Description

Technical Field

[0001] The utility model relates to the technical field of cadmium plating, in particular to a precise control device for a cadmium plating production line. Background Art

[0002] Cadmium plating is a method of depositing a layer of cadmium on the surface of steel parts by electrolysis. It is used to prevent corrosion from seawater or salt spray, improve assembly tightness and friction, and increase aesthetics. It is widely used in manufacturing industries such as ship machinery, navigation instruments, meters and fasteners. It is divided into acid cadmium plating method (with cadmium sulfate or cadmium fluoroborate as the main components of the electrolyte) and cyanide cadmium plating method (with nickel cyanide, sodium hydroxide and sodium cyanide as the main components of the electrolyte). The cyanide cadmium plating electrolyte is simple to prepare and has a high distribution capacity. It can be used to plate parts with complex shapes. The cadmium plating layer has fine crystals and strong bonding force, and is widely used. The cyanide-free electrolyte currently used uses neutral ammonium salts and aminocarboxylic acid complexing agents-ammonium salts. After electroplating, it is passivated in a chromic acid solution, and then rinsed and dried.

[0003] The stirring and circulation system in the existing production line plays a very important role in the cadmium plating production line. The cadmium liquid is stirred by mechanical stirring or gas stirring. However, when the existing stirring device stirs the cadmium liquid, the cadmium liquid is very easy to adhere to the inner wall of the stirring barrel, which easily leads to waste of cadmium liquid. At the same time, when the parts to be processed are transported, the parts will shift during the transportation process due to motor vibration or the influence of external personnel, resulting in the position of the parts under the electroplating nozzle being offset from the electroplating nozzle, affecting the electroplating of the parts. Therefore, it is necessary to redesign the precise control device of the cadmium plating production line to address the above problems. Utility Model Content
