Description

Technical Field

[0001] This invention relates to the field of electroplating technology, and more particularly to an electroplating apparatus for producing nano-Invar alloy sheets. Background Technology

[0002] Nano-Invar alloys are an advanced variant of traditional Invar alloys, whose core properties are significantly enhanced through nanoscale microstructure control. By employing special melting, rolling, and heat treatment processes (such as rapid solidification and large plastic deformation), uniformly distributed nanocrystals or nanoscale precipitates are introduced into the alloy matrix, significantly improving the material's strength, hardness, and fatigue performance, while maintaining or even improving its low expansion characteristics, and enhancing dimensional stability and creep resistance.

[0003] During electroplating, nano-Invar alloys undergo intense plastic deformation to achieve an ultrafine-grained structure with a high grain boundary ratio and dislocation density, significantly enhancing the penetration effect of hydrogen atoms. However, the cathode hydrogen evolution side reaction is difficult to completely avoid during electroplating. Hydrogen atoms penetrating the substrate can easily cause delayed fracture or coating peeling, severely restricting product yield and service reliability. The continuous Joule heat input during electroplating leads to a continuous rise in the bath temperature, which exacerbates the hydrogen evolution reaction, increases the risk of hydrogen embrittlement, and alters the internal stress and microstructure of the coating. Simultaneously, cathode hydrogen evolution consumes hydrogen ions (acidic bath) or hydroxide ions (alkaline bath), causing the bath pH to continuously drift, deviating from the optimal process window and directly affecting the coating adhesion and uniformity. Traditional electroplating equipment relies heavily on overall bath circulation heat exchange and offline titration adjustment, resulting in slow response and limited control precision, making it difficult to meet the stringent requirements of nano-Invar alloys for micro-area environmental stability. Therefore, an electroplating device for producing nano-Invar alloy sheets is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an electroplating apparatus for producing nano-Invar alloy sheets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An electroplating apparatus for producing nano-Invar alloy sheets includes an electroplating tank and a control cabinet. An installation plate is provided on one side of the electroplating tank. The installation plate is connected to an electroplating frame assembly for electroplating nano-Invar alloy sheets via a lifting bracket. The electroplating frame assembly includes a double-sided adjusting plate and multiple U-shaped cooling tubes. A cooling seat is provided below the double-sided adjusting plate. Multiple pressurizing impellers for pressurizing the electroplating solution are provided on the cooling seat. An upper guide assembly is provided on the pressurizing impellers. The double-sided adjusting plate has multiple mounting slots, and multiple exchange holes are provided on the front and rear inner sidewalls of the mounting slots. A liquid storage tank is connected to the mounting slot through an adjusting pipe. Multiple adjusting holes corresponding to the exchange holes are provided on the front and rear inner sidewalls of the adjusting pipe. A liquid inlet perforated pipe is installed on the adjusting pipe at the adjusting hole. Both ends of the liquid inlet perforated pipe are connected to a unidirectional component for one-way delivery of acid and alkali liquids through a liquid guide pipe.

[0006] Preferably, the electroplating tank is assembled with the control cabinet via a mounting plate, the cooling seat is fixedly connected to the inner wall of the electroplating tank, and a heat exchange and cooling mechanism is provided at the bottom of the cooling seat.

[0007] Preferably, a lifting half-ring for mounting the lifting frame is fixed on the double-sided adjusting plate, and the internal cavity of the double-sided adjusting plate is connected to the U-shaped cooling pipes on both sides.

[0008] Preferably, the inner side of the U-shaped cooling tube at the bottom is rotatably connected to a plurality of disturbance wheels via a pin shaft. A guide shell is installed at the bottom of the double-sided adjustment plate. A hydraulic push rod is fixedly installed on the inner side wall of the guide shell. A drive rack is fixedly connected to the output end of the hydraulic push rod. A plurality of driven gears mesh on the drive rack. The driven gears are fixedly connected to the pin shaft.

[0009] Preferably, the upper guide assembly includes an upper guide tube fixed to the bottom of the double-sided adjustment plate, and a docking hollow magnetic seat is rotatably connected to the bottom of the upper guide tube. A auger conveying impeller is fixed on the docking hollow magnetic seat, and the auger conveying impeller is rotatably disposed inside the upper guide tube.

[0010] Preferably, the upper guide tube is connected to the U-shaped cooling tube through a double-sided adjustment plate, and the cooling seat is provided with multiple storage slots. The inner end face of the storage slot is rotatably connected to the booster impeller through a magnetic rotating shaft, and the top of the storage slot is fixedly connected with a docking ring that is compatible with the docking hollow magnetic seat.

