[0002] Electroplating corrosion-resistant treatment for square tubes is a method to improve the corrosion resistance of the square tube surface. By immersing the square tube in an electroplating tank and using an external DC power supply, the metal ions in the electroplating solution in the electroplating tank are reduced to metal atoms on the surface of the square tube by electrons, forming a uniform electroplating layer, thereby improving the corrosion resistance of the square tube.

[0003] When using an electroplating device to electroplat square tubes, the square tube is usually placed inside a wire mesh frame, and then the wire mesh frame is immersed in the electroplating solution inside the electroplating tank. The electroplating solution enters the wire mesh frame through the holes on the surface of the wire mesh frame and comes into contact with the surface of the square tube. However, the positions of the wire mesh frame and the square tube remain fixed throughout the electroplating process. The surface of the square tube that is in contact with the wire mesh frame cannot make good contact with the electroplating solution, resulting in incomplete electroplating treatment and poor electroplating effect on the surface of the square tube. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the positions of the wire mesh frame and the square tube are fixed throughout the electroplating process, and the surface of the square tube that is in contact with the wire mesh frame cannot make good contact with the electroplating solution, resulting in incomplete electroplating treatment and poor electroplating effect on the surface of the square tube.

The first gear and the second gear mesh. A hydraulic rod is installed on one side of the top of the electroplating tank, and the output rod of the hydraulic rod is fixedly connected to one side of the frame rod.

[0021] Example 1, such as Figure 1-3 As shown, a square tube processing electroplating corrosion-resistant treatment device includes an electroplating tank 1, a drain pipe 3 is provided on one side of the electroplating tank 1, a control valve is provided on the outer surface of the drain pipe 3, a plurality of anode plates 4 are fixedly connected to the inner wall of the electroplating tank 1, a power supply box 5 is provided on the outer surface of the electroplating tank 1, the anode plates 4 and the power supply box 5 are connected by wires, and an auxiliary device 2 is provided at the top of the electroplating tank 1 to improve the electroplating effect of the square tube.

