Technical Field

[0001] The invention relates to the technical field of electroplating, and in particular to a metal tube electroplating machine. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to make a layer of metal film adhere to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance and enhancing aesthetics. For example, coins are processed by electroplating.

[0003] During electroplating, the plating metal or other insoluble material acts as the anode and the workpiece to be plated acts as the cathode. The cations of the plating metal are reduced on the surface of the workpiece to be plated to form a plating layer.

[0031] The present application is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0032] A metal tube electroplating machine, such as Figure 1 and Figure 2As shown, it includes a platform 1, on which a plating tank 11 is provided, in which a plating solution is placed, and in which an impeller 111 for driving the circulation of the plating solution is provided, and a frame 2 is provided on the upper side of the platform 1. A driving member 21 and a pressing plate 22 are provided on the frame 2, and the driving member 21 is used to drive the pressing plate 22 to move toward the plating tank 11. A driving wheel 221 is rotatably provided on the pressing plate 22, and a motor 222 is also provided on the pressing plate 22, and the driving wheel 221 is driven by the motor 222. A supporting wheel 112 is rotatably provided in the plating tank 11, and the driving wheel is used to abut against the metal pipe from the upper side, and the supporting wheel 112 is also used to abut against the metal pipe, and a plurality of supporting wheels 112 are provided. In a specific implementation, the metal tube can be clamped between the support wheel 112 and the driving wheel 221. Both the driving wheel 221 and the support wheel 112 can be wrapped with rubber, and the metal tube is driven to rotate by generating friction, so that the metal tube is in uniform contact with the electrolyte during the rotation process, thereby improving the metal tube and the electrolyte. like Figure 1 and Figure 2 As shown, the support wheels 112 are respectively arranged on each tank wall of the electroplating tank 11, and the support wheels 112 include a rod body 113 and a wheel body 114, and the wheel body 114 is rotatably connected to the rod body 113, and the rod body 113 is arranged on the tank wall of the electroplating tank 11. In specific implementation, the metal pipe can be supported from all directions, further improving the stability of the metal pipe when rotating. In other embodiments, the support wheels 112 can also be arranged at equal intervals along the length direction of the platform 1, so that the support wheels 112 can support the metal pipe from all positions, further improving the stability of the metal pipe when rotating.

[0033] like Figure 1 and Figure 2 As shown, a driving gear 223 is fixedly provided on the rotating shaft of the motor 222, and a transmission gear 224 is fixedly provided on the driving wheel 221. The driving gear 223 and the transmission gear 224 are meshed with each other, and when the driving wheel 221 is extended into the electroplating tank 11, the motor 222 cannot enter the electroplating tank 11. In a specific implementation, the motor 222 is embedded in the pressing plate 22, and when the driving wheel 221 is immersed in the electroplating solution, the motor 222 will not be immersed therewith, thereby reducing the situation where the motor 222 is affected by the electroplating solution and also reducing the waste of the electroplating solution.

[0034] like Figure 1 and Figure 2 As shown, the rod body 113 at the bottom of the electroplating tank 11 is slidably connected to the platform 1, and a pusher 12 is provided in the platform 1 to push the rod body 113 toward the pressing plate 22. In a specific implementation, the pusher 12 includes an oil cylinder or an air cylinder 225, and the pusher 12 can push up the rod body 113 to lift the metal tube out of the electroplating tank, and can also press the metal tube to reduce the situation of the metal tube falling.

[0035] like Figure 1 and Figure 3 As shown, both ends of the pressure plate 22 in the length direction are provided with clamping claws 23, and the clamping claws 23 include a claw plate 231 and two claw bodies 234. The two claw bodies 234 are hingedly arranged on the claw plate 231, and the claw plate 231 is fixedly connected to the pressure plate 22. A driving rod 232 is arranged on the claw plate 231, and the driving rod 232 is slidably connected to the claw plate 231. Two connecting rods 233 are arranged at the end of the driving rod 232, one end of the connecting rod 233 is hinged to the driving rod 232, and the other end of the connecting rod 233 is hinged to the claw body 234. When the connecting rod 233 is parallel, the claw body 234 is stretched to both sides, and when the connecting rod 233 is not in a parallel state, the claw body 234 is pulled toward the middle. In specific implementation, when the driving rod 232 moves in the same direction, it can drive the claw body 234 from a clamped state to a loose state and then to a clamped state.

