Description

Technical Field

[0001] The present invention relates to the technical field of stripping plating for metal fittings, and specifically relates to a stripping plating device and an operation method for the production of metal fittings. Background Art

[0002] In the production and processing of metal fittings, the stripping plating process is an important link, and its main function is to remove the existing plating layer on the metal surface for subsequent processing or re-plating. There are many problems in the actual use of existing metal fitting stripping plating devices. On the one hand, most stripping plating devices place the motor near or even in direct contact with the stripping plating solution. A large amount of heat generated by the motor during long-term operation will be absorbed by the stripping plating solution, which not only affects the chemical properties and quality of the stripping plating solution, but also accelerates the evaporation of the stripping plating solution, increasing production costs and maintenance difficulties. At the same time, the stirring structure of the existing device often fails to fully ensure the effective contact between the parts to be stripped and the stripping plating solution, resulting in low stripping plating efficiency. On the other hand, during the stripping plating process, a large amount of debris will remain at the bottom of the stripping plating tank. Traditional stripping plating devices lack an effective self-cleaning mechanism and usually require frequent manual cleaning, which not only consumes a lot of manpower and material resources, but also easily leads to incomplete cleaning, affecting the quality of subsequent stripping plating operations. On the other hand, in the electroplating process, as the plating process progresses, the fixture serving as the support for the plated parts is also plated with various corresponding metal plating layers. Since the fixture needs to be used repeatedly, the plating layer on the fixture must be completely stripped when plating the next batch of parts after plating a batch of parts, otherwise the plating solution will be contaminated. Fixtures are generally made of copper or stainless steel, and the stripping plating process for fixture plating layers must meet the following requirements: one is that the plating layer is stripped quickly and completely, and the other is that the fixture itself is not corroded. During stripping plating, the parts to be stripped are placed in the stripping plating tank and soaked. In some processes, electro-stripping plating is used to accelerate the stripping plating progress. In the prior art, in order to accelerate the stripping plating speed, in some processes, the stirring motor is placed in the stripping plating tank, and the stirring motor drives the stripping plating solution to flow. However, in the existing operation, when the stirring motor is placed in the stripping plating tank, the heat generated by the motor will cause the stripping plating solution to heat up, and too high a temperature will accelerate the evaporation of the stripping plating solution, resulting in waste of the stripping plating solution and increased production costs.

[0003] Therefore, there is an urgent need to design a metal fitting stripping plating device that can overcome the above defects to improve the stripping plating efficiency, reduce the maintenance cost and ensure the stripping plating quality. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose a metal fitting stripping plating device and an operation method.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: A stripping device for metal fitting production, including a stripping tank. On one outer wall of the stripping tank, there is a placement groove, and a motor is fixed to the inner wall of the placement groove by bolts. One end of the motor is provided with a limit ring. One outer wall of the motor is fixed to a fixed rod by bolts, and the bottom end of the fixed rod is fixed to a support plate by bolts. On the outer wall of the output shaft of the motor, there are multiple stirring blades distributed at equal angles. On the opposite inner walls of the stripping tank, there are bearing blocks, and fixing blocks are placed on the tops of the bearing blocks. A placement box is arranged on the outer wall of the fixing block. Through holes are provided on the outer walls of the fixing block and the bearing block, and inserting rods are inserted into the interiors of the through holes.

[0006] Preferably: The support plate is fixed to one outer wall of the stripping tank by bolts, and a discharge port is arranged on the bottom outer wall of the stripping tank.

[0007] Preferably: The placement groove and the motor are both inclined, and the placement box is made of insulating material.

[0008] Preferably: Multiple square openings are arranged at equal distances at the bottom of the placement box, and multiple strip-shaped grooves are arranged at equal distances on one inner wall of the placement box.

[0009] Preferably: A liquid outlet pipe is arranged inside the discharge port, and a mounting seat is arranged inside the liquid outlet pipe. A rotating rod is arranged on the bottom outer wall of the mounting seat, and one outer wall of the rotating rod is rotatably connected to multiple fan blades distributed at equal distances through a sealed bearing.

[0010] Preferably: A liquid outlet valve is arranged on the outer wall of the liquid outlet pipe, and a sealed sleeve is arranged on the bottom outer wall of the stripping tank. The inner wall of the sealed sleeve fits with the liquid outlet pipe.

[0011] Preferably: A base is arranged on the inner wall of the placement box, and a temperature sensor is arranged on the inclined surface of the top of the base. The outer wall of the temperature sensor is sprayed with an anti-corrosion material.