[0022] Reference Figure 1-4As shown in this embodiment: the auxiliary device 2 includes two support rods 21. The bottom end of the support rod 21 is fixedly connected to the top end of the electroplating tank 1. A sliding rod 22 is slidably connected to the inner wall of the support rod 21. A frame rod 23 is fixedly connected to the top end of the sliding rod 22. A rotating shaft 25 is rotatably connected to the inner wall of the frame rod 23. Two connecting rods 26 are fixedly connected to the outer surface of the rotating shaft 25. A shaft 211 is rotatably connected to the bottom end of the connecting rod 26. A groove cylinder 212 is fixedly connected to one end of the two shafts 211 that are close to each other. Several through holes are opened on the outer surface of the groove cylinder 212. A servo motor 28 is provided on the outer surface of one connecting rod 26. The output end of the servo motor 28 is connected to a first gear 29 through a coupling. The shaft 211 on the outer surface of the connecting rod 26 with the servo motor 28 is away from the groove cylinder. One end of 212 is fixedly connected to a second gear 210, and the first gear 29 meshes with the second gear 210. A hydraulic rod 24 is provided on one side of the top of the electroplating tank 1. The output rod of the hydraulic rod 24 is fixedly connected to one side of the frame rod 23. By setting the tank cylinder 212, when the electroplating corrosion-resistant treatment device is used to electroplat the surface of the square tube, the rotating shaft 25 on one side of the top of the frame rod 23 is rotated to control the two connecting rods 26 and the tank cylinder 212 to tilt away from the frame rod 21. Then, several square tubes are placed inside the tank cylinder 212. The rotating shaft 25 is then rotated to control the connecting rods 26 and the tank cylinder 212 to rotate perpendicular to the electroplating tank 1. The hydraulic rod 24 is operated by the power supply box 5 to retract the output rod of the hydraulic rod 24, which drives the frame rod 23 to move downward, so that the two sliding rods 22 The bracket 21 moves downwards and retracts into its inner wall, immersing the lower half of the tank 212 at the bottom of the connecting rod 26 into the electroplating solution. The servo motor 28 is positioned above the surface of the electroplating solution. The power supply box 5 then powers the anode plate 4 inside the electroplating tank 1, causing the servo motor 28 to rotate. This drives the first gear 29 to rotate, and the meshing of the first gear 29 with the second gear 210 rotates the second gear 210 and a shaft 211, causing the tank 212 to rotate slowly. The square tube inside the tank 212 slides or rolls within the tank 212, changing position as the tank rotates. The electroplating solution enters the tank 212 through the through-holes on its outer surface and contacts the outer surface of the square tube, where electrons are reduced to form plating solution. Metal atoms form a uniform electroplating layer, thereby improving the corrosion resistance of the square tube. After electroplating, the operation of the servo motor 28 is stopped, and the hydraulic rod 24 is operated to control the output rod of the hydraulic rod 24 to extend and push the slide rod 22 to slide upward on the inner wall of the support rod 21, so that the frame rod 23 and the tank cylinder 212 are raised, causing the tank cylinder 212 to detach from the interior of the electroplating tank 1. Then, the connecting rod 26 is pushed to rotate through the rotating shaft 25 to tilt away from the support rod 21, so that the square tube located inside the tank cylinder 212 can be taken out. Opening the control valve at the top of the drain pipe 3 can allow the electroplating solution inside the electroplating tank 1 to be discharged through the drain pipe 3. By setting the auxiliary device 2, by inserting the square tube into the tank cylinder 212 with surface openings, the lower half of the surface of the tank cylinder 212 is immersed in the electroplating solution during electroplating.The servo motor 28 drives the tank 212 to rotate slowly, causing the square tube inside the tank 212 to slide or roll and change position within the tank 212, thus improving the contact between the square tube surface and the electroplating solution. This enhances the effectiveness and comprehensiveness of the electroplating process on the square tube surface using the electroplating equipment.

[0023] Reference Figure 2-4 As shown in this embodiment: baffle rings 213 are fixedly connected to both ends of the inner wall of the tank cylinder 212. The baffle rings 213 are located at the outer edge of the inner wall of the tank cylinder 212. By setting the baffle rings 213, the position of the square tube inside the tank cylinder 212 can be restricted, so as to avoid the square tube from leaving the inside of the tank cylinder 212 when it moves inside the tank cylinder 212. Two push plates 214 are fixedly connected to the outer surface of the tank cylinder 212. The two push plates 214 are located on opposite sides of the outer surface of the tank cylinder 212. When the tank cylinder 212 rotates, the push plates 214 stir the electroplating solution, which can accelerate the diffusion rate of ions in the electroplating solution, which is conducive to the deposition of metal ions on the surface of the square tube and improves the uniformity of the coating.

[0024] Reference Figure 2-4 As shown in this embodiment: a support rod 215 is fixedly connected to one side of the frame rod 23, and the end of the support rod 215 away from the frame rod 23 is fixedly connected to the output rod side of the hydraulic rod 24. By setting the support rod 215, the connection between the frame rod 23 and the output rod of the hydraulic rod 24 can be strengthened, thereby improving the stability of the connection structure between the frame rod 23 and the output rod of the hydraulic rod 24.

