[0034] Specifically, the cutting plate 3 can well offset the impact force generated by metal particles, and the hydraulic column 4 can move the cutting machine processing part up and down without manual operation. The cutting machine processing parts such as the cutting machine housing 6, the protective shell 9, and the cutting blade 10 are installed on the crossbeam 5 and connected by fixing screws 7 and fixing nuts 8. The cutting machine housing 6 can protect the cutting blade 10 from interference from flying metal particles, dust, etc., and the front end of the first cross bar 13 and the first rotating shaft 14 are rotated around the output end of the rotating motor 12 as the center of the circle. The pulling force generated by the movement of the first rotating shaft 14 pulls the second rotating shaft 16 connected to the front end of the second cross bar 15 backward. Because the protective shell 9 is rotatably connected with the fixing nut 8, when the second rotating shaft 16 moves backward, it will drive the protective shell 9 to rotate with the protective shell 9 and the fixing nut 8 as the center of the circle until the protective shell 9 completely surrounds the bottom of the cutting blade 10, so as to protect the exposed cutting blade 10, while ensuring the cutting quality and efficiency, improving the operation safety and equipment stability, and reducing the probability of personal injury.

[0035] Reference Figure 1 , Figure 3 and Figure 4The circulation device 2 includes a cutting groove 201, a water flow groove 202 is arranged on the outer wall of the cutting plate 3, a water outlet 203 is opened on the right side of the inner bottom wall of the water flow groove 202, the output end of the water outlet 203 is connected with a water outlet pipe 204, the upper and lower ends of the water outlet pipe 204 are provided with a rotary valve 205, a filter 206 is arranged in the middle of the water outlet pipe 204, the output end of the water outlet pipe 204 is connected with a water tank 207, a first water pump 208 is fixedly connected to the left end of the bottom wall of the cutting machine 1, the output end of the first water pump 208 is connected with a first water supply pipe 209, the output end of the first water supply pipe 209 is connected with a three-way valve 210, and the three-way valve 210 is fixedly connected to the middle of the left side of the inner bottom wall of the water flow groove 202;

[0036] Specifically, the water flowing in the water trough 202 can help remove impurities and metal debris remaining on the cutting plate 3. After the impurities are brought into the water outlet 203 through the water source, they are filtered through the filter 206 in the water outlet pipe 204. The treated water can be reused, so that the impurity-free water continues to flow back to the water tank 207. The water in the water tank 207 is then pumped to the three-way valve 210 through the first water supply pipe 209 by the first water pump 208, and then flows into both sides of the water trough 202 from the three-way valve 210 and is cleaned again, thereby improving the water utilization efficiency.

[0037] Reference Figure 1 , Figure 2 and Figure 4 A second water pump 17 is fixedly connected to the front inner side of the bottom wall of the cutting machine 1, and the output end of the second water pump 17 is connected to a second water supply pipe 18, and the input end of the second water supply pipe 18 is connected to the front side of the water tank 207, and the output end of the second water supply pipe 18 is connected to a conversion head 19, and the output end of the conversion head 19 is connected to a hose 20, and the output end of the hose 20 is connected to a nozzle 21, and a support frame 22 is fixedly connected to the front side of the left end of the top wall of the cutting plate 3, and the nozzle 21 is arranged on the top of the support frame 22; the bottom end of the water tank 207 is connected to a drain pipe 27, and a drain valve 28 is arranged in the middle of the drain pipe 27;

[0038] Specifically, the second water pump 17 extracts coolant from the water tank 207 through the second water supply pipe 18. This circulation mechanism can ensure a continuous and stable supply of coolant, which helps to maintain temperature control during the cutting process, reduce tool wear, and improve processing quality. The coolant is accurately sprayed to the cutting area through the hose 20 and the nozzle 21. Since the nozzle 21 is installed on the top of the support frame 22, the position and angle of the nozzle 21 can be adjusted as needed. The continuous supply of coolant and precise spraying can reduce the interruption time required due to tool overheating, thereby improving the working efficiency of the cutting machine. When the water tank 207 needs to be emptied or cleaned, the drain valve 28 can be opened, and the water can be smoothly discharged through the drain pipe 27.

