Description
Technical field
The present invention relates to a kind of electroplating systems, and in particular, to chromium-treated plating is electroplated for revolving body workpieces in one kind
System.
Background technique
Chrome plating have it is excellent it is wear-resisting undermine corrosion resistance, although European Union ROHS instruction clear stipulaties motor electronic is set
It is standby to contain Cr VI from 2008, and the country has begun implementation and european union directive matched " Chinese ROHS " meter
It draws, but due in actual industrial product manufacturing, the low cost process technology also pole of alternative chrome plating especially hard chromium
For scarcity, therefore chromium process is electroplated and is still widely used in manufacture field, if steel cold rolling industry is using hard
Frosting treatment and overproof reparation of the chrome plating for roll；Piston ring, cylinder inner wall and piston rod of gas turbine etc. are using hard
Chromium scuff-resistant coating improves service life；Large-scale engineering machinery crane arm is applied using hard chromium as wear-resisting and anti-corrosion protection
Layer is to improve the service life of hydraulic piston, piston cylinder；Large size wears overproof axial workpiece still using plating hard chrome as super
Poor renovation technique.
There are two classes more distinct issues during large revolving body workpiece electrodeposited chromium process implementing, one is along revolution
The problem of body axial length direction and circumferential thickness uniformity controlling, due to large revolving body workpiece, length is greater than 1.5m-
4m or even longer, circumferential diameter are greater than 250mm-600mm, and often there are biggish thickness on the end of workpiece and circumferential direction
Difference needs subsequent grinding, to keep the uniformity of overall dimensions, causes process to increase, cost increase.And have for some
The galvanization coating of textured surfaces, such as texturing chrome-plated workpieces, subsequent grinding process is strictly forbidden, therefore how to improve big
Type workpiece chrome plating uniformity has important engineering significance.
In addition, in electrodeposited chromium process implementing, the Cr VI in exhaust gas, cleaning solution is also to the harm of human body and environment
Problem in the urgent need to address.Being electroplated in chromium process is mainly Cr VI to human body and environmental hazard substance, belongs to and swallows
Property the extremely toxic object of poisonous substance/imbedibility, can by digestion, respiratory tract, skin and mucous membrane invade human body, may cause inherited genetic lack
It falls into, has carcinogenic danger, have lasting risk to environment.
Thickness of coating uniformity is often influenced by anode and cathode spacing distributing homogeneity, especially for large revolving body workpiece,
The existing plating frock clamp that commonly hangs can not ensure thickness of coating uniformity, and the thickness deviation of upper and lower position and circumferential coating is larger,
It cannot achieve the precision control to surface plating structure size.It is filled comprising electroplating bath and with plating such as the frock clamps of work pieces mate
It sets, rationally setting is for ensureing that the stability of electroplating technological parameter stability, continuity and workpiece quality of coating is played to pass
Important role.Publication " optimized temperature field distribution electroplanting device and its electro-plating method,
In ZL201410203254.3 ", describe by designing insoluble tubular anode, control electrolyte flow field, anode and cathode spacing etc.
Realize the design method of workpiece surface homogeneous coating, but for how useless using the stabilization of guarantee anode and cathode relative position, solution
Gas (electrolyte vapors) discharge, automatic cleaning reflux etc. do not provide preferable solution, this outside dimension is fixed not
Dissolubility tubular anode, which exists, to be difficult to dismount, adjusts the disadvantages of not flexible.The purpose of invention is to provide a kind of environment-friendly type
Compact electroplanting device avoids the influence of steam, waste liquid to ambient enviroment and construction personnel, achievees the effect that environmental protection, pass through simultaneously
The uniformity of the solution large revolving body workpiece electrodeposited chromium thickness of coating such as structure designs, electrolyte circulates, rotation electrode is asked