[0025] Reference Figure 2-5As shown in this embodiment: one end of the rotating shaft 25 is provided with a limiting component 27 that can fix the angle between the rotating shaft 25 and the groove cylinder 212. The limiting component 27 includes a protruding rod 272. An insert rod 273 is slidably connected to the bottom of the inner wall of the protruding rod 272. A spring 274 is provided on the outer surface of the insert rod 273. The two ends of the spring 274 are fixedly connected to one end of the insert rod 273 and one side of the protruding rod 272, respectively. Several insertion holes 271 are opened on one side of the outer surface of the electroplating tank 1. Pulling the insert rod 273 causes the insert rod 273 to move away from the protruding rod 272 to compress the spring 274. Holding the outer surface of the protruding rod 272 makes it easier to control the rotation and angle adjustment of the rotating shaft 25, the connecting rod 26, and the groove cylinder 212. When located on the side away from the support rod 21, the insertion rod 273 is released and restored to its original state by the spring 274. Pulling the insertion rod 273 to slide on the inner wall of the protrusion rod 272 allows one end of the insertion rod 273 to be inserted into a hole 271 on the outer surface of the electroplating tank 1. This can fix the angle between the protrusion rod 272, the rotating shaft 25, and the tank cylinder 212 and the electroplating tank 1, which facilitates the placement and removal of the square tube inside the tank cylinder 212 and improves the stability of the auxiliary device 2 during operation. Two protrusions 275 are fixedly connected to the end of the insertion rod 273 away from the protrusion rod 272. The two protrusions 275 are located on opposite sides of the outer surface of the insertion rod 273. Holding the two protrusions 275 on the outer surface of the insertion rod 273 makes it easier to pull the insertion rod 273 and control its movement.

[0026] Working principle: When electroplating the surface of square tubes using the electroplating corrosion-resistant treatment device, pulling the insertion rod 273 moves it away from the protruding rod 272, compressing the spring 274. Then, holding the outer surface of the protruding rod 272, the control shaft 25, connecting rod 26, and groove cylinder 212 rotate to adjust their angles, controlling the two connecting rods 26 and groove cylinder 212 to tilt away from the support rod 21. Several square tubes are then placed inside the groove cylinder 212. The rotating shaft 25 is then rotated to control the connecting rods 26 and groove cylinder 212 to rotate perpendicular to the electroplating tank 1. The insertion rod 273 is then released, and the spring 274 passes through. 4. To restore the original state, pull the insertion rod 273 to slide on the inner wall of the protruding rod 272, so that one end of the insertion rod 273 is inserted into a hole 271 on the outer surface of the electroplating tank 1. Fix the angle between the protruding rod 272, the rotating shaft 25, the tank cylinder 212 and the electroplating tank 1. Then, control the operation of the hydraulic rod 24 through the power supply box 5 to make the output rod of the hydraulic rod 24 retract and drive the frame rod 23 to move downward, so that the two sliding rods 22 move downward on the inner wall of the frame rod 21 and retract into the frame rod 21. So that the lower half of the tank cylinder 212 at the bottom of the connecting rod 26 is immersed in the electroplating solution. Control the servo motor 28 to be above the surface of the electroplating solution. Then, the power supply box 5 controls the anode plate 4 inside the electroplating tank 1 to be energized, and the servo motor 28 drives the first gear 29 to rotate. The meshing of the first gear 29 with the second gear 210 drives the second gear 210 and a shaft 211 to rotate, causing the tank cylinder 212 to rotate slowly. The square tube located inside the tank cylinder 212 will slide or roll and change position inside the tank cylinder 212 as the tank cylinder 212 rotates. The electroplating solution will enter the tank cylinder 212 through the through holes on the outer surface of the tank cylinder 212 and come into contact with the outer surface of the square tube. On the surface of the square tube, electrons are obtained and reduced to metal atoms. A uniform electroplating layer is formed, thereby improving the corrosion resistance of the square tube. After electroplating is completed, the operation of the servo motor 28 is stopped, and the hydraulic rod 24 is operated to control the output rod of the hydraulic rod 24 to extend and push the slide rod 22 to slide upward on the inner wall of the frame rod 21, so that the frame rod 23 and the tank cylinder 212 are raised and the tank cylinder 212 is removed from the inside of the electroplating tank 1. Then, the connecting rod 26 is pushed to rotate through the rotating shaft 25 to tilt away from the frame rod 21, so that the square tube located inside the tank cylinder 212 can be taken out. Opening the control valve at the top of the drain pipe 3 can allow the electroplating solution inside the electroplating tank 1 to be discharged through the drain pipe 3.
