Description

Technical Field

[0001] This application relates to the technical field of aluminum alloy oxidation processes, and in particular to an aluminum alloy cylinder tube anodizing device and oxidation process. Background Technology

[0002] Aluminum alloy cylinder tubes are cylindrical metal components used to guide the piston in linear reciprocating motion within the cylinder. In an engine cylinder, air expands, converting thermal energy into mechanical energy. In a compressor cylinder, the gas is compressed by the piston, increasing its original pressure. The housing of turbines, rotary piston engines, and similar devices is often referred to as a "cylinder." The manufacturing process of aluminum alloy cylinder tubes typically involves hard anodizing, achieving a surface hardness of approximately HV500 and an oxide film thickness of 25-250 micrometers, while also improving the product's insulation and wear resistance.

[0003] Currently, referring to Chinese patent document CN104032345A, an anodizing device and process for tubular aluminum alloy profiles are disclosed. This anodizing process achieves high-quality anodizing of the aluminum alloy profiles through steps such as degreasing water washing, alkaline etching water washing, neutralization and brightening water washing, anodizing water washing, sealing water washing, and drying. However, because water washing is involved in multiple steps, and the tubular aluminum alloy profiles are always installed inside the electrolytic cell during the water washing process, it is inconvenient to perform comprehensive water washing on the tubular aluminum alloy profiles and the inner wall of the electrolytic cell, thus affecting the efficiency of the entire anodizing process.

[0004] Aluminum alloy cylinder tubes are widely used, and the processing efficiency of the oxidation process directly affects the production cost of aluminum alloy cylinder tubes. Summary of the Invention

[0005] In order to improve the processing efficiency of the anodizing process for aluminum alloy cylinder tubes, this application provides an anodizing apparatus and process for aluminum alloy cylinder tubes.

[0006] In a first aspect, this application provides an aluminum alloy cylinder tube anodizing apparatus.

[0007] An anodizing apparatus for aluminum alloy cylinder tubes, comprising:

[0008] An electrolytic cell is provided with a cathode conductive device and an anode conductive device. Two sets of anode conductive devices are symmetrically arranged, and the two sets of anode conductive devices are used to install aluminum alloy cylinder tubes.

[0009] A lifting plate is vertically arranged, which can be raised and lowered above the electrolytic cell and inserted into the electrolytic cell. A water pipe is connected to the lifting plate. There are two lifting plates arranged opposite each other. Spray nozzles are arranged on the opposite side of the two lifting plates. The spray nozzles are connected to the water pipes. When the two lifting plates are inserted into the electrolytic cell, the anode conductive device is located between the two lifting plates.

[0010] A water tank is located above the two lifting plates. A support plate is fixed to the bottom of the water tank. The lifting plates are rotatably connected to the bottom of the support plate. A through hole communicating with the water tank is provided on the support plate. When the lifting plates rotate, the top of the water pipe can communicate with or be misaligned with the through hole.

[0011] The sealing component, when the water pipe is misaligned with the through hole, seals the top of the water pipe; when the water pipe is connected to the through hole, the sealing component opens the top of the water pipe.

[0012] The squeezing assembly is used to squeeze the water pipe when the water pipe is misaligned with the through hole, so that the residual water in the water pipe is squeezed out from the nozzle.

[0013] A rotating assembly, connected to the support plate, is used to drive the support plate to rotate; and

[0014] A support frame is mounted on the outside of the electrolytic cell, and a lifting assembly for driving the support plate to rise and fall is connected to the support frame.

[0015] By adopting the above technical solution, when it is necessary to clean the aluminum alloy cylinder tube in the electrolytic cell, the lifting assembly drives the support plate to descend, and the support plate drives the water tank and the lifting plate to descend, so that the lifting plate is inserted into the electrolytic cell, and the aluminum alloy cylinder tube is located between the two lifting plates. Then, the water tank supplies water to the water pipe, so that clean water is sprayed out from the nozzle to clean the aluminum alloy cylinder tube.

[0016] After cleaning the aluminum alloy cylinder tube for a period of time with the water pipe and through-hole connected, the rotating assembly drives the lifting plate to rotate, causing the water pipe to misalign with the through-hole. At this time, the sealing component seals the top of the water pipe, and the squeezing component squeezes the water pipe, causing the residual water in the water pipe to be sprayed out from the nozzle. This allows the nozzle to continuously spray clean water as the lifting plate rotates, thus cleaning the aluminum alloy cylinder tube from all angles. Simultaneously, as the lifting plate rotates, the water flowing out of the through-hole impacts the outer surface of the nozzle, cleaning it and improving its cleanliness.

