Description
Technical field
The present invention relates to electric spark machining field, specifically, relate to a kind of efficient electric spark machining working solution.
Background technology
Edm is in certain medium, utilizes the galvano-cautery phenomenon when pulse feature discharges between tool-electrode and the piece pole that material is processed, to reach the certain geomery and the processing method of surface roughness requirement.In the little gap of liquid medium, carry out individual pulse when discharge, the electrical corrosion of material is broadly divided into conversion and the transmission of formation, the energy of the puncture of medium, passage, three the continuous processes of dishing out of galvanic corrosion product.When electrically conductive workpiece is carried out processing and forming, must be full of liquid medium between two electrodes, this liquid medium is aforesaid edm working solution.
The edm working solution must have higher dielectric strength, to help producing the spark discharge of pulse feature.The main effect of edm working solution is to keep appropriate insulation intensity between tool-electrode and the workpiece; The compression discharge channel; Discharge energy is focused in the minimum zone, get rid of the product in the discharging gap, electrode and workpiece are in time cooled off; The catabolite of working solution produces the plating effect to electrode in addition, helps reducing the loss of electrode.
Following three phases has been experienced in the development of edm working solution:
One, the 50-60 age in 20th century: water base, oil base two big series are also used period, make water and general mineral oil basically, like kerosene, transformer wet goods.
Two, the 70-80 age in 20th century: begin production spark machined special oil, promptly suitable mineral oil adds an amount of additive, contains than polyaromatic in the oil.
Three, the 80-90 age in 20th century: along with environmental requirement improves, the lathe upgrading begins to occur the efficient electric spark machining working solution of synthesis type, high-speed type and mixed type (edm oil, electric spark machine oil).
The edm working solution all was to use kerosene basically in the past.The shortcoming of kerosene is obvious, mainly is because flashing point low (about 46 ℃), can add that its arene content height is volatile because of the accident carelessness causes fire in the use, and processing decomposites many or the like the reasons of pernicious gas.And when working (finishing) area is big, in the kerosene working solution, be difficult for carrying out stable fine finishining, can not get good finished surface.In addition, working (machining) efficiency in the kerosene and export license neither be very satisfactory.
Efficient spark machined is a kind of form of edm.Inventor of the present invention is through adding the mode of additive in the edm working solution; Having investigated the various liquid additive investigates different angles such as the discharge waveform of efficient spark machined, processing speed, export license, machining accuracies; And take all factors into consideration, be exclusively used in the working solution of efficient spark machined below having invented.
Summary of the invention
The objective of the invention is to develop the efficient electric spark machining working solution of a kind of long service life, flash-point height, good processability.
For this reason; The technical scheme that the present invention taked is: a kind of efficient electric spark machining working solution; It comprises following component and content: oleic acid: No. 100 machinery oil of 6-12wt%, atoleine: 5-12wt%, APEO: 5-12wt%, higher aliphatic: 2-5wt%, sodium molybdate: 0.5-1.0wt%, nanometer additive: 0.05wt% and surplus.
Preferably, higher aliphatic of the present invention is that carbon number is the fatty alcohol of 16-20.
Preferably, APEO of the present invention is an APES.
Preferably, additive of the present invention is nano silica fume or Nano graphite powder, and the average diameter of preferred said nano particle is 5-15nm, and maximum gauge is no more than 25nm.
In addition; The present invention also discloses the preparation method of above-mentioned efficient electric spark machining working solution; At first No. 100 machinery oil, oleic acid, atoleine, APEO and higher aliphatics are added in the agitated reactor and be heated to 80-100 ℃; Add sodium molybdate and additive and fully mix, be incubated 10-25 minute, obtain above-mentioned efficient electric spark machining working solution.
Efficient electric spark machining working solution of the present invention has the following advantages than the kerosene working fluid of prior art:
(1) lightning is high, and far above the lightning of 46 ℃ of common kerosene, thereby its edm security is good.
(2) processing performance is good, and the workpiece surface finish that obtains after the processing is high, and the surface roughness after the processing obviously is superior to common kerosene, and described working solution can not corrode workpiece material, and it can suppress the aerial corrosion of workpiece on the contrary.
(3) be particularly suitable for efficient spark discharge processing, help shortening process time.
(4) be not easy to produce mist of oil in the use, can not produce harmful effect lathe.