[0012] Preferably, when the stripping device is in use, the motor is fixed outside the stripping solution to prevent a large amount of heat generated by the long-term operation of the motor from being completely absorbed by the stripping solution, which affects the quality of the stripping solution, thereby reducing the evaporation of the stripping solution. The stirring blade is located in the stripping solution. When the motor rotates, the stirring blade drives the stripping solution to flow. The placement box divides the space in the stripping tank, causing the stripping solution passing through the strip-shaped groove to form a circulating flow on both sides of the placement box, thereby increasing the effective contact between the workpiece to be stripped and the stripping solution. The connection of the insertion rod facilitates the fixing and disassembly of the placement box, making it easy to clean the debris inside the placement box. When the stripping solution flows through the liquid outlet pipe, the fan blade rotates driven by the liquid, creating a vortex in the stripping solution, which can accelerate the movement of the debris at the bottom of the stripping tank, reduce the residue of the debris at the bottom of the stripping tank, improve the self-cleaning effect, and reduce the difficulty of manual cleaning. The temperature sensor monitors the temperature of the stripping solution in real time, facilitating the staff to add the stripping solution or take other technical measures in a timely manner according to the detection results to achieve the best stripping environment.

[0013] A stripping operation method for a stripping device used in the production of metal fittings, characterized by including the following operations; I. Device preparation stage Installation and fixation: Place the stripping tank stably in a suitable working area. Fix the motor in the placement groove on the outer wall of one side of the stripping tank. Through the cooperation of the limit ring, fixed rod, and support plate, ensure that the motor is firmly installed and located outside the stripping solution. Install bearing blocks on the inner walls of the opposite sides of the stripping tank. Place the fixed block on top of the bearing block, align the through holes of the fixed block and the bearing block, and insert the insertion rod to fix the placement box. The placement box is made of insulating material, and the square opening at the bottom and the strip-shaped groove on the inner wall ensure the flow of the stripping solution; Stripping solution addition: Open the opening at the top of the stripping tank and add an appropriate amount of stripping solution into the stripping tank. The height of the stripping solution should ensure that the metal fittings to be stripped can be completely immersed, and at the same time, the stirring blade is in the stripping solution. II. Stripping operation stage Placement of metal fittings: Place the metal fittings to be stripped into the placement box. The placement box divides the space in the stripping tank, and the stripping solution forms a circulating flow from both sides of the placement box through the strip-shaped groove, ensuring full contact between the metal fittings and the stripping solution; Start stirring: Connect the power supply of the motor. The motor drives the stirring blade on the output shaft to rotate. The stirring blade agitates the stripping solution, causing the stripping solution to flow in the stripping tank, enhancing the effective contact between the workpiece to be stripped and the stripping solution, and accelerating the stripping reaction speed; Temperature monitoring and regulation: The temperature sensor on the top slope of the inner wall base of the placement box monitors the temperature of the stripping solution in real time. The anti-corrosion material on its outer wall ensures the normal operation of the sensor in a corrosive environment. Personnel can adjust the temperature of the stripping solution through heating or cooling equipment according to the data feedback by the temperature sensor to maintain the best stripping environment; III. Post-stripping treatment stage Debris cleaning: After the stripping is completed, open the liquid discharge valve, and the stripping solution flows out through the discharge port at the bottom of the stripping tank via the liquid discharge pipe. When the stripping solution flows through the liquid discharge pipe, it drives the fan blades on the internal rotating rod to rotate, forming a vortex in the stripping solution, accelerating the movement of debris at the bottom of the stripping tank towards the discharge port, reducing debris residue, and enhancing the self-cleaning effect. Placement box cleaning: Pull out the insertion rod, remove the placement box from the bearing block, clean the residual debris and stripped metal fittings inside the placement box, and reinstall the placement box after cleaning to prepare for the next stripping operation.

[0014] The present invention has the following beneficial effects: 1. Improve the motor layout and ensure the performance of the stripping solution: The motor of the present invention is arranged in the placement groove on one side of the stripping tank and is firmly installed through structures such as fixing rods and support plates, so that the motor is completely outside the stripping solution. This design effectively avoids the direct transfer of heat generated by the long-term operation of the motor to the stripping solution, prevents the stripping solution from changing its chemical properties and accelerating evaporation due to heat, greatly ensures the quality stability of the stripping solution, and reduces the replenishment cost and maintenance frequency of the stripping solution during the production process. At the same time, the stirring blades on the output shaft of the motor extend into the stripping solution. When the motor rotates, it can drive the stripping solution to flow fully, and cooperate with the special structure of the placement box to form a circulating flow inside and outside the box, significantly increasing the contact area and contact efficiency between the parts to be stripped and the stripping solution, and effectively improving the stripping effect and processing efficiency. 2. Design a self-cleaning structure and reduce the maintenance cost: The components such as the liquid discharge pipe, mounting seat, rotating rod and fan blades arranged at the discharge port at the bottom of the stripping tank constitute an efficient self-cleaning system. When the stripping solution is discharged through the liquid discharge pipe, the flow of the liquid drives the fan blades to rotate, forming a vortex effect at the bottom of the stripping tank, which can quickly stir and drive the debris deposited at the bottom of the tank to be discharged with the liquid flow. This design does not require frequent manual cleaning of the debris at the bottom of the tank, not only saves a lot of manpower and material resources, but also ensures the cleanliness inside the stripping tank, avoids the interference of debris residue on the subsequent stripping operation, extends the service life of the stripping device, and reduces the overall maintenance cost.

