Description
Technical field
The invention belongs to Electrolyzed Processing equipment field more particularly to a kind of devices for cylindrical surface exposure mask Electrolyzed Processing.
Background technique
Micro-pit array is prepared on the metal surface is conducive to the mass-and heat-transfer for reducing the secondary coefficient of friction of friction, improving product
Efficiency, change product surface wetting characteristics and obtain certain particular optical or visual effect.The main of micro-pit array adds at present
Work method has machining, laser processing, electrical discharge machining, the processing of abrasive air jet stream and exposure mask Electrolyzed Processing etc..Wherein, it covers
Film Electrolyzed Processing because have machined surface without remaining machining stress, without recast layer and can the advantages such as batch machining, by industry
Extensive concern.In conventional mask Electrolyzed Processing, exposure mask generally by photoetching process preparation on workpiece anode, often need gluing,
The series of steps such as front baking, exposure, rear baking, development, preparation process complexity is cumbersome, and each exposure mask is used only once, processing
It must destroy and get rid of after the completion；On the other hand, since technical capability is limited, existing photoetching process is extremely difficult in songs such as cylindrical surfaces
The photo etched mask of high-quality is prepared on face.
It needs to prepare and paste de- deficiency on workpiece repeatedly to solve conventional mask Electrolyzed Processing, domestic and international many scholars do
Numerous studies.Then, movable exposure mask Electrolyzed Processing is developed.In this approach, needed for exposure mask is pre-machined out
Patterning, then by being mechanically fixed rather than bonding mode is covered on workpiece anode, after processing is completed, exposure mask can be anti-
It is used in other workpiece again, in this way, substantially increase the ease-to-operate of technique and reduce process costs, it is raw convenient for batch
It produces.However, the key and difficult point of movable exposure mask Electrolyzed Processing are: how to realize that reusable exposure mask is reliably closely adhered to work
On part, especially when workpiece is the curved bodies such as cylindrical surface.
In order to solve the problems, such as the fitting of movable exposure mask, application No. is 201610860179.7 patents to propose using energy certainly
Body is as cathode and can assist overlaying the technical solution of exposure mask as the metal porous medium of mass transfer channel.The patent is proposed
Scheme significantly simplify exposure mask paste operation, realize the uniform of exposure mask and reliably overlay, while improving processing effect
Rate and machining accuracy, but device involved by scheme is only applicable to the processing of flat work pieces, for curve surface work pieces such as cylindrical bodies, also needs
Want special device.Therefore, this patent is directed to the movable exposure mask Electrolyzed Processing of cylindrical surface workpiece, proposes a kind of more based on metal
The new device of hole medium.
Summary of the invention
The purpose of the invention patent can be fitted on cylindrical surface there is provided a kind of, process gap movable exposure mask is fixed
Small, interpolar mass transfer transmits movable exposure mask electrolysis that is smooth and can disposably processing micro-pit array on 360 ° of cylindrical surfaces and adds
Tooling is set.
In order to achieve the above objectives, the technical scheme adopted by the invention is that:
A kind of device for cylindrical surface exposure mask Electrolyzed Processing, including workpiece anode, exposure mask, foam metal piece, bolt spiral shell

When work, foam metal piece, exposure mask and workpiece anode are sequentially placed in order, preceding gasket and rear gasket difference
It covers at the both ends of foam metal piece, then adapter sleeve is put on and contacts its both ends with preceding gasket and rear gasket respectively, press
It is placed with sealing block between plate I and pressing plate II, compresses pressing plate I and pressing plate II finally by unit bolt nut part.Pressing plate I with
There is gap between pressing plate II, the gap between pressing plate I and pressing plate II is maximum at adapter sleeve inner surface, and along the radial direction of adapter sleeve
Direction is sequentially reduced, thus when pressing plate I and pressing plate II it is close to each other by pressing force when, sealing block also will receive pressing plate I with
The extruding of pressing plate II and move down, it is thus golden in foam until contact with preceding gasket and rear gasket and mutual extrusion
Belong to and forms closed cavity between piece, preceding gasket, rear gasket, adapter sleeve and sealing block.The electrolyte being pumped to is from fastening
The inlet covered on the equally distributed boss in outer surface enters, and is conducive to create uniform electrolyte disengaging condition in this way.It flows into
Electrolyte be first stored in cavity, then reach workpiece anode quilts by interconnected holes many inside foam metal piece
Machining area.Workpiece anode connects positive pole, and foam metal piece connects power cathode, is not covered by the mask on such workpiece anode
The reaction of electrochemistry ablation will occur for region.Electrolysate and superfluous electrolyte can only be arranged by the side of foam metal piece
Out.Since the inner surface and workpiece anode of adapter sleeve are cylindrical surface, foam metal piece is easy to compressive deformation, as long as in adapter sleeve
Surface diameter, preceding gasket and mat thickness, sealing block thickness, foam metal piece thickness, mask thicknesses and cylindrical body work are sealed afterwards
Cooperate appropriately between part anode diameter, exposure mask can be pasted closely on the surface of the workpiece.
Compared with prior art, the invention has the advantages that cylindrical workpiece table easily can be closely adhered to exposure mask
Face can disposably process micro-pit array on 360 ° of cylindrical surfaces, and smoothly, processing gap is small for electrolysate discharge, processing essence
Degree is high.
