum alloy bearing mesh frame simplifies the fixing and loading / unloading of workpieces through the interference fit of the insertion holes and insertion rods.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 The present invention provides the following technical solution:

[0020] Example 1: An aluminum alloy composite anodizing surface treatment device, including an oxidation chamber 1 and a top cover 2. Support plates 11 are fixedly connected to both outer walls of the oxidation chamber 1. Reciprocating cylinders 12 are fixedly connected to the edges of the top cover 2 on both sides of the top of the support plates 11. A sealing ring 21 is fixedly connected to the bottom edge of the top cover 2.

[0021] In use, first place the aluminum alloy workpiece in the oxidation chamber 1, then inject electrolyte to submerge the workpiece, start the reciprocating cylinder 12 on the support plate 11, and after the top cover 2 is sealed and attached to the oxidation chamber 1 through the sealing ring 21, it is energized. The aluminum alloy, as the anode, forms an oxide film in the electrolyte. After completion, the reciprocating cylinder 12 lifts the top cover 2 and the workpiece can be taken out.

[0022] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a compressor refrigeration device 13 is installed at the lower end of the outer wall of one side of the oxidation box 1, and a circulation conduit 14 is connected to the output end of the compressor refrigeration device 13; an aluminum alloy support mesh frame 22 is fixedly connected to the bottom end of the top cover 2, and insertion holes 201 are provided through the edges of both sides of the aluminum alloy support mesh frame 22; a vacuum pump 31 is installed at the upper end of the outer wall of one side of the oxidation box 1, and an exhaust pipe 3 is connected to the input end of the vacuum pump 31; a gas purifier 32 connected to the exhaust pipe 3 is fixedly connected to one side of the vacuum pump 31; a bottom plate 4 is fixedly connected to both sides of the bottom end of the oxidation box 1, and several insertion rods 41 are fixedly connected to the top of the bottom plate 4; the circulation conduit 14 is spirally arranged inside the side wall of the oxidation box 1, and the circulation conduit 14 extends to the upper end of the oxidation box 1; the aluminum alloy support mesh frame 22 is U-shaped and has protruding blocks at both ends of the opening; several insertion rods 41 correspond to the insertion holes 201, and the diameter of the insertion rods 41 is larger than the diameter of the insertion holes 201.

[0023] In use, the aluminum alloy workpiece is first placed into the U-shaped aluminum alloy support frame 22. As the aluminum alloy support frame 22 descends to the oxidation box 1, it is fixed to the bottom insertion rod 41 of the oxidation box 1 through the two side insertion holes 201. Then, the compressor refrigeration equipment 13 is started. The coolant flows spirally through the box wall through the circulation pipe 14 to control the temperature, and the cold gas spreads to the surface of the electrolyte to further cool the inside of the oxidation box 1, avoiding the generation of a large amount of heat during the oxidation process inside the oxidation box 1. At the same time, the air pump 31 draws the acid mist into the gas purifier 32 through the exhaust pipe 3 for treatment, avoiding the direct discharge of gas and pollution of the environment. When the oxidation is energized, the aluminum alloy forms an oxide film in the electrolyte. After the oxidation is completed, the reciprocating cylinder 12 raises the top cover 2 to perform static cooling of the aluminum alloy. After the cooling is completed, the aluminum alloy is taken out from the openings at both ends of the aluminum alloy support frame 22 for later use.
