Description

Technical Field

[0001] This utility model relates to a slow wire EDM cutting machine, and more particularly to a slow wire EDM cutting machine with a cooling structure applied in the field of slow wire EDM cutting machine technology. Background Technology

[0002] Wire EDM, also known as low-speed wire EDM, is a CNC machining tool that uses a continuously moving thin metal wire (called the electrode wire, usually copper wire) as an electrode to perform pulsed spark discharge on the workpiece, generating temperatures above 6000 degrees Celsius to erode the metal and cut it into the workpiece. The principle of slow wire EDM is based on the phenomenon of continuous discharge removing metal through the gap between the wire electrode and the workpiece.

[0003] Chinese patent CN213702094U discloses a slow wire cutting machine that is easy to move. In this utility model, the output shaft of the first dual-axis drive motor drives the worm gear to rotate forward. According to the meshing transmission principle of the locking teeth, the worm wheel is driven to rotate, which drives the first transmission shaft to rotate, which in turn drives the cylindrical gear to rotate. According to the meshing transmission principle of the locking teeth, the adjusting plate moves vertically downward, the roller rolls into contact with the ground, and at the same time pushes the fixed plate away from the ground in the opposite direction. Under the rolling action of the roller, the slow wire cutting machine can be moved as a whole.

[0004] Chinese patent CN216607545U discloses a fixture for a slow wire EDM machine. This fixture, through the cooperation of a frame, a hydraulic cylinder, a first connecting rod, and a third clamping rod, adjusts the hydraulic cylinder to move the first connecting rod downwards. The first connecting rod then moves the first slider down along the slide groove of the frame. The first connecting rod causes the first clamping rod to rotate clockwise, while simultaneously causing the second and third clamping rods to rotate counterclockwise. This solves the problem of unstable fixation of cylindrical workpieces by the fixture in a slow wire EDM machine.

[0005] The cooling devices of existing wire EDM cutting machines typically use coolant for cooling. When the equipment is running, the coolant flows out from the liquid hole at the top. Because the liquid hole is vertically downward, most of the coolant cannot directly contact the wire EDM, reducing the cooling effect of the coolant on the wire EDM. Utility Model Content

[0006] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that, due to the vertical downward orientation of the liquid hole in the existing slow wire EDM cutting equipment, most of the coolant cannot directly contact the slow wire EDM, thus reducing the cooling effect of the coolant on the slow wire EDM.

[0007] To address the aforementioned problems, this utility model provides a slow wire EDM cutting machine with a cooling structure, comprising a cutting machine body, a groove on the cutting machine body, a slow wire EDM rotatably connected to the top of the cutting machine body directly above the groove, a connecting block rotatably connected to the bottom of the slow wire EDM, a limit block fixedly connected to the bottom of the connecting block, a base fixedly connected within the groove, a limit groove corresponding to the limit block at the top of the base, and the limit block engaging with the limit groove, a filter frame engaged within the groove, and a section extending to the side of the bottom wall of the groove. The machine body has a drain outlet. Electric push rods are symmetrically fixedly connected to both sides of the top of the machine body at the slow wire EDM location. The movable end of the electric push rod is connected to an annular water storage pipe, which is sleeved on the surface of the slow wire EDM. Multiple spray holes are equidistantly opened in an annular shape on the inner wall of the water storage pipe. A water inlet is opened at the top of the water storage pipe, and a connecting pipe is threaded into the water inlet. A self-rebound reel is fixedly connected to the top of the machine body at the side of the slow wire EDM location, and a connecting pipe is wound around the surface of the self-rebound reel. The end of the connecting pipe away from the water storage pipe is connected to a water tank through a suction pump.

[0008] In the aforementioned wire EDM cutting machine, an annular water storage pipe is installed, and the wire EDM is cooled comprehensively through spray nozzles. The height of the water storage pipe can be adjusted according to the size of the object being cut, so that the wire EDM can be cooled while the object at the bottom can be rinsed more effectively.

[0009] As a further supplement to this application, an extension frame is fixedly connected to the top of the groove on the cutting machine body, and a foldable transparent waterproof cover is fixedly connected to the inner wall of the groove.

[0010] As a further supplement to this application, a magnetic frame is fixedly connected to the top of the waterproof cover, and a magnetic plate is fixedly connected to the cutting machine body at the position directly above the groove, and the magnetic frame and the magnetic plate attract each other.

[0011] As a further supplement to this application, a dustproof mechanism is detachably connected to the water storage pipe, the dustproof mechanism including an upper clamping plate and a lower clamping plate that are symmetrically arranged.

[0012] As a further supplement to this application, the upper card plate and the lower card plate are respectively fixedly connected to a card slot and a card block at one end close to each other, and the card slot and the card block engage with each other.

[0013] As a further supplement to this application, a dustproof net is fixedly connected to the inner wall of the upper plate, and the bottom of the dustproof net abuts against the lower plate.

[0014] As a further supplement to this application, an annular electric guide rail is fixedly connected to the top of the upper plate, and a cleaning brush is slidably connected to the electric guide rail via a slider, and the cleaning brush is in contact with the dustproof net.

