Description
The present invention relates to a kind of electromachining equipment of processing various conductive materials, especially for high efficiency processing high rigidity, high tenacity, high strength and high fragile material.
The processing high rigidity, high strength, high viscosity, difficult-to-machine material is as tungsten carbide, cermet, the titanium base, Ni-based, iron-based, molybdenum-base alloy, titanium alloy, rich chromium cast iron, difficult-to-machine materials such as white iron, especially surface irregularity, the roughing that cutting output is big, it is a great problem of machined and electric machining or other processing method always, the productivity ratio that traditional diamond-making technique is general is very low, the cost height, energy consumption is big, the lathe quick abrasion, need expensive cutter, abrasive material, or labour intensity is big, or the processed finished products rate is low, and it becomes an a great problem that urgency is to be solved of metal manufacture field.
CN87106421A discloses a kind of discharge and mechanical grinding associating method for processing and equipment thereof, is used to process the metal material of high rigidity.But because its limited working (machining) efficiency and precision, still can not be satisfactory.
The object of the present invention is to provide a kind of electromachining equipment of processing various conductive materials, especially for processing high rigidity, high tenacity, high strength and high fragile material expeditiously.
Another object of the present invention provides a kind of improved working solution.
These and other objects of the present invention and advantage can be understood from following narration.
Electromachining equipment according to the present invention comprises: lathe, supply unit and working fluid system.Instrument is rotatably installed on the lathe.One workpiece is connected with the output of supply unit with instrument.Add man-hour, instrument is by motor-driven rotation, and working fluid system is drenched working solution and is sprayed on instrument and the workpiece.During roughing, operating voltage and electric current are respectively 25V～28V and 1600A～3000A; During fine finishining, be 1V～9V and 1A～90A
Fig. 1 is the structural representation of present device.
Fig. 2 is the structural representation of supply unit.
Referring to Fig. 1, figure notation 1 expression one lathe, this lathe can be conventional lathe, building-block machine or the special purpose machine tool of various remodeling.One workpiece is installed on the lathe 1 by conventional methods, and with power supply an output-in the present embodiment for output head anode is connected, supply unit will be described in detail hereinafter.Workpiece can be to be made by the conductive material of any high rigidity, high tenacity, high strength and high fragility, as tungsten carbide, cermet, white iron etc.Figure notation 5 expression one instrument, it is rotatably installed on the lathe, and with another output of power supply-be connected for negative pole of output end in the present embodiment.Instrument is a disc-shape.It can be made by various conductive materials, and preferably the thickness of copper or copper alloy tool shelf can be 1～40mm, 16～18mm preferably, and the diameter of tool shelf can be 5～2000mm.Preferably on the circumference of tool shelf, be provided with at least one skewed slot.Groove width can be 4～5mm.Figure notation 2 expression is used for seal that lathe and workpiece, instrument are insulated.
Working fluid system 6 is used for the working solution pouring is sprayed on workpiece and the instrument, and described working solution is an inorganic aqueous solution.This working solution is the same with conventional cooling fluid, can be used to cool off workpiece and instrument, prevents that heat from importing workpiece and tool interior into.In addition, in the present invention, working solution also has " sensitization " effect, promptly under the effect of heavy current, when the workspace generation has a large amount of heat, impels the material that melts on the workpiece to break away from surface of the work to finish processing.Preferably use the electrolyte aqueous solution of low concentration.Because it also has antirust and antisepsis, thereby can produce the service life that excellent protection also can prolong lathe to workpiece.The low concentration electrolyte aqueous solution that has even have better rust inhibition is 0.01% to 5%(weight as: concentration) NaNO
2The aqueous solution, the NaOH aqueous solution or concentration are respectively 0.01% to 5%, and preferably 1%, the Na of (weight)
2CO
3And NaNO
2Mixed aqueous solution.Because the electrolysis of working solution is inoperative to processing, the composition of contained solute and quantity still remain unchanged after use in the working solution.Thereby used working solution can be collected by working fluid system, reuses after filtration with after the dilution.
Referring now to Fig. 2 supply unit of the present invention is described, shown in the figure is a three phase mains device.But it will be appreciated that supply unit is not limited in this.Six phase supply units, the supply unit of continuous-current plant and other type also is fine.As for the rectifying part of supply unit, then can use various devices, as halfwave rectifier or full-wave fairing attachment.But three phase half wave rectification is better, shown in present embodiment.Supply unit provides the electric current with low frequency, as the per second in the present embodiment 150 times.The maximum working voltage of supply unit can reach 30V, and correspondingly, maximum operating currenbt can reach 3000A.
Add man-hour, according to type and the shape of workpiece and the shape of surface to be machined of lathe, workpiece can be static, or rectilinear motion or rotation.The linear velocity of workpiece is less than 1m/s.Instrument can be by motor (not shown) rotation.The linear velocity of arbitrfary point should be greater than 10m/s, preferably greater than 30m/s on the tool shelf circumferential surface.It is the mechanical pulsing of 150-30000rpm that the instrument of rotation produces frequency, and this mechanical pulsing helps processing.In non-contacting processing, the gap of 0.01mm to 0.1mm can be arranged between workpiece and the instrument; Perhaps, workpiece can instantaneously contact with instrument, and to carry out mechanical striking, this helps processing equally.During roughing, be to improve working (machining) efficiency, can be by supply unit output HIGH voltage and big electric current, as: operating voltage at 25V between the 28V, correspondingly, operating current at 1600A between the 3000A.With this understanding, per minute can be removed 300 gram materials from workpiece, thereby improves the working (machining) efficiency twice.During fine finishining, can adopt the operating current of 1V to the operating voltage of 9V and 1A to 90A.Machining accuracy depends on the size of operating voltage and electric current, but not the frequency that current device produced.Rough machined machining accuracy can reach 0.05mm, and fine finishining can reach 0.01mm.
The above is for realizing the explanation of best mode of the present invention.Those of ordinary skill in the art can be on the basis of the above description, and, with do not deviate from the present invention by appending claims institute restricted portion and spirit with prerequisite.Whole branches of the present invention are made remodeling and modification.
