Description

Electrolytic buffing attachment
Technical field
The invention belongs to the metal surface treating apparatus technical field, relate to a kind of metal works curved surfaces electrolytic buffing attachment.
Background technology
Electropolishing is a kind of surface of workpiece to be carried out method for finishing manufactured, and the method is that metal works is placed in the electrolytic polishing trough that electrolytic polishing liquid is housed, and electrolysis is carried out in energising to electrolytic polishing liquid.Carrying out along with electrolysis, form the larger liquid film of viscosity at surface of workpiece, thickness of liquid film skewness on the rough surface of metal works, the lip-deep liquid film of bossing is thin, and the lip-deep liquid film of rest part is thick, therefore resistance is not identical everywhere for anode surface.Metal works bossing resistance is little, and current density is larger, makes bossing faster than the recessed part dissolving.Therefore, it is level and smooth bright that hackly surface of workpiece becomes, and reaches the effect of polishing.
But electropolishing has its limitation.The first, the negative electrode of electrolytic buffing attachment is generally stainless steel flat plate or plumbous dull and stereotyped, and electropolishing requires to have certain uniform distance between metal works finished surface and the negative electrode.Therefore, present electrolytic buffing attachment can only be used for the processing on metal works plane usually.The second, in the electropolishing process, can produce amount of heat, be not easy quick dissipation, heat easily affects workpiece surface quality; And can reduce concentration of electrolyte in the electrolytic process, be unfavorable for production requirement efficient, stable, that continue.Patent (200620044173.4) discloses a kind of electropolishing corrosion tester.Adopt magnetic agitation promoting flowing of electrolytic solution, yet magnetic agitation can only realize the Uniform Flow of horizontal direction, vertical direction is difficult to convection current and mixes, and the anode surface that especially is difficult to be opposite to the electrolytic solution the top forms effective convection current.Patent (102168298A) discloses a kind of use for laboratory metallographic sample electrolyzing and corroding device and electrolytic corrosion method, and cathode electrolytic cell and electrolytic solution storage tanks bottom are communicated with, and promote the height that the pressure transfusion cork can be regulated electrolytic solution in the cathode electrolytic cell.Yet adopt the structure of pressure transfusion cork to be only applicable to the laboratory scientific research, and can not satisfy the requirement of suitability for industrialized production.
Therefore, be necessary to research and develop a kind of with low cost, easy and simple to handle, good reproducibility for the defective of prior art and device existence, easily promote the practical electrolytic buffing attachment that is applicable to the metal works curved surfaces.
Summary of the invention
The object of the invention is to provide a kind of with low cost, easy and simple to handle, good reproducibility, the electrolytic buffing attachment that is applicable to the metal works curved surfaces of easily promoting.Technical scheme of the present invention is: join the arc negative electrode by cathode electrolytic cell, electrolytic solution storage tanks, rinse bath, acid proof pump, communicating pipe, negative plate and reality and form, cathode electrolytic cell is communicated with communicating pipe with the electrolytic solution storage tanks, acid proof pump is equipped with in the connecting pipeline mid-way of upper end, negative plate connects power cathode, and place bottom the cathode electrolytic cell, join arc cathode bottom and negative plate close contact in fact, bottom of rinse bath is equipped with impeller.
Join in fact the shaped upper part of arc negative electrode, join and be processed into radius greater than the deep-slotted chip breaker of workpiece curved surfaces.During polishing, polished workpiece is communicated with positive source, immerses to fill in the cathode electrolytic cell of capacity electrolytic polishing liquid.Simultaneously, the electrolytic solution storage tanks also fills the electrolytic polishing liquid of capacity.Join in fact arc cathode bottom and negative plate close contact, be communicated with power cathode; Keep the real arc negative electrode top deep-slotted chip breaker of joining with the polished curved surfaces of workpiece certain distance to be arranged all around.Adopt certain voltage and certain electric current, breaking circuits behind the electropolishing certain hour.After hanging the taking-up metal works, immerse the rinse bath that fills capacity scavenging solution (alcohol), start the pulsator apparatus in the groove, the impeller rotation can drive groove cleaning liquid inside formation eddy current, scrubs workpiece arc glazed surface.After cleaning certain hour, taking-up, dry, check.After the polishing, metal works hemisphere surface roughness can reach Ra0.01-0.05 μ m.
Polishing workpiece repeatedly after, open acid proof pump, because cathode electrolytic cell and electrolytic solution storage tanks were communicated with two communicating pipe, adopt acid proof pump to drive electrolytic solution, electrolytic polishing liquid stereo circulating in two grooves be can make, the temperature of electrolytic polishing liquid in the cathode electrolytic cell and stablizing of concentration kept.According to the production process monitoring, carry out the 20s circulation of elecrolyte one time behind per 30 electropolishings, temperature rise is only 1-3 ℃ in the cathode electrolytic cell.
The present invention has following beneficial effect:
1, the present invention compared with prior art can satisfy the electropolishing requirement of metal works curved surfaces, has widened the practical ranges of electropolishing technology.
2, the present invention adopts the form that is communicated with cathode electrolytic cell and electrolytic solution storage tanks with communicating pipe, drive electrolytic solution with acid proof pump, make the electrolytic polishing liquid stereo circulating, keep the temperature of electrolytic polishing liquid in the groove and stablizing of concentration, reduce and produce the intermittent time, raise the efficiency.
3, bottom of rinse bath of the present invention is equipped with impeller, and the impeller rotation can drive the groove cleaning liquid inside and form eddy current during use, scrubs workpiece arc glazed surface, can strengthen cleaning performance, improves cleaning efficiency.
4, because electropolishing and electrolytic corrosion principle communicate, the present invention can be used for reference by other electrolytic corrosion equipment.
