Abstract
A technology for manufacturing chain features that the surface of its all parts are chemically nickeled after removing rust and oil, and its steps are as follows: workpieces, removing rust, removing oil, washing, activating, washing, preheating, chemical nickeling by immersing them in nickel-plating solution, washing, drying, and heat treating. Its advantages are high hardness and antiwear-anticorrosion nature, and compact and smooth surface.
Description
The present invention relates to a kind of manufacture method of chain, relate in particular to chain surface-treated method.
At present, both at home and abroad the chain industry mainly reaches with the method for electronickelling or electrogalvanizing and uses preferably effect, also useful stainless steel chain, and the former is short, not wear-resisting service life, and latter's cost is high, tensile strength is low and it is complicated to produce assembly technology. Below all can not satisfy user's instructions for use. Traditional handicraft---common precision roller chain performance and technique are as follows: chain is connected by carrier bar, bearing pin, roller, sleeve and consists of. Wherein, the manufacturing process of carrier bar comprise punching out, heat treatment, polishing, surface send out blue, oil antirust. The manufacturing process of bearing pin comprises blanking, cylindrical grinding, heat treatment, polishing, antirust processing. The manufacturing process of roller comprises cold pier, heat treatment, polishing, antirust processing. The manufacturing process of sleeve comprise roll, heat treatment, polish, oil antirust. Each parts that above-mentioned processes is good assemble again.
The object of the present invention is to provide a kind of manufacture method of non-maintaining chain, especially chain surface-treated method. Chain according to the method manufacturing has the characteristic of high-strength, high-anti-friction and can reduce frequency of maintenance, reduces maintenance cost.
For achieving the above object, the present invention has adopted following technical scheme: a kind of manufacture method of chain, and the carrier bar, bearing pin, roller, the sleeve that consist of chain are processed by following processing step respectively: (1) is shaped; (2) heat treatment; (3) polishing; (4) surface treatment, (5) assemble above-mentioned each parts, it is characterized in that described process of surface treatment is the chemical nickel plating treatment process, the steps include: a. workpiece; B. rust cleaning; C. oil removing; D. clean; E. activation; F. clean; G. preheating; H. soak in the chemical nickel-plating solution; I. clean; J. dry; K. heat treatment.
Described chemical nickel-plating solution is formulated by 2: 2: 1 mass ratioes by nickelous sulfate, inferior sodium phosphate, sodium acetate, compound method is after nickelous sulfate, inferior sodium phosphate, sodium acetate are dissolved respectively fully, add successively and do quiet coating bath, then add additive, and add water and fully stir, the heating tank liquor is adjusted tank liquor pH value to 4.8 with glacial acetic acid, the operating temperature of chemical nickel-plating solution is 80-90 ℃, and the plating amount is 0.5-2dm2/L。
Owing to adopted technique scheme, each building block of chain has high rigidity and high-wearing feature, and under sedimentation state, coating hardness is HV500-550 (HRC49-55). Hardness is HV900-1000 (HRC69-72) after 400 ℃ of processing. Test shows in dry and lubricated situation, all to have the wearability that is equivalent to hard chrome. Have excellent resistance of corrosion, chemical nickel plating spare has good corrosion stability in salt, alkali, ammonia and seawater. Few, fine and close, any surface finish of chemical nickel plating chemical deposition Ni-P alloy layer hole. Chemical nickel plating is processed superior self lubricity. The nickel chemical plating technology environmentally safe can replace hard chrome plating. The product itself that nickel chemical plating technology is made is pollution-free, and product in use can not produce pollutant. Be applied to the nickel chemical plating technology performance introduction of chain part:
The whole chain performance of chemical nickel plating chain and common precision roller chain is compared as follows table:
