Problems solved by technology

[0003] The existing electroplating process has different electroplating methods for plating various metals. In order to make the electroplating layer on the surface of the electroplated workpiece meet the specified standards, many technicians have devoted their research direction to the electroplating solution and the electroplating process. The main body of the electroplating equipment, a set of suitable electroplating equipment and electroplating process can make the electroplating effect better, especially when electroplating metals such as chromium and nickel, and the shape of the electroplating workpiece is similar to that of a sleeve. The general electroplating process and electroplating equipment cannot meet the requirements

Abstract

The invention relates to an electroplating process. The electroplating process mainly comprises the following steps of carrying out pre-electroplating treatment, carrying out nickel electroplating, carrying out recovery, carrying out chromium electroplating and carrying out after-electroplating treatment. Electroplating equipment special for the electroplating process is combined, wherein the electroplating equipment comprises a hanging rack head and an electroplating hanging rack; the hanging rack head comprises a supporting arm capable of supplying power and a hanging plate assembly connected with the supporting arm, the hanging plate assembly comprises a conductor hanging plate and a connecting part, and the connecting part is further connected with an auxiliary hanging plate which is arranged in parallel with the conductor hanging plate; and the electroplating hanging rack comprises a main hanging rack and an auxiliary hanging rack, the two sides of the main hanging rack are provided with bearing frame bodies which can be used for containing to-be-electroplated workpieces at intervals respectively, and auxiliary conductors are arranged on the positions, corresponding to the bearing frame bodies, of the auxiliary hanging rack. The special electroplating equipment is matched with the special electroplating process, and therefore electric potential of the inner surfaces of theelectroplated workpieces can be enhanced during the electroplating process, and electroplated layers on the inner surfaces of the electroplated workpieces can be attached to the inner surfaces and uniform; and the electroplating equipment can be applied to the electroplated workpieces of any shape, so that the application range of the equipment is expanded.

Description

technical field [0001] The invention relates to the technical field of electroplating technology and electroplating equipment, in particular to an electroplating technology and electroplating equipment. Background technique [0002] Electroplating is the process of plating a layer of other metals or alloys on the metal surface using electrolysis principles, using electrolysis to attach a layer of film to the metal surface, thereby preventing metal oxidation, improving wear resistance, conductivity, light reflection, and corrosion resistance sex and enhance the aesthetic effect. [0003] The existing electroplating process has different electroplating methods for plating various metals. In order to make the electroplating layer on the surface of the electroplated workpiece meet the specified standards, many technicians have devoted their research direction to the electroplating solution and the electroplating process. The main body of the electroplating equipment, a set of s...
