Description
Technical field
The utility model provides a kind of pneumatic atomizing rapid condensation magnetic abrasive material to prepare equipment, belongs to the magnetic abrasive finishing technical field of material.
Background technology
Magnetic abrasive finishing polishing processing technology is a kind of new polishing complete processing that magnetic field application is developed in traditional grinding technique; It is a kind of very excellent polishing processing method; Be to improve the effectively technique means of product surface quality.There is plurality of advantages technically in this method: flexibility, adaptivity, self-sharpening, controllability, temperature rise is little and need not carry out tool wear compensation, need not correction of the flank shape etc. characteristics; Also avoided complicated requirement simultaneously, can realize the grinding polishing processing of 3 D complex curved surface and solve automation issues the grinding tool head construction; And can reduce the manufacturing cost of part, thereby caused extensive studies at home and abroad.The preparation method of magnetic abrasive has a variety ofly in the prior art, and they can be divided three classes substantially: mechanical mixing, matrix material method, reaction casting.
Mechanical mixing is with uniform mixing at normal temperatures by a certain percentage such as ferromagnetic powder, abrasive powders and lapping liquid, directly carries out the method for attrition process.Ferromagnetic powder and the abrasive powders such as the Al of certain particle size commonly used
2O
3, SiC, Cr
2O
3, after TiC etc. mixes, add tackiness agent such as oleic acid, Vilaterm glycol, silica gel etc. again and process.This kind method can be processed multiple magnetic abrasive, and preparation technology is simple, and cost is low, but during grinding, abrasive grain and magnetic powder comparison separate easily are dispersed, and mill efficiency is low, has limited range of application.
See that from the angle of materialogy magnetic abrasive is a kind of composite powder, i.e. iron-based grains enhanced type composite material powder.It is the heterogeneous material of being processed through certain recombining process by two or more material, and its performance obviously is superior to starting material in particular aspects.Along with the development that matrix material is learned, the technology of preparing of magnetic abrasive has also obtained corresponding development, and its preparation technology has many kinds, mainly contains sintering process, mull technique, composite deposite method etc.
Sintering process is that present magnetic abrasive prepares the most frequently used method.In Japan, this method successfully is applied in the suitability for industrialized production.According to the difference of concrete sintering condition, it is divided into normal pressure-sintered, hot pressed sintering, laser sintered, microwave sintering etc. again.Owing to the processing characteristics and the work-ing life of magnetic abrasive, certainly be taken at abrasive particle and ferromagnetic bonding strength mutually to a great extent.The magnetic abrasive of sintering process preparation has the abrasive material of considerable part to be separated with ferromagnetic in mechanical disintegration, screening process, causes the ferromagnetic intensity that combines with abrasive particle to reduce, and durability descends.
Mull technique is divided into inorganic bond and organic adhesive according to the difference of selecting for use sticker; Be that certain proportion, the ferromagnetic powder that mixes and abrasive powders are bonded together with sticker; Solidify then, varigrained magnetic abrasive powder is processed in mechanical disintegration, screening again.The magnetic abrasive of mull technique preparation owing to do not need briquetting in advance, need not contain the equipment such as electric furnace, laser machine of rare gas element, so this method technology is simple, realizes that easily cost is lower.But tissue looseness, in conjunction with poor, density is low, poor heat stability, abrasive particle comes off mutually easily, and the life-span is shorter.And when temperature was higher, the agglutinating magnetic abrasive made the surface of processing become furvous, the easy contaminated damage of original finished surface.
The composite deposite method certain abrasive grain is mingled with in the metal plating equably, and the special coating that forms is composite deposite with the method for composite plating or composite chemical plating.Compound plating technology is applied in the technology of preparing of magnetic abrasive, through years of development, the composite deposite method successfully is applied in many sciemtifec and technical spheres, but production cost is higher, batch process is difficult to realize, plating bath is dealt with improperly also and can be caused environmental pollution.
Its principle of reaction casting is under certain condition; Through the chemical reaction between element and element or element and the compound; Synthetic one or more high-intensity ceramic enhancement phase of original position in human body; After obtaining containing the alloy of ceramic enhancement phase, the reheat fusing also under high pressure is blow molded into powder.The problem that the reaction casting exists at present is that the content of ceramic hard abrasive material in the magnetic abrasive is low and hard abrasive grain wherein is also restive.
Plasma spraying method is after being pre-mixed iron-based powder and hard abrasive grain evenly by a certain percentage, to be placed in the raw material powder feed chamber of plasma spraying equipment.In the Vakuumkammer of plasma spray injection device,, produce plasma jet flame by plasma generator to applying high frequency discharge voltage between two electrodes.The mixed raw materials powder constantly is injected in the plasma flame simultaneously, and the plasma flame temperature can reach 5000～10000 ℃ high temperature, and raw material powder constantly is fused into little drop, cools off, is frozen into spherical magnetic abrasive particle then.Though this kind method has solved iron-based and the abrasive material problem of consistency difference mutually; But the magnetic abrasive of this method preparation is owing to receive the high temperature action of plasma flame; The sharp cutting edge of abrasive particle phase is passivated; Cause its mill efficiency significantly to reduce, its mill capacity even the magnetic abrasive for preparing less than other simple methods.
The fast magnetic abrasive preparation method (people is proposed by the utility model) that coagulates of atomizing is to adopt the fast equipment that coagulates of atomizing, under the protection of rare gas element; High pressure draft with containing the hard abrasive material blows the molten metal flow of penetrating in the dirty process; After metal liquid stream is atomized, form the fine droplet that contains the hard abrasive grain, through quick cooled and solidified; The hard abrasive material of script consistency and wettability extreme difference is forcibly combined with metallographic phase mutually, thereby prepare high performance magnetic abrasive.This method has broken through the restriction of consistency difference between ferromagnetic metal and the hard abrasive material; With ferromagnetic metal and the hard ceramic abrasive material is enforceable combines, prepare have the permeance height, mill capacity is strong, controllable granularity, structural strength are high, structural form is high performance magnetic abrasive material spherical, that the life-span is long.This method promises to be the most promising method of producing the high performance magnetic abrasive material low-costly and in high volume at present.
