Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, and in particular to a high-efficiency and uniform iron alloy electroplating gold and silver device. Background Technology

[0002] With the increasing demands of modern industry for metal surface performance, electroplating of iron alloys with gold and silver has been widely used in electronics, jewelry, aerospace and other fields. Electroplating with gold and silver can not only give iron alloy products excellent decorative properties, conductivity and corrosion resistance, but also significantly increase their added value.

[0003] A search revealed a Chinese patent (authorization announcement number CN221166830U) disclosing an electroplating equipment for surface treatment of magnesium alloy castings. The equipment includes a suspension structure with an electroplating tank at its lower end. The suspension structure includes support columns, and a crossbeam is fixedly connected between the crossbeams of the support columns. A guide rail is fixedly connected in the middle of the crossbeam, and a displacement structure is provided at the lower end of the guide rail. This displacement structure includes a sliding seat, and a driving structure is internally connected to the lower end of the sliding seat. While this patented technology allows for convenient placement and removal of workpieces from the electroplating tank via the suspension structure, effectively increasing operational convenience and improving work efficiency, the movable support block structure at the bottom of the placement basket supports and holds the magnesium alloy castings placed inside, reducing the contact area between the bottom of the magnesium alloy castings and the bottom of the placement basket, thus making the electroplating process more comprehensive.

[0004] However, the above-mentioned devices still have some drawbacks in actual use. The most obvious one is that the electroplating equipment uses a method of sequentially plating individual alloy castings, which makes the production process obviously intermittent and cannot meet the efficiency requirements of large-scale industrial production. In addition, the existing devices lack an effective electroplating solution stirring mechanism. During the electroplating process, the metal ions in the electroplating solution are continuously consumed. At the same time, due to the heat generated by the electrochemical reaction and the effect of gravity, the electroplating solution is prone to stratification. The upper layer of electroplating solution has a lower concentration and higher temperature, while the lower layer has a higher concentration and lower temperature. This uneven state directly affects the electroplating effect, resulting in problems such as uneven thickness and inconsistent color of the electroplated layer. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main purpose of this utility model is to provide a high-efficiency and uniform iron alloy electroplating gold and silver device.

[0006] The technical solution of this utility model is as follows: a high-efficiency and uniform iron alloy electroplating gold and silver device, including a base, an electroplating tank fixedly connected to the top of the base, two support frames fixedly installed on the top of the base and above the electroplating tank, mounting frames slidably installed on both sides of the support frames, a transmission gear rotatably installed at the center of the bottom of each support frame, a rack fixedly connected to the side of the two mounting frames that are close to each other, the racks meshing with the transmission gears, an electric hoist fixedly installed on the side of the two mounting frames that are far apart from each other, and a placement basket suspended at the bottom of each electric hoist.

[0008] In a preferred embodiment, the electroplating tank is provided with a stirring assembly, which includes two stirring rods a rotatably installed at the center of the electroplating tank. The blades of the two stirring rods a are staggered, and stirring rods b are rotatably installed at both ends of the electroplating tank.

[0010] In a preferred embodiment, the rotation shaft of the stirring rod b extends to the outside of the electroplating tank and is fixedly connected to a sprocket. A chain is driven between the two sprockets. A drive motor c is fixedly installed on one side of the electroplating tank, and the output shaft of the drive motor c is fixedly connected to one of the stirring rods b.

[0011] By adopting the above technical solution, the rotation of the output shaft of the drive motor c can drive one of the stirring rods b to rotate, and through the transmission of the chain and sprocket, the other stirring rod b can rotate synchronously.

[0012] In a preferred embodiment, the rotation shafts of both stirring rods a extend to the outside of the electroplating tank and are fixedly connected to gears a, and the two gears a are meshed together.

[0013] By adopting the above technical solution, the two stirring rods a rotate in opposite directions through meshing gear a.

[0014] In a preferred embodiment, the support frame is provided with a limiting component inside. The limiting component includes a limiting groove formed on both sides of the support frame. Two limiting blocks are slidably connected inside each limiting groove. Each limiting block is fixedly connected to a corresponding mounting frame.

[0015] By adopting the above technical solution, the cooperation of the limiting groove and the limiting block ensures that the mounting frame remains stable during the sliding process, avoids shaking, and ensures the safety and reliability of basket lifting and electroplating operations.

[0016] In a preferred embodiment, a drive motor b is fixedly installed on the outside of the electroplating tank, and the output shaft of the drive motor b is fixedly connected to the rotation shaft of one of the stirring rods a.

[0017] By adopting the above technical solution, the rotation of the output shaft of the drive motor b can drive the stirring rod a to rotate.

[0018] In a preferred embodiment, a drive motor a is fixedly installed at the top center of the support frame, and the output shaft of the drive motor a is fixedly connected to the rotation shaft of the transmission gear.

[0019] By adopting the above technical solution, the rotation of the output shaft of the drive motor a can provide a power source for the rotation of the transmission gear.

[0020] In a preferred embodiment, a controller is fixedly installed on the outside of the electroplating tank, and the drive motors a, b, and c and the electric hoist are all electrically connected to the controller.

