Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum alloy processing technology, and in particular to an anodizing equipment for aluminum alloy profiles. Background Technology
[0002] Anodizing of aluminum alloys refers to the process in which aluminum alloy profiles are placed in an electrolyte as the anode material, and a cathode material is placed in the electrolyte. Under the action of an applied current, an oxide film is formed on the anode of the aluminum product. Anodizing is mainly used to overcome the defects of aluminum alloy surface hardness and wear resistance, expand the application range, and extend the service life.
[0003] In existing technologies, most anodizing electrolytic cells are open-top. However, bubbles are generated during anodizing, which leads to an increase in the gas pressure inside the electrolyte, causing the electrolyte to splash everywhere. Since dilute sulfuric acid is commonly used as the electrolyte in anodizing, it can cause corrosive damage to workers if splashed onto them. Therefore, existing anodizing electrolytic cells pose safety hazards when in use.
[0004] Therefore, we propose an anodizing equipment for aluminum alloy profiles to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an anodizing equipment for aluminum alloy profiles to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An anodizing device for aluminum alloy profiles includes an oxidation tank and a cathode plate installed in the oxidation tank. A pair of sliding cover plates are symmetrically installed on both sides of the upper port of the oxidation tank. The sliding cover plate is composed of a fixed plate, a connecting plate and a movable plate that are slidably sleeved on each other. The fixed plate is fixed to the outer edge of the oxidation tank. The upper surfaces of the fixed plate and the connecting plate are provided with guide grooves, and the lower surfaces of the connecting plate and the movable plate are respectively provided with guide blocks corresponding to the positions of the guide grooves.
[0008] The two ends of the pair of sliding covers are symmetrically provided with a power structure to drive the sliding covers to open or close. Each power structure includes a pair of brackets, which are respectively connected to the movable plates of the two sliding covers. Each bracket has a screw block fixed under it. The screw block is threaded through and connected to the same double-headed screw rod. The two screw blocks on the same double-headed screw rod have opposite spiral directions.
[0009] In a further embodiment, the same end of the double-headed screws of the two power structures is connected to a worm gear, and a worm is meshed under each worm gear. The two worms are coaxially connected by a connecting rod, and the end of one of the worms is connected to a motor.
[0010] In a further embodiment, the guide block is a rotatably mounted roller that rolls along a guide groove.
[0011] In a further embodiment, the vertical distance between the fixed plate and the connecting plate is 1-2 mm, and the vertical distance between the connecting plate and the movable plate is 1-2 mm.
[0012] In a further embodiment, both ends of the connecting plate and the movable plate are vertically connected to a cover edge, and the lower end face of the cover edge is not higher than the upper end face of the oxidation tank.
[0013] In a further embodiment, both edges of the two adjacent end faces of the two movable plates are provided with raised edges, and an observation groove is formed between the raised edges.
[0014] In a further embodiment, the lower surfaces of the fixed plate, connecting plate, and movable plate are all provided with an anti-corrosion layer.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention features a pair of sliding cover plates on an oxidation tank. These cover plates cover the upper port of the oxidation tank during the reaction, preventing electrolyte from splashing out and ensuring operational safety. The cover plates can also slide open to the sides, exposing a large working space above the oxidation tank, facilitating the placement or removal of aluminum alloy products. Furthermore, the cover plates employ a multi-level sliding plate structure, allowing them to be folded together when open, without occupying space on either side of the oxidation tank.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] 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.
[0025] Please see Figure 1-4 An anodizing device for aluminum alloy profiles includes an oxidation tank 1 and a cathode plate 2 installed in the oxidation tank 1. A pair of sliding cover plates are symmetrically installed on the two long sides of the upper port of the oxidation tank 1. Each sliding cover plate consists of a fixed plate 3, a connecting plate 4, and a movable plate 5 that are slidably connected to each other. The fixed plate 3 is fixed to the outer edge of the oxidation tank 1, while the connecting plate 4 is slidably connected to the fixed plate 3, and the movable plate 5 is slidably connected to the connecting plate 4. Guide grooves 13 are formed on the upper surfaces of both the fixed plate 3 and the connecting plate 4, with the guide grooves 13 extending along their length... The sliding direction of the connecting plate 4 and the movable plate 5 is consistent, and the lower surface of the connecting plate 4 is provided with a guide block 14 corresponding to the guide groove 13 on the upper surface of the fixed plate 3. The lower surface of the movable plate 5 is also provided with a guide block 14 corresponding to the guide groove 13 on the upper surface of the connecting plate 4. This allows the movable plate 5 to drive the guide block 14 to move in the guide groove 13 on the upper surface of the connecting plate 4. When the guide block 14 approaches the two ends of the guide groove 13 on the upper surface of the connecting plate 4, it can drive the connecting plate 4 to move, and the connecting plate 4 drives the guide block 14 to move in the guide groove 13 on the upper surface of the fixed plate 3.
[0026] Specifically, the guide block 14 is a rotatably mounted roller 141, and the roller 141 rolls along the guide groove 13. At the same time, the vertical distance between the fixed plate 3 and the connecting plate 4 is 1-2mm, and the vertical distance between the connecting plate 4 and the movable plate 5 is 1-2mm, so as to reduce the frictional resistance of the connecting plate 4 and the movable plate 5 when sliding.
[0027] Both ends of the connecting plate 4 and the movable plate 5 are vertically connected to the cover edge 15, and the lower end face of the cover edge 15 is not higher than the upper end face of the oxidation tank 1, so that the electrolyte is not easy to splash out from the gap between the short side of the connecting plate 4 and the movable plate 5 and the oxidation tank 1.
[0028] Both edges of the two movable plates 5 that are close to each other are provided with protruding edges 51. When the two movable plates 5 are tightly closed, a rectangular observation groove is formed between the protruding edges 51, which makes it convenient for staff to observe the reaction status.
[0029] The lower surfaces of the fixed plate 3, connecting plate 4 and movable plate 5 are all provided with an anti-corrosion layer 16. The anti-corrosion layer 16 can be made of, but is not limited to, polyurethane anti-corrosion coating, KNM22 acid-resistant paint, etc., to improve its acid resistance and help extend the service life of the sliding cover.
[0030] To facilitate quick opening and closing of the sliding cover, a power structure is symmetrically provided at the two short ends of the sliding cover to drive it to open or close. Each power structure includes a pair of brackets 6, which are respectively connected to the movable plates 5 of the two sliding covers. Each bracket 6 has a screw block 7 fixed underneath it. The screw block 7 is threaded through and connected to the same double-ended screw 8. The two screw blocks 7 on the same double-ended screw 8 have opposite spiral directions. The double-ended screw 8 is installed on the two short sides of the oxidation tank 1 through bearing seats. When the double-ended screw 8 rotates, the two screw blocks 7 move closer or further away from each other, and the two movable plates 5 move closer to each other to close the upper port of the oxidation tank 1. Conversely, when the two movable plates 5 move further away from each other, the upper port of the oxidation tank 1 can be opened.
[0031] Furthermore, to ensure that the two sets of power structures can work synchronously, a worm gear 9 is connected to the same end of the double-headed screw 8 of the two sets of power structures, and a worm 10 is meshed with the worm gear 9. The two worms 10 are coaxially connected by a connecting rod 11, and the end of one of the worms 10 is connected to a motor 12. The worm 10 and the connecting rod 11 are installed on one of the long sides of the oxidation tank 1 through a bearing seat. The motor 12 is supported by a mounting plate fixed to the outer wall of the oxidation tank 1, so that the motor 12 drives the two worms 10 to rotate synchronously, thereby driving the two worm gears 9 to rotate synchronously.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
