Description
Technical field
The invention belongs to Electrolyzed Processing field, more particularly to a kind of for interpolar porous media filled-type mask Electrolyzed Processing
Draw liquid device.
Background technology
The rational Surface Texture such as micro-pit array, micro groove array can effectively reduce friction and wear, improve device table
Face radiating and fluid motion state, are widely used.The main method of processing micro-pit array has Laser Processing, precision optical machinery to add at present
Work, spark machined and Electrolyzed Processing.Wherein Electrolyzed Processing is because be not directly contacted with instrument in process and workpiece, no
The advantages of tool electrode loss, high in machining efficiency, surface of the work will not produce machining stress, deformation and heat affected area, is a kind of
The important means of micro-pit array is obtained in metal surface.Mostly general Electrolyzed Processing is to coat one layer of photoresist in surface of the work
Afterwards, carry out photoetching, be electrolysed, removing photoresist obtains micro-pit array.The method complex process, efficiency are low, high cost.Although negative electrode is prepared and is covered
Modulus method and liquid photoresist is replaced to do the appearance of the mask electrochemical machining method such as mask with dry film photoresist, can be to a certain extent
Solve the above problems.But mask is to realize the premise that high accuracy micro-structural is processed with fitting tightly for workpiece, and traditional mask is pasted
It is the means by pressurizeing mostly coating method, needs special lamination or film sticking equipment, and application difficult on complicated surface.

And two boss 3-6 formed between adjacent grooves；Groove includes the remittance liquid bath 3-5 of the circle positioned at 3 center of negative electrode, is located at except remittance
The drainage trough 3-3 of equally distributed arcuation in windmill in liquid bath 3-5 other regions outer and install in two adjacent drainage troughs it
Between liquid outlet groove 3-1；Drainage trough 3-3 and liquid outlet groove 3-1 not insertion；Drainage trough 3-3 one end is connected with remittance liquid bath 3-5, the other end
Closing and close 3 outer of negative electrode；Liquid outlet groove 3-1 one end is provided with the outlet positioned at the most outer of negative electrode 3, other end closing and close remittance
Liquid bath 3-5；Through hole on negative electrode 3 includes that inlet opening 3-4 and fluid hole 3-2, inlet opening 3-4 are distributed in remittance liquid bath 3-5 and drainage
In groove 3-3, fluid hole 3-2 is distributed in liquid outlet groove 3-1；Top cover 1, sealing gasket 2, negative electrode 3,4 and of nonmetal flexible porous media
Mask 5 is fitted tightly from top to bottom successively on workpiece anode 6；The front of negative electrode 3 is pasted with nonmetal flexible porous media 4
Close.
The material of negative electrode 3 is metal, and thickness is 2mm.
Boss 3-6's is highly identical.
A diameter of 0.2mm of a diameter of 0.5mm of inlet opening 3-4, fluid hole 3-2, between the geometric center of adjacent holes
Away from for 1.5mm.
Remittance liquid bath 3-5, the deep equality of drainage trough 3-3 and liquid outlet groove 3-1, are 0.5mm, and remittance liquid bath 3-5's is a diameter of
The width of 15mm, drainage trough 3-3 is 0.8mm for the width of 0.5mm, liquid outlet groove 3-1.
The number of drainage trough 3-3 is 24, and the number of liquid outlet groove 3-1 is 24.
The material of sealing gasket 2 is the electric insulation resilient nonmetallic material such as silicon rubber, EP rubbers, polytetrafluoroethylene (PTFE), thickness
For 1mm.
Sealing gasket 2 can be completely covered drainage trough 3-3 and liquid outlet groove 3-1.
The geometric center of 7 three of inlet on the central through hole 8 on sealing gasket 2, remittance liquid bath 3-5, top cover 1 overlaps.

Inlet opening 3-4 enter in nonmetal flexible porous media 4.As the mesh in nonmetal flexible porous media 4 intermeshes
Insertion, so electrolysis liquid energy is circulated in nonmetal flexible porous media 4.As the inlet opening 3-4 gross area on negative electrode 3 is more than
On the one hand the fluid hole 3-2 gross area, so electrolyte is via neighbouring with inlet opening 3-4 fluid hole 3-2 on negative electrode 3 and nonmetallic
The side of flexible, porous medium 4 is expelled directly out, and on the other hand reaches workpiece anode 6 by the mask micropore on mask 5.Due to entering
Fluid apertures 3-4 is distributed than more uniform on negative electrode, therefore reaches the Flow Field Distribution on 6 surface of workpiece anode evenly.And electrolysate
Then nonmetal flexible porous media 4 is entered from micro- hole of workpiece anode 6.Subsequently, the electrolysate near 3 outer of negative electrode is by non-
Area to be machined is discharged in the side of metal flexible porous media 4, and the electrolysate away from 3 outer of negative electrode is directly by facing on negative electrode 3
Near fluid hole 3-2 discharges area to be machined.The circulation style of this kind of electrolyte is beneficial to the circulation of electrolyte and electrolysate
Discharge, so as to improve the uniformity of surface to be machined Flow Field Distribution, and then the effect of raising Electrolyzed Processing and speed, especially suitable
In the large-area workpiece of processing.
