Electroplating barrel

Abstract

The invention relates to an electroplating barrel which comprises an outer barrel and supporting columns, wherein two ends of the outer barrel are opened; the supporting columns are arranged on two sides of the outer barrel; the two ends of the outer barrel are connected with end covers with gears; an inner barrel is connected to the interior of the outer barrel through springs; a spindle is connected onto one end cover; the outer end of the spindle is movably connected with the supporting column; a rotating shaft is arranged above the outer barrel, and is arranged on the supporting columns; the rotating shaft is movably connected with the supporting columns; a driving gear sleeves the rotating shaft, and is arranged above the end covers; the driving gear is meshed with the gear on one end cover; one end of the rotating shaft is connected with a motor; cathode connectors are arranged on the supporting columns; a power supply device is arranged on one supporting column; cathode contact terminals are arranged in the inner barrel; the cathode connectors and the cathode contact terminals are connected through conducting wires; the motor and the cathode connectors are connected with the power source device. Through the adoption of the electroplating barrel provided by the invention, the problems of low electroplating efficiency and non-uniform part electroplating are solved.

Description

technical field [0001] The invention relates to an electroplating drum, which belongs to the technical field of electroplating. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation ( Such as rust), improve wear resistance, electrical conductivity, reflective properties, corrosion resistance (copper sulfate, etc.) and enhance the appearance. The outer layer of many coins is also electroplated. [0003] During electroplating, the plated metal or other insoluble materials are used as the anode, and the workpiece to be plated is used as the cathode, and the cations of the plated metal are reduced on the surface of the workpiece to be plated to form a coating. In order to eliminate the interference of other cat...