[0036] like Figure 1 and Figure 3 As shown, a cylinder 225 is fixedly arranged on the pressing plate 22, and a push rod 226 is fixedly arranged on the piston rod of the cylinder 225. The push rod 226 is slidably connected to the pressing plate 22, and the push rod 226 is used to push the driving rod 232 to move and control the clamping claw 23. The push rod 226 is arranged on the upper side of the driving rod 232, and a transmission rod 235 is arranged on the driving rod 232 towards the push rod 226. The transmission rod 235 is fixedly connected to the driving rod 232, and the transmission rod 235 is transmission-connected to the push rod 226. A sliding groove 227 is provided on the pressing plate 22 corresponding to the transmission rod 235, and the transmission rod 235 is slidably connected in the sliding groove 227. In specific implementation, since the push rod 226 is arranged on the upper side of the driving rod 232, the cylinder 225 will not be immersed in the electrolyte together with the pressing plate 22, thereby reducing the situation where the cylinder 225 is affected by the electrolyte.

[0037] like Figure 1 and Figure 3 As shown, an arc-shaped ring 236 is fixedly connected to the claw body 234, and an abutting wheel 237 is rotatably connected inside the arc-shaped ring 236. A plurality of abutting wheels 237 are provided and are used to abut the metal pipe. In specific implementation, after the clamping claw 23 holds the metal pipe, the metal pipe can still rotate under the drive, reducing the situation where the arc-shaped ring 236 abuts against the metal pipe and causes the metal pipe to stop rotating.

[0038] like Figure 1 and Figure 3As shown, the transmission rod 235 on one side is fixedly connected to the push rod 226, and the transmission rod 235 on the other side is independently arranged with the push rod 226 and can be pushed by the push rod 226. The push rod 226 can interfere with the independently arranged transmission rod 235 during the movement, thereby pushing the transmission rod 235 to move, so as to drive the clamping claw 23 to clamp. A spring 228 is also provided at the independently arranged transmission rod 235, one end of the spring 228 is fixedly connected to the groove wall of the sliding groove 227, and the other end of the spring 228 is fixedly connected to the transmission rod 235. The spring 228 has a tendency to pull the transmission rod 235 toward the spring 228 so that the clamping jaws 23 are in a clamped state. During the movement of the push rod 226 from the transmission rod 235 on one side toward the transmission rod 235 on the other side, the clamping jaws 23 on both sides change in the following states: the clamping jaws 23 on one side of the transmission rod 235 are clamped, and the clamping jaws 23 on one side of the transmission rod 235 are independently arranged are loosened; the clamping jaws 23 on both sides are loosened; the clamping jaws 23 on one side of the transmission rod 235 are loosened, and the clamping jaws 23 on one side of the transmission rod 235 are independently arranged are clamped; the clamping jaws 23 on both sides are clamped. During specific implementation, the push rod 226 can move along the pressure plate 22 during the movement. The push rod 226 can perform multiple actions during the movement, including loosening the clamping jaws 23, clamping the metal tube from both sides, and clamping the metal tube from one side. When the metal tube is electroplated, the clamping position can be loosened to allow the clamping position to be electroplated, and the metal tube can also be supported on the other side to reduce the loosening of the metal tube.

[0039] Working principle: When working, the metal tube is first clamped by the clamping claw 23, and then the pressure plate 22 is pressed downward to send the metal tube into the electrolytic cell for processing. During the processing, the metal tube is rotated by the driving wheel 221, and the metal tube can be electroplated during the rotation process, thereby improving the uniformity of the electroplating.

[0040] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
