Using computerized control system, the programming of Quan Zhongwen Automatic Drawing, control software.There are track, time showing in processing, can understand at any time
Wire has the characteristics that multiple cutting function in processing situation.
Existing electric spark linear cutting machine is mostly just in being arranged one layer of online arm and one layer of offline arm on column, and two
One layer of work rest is correspondingly arranged between line arm, workpiece to be cut is fixed on work rest, after the molybdenum filament between upper offline arm is powered
Workpiece is cut, the cutting efficiency of the electric spark linear cutting machine of the structure is lower, be once only capable of for workpiece into
Row cutting；And if multilayer workpiece frame is arranged to place each workpiece simultaneously by increasing the distance between online arm and offline arm
It is cut, needs the length for lengthening molybdenum filament, opposite molybdenum filament both ends need to load higher voltage, the fracture of Yi Fasheng molybdenum filament.
Patent document (CN201010137796.7) discloses a kind of electrode wire break-proof stabilizer of wire cutting machine tool, this is anti-breaking
Two are used when using on stabilizer cutting on line lathe, are separately fixed at wire electrode vertical direction upper and lower ends, wire electrode fortune
Wire electrode is pressed into arc by conducting block, thread pressing block and locating piece, thread pressing block by row, and thus vibration resistance is rested at guide wheel,
Resistance is larger when wire electrode operation passes through break-proof stabilizer, and the wire electrode discharge section operated between two break-proof stabilizers (is cut
Cut part) have always compared with hightension, work normally wire electrode.In view of the base of the electrode wire break-proof stabilizer of wire cutting machine tool
A kind of multilayer wire arm electric spark linear cutting machine with more high cutting efficiency how is designed on plinth, is worth those skilled in the art
Deep thinking.
Summary of the invention
In view of the above-mentioned defects in the prior art, the technical problem to be solved in the present invention is that providing a kind of multilayer wire arm electrical fire
Discharge machine bed improves cutting efficiency, while guaranteeing the security performance of molybdenum filament.Present invention design thus uses following scheme:
A kind of multilayer wire arm electric spark linear cutting machine, including lathe, and be set on lathe column, work rest and
Molybdenum filament cylinder is wound with molybdenum filament on the molybdenum filament cylinder, and the lower part of the column is equipped with offline arm, and the top of column is equipped with online
Arm, is equipped at least one middle line arm in the middle part of the column, and the both ends of the online arm are equipped with upper block, and the two of offline arm
End is equipped with lower tumbler, and the described one end of online arm far from column is equipped with conductive upper filar guide, institute below upper block
It states the one end of offline arm far from column and conductive lower filar guide is installed above lower tumbler, the middle line arm is in far from column
One end above and below be symmetrically installed there are two conductive middle filar guide, the molybdenum filament successively pass through molybdenum filament cylinder, upper block,
Upper filar guide, middle filar guide, lower filar guide and lower tumbler form closed loop configuration；The work rest includes at least two layers frame, is appointed
The meaning part frame is between two adjacent line arms；And corresponding one of the part frame per two adjacent line arms and between it is solely
Vertical high frequency electric source, two opposite filar guides connect the cathode of high frequency electric source by conducting wire on two adjacent line arms, adjacent
Two line arms between part frame the anode of high frequency electric source, and mutually insulated between each part frame are connected by conducting wire.
Further, the online arm and middle line arm are flexibly connected by lifting device with column.
The beneficial effects of the present invention are:
The configuration of the present invention is simple is reliable, in multilayer wire arm configuration is arranged on the column of lathe, while by the part on work rest
Rack-layer number is increase accordingly；It is correspondingly arranged one layer of part frame between every two adjacent line arm, it is opposite between two adjacent line arms
Filar guide passes through molybdenum filament, and filar guide is electrically conductive referring to electrode wire break-proof stabilizer of wire cutting machine tool structure in the prior art
Molybdenum filament is prevented to be broken simultaneously, two filar guides connect high frequency electric source cathode by conducting wire, and corresponding part frame then connects high frequency electric source
Anode is so equivalent to the line arm on column being divided into a cutting group two-by-two, by the molybdenum filament that connects between two line arms to part frame
On workpiece cut, different cutting groups use independent high frequency electric source, can be controlled separately on-off, while to each cutting group
The voltage of molybdenum filament load can be with original unanimously without improving, and each cutting group simultaneously cuts the workpiece on each layer part frame of work rest
It cuts, cutting efficiency at least can be improved twice or more, and not influence the safety of molybdenum filament.
