[0002] The metal CNC machining center is a highly automated machine tool that can precisely control the tool through the CNC system to perform a variety of complex processing operations on metal workpieces. The metal CNC machining center requires a cooling mechanism because during the processing, the high-speed friction between the tool and the metal workpiece will generate a large amount of heat. If it is not cooled in time, the tool temperature will rise sharply, resulting in reduced tool hardness, increased wear, and shortened tool life. At the same time, high temperature will also cause thermal deformation of the workpiece, affecting processing accuracy. The cooling mechanism can effectively reduce the temperature of the processing area, ensure processing quality and tool life, and improve production efficiency.

[0003] In the prior art, the cooling mechanism of a metal CNC machining center usually uses coolant to cool the tool or metal workpiece. However, due to the high-speed cutting of the tool and metal in the metal CNC machining center, a large amount of debris is generated. The mixing of these debris and the coolant increases the impurities in the coolant. The existing cooling mechanism of a metal CNC machining center usually uses a filter to filter the used coolant. However, since the debris is relatively small and numerous, it is easy to clog the filter, resulting in poor coolant circulation and affecting the cooling effect. Utility Model Content

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figure 1-Figure 5As shown, the utility model provides a cooling mechanism for a metal CNC machining center, including a CNC machining table 1, the bottom of the CNC machining table 1 is fixedly connected to a filter box 2, the inner surface wall of the filter box 2 is fixedly connected to two fixed rods 3, the outer surfaces of the two fixed rods 3 are movably sleeved with a group of springs 4, a movable frame 5 is movably sleeved between the outer surfaces of the two fixed rods 3, the inner surface wall of the movable frame 5 is fixedly connected to a filter screen 6, one side of the outer wall of the movable frame 5 is fixedly connected to a linkage seat 7, the inner movably sleeve of the linkage seat 7 is provided with a connecting rod 8, the inner surface wall of the connecting rod 8 is movably inserted with a linkage rod 9, one side of the outer wall of the linkage rod 9 is fixedly connected to a rotating disk 10, the inner surface wall of the rotating disk 10 is fixedly inserted with a driving motor 11, one side of the outer wall of the filter box 2 is provided with an embedding groove 12, the inner surface wall of the embedding groove 12 is movably inserted with a collection cabinet 13, and one side of the outer wall of the collection cabinet 13 is fixedly connected with a handle 14.

[0025] The effect achieved by the entire embodiment 1 is that the used coolant first flows into the interior of the filter box 2 through the inclined design of the inner wall of the CNC machining table 1, and the coolant containing debris first touches the top of the filter screen 6. At this time, the filter screen 6 plays its filtering role and separates the debris from the coolant. At the same time, the drive motor 11 is started, and its output end drives the rotating disk 10 to rotate. Since the outer wall of the rotating disk 10 is fixedly connected to the linkage rod 9, and the outer wall of the linkage rod 9 is movably sleeved with a connecting rod 8, the rotational motion of the rotating disk 10 is converted into the reciprocating motion of the connecting rod 8, and then through the linkage of the linkage seat 7. , the connecting rod 8 drives the movable frame 5 and the filter screen 6 to perform reciprocating motion together, and in this process the movable frame 5 will squeeze the two sets of springs 4. The two sets of springs 4 provide continuous vibration power for the filter screen 6 through their own elastic deformation, so that the debris on the top of the filter screen 6 is constantly shaken and slides along the inclined surface of the filter screen 6 into the collection cabinet 13. This method not only achieves the effective separation of debris, but also prevents the debris from clogging the filter screen 6, ensuring the smooth circulation of the coolant. Finally, by pulling the handle 14, the collection cabinet 13 can be easily moved out of the filter box 2, which is convenient for cleaning the debris.

[0026] Example 2, as Figure 2-Figure 5As shown, the output end of the filter box 2 is fixedly connected to a water outlet pipe 15, the output end of the water outlet pipe 15 is fixedly connected to a first water pump 16, the output end of the first water pump 16 is fixedly connected to a delivery pipe 17, the output end of the delivery pipe 17 is fixedly connected to a spray pipe 18, the outer wall of the spray pipe 18 is fixedly connected to a group of first nozzles 19, the outer wall of the delivery pipe 17 is fixedly sleeved with a cooling box 20, and one side of the outer wall of the CNC machining table 1 is fixedly connected to one side of the outer wall of the cooling box 20, two air intake fans 21 are fixedly inserted into the inner wall of the cooling box 20, two exhaust fans 22 are fixedly inserted into the inner wall of the cooling box 20, a packing layer 23 is fixedly connected to the inner wall of the cooling box 20, the delivery end of the cooling box 20 is fixedly connected to a water supply pipe 24, the delivery end of the water supply pipe 24 is fixedly connected to a second water pump 25, the delivery end of the second water pump 25 is fixedly connected to a connecting hose 26, and the delivery end of the connecting hose 26 is fixedly connected to a second nozzle 27.

