Description
Technical field
The present invention relates to a kind of manufacture method of chain.
Background technology
At present, in the complete processing of chain, be that carrier bar, bearing pin, roller, the sleeve that will constitute chain handled by following processing step respectively substantially: shaping, thermal treatment, polishing, surface treatment, above-mentioned each parts are assembled.The process of surface treatment of each part of chain wherein, promptly anticorrosion, anti-corrosive technology are difficult problems always.The chain industry mainly reaches antirust purpose with surperficial blueing process both at home and abroad, but realizes owing to a surface orchid forms ferriferrous oxide film by the oxidation principle, and unstable properties is perishable.In addition, sending out treatment temp blue is 300-340 ℃, and the time is 15-25 minute, and the mechanical propertys such as tensile strength of this Temperature Treatment rear chain all will be affected, and can not be applied to bearing pin, sleeve and roller, can only use on carrier bar.Because variation of temperature is sent out blue part and can be produced the color and luster inequality, scrap rate is higher.And the Sodium Nitrite of sending out blue employing is environmentally harmful chemical.
Summary of the invention
The object of the present invention is to provide the manufacture method of the chain that a kind of corrosion-proof wear is more superior, yield rate is high, the environment for use of this method is more stable, can be applicable in the process of surface treatment of each parts such as carrier bar, bearing pin, sleeve and roller.
For achieving the above object, the present invention has adopted following technical scheme: a kind of manufacture method of chain, the carrier bar, bearing pin, roller, the sleeve that constitute chain are handled by following processing step respectively: shaping, thermal treatment, polishing, surface treatment, above-mentioned each parts are assembled, it is characterized in that the step of described process of surface treatment is: a. degreasing, b. washing, c. table accent, d. surface blackening, e. wash, the f. clear water is washed, g. saponification, h. are dewatered, i. oils, the j. de-oiling.
The sodium carbonate solution degreasing is adopted in described degreasing, and wherein the content of yellow soda ash is 3-5%, and the content of water is 95-97%, and the temperature of solution is 60-100 ℃, and pH value is 11-14, and the time that part soaks in solution is 5-10 minute.
Described washing is part to be placed in the tap water roll, and water requires overflow, and the time is 1-2 minute.
It is that part is immersed in the titanium phosphate salts solution that described table is transferred, and the content of phosphoric acid titanium salt is 0.2-0.3% in the titanium phosphate salts solution, and the content of water is 99.7-99.8%, and soak time is 1-2 minute, and the pH value of solution is 8-9.
Described surface blackening technology is that part is immersed in the following solution, this solution is joined zinc nitrate 124 grams by every kg water, the ratio of primary zinc phosphate 20 grams and Sodium Fluoride 1 gram is formulated, solution acidity is 60 ± 5 points, iron divides content to be: 2-4g/L, solution temperature is at 85-90 ℃, and soak time is 10-20 minute.
Described washing is that part is rolled in tap water, and the time is 1-2 minute.
It is to roll in the tap water in groove that described clear water is washed, and requires overflow, and the time is 1-2 minute.
Described saponification is that part is immersed in the following solution, and this solution is pressed saponified oil 10-15%, the ratio preparation of water 85-90%, and solution temperature is 100 ℃, soak time is 2-3 minute.
Described oiling is that part is immersed in the following solution, and this solution is pressed 70% No. 15 machine oil, the ratio preparation of 30% No. 901 slushing oil, and solution temperature is 100-110 ℃, soak time is 2-3 minute.
Owing to adopted technique scheme, chain according to art breading of the present invention, form a solidity to corrosion epithelium on its surface, greatly improve the product corrosion resisting property, through assay (by international 3% copper-bath corrosion test standard), solidity to corrosion according to the chain of art breading of the present invention can surpass 20 minutes, and after common tight Chain Plank of Roller Chain surface sends out blue the processing, just begins to be corroded after 60 seconds.In addition, above-mentioned solidity to corrosion epithelium can prevent to rotate, the contact between the sliding part surface metal, phenomenon such as therefore sintering can not take place, bite, and simultaneously, the epithelium oil absorbency of piece surface is good, so the surface lubrication raising.The initial stage that re-uses just can be avoided the chain drive wearing and tearing, can guarantee antirust efficiently anti-corrosion performance simultaneously, has so just greatly prolonged the work-ing life of chain product to a certain extent.Slight revolution mark in the time of can also removing mechanical workout by the blackout processing.Process of surface treatment of the present invention and traditional technology and performance are compared as follows table:
