Description
Technical field
The present invention relates to needle roller (bearing pin) phosphating process applied technical fields, and in particular to a kind of needle roller high temperature phosphorous chemical industry
Skill.
Background technique
When pre-lubrication and rust-proof coating of the bearing to needle roller (bearing pin) require, it is contemplated that with phosphating process to needle roller
(bearing pin) carries out phosphatization, and unmature needle roller (bearing pin) phosphating process currently on the market, can not use for reference reference.Cause
This, it is necessary to study a kind of high temperature phosphorization process of needle roller (bearing pin).
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of needle roller high temperature phosphorization process.
The object of the present invention is achieved by the following technical solutions: this needle roller high temperature phosphorization process, including following
The step of:
Step 1: extracting degreasing agent, water by the deployed solution of 4.5% mass percent concentration, and are heated to 50 ± 5 DEG C,
By needle roller immerse clean, take out needle roller and use hot water injection, removing surface and oil contaminant；
Step 2: it is rinsed needle roller 3 times with tap water, then rinsed with flowing water；
Step 3: taking activator, water, and by the deployed solution of 4.5% mass percent concentration, needle roller is immersed cleaning 30
~40s；
Step 4: the operation of step 2 is repeated；
Step 5: taking phosphating solution, water, in the deployed solution of mass percent ratio of 1:8, and is heated to 95 ± 5 DEG C, will
Needle roller immerses about 5~10min, while needle roller being made to keep active state；
Step 6: dewatering rust preventive oil is soaked after rinsing needle roller with tap water.
Further, the phosphating coat that the needle roller surface is formed is with a thickness of 3-5 μm, and therefore, the needle roller is in fine grinding time control
Diameter dimension processed is 3-5 μm smaller than the size of finished diameter.
The invention has the benefit that can effectively improve the lubrication in needle roller (bearing pin) assembly, Anticorrosion Problems, make to roll
Needle (bearing pin) has preferable lubricity after mounting, reduces friction, enhancing anti-corrosion capability, and be applied in bearing assembly
The scene more demanding to antifriction lubrication, anti-corrosion capability.
Specific embodiment
Below in conjunction with embodiment, the present invention will be described in detail:
Embodiment: this needle roller high temperature phosphorization process, the needle roller controls diameter dimension in fine grinding, than finished diameter
Size is 3-5 μm small, so that diameter dimension of the needle roller after phosphatization meets finished size requirement, includes the following steps:
Step 1: extracting degreasing agent, water by the deployed solution of 4.5% mass percent concentration, and are heated to 50 ± 5 DEG C,
By needle roller (bearing pin) immerse clean, take out needle roller and use hot water injection, removing surface and oil contaminant；
Step 2: it is rinsed needle roller 3 times with tap water, then rinsed with flowing water；
Step 3: taking activator, water, and by the deployed solution of 4.5% mass percent concentration, needle roller is immersed cleaning 30
~40s；
Step 4: the operation of step 2 is repeated；
Step 5: taking phosphating solution, water, in the deployed solution of mass percent ratio of 1:8, and is heated to 95 ± 5 DEG C, will
Needle roller immerses about 5~10min, while needle roller being made to keep active state；It is about 3-5 μ in the phosphatization film thickness that needle roller surface is formed
m。
Step 6: dewatering rust preventive oil is soaked after rinsing needle roller with tap water.
Degreasing agent, activator and the phosphating solution used in the present invention is common raw material, and innovative point is to prepare dense
The combined use of degree and three kinds of concentration；When innovative point also resides in phosphatization, keeps needle roller to keep active state, can will be placed with rolling
The container of needle is rotated by certain speed, is 15-20 revs/min by testing optimal speed.
The present invention is by carrying out high temperature phosphorization processing to the needle roller after fine grinding, so that needle roller surface formation thickness is about
3-5 μm of phosphating coat, effectively enhancing anti-corrosion capability reduce the friction after assembly, are suitably applied in bearing assembly to antifriction
The more demanding scene of lubrication, anti-corrosion capability is applicable in simultaneously for the needle roller (bearing pin) of all size diameter, mainly answers
Needle roller (bearing pin) for GCr15 production.
It is understood that it will be understood by those skilled in the art that being subject to technical solution of the present invention and inventive concept
It all should fall within the scope of protection of the appended claims of the present invention with replacement or change.