[0021] By adopting the above technical solution, automated control can be achieved through the controller.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] Reference Figure 1-4 A high-efficiency and uniform electroplating device for ferroalloys includes a base 1, an electroplating tank 2 fixedly connected to the top of the base 1, two support frames 3 fixedly installed on the top of the base 1 above the electroplating tank 2, mounting frames 13 slidably installed on both sides of the support frames 3, and a transmission gear 15 rotatably installed at the center of the bottom of each support frame 3. A rack 16 is fixedly connected to the side of each mounting frame 13 that is close to each other, and the rack 16 meshes with the transmission gear 15. An electric hoist 14 is fixedly installed on the side of each mounting frame 13 that is far apart from each other. A placement basket 11 is suspended at the bottom of each electric hoist 14. By setting up two mounting frames 13, each equipped with an electric hoist 14 to suspend the placement basket 11, when one placement basket 11 is driving the ferroalloy casting for electroplating, the other placement basket 11 can simultaneously perform loading or unloading operations, making the electroplating process continuous, significantly shortening the production cycle, fully meeting the efficiency requirements of large-scale industrial production, and effectively improving production capacity.

[0032] Specifically, the electroplating tank 2 is equipped with a stirring assembly, which includes two stirring rods a10 rotatably mounted at the center of the electroplating tank 2. The blades of the two stirring rods a10 are staggered. Stirring rods b12 are rotatably mounted at both ends of the electroplating tank 2. The rotation shaft of the stirring rods b12 extends to the outside of the electroplating tank 2 and is fixedly connected to a sprocket 5. The two stirring rods a10 with staggered blades, together with the stirring rods b12 at both ends of the electroplating tank 2, form an all-round stirring effect. The rotation of the output shaft of the drive motor c8 can drive one of the stirring rods b12. The two stirring rods a10 rotate, and through the transmission of chain 6 and sprocket 5, the other stirring rod b12 rotates synchronously. The two sprockets 5 are connected by chain 6. A drive motor c8 is fixedly installed on one side of the electroplating tank 2. The output shaft of the drive motor c8 is fixedly connected to one of the stirring rods b12. The rotation shafts of the two stirring rods a10 extend to the outside of the electroplating tank 2 and are fixedly connected to gears a9. The two stirring rods a10 rotate in opposite directions through the meshing gears a9. This cooperative stirring mode can effectively avoid the stratification phenomenon of the electroplating solution caused by metal ion consumption, electrochemical reaction heat and gravity, so as to make the concentration and temperature of the electroplating solution uniformly distributed, ensure the uniform thickness of the electroplating layer, and thus significantly improve the electroplating quality. The two gears a9 are meshed.

[0033] Specifically, each support frame 3 is internally equipped with a limiting component, including limiting grooves 18 on both sides of the support frame 3. Two limiting blocks 17 are slidably connected inside each limiting groove 18. The cooperation between the limiting grooves 18 and the limiting blocks 17 ensures that the mounting frame 13 remains stable during sliding, preventing shaking and ensuring the safety and reliability of the lifting and lowering of the basket 11 and the electroplating operation. Each limiting block 17 is fixedly connected to its corresponding mounting frame 13. A drive motor b7 is fixedly installed on the outside of the electroplating tank 2. The output shaft of the drive motor b7 is fixedly connected to the rotation shaft of one of the stirring rods a10. A drive motor a4 is fixedly installed at the top center of each support frame 3. The output shaft of the drive motor a4 is fixedly connected to the rotating shaft of the transmission gear 15. The rotation of the output shaft of the drive motor a4 provides a power source for the rotation of the transmission gear 15. A controller is fixedly installed on the outside of the electroplating tank 2. The drive motors a4, b7, c8 and the electric hoist 14 are all electrically connected to the controller. The drive motors a4, b7, c8 and the stirring rod a10 are also electrically connected to the controller to achieve automated control. The equipment operating parameters can be flexibly adjusted according to different electroplating requirements, which not only improves the convenience of operation, but also reduces manual intervention, labor intensity and the risk of human error.

[0034] Working principle: First, the workers place the ferroalloy castings into the corresponding placement baskets 11. Then, the controller starts the drive motor a4. The rotation of the output shaft of the drive motor a4 drives the transmission gear 15 to rotate, so that the two mounting frames 13 move synchronously. Then, the electric hoist 14 can be controlled to lift the placement basket 11 into the electroplating tank 2. While one placement basket 11 is carrying the ferroalloy castings for electroplating, the other placement basket 11 can be loaded or unloaded simultaneously, making the electroplating process continuous and greatly shortening the production cycle. Then, the controller starts the drive motors b7 and c8. The rotation of the output shaft of the drive motor c8 drives one of the stirring rods b12 to rotate. Through the transmission of the chain 6 and sprocket 5, the other stirring rod b12 rotates synchronously. The two stirring rods a10 rotate in opposite directions through the meshing gear a9. This cooperative stirring mode can effectively avoid the stratification phenomenon of the electroplating solution caused by metal ion consumption, electrochemical reaction heat and gravity.
