[0002] Wire cutting machine is a machine tool that uses pulsed electric spark to erode the processed material for cutting. Its main working principle is to use moving molybdenum wire, copper wire or alloy wire as electrode wire, and rely on pulsed spark discharge between the electrode wire and the workpiece to make the metal cutting wire discharge and generate heat. When the heat of the metal cutting wire is greater than the melting point of the workpiece material, the high temperature generated by the metal cutting wire will melt or vaporize the workpiece to form a cutting seam, thereby achieving the purpose of cutting the workpiece, and using the working fluid medium to reduce the temperature of the workpiece and the metal cutting wire, slow down corrosion, absorb vibration and reduce noise, etc. The cutting machine cuts the metal workpiece into different shapes through CNC control; When some existing EDM cutting machines on the market are in use, the coolant tends to flow everywhere and easily come into contact with and soak into the moving parts that release the metal cutting wire, causing the wire reel and electronic parts such as the drive motor to be easily soaked in the coolant and damaged.

[0013] Preferably, the outer surface of the second platform is provided with a plug-in filter mechanism, through which the coolant can enter the interior of the second platform after cooling the metal workpiece and the cutting wire, and can precipitate and filter the residue in the coolant.

[0014] By adopting the above technical solution, during cutting, the coolant can be guided by the protective cover and the blocking strip to flow into the interior of the second platform, so that the coolant can be concentrated inside the second platform instead of flowing around. The coolant can also be guided through the grooves in the second platform, and the metal residue in the coolant can be precipitated through the guidance movement.

Then the coolant will be concentrated on one side of the second platform through the inclined groove. Then, the coolant will be sucked out from the water outlet through the filtration of the filter mesh, so that the coolant can be circulated for use. At the same time, the remaining coolant in the second platform can be intuitively seen for easy addition.

[0017] Preferably, a rotating scraping mechanism is provided between the crossbeam and the wire drum rotating module, and the outer surface of the metal cutting wire can be kept clean by the rotating scraping mechanism.

[0018] By adopting the above technical solution, the oil and impurities on the outer surface of the metal cutting wire can be cleaned when the metal cutting wire moves, so as to keep the outer surface of the metal cutting wire clean and reduce the cutting error caused by dirt adhering to the outer surface of the cutting wire.

[0020] By adopting the above technical solution, the first guide wheel and the second guide wheel can be used to limit the released metal cutting wire so that the metal cutting wire can remain vertical. When the metal wire is guided by the first guide wheel and the second guide wheel to move, the metal cutting wire will pass through the clamping block and rub against the cleaning sponge installed in the clamping block. The dirt on the outer surface of the metal cutting wire will be scraped off and removed by the cleaning sponge, and the dirt will be washed away by the flowing coolant, so that the dirt will not accumulate on the outer surface of the clamping block, and the clamping block can be easily removed to replace the cleaning sponge.

[0021] Preferably, a pump casing is fixedly mounted on the outer surface of one end of the gantry away from the protective cover, and a rotating and pushing mechanism is provided between the pump casing and the servo motor. When the wire drum rotating module is moved and the metal cutting wire is released by the rotating and pushing mechanism, the coolant stored in the second platform can be drawn out together, so that the coolant can be released for cooling while the metal cutting wire is released.

[0022] By adopting the above technical solution, the coolant stored in the second platform can be discharged, the cutting point between the metal cutting wire and the workpiece can be cooled, the temperature of the metal cutting wire and the workpiece can be reduced, the cutting accuracy can be improved and the loss of the metal cutting wire can be reduced.

[0024] By adopting the above technical solution, when the servo motor rotates and drives the sliding screw to rotate, it will drive the wire reel rotating module to move, and the rotation of the servo motor will also drive the cam to rotate. The rotation of the cam pushes the elastic piston rod to slide inside the gantry, allowing the elastic piston rod to reciprocate inside the pump housing. With the use of the one-way valve, the coolant stored in the second platform can be pumped into the pump housing and discharged from the pump housing through the movement of the elastic piston rod, so that the coolant can be pumped into the universal liquid spray nozzle, and the coolant sprayed from the universal liquid spray nozzle can cool the metal cutting wire and the workpiece, allowing the wire reel rotating module to move back and forth to discharge and cut the workpiece, while spraying coolant for cooling. When the wire reel rotating module stops moving to release the wire, the coolant stops spraying from the universal liquid spray nozzle.

[0025] Compared with the prior art, the invention has the following beneficial effects: the double-gantry wire cutting machine tool with double wire drums: 1. When the coolant flows to the workpiece and the cutting wire, the coolant can be blocked by the protective cover and the blocking strip on the outer surface, and the tilted design of the crossbeam makes the coolant flow only toward the second platform. The coolant can be guided by the blocking strip and the block-shaped protrusions on the outer surface of the crossbeam, so that the coolant can be guided to flow into the second platform, so that the coolant will not flow into the inside of the crossbeam, so that the coolant cannot infiltrate the wire barrel rotating module, the third limit switch, the sliding screw and the servo motor, thereby reducing the probability of damage and extending the service life; 2. When the wire drum rotating module rotates and moves inside the crossbeam, the metal cutting wire will be released and wound in an orderly manner, so that the metal cutting wire can move under the guidance of the first guide wheel and the second guide wheel. When the metal cutting wire moves and passes through the clamping block, the cleaning sponge inside the clamping block can scrape and scrub the dirt on the outer surface of the metal cutting wire, and the dirt wiped off the outer surface of the clamping block can be washed by the flow of coolant, so that the dirt on the outer surface of the metal cutting wire can be cleaned, thereby improving the service life of the metal cutting wire and the cutting accuracy of the workpiece; 3. When the coolant flows through the diversion of the protective cover and enters the interior of the second platform, the second platform will store and collect the coolant, and the residual metal powder in the coolant can be precipitated through the groove in the second platform, and the coolant is concentrated to the water outlet on one side of the second platform through the inclined groove, and the remaining metal residue in the coolant is blocked by the filter plug net, so that the coolant can be filtered and circulated for use. At the same time, the remaining coolant can be visually viewed through the second platform, which is convenient for checking the remaining amount of coolant and adding it; 4. When the wire drum rotating module rotates and moves to release the wire, the servo motor will rotate continuously and drive the cam to rotate together, so that the cam can push the elastic piston rod to slide inside the gantry, and the elastic piston rod can move back and forth inside the pump housing. Through the cooperation of the one-way valve, the coolant in the second platform can be sucked into the inside of the pump housing, and the coolant in the pump housing is also pushed out by the elastic piston rod, so that the coolant can be pushed into the universal spray nozzle, and the coolant in the universal spray nozzle can be sprayed onto the metal cutting wire and the workpiece to cool the cutting part of the workpiece, so that the coolant can be continuously sprayed out from the universal spray nozzle when the wire drum rotating module rotates to release the wire, and the coolant can stop spraying when the wire drum rotating module stops.
