Description
Technical field
The present invention relates to electric spark machining field more particularly to a kind of unidirectional wire electric spark wire cutting method of double-station and
System.
Background technique
Electrical discharge machining is processed using pulse spark electric discharge removal machined material, machined electrode and be processed
Because there are liquid dielectrics not in contact with so the metal etc. that can be used softer electrode (tool) processing hard and crisp is led between material
Body and semiconductor material.Particularly suitable machining is difficult to competent high rigidity, high intensity, high-melting-point, high tenacity, high brittleness material
The processing for expecting (such as: tungsten-molybdenum alloy, memorial alloy, magnesium alloy, hard alloy, plycrystalline diamond diamond, neodymium iron boron), is widely used in
The precision in each fields such as mold manufactures, space flight and aviation, medical instrument, instrument and meter, electronic apparatus, machine-building is zero special-shaped
Processing, the manufacture of part.
It is answered in spark coil cutting processor bed with mobile line electrode machining tool (referred to as: electric spark linear cutting machine)
With the most extensively, account for about the 60% of electric spark machine tool total amount.Wire cutting machine tool can be divided into to-and-fro thread again and (be commonly called as " hurrying up
Silk " wire travelling speed 10-12m/s) and unidirectional wire (it is commonly called as " slow wire feeding " wire travelling speed 0.5-2m/s) two major classes type, high speed
Wire cutting machine is the electromechanical integration equipment with perfect knowledge property right of China's independent development capability, peculiar for China,
Its advantage is that cheap, silk (line) electrode can multiple Reusability.
China had developed " middle wire " wire cutting machine tool, meaning " middle wire " lathe, industry association is defined as: tool again in recent years
There is to-and-fro thread (fast wire winding) lathe of multiple cutting function.Unidirectional wire (slow wire feeding) machining accuracy is high but machine tool structure is complicated
Cost is high, and also high up to the present domestic and international market especially high-end market is monopolized by external manufacturer technical threshold substantially,
Its high efficiency (big energy) takes the wire travelling speed of 2m/s when cutting, then small energy finishing cutting, has reached high-precision and height
Surface roughness requirement." middle wire " is exactly the technique for imitating the first high efficiency of " slow wire feeding " and cutting and then refinishing cutting
Method, claiming " middle wire " is exactly to be different from " fast wire winding " and " slow wire feeding ".
The wire electrode (usually copper alloy silk) of current existing unidirectional wire (slow wire feeding) wire cutting is all once to pass through
Formula uses, wire electrode is directed by wire storage cylinder to processing district once discharge after leave processing district and be eliminated, especially small energy is repaired
The serious waste of wire electrode is caused when whole cutting；The wire electrode (usually molybdenum alloy thread) of to-and-fro thread (fast wire winding) wire cutting is
Multiple Reusability, but since to-and-fro thread uses the wire scheme of monofilament barrel, can only single layer wrapping wire, once upper filament length degree only has
200-300m, such as presses the wire travelling speed of 10m/s, at most runs 30s and just commutates, and frequently commutation cutting generates commutation striped, precision
Much it is worse than unidirectional wire cutting.
To-and-fro thread wire cutting (" in wire ") with multiple cutting function using after the cutting of first pass high efficiency again into
Row second time, third all over so that the 4th time finishing cutting method, greatly enhance machining accuracy and surface smoothness.
But the length of wire electrode is limited because being still monofilament barrel wire scheme, even if when finishing cutting being the wire travelling speed of 1m/s,
At most operation 300s just commutate, process frequently commutate formation commutation striped, and every time commutation have pause electric discharge with again
Forming discharge channel process causes electric discharge cannot be continual and steady, there is fatal influence to precision and surface smoothness.
Before applicants have invented " the reciprocal movement wire system of mariages cylinder variable-ratio and wire cutting machine tool ", system includes forward direction
Wire cylinder and reversed wire cylinder, positive wire cylinder and reversed wire cylinder are drivingly connected with a speed change winding motor respectively, positive
Wire cylinder and reversed wire cylinder are for drawing same root wire electrode.By being utilized respectively positive wire mode and reversed wire mould
Formula to wire electrode carry out two to traction, the rotation in direction receives or release electrode on each wire cylinder, while only
Silk, can be with multi-lay winding wire electrode without sleave, it is possible to the significant quantity for increasing the wire electrode stored on wire cylinder.
It does not commutate when cutting single element so as to realize, to eliminate the surface quality that commutation striped improves processing.
