Description

TECHNICAL FIELD

[0001] The utility model relates to a chromium plating technical field, concretely is a kind of for the conductive device of chromium plating. BACKGROUND

[0002] Chromium plating refers to a metal treatment technology that uses electrolysis to deposit chromium metal on the surface of an object. In this process, the metal workpiece serves as the cathode, and the chromium metal serves as the anode. Through the action of electric current in an electrolyte containing chromium ions, chromium ions are reduced and form a uniform chromium film on the surface of the workpiece. This process can significantly improve the corrosion resistance, wear resistance and appearance of the metal. Chromium plating is not only suitable for metals, but also for the surface treatment of other conductive materials. After chromium plating, the material surface will appear bright silver white, with excellent chemical stability and oxidation resistance, widely used in automobile, machinery, electronics, construction and other industries to meet the high requirements of product quality and appearance.

[0003] The patent document with application number CN202222689205.8 discloses a metal part chromium plating treatment equipment, which includes a chromium plating tank. The front of the chromium plating tank is fixedly installed with a clamping plate placement box. The upper surface of the clamping plate placement box is provided with a groove. The inside of the groove is installed with a manual clamp. One side of the chromium plating tank is fixedly installed with a liquid discharge port. The surface of the liquid discharge port is installed with a manual valve. The metal part chromium plating treatment equipment is set with an electric push rod and a metal placement table. When in use, the electric push rod is extended to drive the metal placement table to move, thereby adjusting the chromium plating of metal parts at different heights. Through the cooperation of the connecting plate, slide rail and slide block, the connecting plate is slid into the slide rail through the slide block, thereby adjusting the size of the placement groove, making the device suitable for metal parts of different sizes, and improving the practicality of the chromium plating treatment equipment. Based on the above patent search and combined with the existing chromium plating process, it is found that in the modern chromium plating technology operation process, it is necessary to spend a certain amount of time to accurately connect the conductive wire with the workpiece to be treated. The frequent execution of this connection operation not only consumes a lot of time and energy of the operator, but also increases the working intensity of the entire production process. In addition, the conductive material and the conductive wire are immersed in the electrolyte solution containing chromium ions for a long time, which has a potential risk. The metal conductive wire may undergo oxidation-reduction reaction with chromium ions in the solution, which will accelerate the corrosion rate of the conductive wire material. This corrosion phenomenon not only shortens the service life of the conductive wire and the conductive material, but also affects the stability of the electrolyte solution, thereby reducing the efficiency and safety of the entire chromium plating process.