[0017] After cleaning, the rotating component drives the lifting plate to rotate to the initial position. At this time, the water pipe is connected to the through hole, the water outlet of the water tank is closed, and then the lifting component drives the support plate to rise, thereby causing the lifting plate to rise and reset.

[0018] The above technical solution, through the cooperation of the lifting plate, water pipe, nozzle, sealing component and extrusion assembly, achieves the effect of all-round cleaning of aluminum alloy cylinder tube and self-cleaning of the outer surface of the nozzle, which improves the cleaning effect and cleaning efficiency of each cleaning of aluminum alloy cylinder tube in the electrolytic cell, thereby improving the processing efficiency of the oxidation process of aluminum alloy cylinder tube.

[0019] Optionally, the closure is a one-way valve, which is used to guide the flow of water from the water tank to the water pipe in one direction.

[0020] By adopting the above technical solution, the one-way valve can be set up so that when the water pipe is connected to the through hole, the water tank can inject water into the water pipe through the through hole, and when the water pipe is misaligned with the through hole, the top of the water pipe can be sealed.

[0021] Optionally, multiple water pipes are arranged horizontally, and multiple nozzles are connected to each water pipe. Multiple through holes are provided and correspond one-to-one with each water pipe.

[0022] By adopting the above technical solution, the installation of multiple water pipes and multiple nozzles can improve the cleaning effect on aluminum alloy cylinder pipes.

[0023] Optionally, the support plate has multiple cleaning holes distributed in the gaps between the multiple through holes; when the water pipe is connected to the through hole, the lifting plate blocks the cleaning hole; when the water pipe is misaligned with the through hole, the cleaning hole drains water to clean the outer surface of the nozzle.

[0024] By adopting the above technical solution and setting the cleaning holes, the cleaning effect on the outer surface of the nozzle is improved.

[0025] Optionally, a clearance groove is provided on one side of the lifting plate, and the water pipe passes through the clearance groove. The part of the water pipe that passes through the clearance groove is a compression section, and the compression section is elastic.

[0026] The extrusion assembly includes an extrusion plate and an extrusion drive. The extrusion plate is slidably disposed in the relief groove, and the extrusion drive is fixed on the lifting plate. The extrusion drive is used to drive the extrusion plate to slide so as to extrude the extrusion segment between the extrusion plate and the inner wall of the relief groove.

[0027] By adopting the above technical solution, when the water pipe is misaligned with the through hole, the extrusion drive pushes the extrusion plate to move, and the extrusion plate extrudes the extrusion section of the water pipe, so that the water pipe can continue to spray the residual clean water in the water pipe from the nozzle after being extruded, thereby achieving the effect of continuous water output from the nozzle as the lifting plate rotates, and improving the cleaning effect of aluminum alloy cylinder pipe.

[0028] Optionally, a rotating shaft is rotatably connected to the support plate. The rotating shaft is vertically arranged and fixedly connected to the lifting plate, and the rotating shaft passes through the clearance groove.

[0029] By adopting the above technical solution, the strength of the lifting plate is relatively low after the relief groove is opened, and the rotating shaft passes through the relief groove, which improves the strength of the lifting plate.

[0030] Optionally, the rotating assembly includes a drive motor and a gearbox, wherein the input shaft of the gearbox is coaxially fixed with the output shaft of the drive motor, and the output shaft of the gearbox is coaxially fixed with the rotating shaft.

[0031] By adopting the above technical solution, when it is necessary to drive the lifting plate to rotate, the drive motor drives the rotating shaft to rotate through the gearbox, and the rotating shaft drives the lifting plate to rotate.

[0032] Optionally, the lifting assembly includes a lifting cylinder, which is fixed on the support frame, and the piston rod of the lifting cylinder is vertically arranged and fixedly connected to the support plate.

[0033] By adopting the above technical solution, the support plate can be stably raised and lowered using a lifting cylinder.

[0034] Secondly, this application provides an oxidation process using an aluminum alloy cylinder tube anodizing device.

[0051] In summary, this application includes at least one of the following beneficial technical effects:

[0064] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0065] In a first aspect, embodiments of this application disclose an anodizing apparatus for aluminum alloy cylinder tubes.

