Comprehensive pretreatment system for metal hard chromium electroplating

Abstract

The comprehensive pretreatment system comprises a support, a cleaning pool and a spraying mechanism and further comprises a rotary rolling mechanism and a cleaning mechanism, the support comprises a top plate, a bottom plate and two side plates, the top plate and the bottom plate are arranged in parallel, and the two side plates are vertically arranged between the top plate and the bottom plate and distributed in a bilateral symmetry mode; the upper end and the lower end of each side plate are fixedly connected with the top plate and the bottom plate respectively, the cleaning pool is fixedly arranged on the upper side of the bottom plate, and the rotary rolling mechanism is arranged between the two side plates and located above the cleaning pool. The lower end of the air cylinder is provided with an elastic mechanism and connected with a strip-shaped plate in the cleaning mechanism through the elastic mechanism.

Description

technical field [0001] The present application belongs to the technical field of electroplating treatment, for example, a comprehensive pretreatment system for metal hard chrome 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. Improve wear resistance, electrical conductivity, reflectivity, corrosion resistance and enhance the appearance, etc. The outer layer of many coins is also electroplated. [0003] When performing hard chrome plating on shaft parts, it is generally necessary to pretreat the parts, such as cleaning the shaft parts. Cleaning in the cleaning pool can only clean off the dust and dirt on the surface, but when some rust or stains with strong adhesion are produced on the ...

Problems solved by technology

[0003] When hard chrome plating is performed on shaft parts, it is generally necessary to pretreat the parts, such as cleaning the shaft parts. In related technologies, when cleaning the shaft parts, the shaft parts are generally directly put into the Cleaning in the cleaning pool can only clean off the dust and grime on the surface, but when some rust or stains are firmly bonded on the surface of the part, it is difficult to clean it, which will affect the effect of subsequent hard chrome plating
