Abstract
An electrolyzing method for preparing the cellular micropits structure includes such steps as making a tool as cathode with a group of through holes and a shielding film on its surface, uniformly spraying the electrolyte through said through holes onto a workpiece as anode, and electrolyzing.
Description
Technical field
Electrochemical machining method in cellular dimple structure of the present invention belongs to technical field of electrolysis processing.
Background technology
Electrolyzed Processing is a kind of special processing technology, and it is to utilize electrochemistry anodic solution principle to remove the processing method of material.It is fast that it has process velocity, and surface quality is good, and instrument is lossless, is not subjected to restriction such as the strength of materials, toughness, hardness and do not have outstanding advantage such as macroscopical cutting force, obtained using widely in industries such as Aero-Space, weapons, automobile, mould.
Surface texture with cellular dimple is widely used in the cylinder inner surface as the approach that improves sliding friction, and its manufacture method adopts pit machining method commonly used at present to have four kinds usually: 1. self-excited vibration processing method.Guarantee to have at the cylinder sleeve working surface under essentially smooth the situation, utilize the self-excited vibration effect in the process to produce from the teeth outwards along the equally distributed miniature pit of the hand of spiral.This processing method, operation is many, and efficient is low, and amplitude and frequency adjustment are cumbersome, and little hole size, the degree of depth and being distributed in to a certain extent is restricted; 2. vibratory impulse processing method.Little hole vibratory impulse processing unit (plant) is contained on the middle carriage of lathe, workpiece to be machined is contained on the machine tool chief axis with certain speed rotation, little hole vibratory impulse processing unit (plant) can be vertically and the horizontal direction feeding, control the degree of depth in little hole by traverse feed, on the tool heads of device, apply low-frequency vibration by the driven by motor eccentric stiffener, rely on vibratory impulse on workpiece, to form little hole with certain regularity of distribution and certain size parameter, this processing method, make surface of the work that plastic deformation take place, jagged and material protuberance needs secondary operations sometimes around little hole; 3. digital control laser honing technique.Laser honing is made up of three process: the thick top gem of a girdle-pendant, and the laser stereo lithography and the smart top gem of a girdle-pendant are used to laser to dig a pit, hole, etc., and realize the surface micro-pit Mechanical Builds, and then carry out honing, this processing method cost height; 4. the little hole of Ultrasonic machining technology.The surface micro-pit ultrasonic machining device is contained on the middle carriage of lathe, processed parts with frication pair is contained on the machine tool chief axis with certain rotating speed rotation, little hole ultrasonic machining device can be vertically and the horizontal direction feeding, control the degree of depth in little hole by traverse feed, promote the luffing bar by ultrasonic tr-ansducer and apply ultrasonic vibration, rely on vibratory impulse to form little hole at the cylinder sleeve working surface with certain regularity of distribution and certain size parameter to tool heads.This processing method, required lathe rotating speed is very high, needs the development special purpose machine tool, and is not suitable for the processing of miniature workpiece.
Use analog structures such as electrochemical machining method processing group hole, group's seam to mainly contain following several at present: the electrolysis of 1. taking a picture.At first at workpiece to be processed surface-coated one deck photoresist, after painting and develop, light formed hollow out group sectional hole patterns at surface of the work, with exposed workpiece part chemistry or electrochemical corrosion, form group's pore structure, remove the workpiece that photoresist just can obtain to have cellular dimple structure at last.This method operation is loaded down with trivial details, and processing all needs the repetition above-mentioned steps with each part of a collection of workpiece; 2. use the special electrode Electrolyzed Processing.The fine metal silk is wrapped on the specific frame forms the wire wound tooling group and stitch electrode, or make the group's electrode tool group pore electrod with single micro fine cylindrical, tool-electrode to the workpiece feeding, can process corresponding group's seam and group hole with certain speed.This method electrode is made loaded down with trivial details, and the preparatory period is long.3. arrange micro-electrode processing.Use several micro-electrode Electrolyzed Processing one rounds of row, after finishing, reprocess another row, all machine until the group hole.If use this several manufacture method processing cellular dimple structures, processing technology is loaded down with trivial details, manufacturing cost is too high, and therefore, it is good to be necessary to study the efficient height, the surface quality that make new advances, the solution of the processing cellular dimple that cost is low.
Summary of the invention
The objective of the invention is to solve present cellular dimple structure and process that ubiquitous efficient is not high, surface quality is not high, the defective that manufacturing cost is too high, provide a kind of high efficiency, great surface quality, the electrochemical machining method in cellular dimple structure of low manufacturing cost.
A kind of electrochemical machining method in cellular dimple structure is characterized in that may further comprise the steps:
(1), one of making has and runs through group pore structure, surperficial tool cathode with screened film; (2), during Electrolyzed Processing, tool cathode and the workpiece anode made are placed in opposite directions; (3), in the Electrolyzed Processing, run through group hole to the even jet electrolytic liquid of workpiece anode by tool cathode; (4), switch between workpiece anode and the tool cathode, to the workpiece Electrolyzed Processing.
Because this processing mode is tool cathode and anode to fit tightly (middle rise shield and the screened film of insulating effect belongs to the part of tool cathode), this and traditional Electrolyzed Processing mode are very different.In traditional Electrolyzed Processing, leave an electrolyte flow channel between tool cathode and the workpiece anode.And the present invention adopts and runs through group pore structure as electrolyte flow channel on the tool cathode, promptly as feed pathway, also as liquid outlet channel.Electrolyte sprays to the tool cathode surface under the effect of pump, arrive tool cathode and this zone of workpiece anode by the cathode fixture internal cavities, at this moment group's pore structure is the flow channel of solution, also is the flow pass of solution, and electrolyte enters flow pass by the runner of cathode fixture again.This moment, tool cathode ran through the interior ancient piece of jade, round, flat and with a hole in its centre in group hole and the electric field between the workpiece anode has been removed main effect to the workpiece anode material.Adopt this electrochemical machining method, only apply steps such as photoresist, photoetching, development, etching in tool surfaces, form tool cathode, or have the through hole structure by other technology formation, the surface has the tool cathode of screened film.And anode is without any need for suchlike step, just can Electrolyzed Processing after tool cathode clamps it, workpiece need not secondary operations after the process finishing.The most important thing is,, this means and to produce in batches easily so long as processing just need not be changed tool cathode with a kind of part.The once electrolytic that can realize cellular dimple structure shapes, and has improved working (machining) efficiency, has reduced processing cost.