[0066] Reference Figure 1The aluminum alloy cylinder tube anodizing device includes an electrolytic cell 1. The electrolytic cell 1 is equipped with a cathode conductive device 11 and an anode conductive device 12. Two sets of anode conductive devices 12 are symmetrically arranged and used to fix the aluminum alloy cylinder tube. A drain outlet 13 is provided at the bottom of the electrolytic cell 1.

[0067] Reference Figure 1 , Figure 2 Two lifting plates 2 are installed above the electrolytic cell 1, arranged vertically with a gap between them. Multiple vertical water pipes 21 are threaded through the lifting plates 2, arranged horizontally. Each water pipe 21 is connected to multiple nozzles 22, which protrude from the lifting plate 2 and are located on opposite sides of the two lifting plates 2.

[0068] In the process step requiring cleaning of the aluminum alloy cylinder tube, two lifting plates 2 are driven to descend, positioning the aluminum alloy cylinder tube between the two lifting plates 2, at which point the lifting plates 2 are inserted into the electrolytic cell 1. Then, water is sprayed onto the aluminum alloy cylinder tube using nozzles 22, and the lifting plates 2 can reciprocate within a certain angle. During the reciprocating motion of the lifting plates 2, the nozzles 22 continuously spray water, thus achieving comprehensive and efficient cleaning of the aluminum alloy cylinder tube. Because the aluminum alloy cylinder tube oxidation process involves multiple cleaning steps, this significantly improves the processing efficiency of the oxidation process.

[0069] Reference Figure 1 , Figure 3 In order to facilitate water supply to the water supply pipe 21, a water tank 3 is installed above the electrolytic cell 1, and a support plate 4 is fixed at the bottom of the water tank 3. Both lifting plates 2 are rotatably connected to the bottom of the support plate 4.

[0070] Reference Figure 3 , Figure 4 The support plate 4 has multiple through holes 41, and the bottom of the water tank 3 has multiple water outlets, which are connected to the through holes 41 one by one. The water outlets are automatically opened and closed by valves. When the lifting plate 2 is in the initial position, the water pipe 21 (refer to...) Figure 2 ) and are connected one-to-one with through hole 41.

[0071] Reference Figure 4 , Figure 5 When the lifting plate 2 rotates and the water pipe 21 is misaligned with the through hole 41, in order for the nozzle 22 to continue spraying clean water, the water pipe 21 has a squeezing section 211, which is elastic. A clearance groove 23 is provided on one side of the lifting plate 2, and the squeezing section 211 is located within the clearance groove 23. A squeezing assembly 5 (see reference) is connected to the lifting plate 2 for squeezing the squeezing section 211 on the water pipe 21. Figure 3 ).

[0072] Reference Figure 3The extrusion assembly 5 includes an extrusion plate 51 and an extrusion drive 52. The extrusion plate 51 is vertically oriented and slides horizontally within the relief groove 23. The extrusion drive 52 is an electric actuator, which is fixed to the lifting plate 2, and its piston rod end is fixedly connected to the extrusion plate 51. When it is necessary to extrude water from the water pipe 21, the electric actuator drives the extrusion plate 51 to slide, and the extrusion plate 51 extrudes the extrusion section 211 on the water pipe 21, thereby causing the extrusion section 211 to be pressed between the extrusion plate 51 and the inner wall of the relief groove 23.

[0073] Reference Figure 3 , Figure 5 A one-way valve is installed at the top of the water pipe 21. The one-way valve is used to enable one-way flow of water from the water tank 3 into the water pipe 21. Thus, when the water pipe 21 is squeezed, the water in the water pipe 21 can be sprayed out through the nozzle 22, achieving continuous water output from the nozzle 22.

[0074] Reference Figure 4 In addition, the support plate 4 has multiple cleaning holes 42, which are distributed in the gaps between the multiple through holes 41. When the water pipe 21 is connected to the through hole 41, the lifting plate 2 blocks the cleaning holes 42.

[0075] Reference Figure 6 For water pipe 21 (refer to) Figure 5 ) and through hole 41 (refer to Figure 4 A schematic diagram of the state when connected.

[0076] Reference Figure 7 Water pipe 21 (refer to) Figure 5 The diagram shows the state when the water pipe 21 is misaligned with the through hole 41. When the lifting plate 2 rotates to the point where the water pipe 21 is misaligned with the through hole 41, the cleaning hole 42 and the through hole 41 spray water onto the outer surface of the nozzle 22, thereby achieving the effect of cleaning the sewage splashed on the outer surface of the nozzle 22.

