Technical field
The utility model belongs to Electrolyzed Processing field more particularly to a kind of mask Electrolyzed Processing for magnetic-adsorption cathode
Device.
Background technology
Mask Electrolyzed Processing is a kind of to be attached with the electrical isolation screened film containing a large amount of hollow out figure structures in workpiece anode
（That is mask）Special shape electrochemical machining method.It can single-sided process be also two-sided processes simultaneously.When processing, workpiece anode
The region by mask pattern shielding is not removed by the dissolving of selectivity, to the numerous and different group of disposable forming quantity
Hole or group's pore structure.Therefore, mask Electrolyzed Processing has much process advantage in metal micro structure array manufacture view.Existing mask
Electrolyzed Processing has electrolytic transfer processing, movable mask Electrolyzed Processing, interpolar filling porosity mask Electrolyzed Processing and foam cathode
Mask Electrolyzed Processing etc..Movable mask Electrolyzed Processing mask reusable, using it is flexible the features such as, quite paid attention in recent years.However,
Movable mask Electrolyzed Processing is required for greatly being compressed movable mask by means of mechanical force at present, therefore dress all must specifically be clamped
It sets, and the use of clamping device inevitably passes in and out pole clearance, the discharge of electrolysate and uniform flow field to electrolyte
Structure bring certain negative effect, and increase process costs and operation difficulty.In addition, existing mask electrochemical Machining Technology
The supply of interpolar electrolyte（Mainly there are the feed liquid ways such as orthoflow fliud flushing, reflux formula fliud flushing and lateral flow type fliud flushing）It is essentially all
It is realized by pumping mode.This feed liquid way is substantially stationary in the fluid pathways that interpolar is excited, and with apparent side
Tropism and current gradient feature.These are also usually the non-uniform one of the main reasons of mask Electrolyzed Processing structure size.
For this reason, it is necessary to develop new mask electrochemical machining method, to further increase mask Electrolyzed Processing precision and can
It is realisation.
Invention content
The purpose of this utility model is to provide a kind of magnetic force suction without mechanical apparatus pressing activity mask, without pumping feed flow
The mask electrolytic machining device of attached cathode.
In order to achieve the above objectives, the technical solution of the utility model is：A kind of mask for magnetic-adsorption cathode is electrolysed
Processing unit (plant), including electrolyte, electrolyte circulating filtration unit, electrolytic cell, power supply and by successively successively sequence be closely superimposed upon
Workpiece anode, mask and magnetic conduction foam metal together, it is characterised in that：It further includes periodic reverse translation driving unit, outside
Surface is coated with the permanent magnets and hanging rod of acid-alkali-corrosive-resisting material；The permanent magnets are fixed on the lower end of hanging rod；The extension
Bar and periodic reverse translation driving unit are hinged and can make the period and commutate clockwise or counterclockwise translation；The permanent magnets, work
Part anode, mask and magnetic conduction foam metal are combined and are totally submerged in electrolyte always；The workpiece anode is solid
Due in permanent magnets.
The translational motion track of the hanging rod is circle.
The electrolyte is placed in electrolytic cell.
The electrolyte circulating filtration unit is installed on electrolytic cell.

The workpiece anode and magnetic conduction foam metal is connected with the anode and cathode of power supply respectively.
Device operation principle described in the utility model is as follows.
Workpiece anode, mask and magnetic conduction foam metal are closely superimposed together and form process and assemble with permanent magnets successively
Body.The magnetic line of force of permanent magnets reaches magnetic conduction foam metal after penetrating workpiece anode, mask, is convenient for magnetic conduction foam metal and permanent magnets
Between formed magnetic effect, in this way, the mask and workpiece that are placed between magnetic conduction foam metal and permanent magnets are just in their magnetic
It is mutually overlayed together under effect.Workpiece anode and magnetic conduction foam metal are connected with the anode and cathode of power supply respectively, permanent magnetism
Block is fixed on the lower end of hanging rod, and hanging rod is hinged with periodic reverse translation driving unit and can make the period and commutates clockwise or counterclockwise
Translation.Under the action of periodic reverse is translatable driving unit, hanging rod drives the process and assemble body being entirely placed in electrolyte to do week
Phase commutation translation and track is circle, the electrolyte in electrolytic cell in the interaction process of process and assemble body from magnetic conduction foam
Enter processing gap in a large amount of gaps of metal and participates in electrochemical reaction, and electrolysate is equally because of interaction between the two
And processing gap is discharged from the gap of magnetic conduction foam metal.Because magnetic conduction foam metal gap is in spatial distribution, in addition translation side
It repeats to replace to the period, so electrolyte can be made to pass in and out, the channel being discharged to product is numerous, flow direction is random and flow field is variable, thus
Workpiece is promoted relatively evenly to dissolve.The material polypropylene of hanging rod has acid-alkali-corrosive-resisting, can be used for a long time and reduce cost
Feature.This device is easy to operate, is easily achieved, high precision machining.
The utility model has the advantages that：
1, mask is easy to attaching and uniform force, is not necessarily to additional clamping device.Pass through mechanical force with some（It is all required specific
Clamping device）It is compared to overlay mask, magnetic force has the spies such as be easily achieved, force effect distribution is continuous in terms of fixed object
Point, and exclude to influence on the disengaging of electrolyte and electrolysate smaller, the structure in flow field is more uniform, more favorably obtain uniformity compared with
Good micro structure array.
2, the flow direction of electrolyte differs, and electrolysate is easy to be discharged, machining accuracy higher.Due to permanent magnets, workpiece anode,
Mask and magnetic conduction foam metal（Form process and assemble body）The translational motion of periodic reverse is done in the electrolytic solution, and electrolyte flow direction is more
Sample, gradient are random so that Flow Field Distribution is more uniform, to obtain the more uniform processing dimension of distribution, machining accuracy higher.
