[0002] Plasma CNC machine tools, also known as CNC plasma cutting machines, are a type of efficient and high-precision metal processing equipment. CNC plasma cutting machines combine computer control and plasma cutting technology to achieve automated, precise and efficient metal cutting operations. Its working principle is mainly to introduce gas (such as compressed air) into the plasma cutting machine to generate a high-temperature plasma arc, use the heat of the arc to partially or locally melt (and evaporate) the metal at the workpiece incision, and use the power of high-speed plasma airflow to remove the molten metal to form an incision. CNC plasma cutting machines are widely used CNC mechanical equipment in contemporary times, especially in the automotive, locomotive, shipbuilding and other industries.

[0003] Although existing plasma CNC machine tools can provide faster cutting speeds, the cut surface may be rough and require subsequent processing to achieve specific surface quality requirements. In addition, the high temperature generated during plasma cutting will cause a certain heat-affected zone on the material. This may cause deformation or performance changes of the material near the cutting area, especially when processing thin plates or sensitive materials.

The design of the extension table 2 expands the use area of ​​the workbench 1, so that components such as the water cooling mechanism can be installed in a wider space;

[0024] The water cooling mechanism includes a water tank 3, a water pipe 1 301, a nozzle 302, a water pump 303, a water collecting tank 5, a water pipe 2 501, a one-way valve 502 and a connecting block 6. The bottom of the water tank 3 is slidably connected to the inside of the chute 1 201 on the left side of the workbench 1, the water collecting tank 5 is slidably connected to the inside of the chute 1 201 on the right side of the workbench 1, and the water pump 303 is connected to the inside of the water tank 3. The water pump 303 drives water from the water tank 3 to flow to the nozzle 302 through the water pipe 1 301 to achieve uniform cooling of the workpiece. Multiple nozzles 302 arranged at equal distances ensure that the cooling water can cover the entire surface of the workpiece, thereby improving the cooling effect. One end of the water pipe 1 301 is fixedly connected to the water outlet of the water pump 303, and the other end of the water pipe 1 301 is fixedly connected to the left side of the water collecting tank 5. The nozzle 302 is arranged below the water pipe 1 301, and there are multiple nozzles 302 that are fixedly connected below the water pipe 1 301 at equal distances. One end of the second water pipe 501 is fixedly connected to the left side of the water collecting tank 5, and the other end of the second water pipe 501 is fixedly connected to the right side of the water tank 3-. The first water pipe 301 and the second water pipe 501 are arranged front and back. The one-way valve 502 is set inside the second water pipe 501. The water collecting tank 5 and the second water pipe 501 are used to recycle cooling water, and the one-way valve 502 prevents water from flowing back, so as to realize the recycling of cooling water. One end of the connecting block 6 is fixedly connected to the side of the water tank 3 and the water collecting tank 5 that are close to each other, and the other end of the connecting block 6 is fixedly connected to the bracket 103.

[0025] Support blocks 801 are fixedly connected on both sides of the workbench 1, and the support blocks 801 provide support for the filter screen 802 to ensure its stability during work. The filter screen 802 is overlapped on the upper surface of the support block 801, and the filter screen is overlapped on the support block 801, which is convenient for installation and disassembly, and easy to clean and replace. The filter screen 802 consists of a wooden frame and a filter screen. Drain grooves 102 are provided on both sides of the upper surface of the workbench 1, and a drain port 104 is provided on the back of the workbench 1.

[0026] Working principle: Place the workpiece to be cut on the workbench 1 and clamp it. The CNC system controls the plasma power supply to generate a high-temperature plasma arc. When the plasma arc contacts the workpiece, it partially melts the workpiece material, thereby achieving cutting. During cutting, the cooling mechanism starts to work, and the water pump 303 draws cooling water from the water tank 3 and transports it to the nozzle 302 through the water pipe 1 301. The nozzle 320 sprays water evenly on the workpiece and the tool to achieve a cooling effect. The excess cooling water then flows into the water collecting tank 5 through the water pipe 1 301, and then enters the water tank 3 through the water pipe 2 501 to achieve recycling. The one-way valve 502 prevents the cooling water from flowing back. The drainage grooves 102 opened on both sides of the upper surface of the workbench 1 and the drainage port 104 opened on the back are the key to keeping the working area clean and dry. During the cutting process, some liquids may be generated, such as coolant or cleaning fluid. These liquids can be quickly directed to the drain port 104 through the drain groove 102 and discharged from the back of the workbench, thereby effectively preventing the liquid from accumulating on the workbench and keeping the work area clean and dry. The design of the filter screen 802 takes into account the convenience of cleaning and replacement. It is overlapped on the upper surface of the support block 801. This overlap method is not only simple and quick, but also makes the filter screen 802 easy to disassemble and install.