[0015] In summary, when using the cutting machine body, the suction pump can be turned on via the controller to deliver coolant to the water storage pipe through the connecting pipe. The coolant is then sprayed onto the wire EDM machine through the annularly arranged nozzles for all-around cooling. During this process, the electric actuator can be turned on via the controller to adjust the height of the water storage pipe, thereby adjusting the distance between the water storage pipe and the wire EDM machine according to the size of the object to be cut. As the water storage pipe moves, the connecting pipe is adjusted in length by the self-rebound reel. The powder and debris generated during the cutting process mix with water and fall onto the filter frame in the groove for filtration. The filtered wastewater is discharged through the drain outlet. After the cutting operation is completed, the operator must first stop the equipment and then pull the limit block out of the limit groove. At this time, the filter frame can be removed from the groove to clean the filtered powder. Attached Figure Description

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-4This invention discloses a wire EDM cutting machine with a cooling structure, comprising a cutting machine body 1, a groove 3 on the cutting machine body 1, a wire EDM 16 rotatably connected to the top of the cutting machine body 1 directly above the groove 3, a connecting block 15 rotatably connected to the bottom of the wire EDM 16, a limiting block 17 fixedly connected to the bottom of the connecting block 15, a base 14 fixedly connected inside the groove 3, a limiting groove 18 corresponding to the limiting block 17 having a top of the base 14, and the limiting block 17 engaging with the limiting groove 18, a filter frame 19 being engaged inside the groove 3, and a side wall extending outwards from the cutting machine body 1 having a side wall extending outwards from the bottom of the groove 3. The drain outlet 8, the top of the cutting machine body 1 is symmetrically fixedly connected to the two sides of the slow wire EDM 16, the movable end of the electric push rod 7 is connected to the annular water storage pipe 6, and the water storage pipe 6 is sleeved on the surface of the slow wire EDM 16. The inner wall of the water storage pipe 6 is provided with multiple spray holes at equal intervals in an annular shape, the top of the water storage pipe 6 is provided with a water inlet 24, and the water inlet 24 is internally threaded with a connecting pipe 25. The top of the cutting machine body 1 is fixedly connected to the side of the slow wire EDM 16, and the connecting pipe 25 is wound around the surface of the self-rebound winding 10. The end of the connecting pipe 25 away from the water storage pipe 6 is connected to a water tank through a suction pump.

[0027] The main body 1 of the cutting machine is fixedly connected to a controller for the electric push rod 7, the electric guide rail 20, and the suction pump.

[0028] Working principle: When using the cutting machine body 1, the suction pump can be turned on by the controller to deliver coolant to the water storage pipe 6 through the connecting pipe 25. The slow wire 16 is cooled by spraying coolant through the annularly arranged nozzles. During this process, the electric push rod 7 can be turned on by the controller to adjust the height of the water storage pipe 6, thereby adjusting the distance between the water storage pipe 6 and the slow wire 16 according to the size of the object to be cut. During the movement of the water storage pipe 6, the connecting pipe 25 is adjusted in length by the self-rebound reel 10. The powder and debris generated during the cutting process are mixed with water and fall onto the filter frame 19 in the groove 3 for filtration. The filtered wastewater is discharged through the drain 8. After the cutting operation is completed, the operator must first stop the equipment and then pull the limit block 17 out of the limit groove 18. At this time, the filter frame 19 can be removed from the groove 3 to clean the filtered powder.

[0029] This invention features an annular water storage pipe 6 that provides comprehensive cooling to the wire EDM 16 via spray nozzles. The height of the water storage pipe 6 can be adjusted according to the size of the object being cut, allowing for better rinsing of the object at the bottom while cooling the wire EDM 16.

[0030] Second implementation method:

[0031] Figure 1 and Figures 5-6An extension frame 2 is fixedly connected to the top of the groove 3 on the main body 1 of the cutting machine. A foldable transparent waterproof cover 4 is fixedly connected to the inner wall of the groove 3. A magnetic frame 5 is fixedly connected to the top of the waterproof cover 4. A magnetic plate 9 is fixedly connected to the main body 1 of the cutting machine directly above the groove 3. The magnetic frame 5 and the magnetic plate 9 attract each other. A dustproof mechanism is detachably connected to the water pipe 6. The dustproof mechanism includes an upper card plate 22 and a lower card plate 23 that are symmetrically arranged. The upper card plate 22 and the lower card plate 23 are respectively fixedly connected to a slot 12 and a block 11 at one end close to each other. The slot 12 and the block 11 engage with each other. A dustproof net 21 is fixedly connected to the inner wall of the upper card plate 22. The bottom of the dustproof net 21 abuts against the lower card plate 23. An annular electric guide rail 20 is fixedly connected to the top of the upper card plate 22. A cleaning brush 13 is slidably connected to the electric guide rail 20 through a slider. The cleaning brush 13 contacts the dustproof net 21.

[0032] Working principle: The upper plate 22 with dustproof net 21 is clamped above the water storage pipe 6, and the lower plate 23 is clamped at the bottom of the water storage pipe 6, so that the corresponding clamping block 11 and the clamping slot 12 are engaged, and the upper plate 22 and the lower plate 23 are fixed. At this time, the bottom of the dustproof net 21 abuts against the lower plate 23, blocking the spray hole. After each 30-minute cutting, the cleaning brush 13 is automatically started to run for 2 cycles to clean the surface of the dustproof net 21, so that the powder generated by the cutting machine body 1 during use is blocked by the dustproof net 21. At the same time, the cleaning brush 13 prevents the mesh from being blocked and affecting the spraying of water from the spray hole. Before using the cutting machine body 1, hold the magnetic frame 5 and unfold the waterproof cover 4 upwards, so that the magnetic frame 5 is attracted and fixed to the top magnetic plate 9, so that the waterproof cover 4 covers the groove 3 after unfolding, preventing water stains from spraying to the outside.

[0033] This utility model protects the spray holes on the water storage pipe 6 from dust by setting a dustproof net 21, and at the same time cleans them in time by using a cleaning brush 13 to avoid affecting the water spraying effect. It can also extend the waterproof cover 4 to cover the area around the groove 3 and prevent water stains from spraying to the surrounding area.

[0034] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