[0027] The effect achieved by the entire embodiment 2 is that the filtered coolant falls into the interior of the filter box 2, and the first water pump 16 is started at this time. The first water pump 16 is started to extract the coolant inside the filter box 2 and pressurize it. The pressurized coolant flows smoothly to the spray pipe 18 through the delivery pipe 17, and then under the uniform distribution of a group of first nozzles 19, the coolant is sprayed downward in the form of atomization to form a fine water mist. At the same time, two air intake fans 21 and two exhaust fans 22 are started. After the air intake fan 21 is started, fresh cold air from the outside is sucked into the cooling box 20; and after the exhaust fan 22 is started, an outward airflow is generated, so that a negative pressure environment is formed inside the cooling box 20. Such a negative pressure environment promotes the cold air to enter the cooling box The water mist flows from bottom to top inside 20, and fully exchanges heat with the coolant mist sprayed from a group of first nozzles 19. This heat exchange is based on the principles of heat conduction and convection, and dissipates heat for the used coolant, thereby absorbing and taking away a large amount of heat, and effectively dissipating heat for the used coolant. In addition, a filler layer 23 is fixedly connected to the inside of the cooling box 20. The filler layer 23 is made of porous ceramic material, which can further increase the contact area between the air and the water mist, improve the heat exchange efficiency, and thus better promote the heat dissipation effect of the coolant. In this way, the coolant can be recycled and its cooling efficiency can be significantly improved, which not only reduces the waste of coolant, but also reduces the operating cost of the equipment.

[0028] Working principle: When in use, the coolant first flows naturally into the filter box 2 through the inner wall slope of the CNC machining table 1. The coolant first passes through the filter screen 6 for preliminary filtration. At this time, the drive motor 11 is started, and its output end drives the rotating disk 10 to start rotating. Since one side of the outer wall of the rotating disk 10 is fixedly connected to the linkage rod 9, and the outer wall of the linkage rod 9 is movably sleeved with a connecting rod 8, the rotational motion of the rotating disk 10 is effectively converted into the reciprocating motion of the connecting rod 8. This motion is transmitted through the linkage seat 7, further driving the movable frame 5 and the filter screen 6. The filter 6 is subjected to reciprocating motion. At the same time, the two sets of springs 4 provide continuous vibration energy to the filter 6 through their elastic action, so that the debris on the top of the filter 6 is constantly shaken and smoothly falls into the collection cabinet 13 below along its inclined surface. This method not only realizes the effective separation of debris, but also significantly reduces the risk of the filter 6 being blocked. The coolant after preliminary filtration falls to the bottom of the filter box 2. At this time, the first water pump 16 is started, and the first water pump 16 extracts the coolant inside the filter box 2 and pressurizes it. The pressurized coolant is transported to the spray pipe through the delivery pipe 17. 18. Under the action of a set of first nozzles 19, the coolant is sprayed downward in the form of mist. At the same time, the staff starts two air intake fans 21 and two exhaust fans 22. After the two air intake fans 21 are started, they suck in the cold air from the outside and send it into the cooling box 20, while the two exhaust fans 22 generate an outward airflow, so that a negative pressure environment is formed inside the cooling box 20. This negative pressure effect causes the cold air to flow from bottom to top inside the cooling box 20, and fully exchange heat with the coolant droplets sprayed by the first nozzles 19. This heat exchange process is based on heat conduction and convection. The principle of heat dissipation is used to effectively dissipate the heat of the used coolant, and a filler layer 23 is fixedly connected to the interior of the cooling box 20. The filler layer 23 is made of porous material and has a large specific surface area and porosity, which can further increase the contact area between the coolant droplets and the cold air, thereby improving the heat dissipation efficiency. In this way, the coolant is effectively filtered and heat dissipated during the recycling process, thereby ensuring its long-term stability and service life. In addition, this method realizes the recycling of the coolant and reduces the risk of resource waste and environmental pollution.
