Embodiment approach
[0039] As an optional implementation method of the present invention, the bulk density of the free insulating particles 4 is 0.8-1.2 times the density of the electrolyte 3 .
[0040] As an optional implementation method of the present invention, the diameter of a single free insulating particle 4 of the free insulating particles 4 is larger than half of the difference between the width of the slit and the diameter of the wire electrode 9 and smaller than the width of the slit.
[0041] Selecting the free insulating particles 4 with a bulk density close to the density of the electrolyte 3 can suspend them in the electrolyte 3 and press them densely into the processing area of the wire electrode 9 and the workpiece, so as to shield the stray electric field in the processed area . Selecting a single free insulating particle 4 whose diameter is larger than (kerf width-electrode diameter) / 2 and smaller than the kerf width can ensure the insulating effect of the particles without ...

The invention relates to a free insulating particle assisted electrolytic wire cutting processing device and method. The device includes: electrolyte tank, electrolyte, free insulating particles, workpiece to be processed, wire electrode and power supply; electrolyte is set in the electrolyte tank, free insulating particles are set in the electrolyte; one end of the workpiece to be processed and wire electrode One end of the wire electrode is inserted into the electrolyte, the other end of the workpiece to be processed is connected to the positive pole of the power supply, and the other end of the wire electrode is connected to the negative pole of the power supply; when the power is turned on, the electrolytic wire cutting process is carried out with the movement of the wire electrode; During the wire cutting process, the free insulating particles fill the electrolytic machining area between the wire electrode and the workpiece to be processed, and the free insulating particles rub the surface of the wire electrode and the surface of the workpiece to remove the electrolytic products attached to the surface of the wire electrode. The invention can shield and weaken the secondary corrosion of the processed area by the stray current, improve the processing precision and improve the surface quality of the workpiece to be processed.
Description
technical field [0001] The invention relates to the field of electrolytic processing, in particular to a free insulating particle assisted electrolytic wire cutting processing device and method. Background technique [0002] Electrolytic wire cutting processing technology is a special processing method in which metal wire or metal rod is used as the cathode of the tool, and the workpiece is used as the anode to undergo electrochemical dissolution reaction through the electrolyte. Electrolytic wire cutting has the advantages of no cathode loss; suitable for processing high hardness alloys; no recast layer and micro cracks on the processed surface. This method can not only process narrow slits and micro-grooves and large aspect ratio structures, but also can process complex ruled surface components combined with multi-axis numerical control motion. [0003] During electrolytic wire cutting, the electric field is mainly distributed in the processing gap between the wire electr...
