Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum alloy processing, specifically, it relates to a high-precision pickling treatment device for complex aluminum alloy cavities. Background Technology

[0002] Aluminum alloy parts are components made from aluminum as the base material, with the addition of other alloying elements (such as copper, silicon, magnesium, etc.), and belong to light metal materials. Wrought aluminum alloy parts are formed through processes such as extrusion and rolling, possessing good plasticity and machinability, and are commonly used in the manufacture of aerospace, automotive, and marine components. Cast aluminum alloy parts are produced using sand casting or metal mold casting processes, suitable for manufacturing complex-shaped parts. The surface of formed complex aluminum alloy parts requires pickling to remove surface oxide films, oil stains, and impurities, thereby improving subsequent processing performance and surface quality. Traditional pickling involves immersing the aluminum alloy in an acid-containing pickling tank, where the surface of the aluminum alloy reacts with the acid during the static process, resulting in low pickling efficiency. Application No.: CN202121221520.7 discloses an aluminum alloy forging pickling device. This device uses the meshing action of a rack to drive a rotating ring, thereby moving the pickling cylinder and the pickling acid solution within the cylinder, promoting the flow of the pickling acid solution on the aluminum alloy forging and accelerating the reaction efficiency. However, the entire cylinder rotates, resulting in relatively high energy consumption, and the function of this processing device is relatively limited.

[0003] In view of this, this utility model is proposed. Utility Model Content

A corresponding cleaning water ring 6 is provided, and a pipe support bracket 7 is provided below the cleaning water ring 6. Multiple flushing branch pipes 8 are provided on the inner wall of the cleaning water ring 6. A liquid storage tank 28 is provided below the first flushing cylinder 3, and a heating water tank 29 is provided below the second flushing cylinder 5. A temporary storage platform 11 is provided at one end of the main frame 1, and a temporary storage platform 22 is provided at the other end. A hot air blower 13 is provided on the outside of the temporary storage platform, and a drying hood 14 is provided at the air outlet of the hot air blower 13 for drying the aluminum alloy parts that have been pickled and cleaned.

[0026] The mobile power box 9 has a hollow structure. A transmission screw 26 is installed inside the mobile power box 9. An electric motor 19 is installed at the outer end of the mobile power box 9. A movable nut seat is provided on the transmission screw 26. The upper end of the movable nut seat is located above the upper plane of the mobile power box 9. The movable nut seat moves horizontally along the transmission screw 26.

[0027] A guide rod is arranged parallel to the side of the transmission screw 26. The guide rod passes through the movable nut seat. A movable slide groove 10 is opened on the top surface of the movable power box 9. The upper end of the movable nut seat is adapted to the movable slide groove 10. An auxiliary frame 17 is fixedly installed on the outside of the movable nut seat. The auxiliary frame 17 moves synchronously with the movable nut seat.

[0028] A lifting hydraulic cylinder 15 is fixedly installed on the top surface of the movable nut seat. A lifting top plate 16 is fixedly installed on the upper end of the telescopic rod of the lifting hydraulic cylinder 15. A lifting device 23 is installed on the bottom surface of the end of the lifting top plate 16. A placement basket 22 is hung on the lifting device 23 for placing the aluminum alloy parts to be processed.

[0029] The auxiliary platform 17 is equipped with a hydraulic tank 18, and an auxiliary support column is provided on the bottom surface of the auxiliary platform 17.

[0031] Both the liquid storage tank 28 and the heating water tank 29 are equipped with corresponding liquid supply pipes 21 for replenishing the cleaning liquid.

[0032] The working principle of this utility model is as follows: When pickling aluminum alloy parts, the aluminum alloy parts are placed in a placement basket 22. The placement basket 22 is hoisted onto a lifting top plate 16 by a lifting device 23. The lifting top plate 16 is adjusted by a lifting hydraulic cylinder 15. The hydraulic components such as the hydraulic pump, storage tank, and control valve of the lifting hydraulic cylinder 15 are located at the matching hydraulic box 18 to ensure the function of the lifting hydraulic cylinder 15. The motor 19 drives the transmission screw 26 to rotate, which in turn drives the moving nut seat and auxiliary platform 17 to move horizontally along the moving slide 10 to the degreasing cylinder 2. The lifting hydraulic cylinder 15 retracts, causing the placement basket 22 to sink into the degreasing cylinder 2. The degreasing cylinder 2 contains organic solvent or alkaline degreasing agent. The aluminum alloy parts are immersed in the degreasing solution for 5-15 minutes. During the degreasing soaking process, the stirrer 24 inside the degreasing cylinder 2 rotates, keeping the degreasing process in a liquid flow state and improving the degreasing efficiency.

[0033] After degreasing, the placement basket 22 is lifted from the degreasing cylinder 2 by the lifting hydraulic cylinder 15. The motor 19 drives the moving nut seat and the lifting hydraulic cylinder 15 to move horizontally to the corresponding position in the rinsing cylinder 3. The placement basket 22 is then lowered into the rinsing cylinder. The liquid pump 20 extracts clean water from the storage tank 28 and supplies it to the cleaning water ring 6, which is then sprayed out through the rinsing branch pipe 8 to rinse the degreased aluminum alloy parts. After degreasing and rinsing, the aluminum alloy parts are moved to the corresponding position in the pickling cylinder 4 and immersed in the pickling solution for pickling. The stirrer 24 in the pickling cylinder 4 is activated to keep the pickling solution agitated. The pickling solution can be nitric acid solution or hydrofluoric acid mixture. Nitric acid solution is typically used to treat the oxide film for 5-15 minutes, while hydrofluoric acid mixture is used for 3-8 minutes. The concentration and pH value of the pickling solution are tested and adjusted before pickling. The specific values ​​are not limited; after the pickling of the aluminum alloy solution, it is taken out and moved to the corresponding position of the rinsing cylinder 25. The heating water tank 29 is a water tank that can set the heating temperature according to the prior art. The temperature of the heating water tank 29 is set to 50-60℃. The pickled aluminum alloy is rinsed with warm water. After rinsing, the placement basket 22 is moved to the position of the temporary storage platform 22. The hot air blower 13 is a hot air blower that can set the hot air temperature according to the prior art. The hot air temperature is 50-70℃. The aluminum alloy parts are dried with high temperature gas. The pickled aluminum alloy parts are cleaned with heated water and then further dried with hot air. This can improve the drying efficiency and avoid the deformation or oxidation of the aluminum alloy parts caused by temperature difference. The electrical components in this application are all electrically connected. The working process of the electrical components can be manually controlled by a switch or controlled by a PLC system. No specific limitation is made.
