Description
Technical field
The utility model is related to ultrahigh strength steel part blind hole and repairs field, and more specifically it is part blind hole nickel plating
Solution agitating device in journey.
Background technology
Undercarriage ultrahigh strength steel part is in use due to for a long time by mechanical shock and abrasion, stress corrosion etc.
There is the phenomenon of overheat and corrosion in situation, local matrix, be typically mainly distributed at sealing cooperation and piston like motion stress
Concentrated area, such as bushing mounting holes, inner cylinder endoporus obturage mating surface, are required according to the servicing manual of parts, these defects
It must be completely removed, then size is repaired by electroplating technology, and electronickelling is primarily adapted for use in the reparation of thicker size, it is high to ensure
The quality safety of strength steel, generally uses sulfamate electronickelling to obtain the coating of low stress.
There is pin hole on nickel coating is most incident defect during nickel plating by amino sulphonate, especially for for a long time
Plating, it is difficult to avoid；So-called pin hole, is the pore that visually can directly be seen that, can be divided into three types according to feature：
One, matrix deficiencies
Such pin hole is non-circular shrinkage pool, is mostly because metal base surface has micropore, pit, corrosion and surface
Field trash is formed；
Two, gas evolution types
The shape of pin hole is similar " tadpole ", be due to part in electroplating process as negative electrode, and cathode surface separates out hydrogen
Gas, when wetting agent is inadequate, the tension force of solution becomes big, the adhesion strength of bubble becomes strong, and hydrogen is because of the buoyancy by itself, solution
Stirring (being typically all upward air stirring) is floated up, but can not be shaken off, and forms pin hole, this kind of pin hole is entirely being electroplated
Area distribution is more uniform；
Three, gas detention types
Pin hole is larger, generally local distribution, mostly because parts locally oil removing is not thorough enough, or because some solids suspend
Thing is adsorbed on surface, causes the region hydrophobic, the gas of generation is easily detained generation pin hole；
For pin hole Producing reason, in addition to above description, also several factors：Such as plate front activating state and nickel plating is molten
Metal impurities, pH value in liquid, current density, chemical composition, as long as not controlled on one side wherein having, pin hole will be produced
It is raw, and for high-duty steel part obturage face for, a pin hole does not allow to exist.
Because the delay of bubble is the common cause of generation pin hole, traditional electro-nickel process and modern relatively advanced electricity
Nickel plating technology is required to be reduced or avoided using two ways：One, air or mechanical agitation solution；Two, negative electrode (drive part)
It is mobile, cause the bubble that piece surface is produced to be difficult to be detained by both modes, but for undercarriage heavy parts, negative electrode is moved
It is dynamic to realize, even if being driven using high power large-size machine, do not reach the travel frequency of requirement, it is impossible to obtain good effect yet
Really, and for deep blind hole region, mechanical agitation (bottom land uses mechanical device agitating solution) is not applied to completely, and air stirring can be with
Operation, but supplement slower because solution solution outside hole is inside in blind hole, the air being passed through can aggravate the office of part inwall on the contrary
The hollow phenomenon in portion, makes more gas residues produce bubble in inwall, while this mode is difficult to stir, especially blind hole
Dynamics is not stirred in depths root substantially, and pin hole can not still be avoided.
The content of the invention
The purpose of this utility model is to provide the solution agitating device in a kind of part blind hole Ni-Speed, simple in construction,

Hydrochlorate nickel plating solution is in inwall quick rotation and rises, and takes away the bubble for being attached to part blind hole inwall, so as to fundamentally solve
Certainly pin hole produced problem；
(2) stainless steel anode is used, dissolving and the deposition of nickel dam with anode, the metallic nickel ions in blind hole region
The quick supplement of reduction, iron ion increase, but nickel plating by amino sulphonate solution ensure that the quality of solution；
(3) for strong-current electroplating, the solution heating in blind hole is very fast, and nickel plating by amino sulphonate solution in time take away by supplement
Enough heats, it is ensured that the temperature homogeneity of solution；
(4) filter continuous service, the nickel plating by amino sulphonate solution of branch pipe shunting continues into stainless steel impressed current anode
It is flowed into inside part blind hole, is flowed out finally by the fluoroplastics fixed anode frock of part upper end, in blind hole again after portion's supplement
Nickel plating by amino sulphonate solution form a kind of spiralling liquid form, it is ensured that nickel plating by amino sulphonate solution purity,
Realize that bubble and suspended contamination are taken away the purpose of part blind hole in time；
(5) the utility model can be used for the nickel plating of all kinds of part blind holes to repair field, especially on undercarriage
The nickel plating reparation of ultrahigh strength steel part, with extensive；The utility model is applicable not only to the plating of part blind hole groove, applies also for cup
Plating (part does not descend groove, and solution i.e. electrodepositable is only filled up in blind hole, reduces shielding workload and hanging security risk, it is adaptable to
Small blind hole plating on big part).
