Description
Technical field
The utility model relates to a kind of WEDM, is specifically related to the Wire-conveying mechanism of quick walk of a kind of accurate closed-loop control wire electrode tension that bidirectional reciprocating wire transporting type WEDM uses.
Background technology
WEDM utilizes the galvanic corrosion effect that electric spark pulsed discharge generation occurs between wire electrode and workpiece in working solution to carry out linear cutter.Due to the limited length of winding of single layer wire electrode on wire storage tube, need wire storage tube to make positive and negative direction frequent toward complex Alternating commutation, Wire-cut Electrical Discharge Machining continuously could be maintained for a long time.Want to obtain high efficiency, high accuracy and high-quality linear cutter, just require the wire electrode at the reciprocal high-speed motion in electric discharge processing district, controlledly must be straightened under the effect of a stable tension, between so soft resilient wire electrode and workpiece, just can have the electric spark pulsed discharge environment that stable.So WEDM is to the quality of wire electrode tension control performance, directly determine cutting efficiency and the crudy of this type of lathe.
In order to realize the control to line electrode tension force, the Wire-conveying mechanism of quick walk of existing good several belt electrode thread tension controlling functions on existing market.Wherein, representative more advanced Wire-conveying mechanism of quick walk can be the Chinese utility model patent of CN201493578U see notification number.Wire-conveying mechanism of quick walk structure disclosed in this utility model patent is as shown in Figure 1: comprise ring seal wire electrode 1, wire storage tube 2, the upper block 5 laying respectively at wire cutting machine upper and lower coil holder 3,4 end and lower tumbler 6, and the first communtation arm 9 and the second communtation arm 10 that the column 7 of wire cutting machine is relatively slidably connected in the horizontal direction; First communtation arm 9 two ends are supported with upper and lower first reverse wheel 11,12, second communtation arm 10 two ends and are supported with upper and lower second reverse wheel 13,14; Described annular enclosed wire electrode 1, from wire storage tube 2, through upper second reverse wheel 13, upper first reverse wheel 11, upper block 5, lower tumbler 6, lower first reverse wheel 12, lower second reverse wheel 14 first, is finally back to wire storage tube 2 again.Described first communtation arm 9 contacts for tension detect with the force cell 8 be fixed on column 7, and the second communtation arm 10 is driven by motor 15 and controls for tension force.
Inventor to each segment electrode silk that annular enclosed wire electrode 1 is separated into by each adjacent guide wheel or reverse wheel, carries out wire electrode tension dynamic test respectively.The result measured shows: when two way alternate wire transporting, the size of the dynamic tension of each segment electrode silk in annular enclosed wire electrode 1, is change along with wire storage tube 2 " receipts silk " and " putting silk " order and presents and alternately change.Namely the dynamic tension presented in distance wire storage tube 2 " receipts silk " nearlyer wire electrode section is larger; Otherwise the dynamic tension in the wire electrode section that wire storage tube 2 " putting silk " is nearer is less.This phenomenon is as acrobatics bicycle, and when ride forward by average rate for positive direction, first half chain is in tensioning state forever, and Lower Half chain is in relaxed state forever; When average rate is ridden in the other direction backward, otherwise the tensioning of upper and lower two parts chain and loose two states are then.In a word, when reciprocal two-way wire transporting, the size of the upper and lower part partial-tension of annular enclosed wire electrode 1 alternately changes, and the region of " receipts silk " and " wire feed " the closer to wire storage tube 2, its maximum tension and minimum tension difference larger.If the wire transporting structure of symmetry, that segment electrode silk of electric discharge processing district being in symmetrical configuration place-centric affects for minimum by the alternately commutation of wire storage tube 2, the tension force of that segment electrode silk is about near wire storage tube 2, is in " receipts silk " state comparatively hightension value and be in the mean value of " wire feed " state compared with both small tension receiving coils.
Mechanical analysis is carried out to above-mentioned prior art wire transporting structure: act on the component Fx that the first communtation arm there is horizontal direction and the moment of torsion My perpendicular to wire transporting plane.The difference of size=annular enclosed wire electrode 1 upper and lower two parts tension force twice of moment of torsion My, is multiplied by the half that the first communtation arm 9 installs the first reverse wheel 11, lower first reverse wheel 12 distance between axles.The reactive torque that this moment of torsion My is produced jointly by upper rail first slide block 16 and lower guideway first slide block 17 of fixing the first communtation arm 9 balanced.In horizontal direction component Fx=upper and lower ring electrode silk part compared with four times of small tension receiving coil.This horizontal component Fx is applied to through the first communtation arm and is fixed on the force cell 8 of column 7.Because wire storage tube 2 is when alternately commutation is moved, upper and lower first reverse wheel is in the region of " receipts silk " and " wire feed " by wire storage tube 2 all respectively, as can be seen here, there is larger error between the tension force of the annular enclosed wire electrode 1 detected by the force cell 8 in the prior art Wire-conveying mechanism of quick walk and real ring electrode thread tension, and then make the tension force of its servo-controlled annular enclosed wire electrode 1 equally also there is larger error.