[0039] Reference Figure 2 and Figure 5 A control console 23 is fixedly connected to the middle of the front side of the cutting machine 1, and a plurality of control buttons 24 are fixedly installed on the top wall of the control console 23; a baffle 29 is fixedly connected to the rear side of the top wall of the cutting plate 3, and the baffle 29 is arranged on the rear side of the cutting groove 201; a hexagonal groove 30 is provided in the middle of the left side of the fixing screw 7, and a plurality of loosening grooves 31 are provided on the left side of the fixing screw 7; columns 25 are fixedly connected to the four corners of the bottom wall of the cutting machine 1, and the bottom ends of the plurality of columns 25 are fixedly connected to the anti-slip bottom plate 26;

[0040] Specifically, the design of the console 23 and the control button 24 allows the operator to operate the machine tool conveniently. Through the buttons on the console 23, the operator can complete all necessary operations in a centralized location, thereby improving work efficiency and ensuring the accuracy and consistency of cutting, thereby improving product quality. During the cutting process, especially when cutting metal or other hard materials, chips or sparks may be generated. The baffle 29 can effectively prevent these chips or sparks from splashing onto the operator or other equipment, thereby protecting the safety of the operator and the equipment. The hexagon socket 30 allows the user to easily tighten or loosen the fixing screw 7 using an hexagon socket wrench, which is convenient for installing, disassembling or adjusting the equipment. The loosening slot 31 can tighten or loosen the fixing screw 7 using common materials without tools through two holes. The column 25 connects the bottom wall of the cutting machine 1 with the anti-skid bottom plate 26, thereby increasing the overall stability of the machine tool. This helps prevent the machine tool from moving or tilting due to vibration or external force during operation, thereby ensuring processing accuracy and safety. The anti-skid bottom plate 26 can disperse the weight of the machine tool to a larger ground, thereby reducing the pressure on the ground.

[0041] Working principle: A cutting plate 3 is installed on the inner bottom wall of the cutting machine 1 to prevent metal particles from splashing and causing wear to the equipment when cutting metal. The cutting plate 3 can effectively offset the impact force generated by the metal particles. The hydraulic column 4 can move the cutting machine processing part up and down without manual operation, thereby enhancing the safety during operation. The cutting machine processing parts such as the cutting machine housing 6, the protective shell 9, and the cutting disc 10 are installed on the crossbeam 5 and connected by fixing screws 7 and fixing nuts 8. The cutting machine housing 6 can protect the cutting disc 10 from interference from splashing metal particles, dust, etc., thereby improving the safety of the operation process. A rotating motor 12 is installed on the fixed bracket 11. By rotating the rotating motor 12, the front end of the first cross bar 13 and the first rotating shaft 14 rotate around the output end of the rotating motor 12 as the center of the circle, and the pulling force generated by the movement of the first rotating shaft 14 drives the front end of the second cross bar 15 connected to the The second rotating shaft 16 is pulled backward, and because the protective shell 9 is rotatably connected with the fixing nut 8, when the second rotating shaft 16 moves backward, it will drive the protective shell 9 to rotate with the protective shell 9 and the fixing nut 8 as the center of the circle, until the protective shell 9 completely surrounds the bottom of the cutting blade 10, and the protective shell 9 engaged in the cutting machine housing 6 is turned out. After the processing is completed, the protective shell 9 can protect the cutting blade 10 that is rotated by inertia and exposed to the outside, while ensuring the cutting quality and efficiency, improving the operational safety and equipment stability, and reducing the probability of personal injury. The design of the water flow trough 202 can allow water to flow through the cutting plate 3. The flowing water can help remove impurities and metal debris remaining on the cutting plate 3, keeping its surface clean. After the impurities are brought into the water outlet 203 through the water source, they are filtered through the filter 206 in the water outlet pipe 204, which can effectively remove impurities and particulate matter in the water and ensure the cleanliness of the recovered water. In this way, the treated water can be reused, so that the impurity-free water continues to flow back to the water tank 207, and then the water in the water tank 207 is pumped to the three-way valve 210 through the first water supply pipe 209 by the first water pump 208, and then flows into the two sides of the water flow trough 202 from the three-way valve 210 and is cleaned again, thereby improving the water utilization efficiency. This recycling method can greatly reduce the demand for fresh water sources and reduce production costs, and also help reduce the pressure of wastewater discharge on the environment.