[0015] 3. Real-time temperature monitoring to ensure the best stripping environment: The temperature sensor arranged on the inner wall of the placement box can monitor the temperature change of the stripping solution in real time and accurately. Since the outer wall of the sensor is sprayed with anti-corrosion material, it can work stably in the strongly corrosive stripping solution environment. According to the data feedback by the temperature sensor, the staff can take measures such as replenishing the stripping solution, adjusting the heating or cooling equipment in time, and accurately control the temperature of the stripping solution within the best process range, providing stable and suitable environmental conditions for the stripping process of metal fittings, thus ensuring the consistency and reliability of the stripping quality, and improving the product qualification rate and production efficiency.

[0023] Working principle: During use, the motor 2 is fixed outside the stripping solution, avoiding that a large amount of heat generated by the long-term operation of the motor 2 is completely absorbed by the stripping solution, which affects the quality of the stripping solution, thereby reducing the evaporation of the stripping solution. The stirring blades 7 are located in the stripping solution. When the motor 2 rotates, the stirring blades 7 drive the stripping solution to flow. The placement box 9 divides the space in the stripping tank 5, so that the stripping solution passing through the strip-shaped grooves forms a circulating flow on both sides of the placement box 9, thereby increasing the effective contact between the parts to be stripped and the stripping solution. The connection through the inserting rod 6 facilitates the fixing and disassembly of the placement box 9, and is convenient for cleaning the sundries in the placement box 9. Open the liquid outlet valve 13. When the stripping solution flows through the liquid outlet pipe 16, the fan blades rotate under the drive of the liquid, thereby forming a vortex in the stripping solution, which can accelerate the movement of the sundries at the bottom of the stripping tank 5, reduce the residue of the sundries at the bottom of the stripping tank 5, improve the self-cleaning effect, and reduce the difficulty of manual cleaning.

[0024] Embodiment 2 Refer to Figure 3 , A stripping device for metal fitting production. Compared with Embodiment 1, in this embodiment, a base 19 is provided on the inner wall of the placement box 9, and a temperature sensor 18 is provided on the inclined surface of the top of the base 19. An anti-corrosion material is sprayed on the outer wall of the temperature sensor 18.

[0025] Working principle: During use, the motor 2 is fixed outside the stripping solution to prevent a large amount of heat generated by the long-term operation of the motor 2 from being completely absorbed by the stripping solution, which may affect the quality of the stripping solution. This reduces the evaporation of the stripping solution. The stirring blade 7 is located in the stripping solution. When the motor 2 rotates, the stirring blade 7 can drive the stripping solution to flow. The placement box 9 divides the space in the stripping tank 5, causing the stripping solution passing through the strip-shaped groove to form a circulating flow on both sides of the placement box 9, thereby increasing the effective contact between the workpiece to be stripped and the stripping solution. The connection of the insertion rod 6 facilitates the fixing and disassembly of the placement box 9, making it easy to clean the debris inside the placement box 9. When the liquid discharge valve 13 is opened and the stripping solution flows through the liquid discharge pipe 16, the fan blade rotates driven by the liquid, thereby forming a vortex in the stripping solution, which can accelerate the movement of the debris at the bottom of the stripping tank 5, reduce the residue of the debris at the bottom of the stripping tank 5, improve the self-cleaning effect, reduce the difficulty of manual cleaning, and the temperature sensor 18 can monitor the temperature of the stripping solution in real time, facilitating the staff to add the stripping solution or take other technical measures in a timely manner according to the detection results to achieve the best stripping environment.

[0026] The device has the following innovations: 1. Improve the motor layout to ensure the performance of the stripping solution: In the present invention, the motor is arranged in the placement groove on one side of the stripping tank and is firmly installed through structures such as fixing rods and support plates, so that the motor is completely outside the stripping solution. This design effectively prevents the heat generated by the long-term operation of the motor from being directly transferred to the stripping solution, preventing the stripping solution from changing its chemical properties and accelerating evaporation due to heat, greatly ensuring the quality stability of the stripping solution, reducing the replenishment cost and maintenance frequency of the stripping solution during the production process. At the same time, the stirring blade on the output shaft of the motor extends into the stripping solution. When the motor rotates, it can drive the stripping solution to flow fully. Combined with the special structure of the placement box, the stripping solution forms a circulating flow inside and outside the box, significantly increasing the contact area and contact efficiency between the workpiece to be stripped and the stripping solution, and effectively improving the stripping effect and processing efficiency. 2. Design a self-cleaning structure to reduce the maintenance cost: The components such as the liquid discharge pipe, mounting seat, rotating rod and fan blade arranged at the bottom discharge port of the stripping tank constitute an efficient self-cleaning system. When the stripping solution is discharged through the liquid discharge pipe, the flow of the liquid drives the fan blade to rotate, forming a vortex effect at the bottom of the stripping tank, which can quickly stir and drive the debris deposited at the bottom of the tank to be discharged with the liquid flow. This design does not require frequent manual cleaning of the debris at the bottom of the tank, which not only saves a lot of manpower and material resources, but also ensures the cleanliness inside the stripping tank, avoids the interference of debris residue on subsequent stripping operations, extends the service life of the stripping device, and reduces the overall maintenance cost.