[0011] Preferably, the top of the double-sided adjusting plate is fixedly connected to the liquid storage tank through a protective shell. The multiple liquid storage tanks are respectively filled with acidic solvent and alkaline solvent for adjusting the pH of the electroplating solution. The liquid storage tanks are rotatably connected to the adjusting tube through a steering seat.

[0012] Preferably, the one-way component includes a blocking ball that slides on the outer wall of the end of the liquid guide tube, the blocking ball having a flow hole, and the blocking ball being engaged with the adjustment hole of the adjustment tube.

[0013] Preferably, the two liquid guide tubes are connected by a compensating spring, the liquid guide tubes are slidably connected to the inner wall of the liquid inlet perforated tube, and a permeation plug is fixedly connected to the end of the liquid guide tube. The volume of the permeation plug is smaller than the internal cavity of the blocking ball.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This solution, through the setting of the upper guide component, can use the auger conveyor impeller to vertically lift the low-temperature liquid at the bottom to the upper guide tube and send it into the U-shaped cooling pipe, thereby realizing the directional transportation of the low-temperature liquid, enhancing the turnover rate of the tank liquid, and solving the vertical temperature stratification problem of "hot at the top and cold at the bottom" that is common in traditional electroplating tanks.

[0015] 2. By setting up a disturbance wheel, this solution can directly increase the turbulence of the electroplating solution near the workpiece surface through the synchronous rotation of the disturbance wheel. This not only quickly removes the Joule heat from the workpiece surface, but also reduces the thickness of the diffusion layer, which is beneficial to improving the limiting current density and the fineness of the coating crystallization.

[0016] 3. This solution, through the setting of a one-way component, allows the permeation plug to press against the blocking ball to form a seal when not in the working position; the acid-base adjustment solvent is only released when the exchange hole is reached, preventing leakage or accidental dripping of the acid-base adjustment agent during non-injection time, and preventing local overconcentration from causing corrosion damage to the nano-Invar alloy sheet. Utilizing the internal cavity of the blocking ball as a metering chamber, the amount of electroplating solution adjustment brought in with each rotation is fixed. This volumetric quantitative dosing is stable and unaffected by changes in liquid viscosity, ensuring the stability of pH adjustment. Attached Figure Description

