[0002] During the operation of wire EDM CNC machine tools, the machining environment is often complex and susceptible to contaminants such as dust. The machining tank, as a critical area for cutting, typically contains oil or coolant for cooling and lubrication during the machining process. However, external dust can easily fall onto the surface of the oil or coolant inside the machining tank, affecting not only its quality but also machining accuracy and quality. This can lead to surface defects and shorten the lifespan of the electrode wire. Therefore, a wire EDM CNC machine tool structure is needed that effectively prevents dust from entering the machining tank without hindering the movement of the machining head. Utility Model Content

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0013] Reference Figures 1-4 A slow wire EDM CNC machine tool with cooling and dust prevention functions includes a machining groove 2 located on the front side of the machine body 1 and a multi-axis movable machining head 3 located on the front side of the machine body 1. A frame 4 is slidably connected to the inner wall of the machining groove 2. A rectangular groove 5 is formed on the inner wall of the frame 4, and a horizontal plate 6 is slidably connected to both sides of the inner wall of the rectangular groove 5. A first sliding groove 7 is formed on the surface of the horizontal plate 6, and a first slider 8 is slidably connected inside the first sliding groove 7. A mounting plate 9 connected to the machining head 3 is provided on the surface of the first slider 8. A first rotating tube 10 is rotatably connected between the two horizontal plates 6. A second rotating tube 11 is rotatably connected to the front and rear sides of the inner side of the rectangular groove 5, and the surfaces of the first rotating tube 10 and the second rotating tube 11 are respectively wound with... The dustproof cloth 12 connected to the processing head 3 and the horizontal plate 6 can move the frame 4 downwards when the processing head 3 needs to move downwards. There is still a certain distance between the bottom end of the frame 4 and the bottom end of the processing head 3. When the processing head 3 needs to move left and right, it can move left and right inside the first slide groove 7 through the mounting plate 9 and the first slider 8. When the processing head 3 needs to move back and forth, it can move back and forth inside the rectangular groove 5 through the mounting plate 9 and the horizontal plate 6. When the processing head 3 moves, it can also move the corresponding dustproof cloth 12 to be retracted and extended, which can cover the surface of the frame 4 and the top of the processing groove 2 to prevent dust from falling into the surface of the coolant or cooling oil inside the processing groove 2.

[0014] Furthermore, in order to facilitate the automatic winding of the dustproof cloth 12 by the rotating tube, a spring 13 and a fixing rod 14 need to be installed inside the first rotating tube 10 and the second rotating tube 11. Thus, the rotating tube can automatically wind up the dustproof cloth 12 through the action of the spring 13.

[0015] Furthermore, to facilitate the connection between the processing head 3 and the mounting plate 9, a circular plate 15 is provided on the surface of the mounting plate 9, and a rack 16 is provided on the inner wall of the circular plate 15. A gear 17 is connected to the surface of the rack 16, and a threaded rod 18 is fixedly connected to the surface of the gear 17, which is threadedly connected to the mounting plate 9 and the processing head 3. Thus, the circular plate 15 can be rotated, causing the rack 16 on its inner wall to move on the surface of the gear 17, thereby causing the gear 17 to drive the threaded rod 18 to rotate. Since the threaded rod 18 is threadedly connected to the mounting plate 9 and the processing head 3, the threaded rod 18 can rotate and move, allowing it to be turned out from inside the processing head 3, thus enabling its disassembly.

[0016] Furthermore, in order to facilitate the rotation of the threaded rod 18, a second groove 19 is provided at the bottom of the inner side of the circular plate 15, and a second slider 20 is slidably connected inside the second groove 19 and rotatably connected to the bottom of the threaded rod 18. This allows the circular plate 15 to move at the top of the threaded rod 18 through the second groove 19 and the second slider 20, and also facilitates the rotation of the threaded rod 18 on the surface of the second slider 20.

[0017] Furthermore, in order to cool down the processing tank 2, a cooling chamber 21 needs to be set at the bottom of the processing tank 2. A water inlet pipe 22 and a water outlet pipe are respectively set on both sides of the cooling chamber 21. A cooling pipe that contacts the bottom of the processing tank 2 is connected between the water inlet pipe 22 and the water outlet pipe. The cooling pipe has a continuous U-shaped structure. Ventilation pipes 23 are set on both sides of the cooling chamber 21. A cooling fan is installed inside one of the ventilation pipes 23. This is to facilitate the delivery of coolant through the water inlet pipe 22 to the inside of the cooling pipe to cool down the processing tank 2. The coolant is then delivered through the water outlet pipe and circulated through a heat exchanger. The cooling fan cools down the processing tank 2 by air cooling.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
