Description
Technical field
This utility model relates to field of electroplating, particularly relates to a kind of plating cathode fixture.
Background technology
At present, the method that conventional chrome-plating process typically uses rack plating, electroplate using part as cathode conductor,
But, for the local chromium plating of small entity part, it is impossible to use the method for rack plating to produce in enormous quantities,
It need to be according to the shape of part, fixing requirement and electric means configuration Special cathode plate, in chrome-plating process,
Minus plate have to stand the corrosion of reverse current corrosion+Cr-plating Bath, and existing producer is all to use titanium gold,platinized
Minus plate electroplate, but owing to the local chromium plating of small entity part generally uses magnetic-adsorption to fix,
Magnetic conductivity and electric conductivity to minus plate have certain requirement, and titanium does not have good magnetic conductivity, and
Plated surface platinum is expensive, and service life is short, cost is high；Therefore, titanium alloy is being used to do magnetic-adsorption
During negative electrode, need the strict thickness controlling titanium plate, and the processing of titanium plate is abnormal difficult, is processed into the titanium plate of thin plate
Surface smoothness does not reaches technological requirement, often occurs minus plate to deform in process of production due to insufficient strength,
Thus cause electroplating quality unstable, thus, it is badly in need of solving.
Utility model content
The purpose of this utility model is for the problems referred to above, it is provided that a kind of plating cathode fixture, to solve
The minus plate of existing plating negative electrode uses titanium gold,platinized, and magnetic conductivity is poor, and surface smoothness is low, yielding,
The problem affecting electroplating quality.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of plating cathode fixture, including minus plate, described minus plate is made up of iron-nickel alloy material, its
Thickness is 8～12mm, and the bottom of minus plate is provided with Magnet module, and the top correspondence workpiece of minus plate is fixed
Position has notch, and the width of described notch is less than the width of workpiece.
As a kind of preferred version of the present utility model, the surface configuration of described minus plate has platinum layer；Effectively
Improve its corrosion resistance.
As a kind of preferred version of the present utility model, the thickness of described platinum layer is 4～6um.
As a kind of preferred version of the present utility model, the thickness of described platinum layer is 5um.
As a kind of preferred version of the present utility model, the thickness of described minus plate is 10mm；
The beneficial effects of the utility model are, the minus plate of described plating cathode fixture uses iron-nickel alloy,
Having good electric conductivity, magnetic conductivity and corrosion resistance, and good processability, surface smoothness is high, effectively
Improve electroplating quality, additionally, by arranging notch, both ensured the discharge of hydrogen in electroplating process, and
Do not take off the magnetic cleaning to workpiece back under pipeline state, there is again correction magnetic line of force direction, regulation magnetic force big
Little effect, simple in construction, is easily achieved.

Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
It is understood that embodiment described herein is used only for explaining this utility model, rather than to this practicality
Novel restriction.
Refer to shown in Fig. 1, Fig. 1 is the structural representation of this utility model plating cathode fixture.
In the present embodiment, a kind of plating cathode fixture, including minus plate 1, described minus plate 1 is by ferrum nickel
Alloy material is made, and its thickness is 10mm, and the bottom of minus plate 1 is provided with Magnet module 2, and minus plate 1
Correspondence workpiece 3 fixed position, top at have notch 4, the width of described notch 4 less than the width of workpiece 3,
The surface configuration of described minus plate 1 has platinum layer, the thickness of described platinum layer to be 5um.
Although it is noted that in the present embodiment, the thickness of platinum layer is 5um, but this utility model is not
Being limited to this, the thickness of platinum layer can also be 4um or 6um or any value between 4～6um, 5um
For combining the preferred version after cost.
Although it is noted that in the present embodiment, the thickness of minus plate 1 is 10mm, but this practicality is new
Type is not limited to this, and the thickness of minus plate 1 also can be 8mm or 12mm or the arbitrary number between 8～12mm
Value, 10mm is the preferred version after combining cost.
Above-mentioned a kind of plating uses iron-nickel alloy with the minus plate 1 of cathode fixture, and it can have with titanium gold,platinized
Identical connects electricity reliability, and the slightest galvano-cautery also only occurs during long-time plating anti-carves,
And can keep stable for a long time at the contact resistance with workpiece 3 contact portion, make extensive high request
Closely selective electroplating is possibly realized, and has reached design requirement on the whole；Meanwhile, due to minus plate 1
Thickness reaches 10mm, improves minus plate 1 precision and reduces surface roughness, change in use
Shape is less, improves the product stability plated out；Meanwhile, the minus plate 1 that iron-nickel alloy material is made is permissible
Remove surface galvano-cautery layer by processing, to reach the effect repeatedly used, be substantially reduced minus plate 1
Use cost, reliability is greatly improved simultaneously；Furthermore, it is possible on minus plate 1 plated surface platinum
Gold so that it is have identical corrosion resistance with titanium gold,platinized minus plate.
Above example simply elaborates ultimate principle of the present utility model and characteristic, and this utility model is not by upper
Stating embodiment to limit, on the premise of without departing from this utility model spirit and scope, this utility model also has each
Plant change and change, in the range of these changes and change both fall within claimed this utility model.This practicality
Novel claimed scope is defined by the following claims.