[0022] Example, refer to Figures 1 to 12 An electroplating apparatus for producing nano-Invar alloy sheets includes an electroplating tank 1 and a control cabinet 2. An installation plate is provided on one side of the electroplating tank 1. The installation plate is connected to an electroplating frame assembly for electroplating nano-Invar alloy sheets via a lifting bracket 3. The electroplating frame assembly includes a double-sided adjustment plate 5 and multiple U-shaped cooling pipes 6. A cooling seat 7 is provided below the double-sided adjustment plate 5. Multiple pressurizing impellers 9 for pressurizing the electroplating solution are provided on the cooling seat 7. An upper guide assembly is provided on the pressurizing impellers 9. Furthermore, the electroplating tank 1 is assembled with the control cabinet 2 via a mounting plate. The cooling seat 7 is fixedly connected to the inner wall of the electroplating tank 1. A heat exchange and cooling mechanism is provided at the bottom of the cooling seat 7. A lifting semi-ring 4 for hanging the lifting bracket 3 is fixed on the double-sided adjusting plate 5. The internal cavity of the double-sided adjusting plate 5 is connected to the U-shaped cooling pipes 6 on both sides. Multiple disturbance wheels 17 are rotatably connected to the inner side of the U-shaped cooling pipe 6 at the bottom via pins. A guide shell 13 is installed at the bottom of the double-sided adjusting plate 5. A hydraulic push rod 14 is fixedly installed on the inner wall of the guide shell 13. A drive rack 15 is fixedly connected to the output end of the hydraulic push rod 14. Multiple driven gears 16 mesh on strip 15. The driven gears 16 are fixedly connected to the pin shaft. The upper guide assembly includes an upper guide tube 11 fixed to the bottom of the double-sided adjustment plate 5. A docking hollow magnetic seat 10 is rotatably connected to the bottom of the upper guide tube 11. A auger conveying impeller 12 is fixed on the docking hollow magnetic seat 10. The auger conveying impeller 12 is rotatably set inside the upper guide tube 11. The upper guide tube 11 is connected to the U-shaped cooling pipe 6 through the double-sided adjustment plate 5. Multiple storage slots are opened on the cooling seat 7. The inner end face of the storage slot is rotatably connected to the booster impeller 9 through the magnetic rotating shaft. A docking ring 8 that matches the docking hollow magnetic seat 10 is fixedly connected to the top of the storage slot. It should be noted that: the nano-Invar alloy sheet workpiece to be electroplated is fixed in the electroplating frame assembly, then the lifting half-ring 4 on the double-sided adjusting plate 5 is hooked to the lifting bracket 3, and then the lifting bracket 3 is controlled to tilt downwards, allowing the electroplated workpiece to be immersed in the electroplating solution of the electroplating tank 1. During the downward movement of the double-sided adjusting plate 5, the docking hollow magnetic seat 10 will move down to the docking ring 8, and then the docking hollow magnetic seat 10 will magnetically connect with the magnetic shaft of the booster impeller 9, so that the booster impeller 9 and the auger conveyor impeller 12 rotate as a whole through the docking hollow magnetic seat 10. As the electroplating continues, the electroplating solution around the electroplated workpiece will continue to heat up. To avoid increasing the risk of hydrogen embrittlement of the nano-Invar alloy sheet workpiece, the heat exchange and cooling mechanism at the bottom of the cooling seat 7 is used to quickly cool the electroplating solution at the bottom of the electroplating tank 1. Then the booster impeller 9 is controlled to rotate, and the electroplating solution is immersed in the electroplating solution of the auger conveyor 12. Simultaneously, the rotating impeller 12 of the auger conveyor and the rotating booster impeller 9 increase the fluidity of the low-temperature electroplating solution at the bottom and allow the low-temperature electroplating solution to gather at the bottom of the upper guide tube 11. The low-temperature electroplating solution enters the gap of the rotating auger conveyor impeller 12 through the notch at the bottom of the upper guide tube 11, allowing the rotating auger conveyor impeller 12 to transport the low-temperature electroplating solution to each U-shaped cooling tube 6, thereby achieving the cooling operation of each U-shaped cooling tube 6 and keeping the workpiece to be electroplated at a lower temperature. At the same time, the hydraulic push rod 14 is activated to push the drive rack 15 back and forth, so that the moving drive rack 15 can drive multiple driven gears 16 to rotate. The rotation of the driven gears 16 will drive multiple disturbance wheels 17 to rotate synchronously through the pin shaft, thereby increasing the fluidity of the electroplating solution below and facilitating the disturbance of the low-temperature electroplating solution to both sides of the double-sided adjustment plate 5. The benefits mentioned above are: the temperature of the electroplating solution environment around the workpiece can be controlled during the electroplating process, avoiding the continuous rise in temperature of the electroplating solution and the generation of hydrogen gas during the electroplating process, reducing the risk of hydrogen embrittlement of the workpiece during the electroplating process (the phenomenon in which hydrogen atoms penetrate into the metal matrix during the electroplating process, leading to a decrease in the plasticity and toughness of the material, and even brittle fracture under stress), and ensuring the overall electroplating quality of the workpiece. The double-sided adjustment plate 5 has multiple installation slots, and multiple exchange holes are provided on the inner side walls of the front and rear sides of the installation slots. The liquid storage tank 18 is connected to the installation slot through the adjustment pipe 20. Multiple adjustment holes corresponding to the exchange holes are provided on the inner side walls of the front and rear sides of the adjustment pipe 20. The adjustment pipe 20 is equipped with a liquid inlet perforated pipe 21 at the adjustment hole. Both ends of the liquid inlet perforated pipe 21 are connected to a unidirectional component for unidirectional transportation of acid and alkali liquids through the liquid guide pipe 22. Furthermore, the top of the double-sided adjusting plate 5 is fixedly connected to the liquid storage tank 18 through a protective shell. The multiple liquid storage tanks 18 are respectively filled with acidic and alkaline solvents for adjusting the pH of the electroplating solution. The liquid storage tank 18 is rotatably connected to the adjusting pipe 20 through the steering seat 19. The one-way component includes a blocking ball 25 that slides on the outer wall of the end of the liquid guide pipe 22. The blocking ball 25 has a flow hole and is locked in the adjusting hole of the adjusting pipe 20. The two liquid guide pipes 22 are connected by a compensating spring 23. The liquid guide pipe 22 is slidably connected to the inner wall of the liquid inlet perforated pipe 21. A permeation plug 24 is fixedly connected to the end of the liquid guide pipe 22. The volume of the permeation plug 24 is smaller than the internal cavity of the blocking ball 25.

