Background technology
Work in-process adopts standard milling cutter (as rose cutter) in the heart, by interpolation, walk complicated track and obtain complex-curvedly, is quite ripe technology.Traditional spark machined needs to make shaped electrode.Electric spark milling processing is a kind of novel mechanical processing technology, it be adopt as the electrode of the simple shape such as bar-shaped, tubulose as milling cutter according to the certain track motion, by the spark eroding between electrode and workpiece, the removal workpiece material obtains complex-curved.
Compare with traditional Electric Discharge Machining, electric spark milling has not only saved design and the manufacturing of shaped electrode, greatly enhances productivity, shorten the production cycle of product, reduce processing charges, improved the flexibility of processing, but also effectively improve processing stability, minimizing capacity effect.
But the development of existing electric spark milling technology has been absorbed in stagnation, and main problem is: during electric spark milling, the loss of electrode is uncontrollable.Adopt CCD optical pickocff or other sensor, timing or not timing suspend processing, and electrode is detected, and the compensating electrode loss is the method for present most study.But export license form, size are difficult to grasp, and the measurements interference factor is too many, and measuring accuracy can't guarantee, greatly affects working (machining) efficiency, makes it not possess practical value.And study, grasp the export license rule, thereby the prediction export license compensates, and is also the more method of studying at present.But the achievement in research that the method is present can't adapt to actual spark machined situation at all.
The utility model content
The purpose of this utility model is to address the above problem, and a kind of shaped electrode that both need not to prepare is provided, and need not again to consider the electric spark milling device of export license.
The technical scheme that realizes the utility model purpose is: a kind of electric spark milling device comprises pillar, hollow bearing, revolving dial, wire feeder, guide wheel and wire electrode.
Described hollow bearing is fixed on described pillar.
Described revolving dial is arranged on described hollow bearing, and can be around the axis rotation of described pillar.
Described wire feeder is fixed on described revolving dial, and can rotate by the axis around described pillar together with described revolving dial; Described wire feeder comprises storage silk wheel, some guide wheels and waste silk curled hair wheel.
Described guide wheel is arranged on the lower end of described pillar, and can be around the axis rotation of described pillar together with described revolving dial, and the circumference of described guide wheel is provided with arc groove.
The part of using in described wire electrode is in the arc groove of described guide wheel, in described wire electrode, an end of untapped part is in the storage silk wheel of described wire feeder, during one end of the part of having used in described wire electrode is taken turns around the waste silk curled hair of described wire feeder, and by waste silk curled hair wheel drive.
The good effect that the utlity model has: electric spark milling device of the present utility model has directly adopted the wire feeder in the unusual slow wire feeding electric spark linear cutting machine of mature and reliable, adding man-hour like this, wire electrode on rotatable guide wheel just is equivalent to a diameter, length all can not change " rose cutter ", so both need not to prepare shaped electrode, need not again to consider the electrode compensation problem, overcome the greatest difficulty in existing electric spark milling.
