Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, specifically to a self-controlled cooling device for CNC machining centers. Background Technology

[0002] Numerical control (CNC) machining refers to a process of machining parts on CNC machine tools. While the overall process specifications of CNC machining are consistent with those of traditional machine tool machining, significant changes have occurred. It is a machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve problems such as diverse part types, small batches, complex shapes, and high precision, and to achieve efficient and automated machining. CNC machining requires the use of cutting fluid, an industrial liquid used in metal cutting and grinding processes to cool and lubricate tools and workpieces. Cutting fluid is scientifically formulated with various high-performance additives, possessing excellent cooling, lubrication, rust prevention, degreasing and cleaning functions, corrosion prevention, and easy dilution. It overcomes the problems of traditional soap-based emulsions, such as easy odor in summer, difficulty in dilution in winter, and poor rust prevention. It also has no adverse effects on lathe paint and is suitable for cutting and grinding ferrous metals, making it one of the most advanced grinding products currently available. The cutting fluid outperforms saponified oil in all aspects. It has excellent cooling, cleaning, and rust prevention properties, and is non-toxic, odorless, non-corrosive to humans, non-corrosive to equipment, and non-polluting to the environment.

[0003] However, existing CNC machining cutting fluids have the following problems during use: To improve the utilization rate of cutting fluid, the cutting fluid mixed with chips is usually separated and recycled, and the filtered cutting fluid is returned to a recycling tank. The temperature of the recycled cutting fluid is too high, requiring cooling treatment. Existing cutting fluid cooling methods usually use static cooling, which is inefficient. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This utility model provides a technical solution: a self-controlled cooling device for a CNC machining center, comprising a CNC machine tool 1 and a cutting fluid recovery and separation cooling system installed on the CNC machine tool 1. The cutting fluid recovery and separation cooling system includes a storage tank 2, a nozzle 3, an operating table 4, a guide pipe 5, a separation filter box, a water-cooling component, an air-cooling component, a return box, and a return pipe 6. The storage tank 2 is installed on the CNC machine tool 1 and connected to the nozzle 3 through a pipe. The nozzle 3 is installed on the machining end of the CNC machine tool 1. The operating table 4 is located on the CNC machine tool 1 and is used in conjunction with the nozzle 3. The corner of the operating table 4 is connected to the separation filter box through the guide pipe 5. The separation filter box includes a separation box 8 and a filter screen 9 installed in the separation box 8. A drain pipe 10 is installed on the right end of the filter screen 9. The drain pipe 10 is equipped with a valve 11 and a sludge storage container 12 is connected to the lower end. The lower end of the separation filter box is connected to a pump body 13 through a pipe. The water cooling system is connected to a water tank 14 and a cooling plate 15 installed inside the water tank 14. One side of the water tank 14 is connected to an inlet pipe 16 and the other side is connected to a drain pipe 17 to keep the water in the water tank 14 in a flowing state and to guide the water after absorbing heat outward. The outer end of the cooling plate 15 is connected to a return box through a pipe. The return box includes a box body 18 and a sub-box 19 built into the box body 18. A partition 20 is provided in the middle of the sub-box 19. An air duct 21 is formed on the left side of the partition 20 and a spray chamber 22 is formed on the right side. A temperature sensor is provided in the spray chamber 22 to monitor the temperature of the sprayed cutting fluid. If the temperature meets the standard, there is no need to use air cooling. If the temperature is high, secondary air cooling can be selected. A blower 23 is also provided at one end of the air duct 21. One end of the return pipe 6 is connected to the box body 18 and the other end is connected to the liquid storage tank 2. A pump body 13 is also provided on the return pipe 6.

[0020] Further improvements, such as Figure 1 As shown, the surface of the filter screen 9 is formed with several sets of filter holes 24. The filter screen 9 is set at an angle and the height of the left end is greater than the width of the right end. The filter screen 9 separates the chips in the cutting fluid, which is convenient for subsequent recycling and reuse.

[0021] Further improvements, such as Figure 2 As shown, the cooling plate 15 includes a guide plate 25, branch pipes 26, cooling pipes 27, and an outer frame 28. The guide plate 25 is connected to the pump body 13 through pipes. The branch pipes 26 are divided into several groups and evenly installed on the guide plate 25. The branch pipes 26 are connected to the cooling pipes 27. The several groups of cooling pipes 27 are evenly distributed inside the outer frame 28. The ends of the outer frame 28 are fixed to the inner wall of the water tank 14. The cooling pipes 27 are submerged underwater.

[0022] Further improvements, such as Figure 2As shown, the cooling pipe 27 is made of metal and has an overall serpentine structure. This design can extend the flow path of the cutting fluid, thereby improving the cooling effect of the cutting fluid.

[0023] Further improvements, such as Figure 3 As shown, a strainer 29 is installed at the bottom of the spray chamber 22. The strainer 29 has a porous structure and its height is greater than the liquid level in the tank 18, which facilitates the downward leakage of the sprayed cutting fluid.

[0024] Specifically, the surface of the partition 20 is machined with several sets of micro-holes 30. The two ends of the micro-holes 30 are connected to the air duct 21 and the spray chamber 22 respectively. The diameter of the micro-holes 30 is controlled between 1mm and 3mm, which is used to draw out the hot air from the spray chamber 22. This design method will only carry out a very small amount of cutting fluid when the hot air is guided out, thus reducing consumption.

[0025] In use: The workpiece to be processed is placed on the operating table 4, and the workpiece is processed by the cutting head of the CNC machine tool 1. During the processing, the cutting fluid is guided to the processing area through the spray pipe 3 to cool the workpiece and the cutting head. The cutting fluid is guided through the liquid guide pipe 5 and introduced into the separation filter box. The chips in the cutting fluid are separated through the filter screen 9. The separated dirt is introduced into the waste storage container 12 through the drain pipe 10. The filtered cutting fluid enters the bottom of the separation box 8 and is drawn out by the pump body 13 and introduced into the cooling plate 15. The cutting fluid enters the cooling pipe 27 through the branch pipe 26. During the flow in the cooling pipe 27, the water absorbs the heat of the cutting fluid to achieve the purpose of cooling. The cooled cutting fluid is introduced into the spray chamber 22. According to the temperature of the cutting fluid, the operator can choose to turn on the blower 23 to make the airflow in the air duct 21 flow. During the flow, the hot air in the spray chamber 22 is guided out to achieve the purpose of secondary cooling.