[0023] It should be noted that during the electroplating process, the pH level of the electroplating solution is monitored in real time using a pH monitoring instrument. This is an existing technology and will not be elaborated upon further. If an abnormal pH value is detected in the electroplating solution, the adjusting tube 20 is rotated within the mounting slot of the double-sided adjusting plate 5 via the steering seat 19. This causes the blocking ball 25 to rotate into the exchange hole of the mounting slot. During this rotation, the blocking ball 25 is first squeezed by the inner wall of the mounting slot, causing the permeation plug 24 to press against the inner wall of the blocking ball 25. This, in turn, pushes the liquid guide tube 22 to compress the compensating spring 23. At this time, the pH adjusting solvent enters through the liquid inlet perforated tube 21. The liquid enters the liquid guide tube 22 and then enters the plug ball 25. After the plug ball 25 moves into the exchange hole of the mounting groove, it will move outward, causing the permeation plug 24 to separate from the inner wall of the plug ball 25. This will press and block the sliding part between the plug ball 25 and the liquid guide tube 22, and slightly stretch the compensation spring 23 to ensure a tight seal and prevent the acid-base adjustment solvent in the regulating tube 20 from mixing with the electroplating solution. During this movement, the original acid-base adjustment solvent in the plug ball 25 will flow through the edge of the permeation plug 24, allowing a small amount of the original acid-base adjustment solvent in the plug ball 25 to enter the electroplating solution through the flow hole at its end. The advantages mentioned above are: timely adjustment of the pH of the electroplating solution, avoiding damage to the electroplated workpiece; In use, the nano-Invar alloy sheet workpiece to be electroplated is fixed in the electroplating frame assembly. Then, the lifting half-ring 4 on the double-sided adjusting plate 5 is hooked to the lifting bracket 3. The lifting bracket 3 is then tilted downwards to immerse the workpiece in the electroplating solution of the electroplating tank 1. As the double-sided adjusting plate 5 moves downwards, the docking hollow magnetic seat 10 moves down to the docking ring 8, and then magnetically engages with the magnetic shaft of the booster impeller 9, causing the booster impeller to... The pressure impeller 9 rotates as a unit with the auger conveyor impeller 12 via the docking hollow magnetic base 10. As electroplating continues, the electroplating solution around the workpiece will continuously heat up. To avoid increasing the risk of hydrogen embrittlement of the nano-Invar alloy sheet workpiece, the heat exchange and cooling mechanism at the bottom of the cooling base 7 rapidly cools the electroplating solution at the bottom of the electroplating tank 1. Subsequently, the pressure impeller 9 is controlled to rotate, which in turn drives the auger conveyor impeller 12 to rotate synchronously. The rotation of the pressure impeller 9 increases the flow of the low-temperature electroplating solution at the bottom. The system allows the low-temperature electroplating solution to gather at the bottom of the upper conduit 11. The solution then enters the gap of the rotating auger conveyor impeller 12 through a notch at the bottom of the upper conduit 11. The rotating auger conveyor impeller 12 delivers the low-temperature electroplating solution to each U-shaped cooling tube 6, achieving cooling of each U-shaped cooling tube 6. This keeps the workpiece to be electroplated at a lower temperature. Simultaneously, the hydraulic push rod 14 is activated to reciprocate the drive rack 15, causing it to drive multiple driven gears 16 to rotate. The rotation of the driven gears 16 drives multiple agitator wheels 17 to rotate synchronously via pins, thereby increasing the fluidity of the electroplating solution below. This facilitates the agitation of the low-temperature electroplating solution to both sides of the double-sided adjustment plate 5, ensuring that the temperature of the surrounding electroplating solution environment is controllable during electroplating. This prevents the electroplating solution from continuously heating and generating hydrogen gas, reducing the risk of hydrogen embrittlement and ensuring the overall electroplating quality of the workpiece. During the electroplating process, the pH level of the electroplating solution is monitored in real time using a pH monitoring instrument. This is an existing technology and will not be elaborated further. If an abnormal pH value is detected in the electroplating solution, the adjusting tube 20 is rotated within the mounting slot of the double-sided adjusting plate 5 via the steering seat 19. This causes the blocking ball 25 to rotate into the exchange hole of the mounting slot. During this rotation, the blocking ball 25 is first squeezed by the inner wall of the mounting slot, causing the permeation plug 24 to press against the inner wall of the blocking ball 25. This pushes the liquid guide tube 22 to compress the compensating spring 23. At this time, the acid-base adjusting solvent enters the liquid guide tube 22 through the liquid inlet perforated tube 21 and then enters the blocking ball 25. Inside, after the plugging ball 25 moves into the exchange hole of the mounting slot, the plugging ball 25 will move outward, causing the permeation plug 24 to separate from the inner wall of the plugging ball 25. This will press and block the sliding part between the plugging ball 25 and the liquid guide tube 22, and slightly stretch the compensation spring 23 to ensure a tight seal and prevent the acid-base adjusting solvent in the regulating tube 20 from mixing with the electroplating solution. During this movement, the original acid-base adjusting solvent in the plugging ball 25 will flow through the edge of the permeation plug 24, allowing a small amount of the original acid-base adjusting solvent in the plugging ball 25 to enter the electroplating solution through the flow hole at its end. This will achieve timely adjustment of the acidity and alkalinity of the electroplating solution and prevent damage to the electroplated workpiece.