[0077] Reference Figure 3 A rotating assembly 6 for driving the lifting plate 2 is provided on the support plate 4. The rotating assembly 6 includes a drive motor 61 and a gearbox 62, both of which are fixed to the support plate 4. The input shaft of the gearbox 62 is coaxially fixed with the output shaft of the drive motor 61.

[0078] Reference Figure 3 , Figure 5 A rotating shaft 43 is rotatably connected to the support plate 4, and the bottom end of the rotating shaft 43 is inserted into and fixedly connected to the lifting plate 2. The output shaft of the gearbox 62 is coaxially fixed with the rotating shaft 43. In addition, in order to improve the strength of the lifting plate 2 at the relief groove 23, the rotating shaft 43 passes through the relief groove 23.

[0079] Reference Figure 1In order to achieve the lifting of the support plate 4 and the lifting plate 2, a support frame 7 is set on the outside of the electrolytic cell 1. There are two sets of support frames 7, and each set of support frames 7 is connected to a lifting component. The lifting component includes a lifting cylinder 8. The piston rod of the lifting cylinder 8 is set vertically downward. The support plate 4 is fixedly connected to the piston rod of the two lifting cylinders 8.

[0080] The implementation principle of the aluminum alloy cylinder tube anodizing device in this application embodiment is as follows: when the aluminum alloy cylinder tube needs to be cleaned, the lifting cylinder 8 drives the support plate 4 to descend, and the support plate 4 drives the water tank 3 and the lifting plate 2 to descend, so that the lifting plate 2 is inserted into the electrolytic cell 1 until the aluminum alloy cylinder tube is located between the two lifting plates 2.

[0081] Next, the water tank 3 opens its outlet and supplies water to the water pipe 21 through the through hole 41. Clean water is then sprayed from the nozzle 22, thus cleaning the aluminum alloy cylinder tube. After cleaning for a period of time, the drive motor 61 drives the rotating shaft 43 to reciprocate within a certain angle via the gearbox 62. The rotating shaft 43 drives the lifting plate 2 to rotate, causing the water pipe 21 to disengage from the through hole 41. Simultaneously, the electric actuator drives the extrusion plate 51 to move. Due to the obstruction of the one-way valve, the water pipe 21 is extruded and water is discharged from the nozzle 22, thus achieving continuous water output from the nozzle 22 when the lifting plate 2 rotates, enabling comprehensive cleaning of the aluminum alloy cylinder tube.

[0082] During the reciprocating swing of the lifting plate 2, the cleaning hole 42 is exposed to clean the outer surface of the nozzle 22, thus achieving self-cleaning of the nozzle 22.

[0083] After cleaning, the lifting plate 2 returns to its initial state, connecting the water pipe 21 and the through hole 41, and stopping the water supply from the outlet of the water tank 3. Then, the lifting cylinder 8 drives the support plate 4 to rise and reset, thereby raising the lifting plate 2 above the electrolytic cell 1.

[0084] This improves the efficiency of cleaning the aluminum alloy cylinder tubes in electrolytic cell 1.

[0085] Secondly, embodiments of this application disclose an oxidation process using an aluminum alloy cylinder tube anodizing device.

[0095] S9. Cleaning: The aluminum alloy cylinder tube is cleaned using an aluminum alloy cylinder tube anodizing device, while the electrolytic cell 1 is cleaned manually at the same time.

[0097] S11. Cleaning: The aluminum alloy cylinder tube is cleaned using an aluminum alloy cylinder tube anodizing device, while the electrolytic cell 1 is cleaned manually at the same time.

[0098] S12, Sealing: Inject sealing liquid into electrolytic cell 1 and perform sealing process on aluminum alloy cylinder tube at 24℃-26℃;

[0099] S13. Cleaning and drying: The aluminum alloy cylinder tube is cleaned using an aluminum alloy cylinder tube anodizing device, while the electrolytic cell 1 is cleaned manually until the aluminum alloy cylinder tube is dry.

[0100] S14. Unloading: Remove the aluminum alloy cylinder tube from the electrolytic cell 1.

[0101] The implementation principle of an oxidation process using an aluminum alloy cylinder tube anodizing device in this application embodiment is as follows: loading → degreasing → cleaning → alkaline etching → cleaning → neutralization → cleaning → brightening → cleaning → anodizing → cleaning → sealing → cleaning and drying → unloading. Since the oxidation process involves multiple cleaning steps, the aluminum alloy cylinder tube anodizing device is used for cleaning in each step, thereby improving the overall processing efficiency of the aluminum alloy cylinder tube oxidation process.

[0102] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
