Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a CNC machine tool water circulation filtration device. Background Technology

[0002] During high-precision machining operations using CNC machine tools, a large amount of heat is generated by the cutting tools and workpieces. High temperatures not only accelerate tool wear but may also cause thermal deformation of the workpieces. Cold water is often used to quickly remove the heat generated during machining, thereby improving machining efficiency and quality. At the same time, during the cooling process, a water circulation and filtration device is used to recycle and reuse the cold water.

[0003] Currently, existing CNC machine tool water circulation filtration devices typically use electromagnets to adsorb and filter metal debris in cold water. However, during the actual adsorption and filtration process, the cold water flow rate is too fast, which can easily cause some metal debris to be carried away by the water flow and escape the adsorption range of the electromagnet. This results in the metal debris not being completely removed and also directly reduces the adsorption and filtration efficiency of the electromagnet for metal debris. Therefore, a CNC machine tool water circulation filtration device is proposed to address the above problems. Utility Model Content

[0004] In view of the aforementioned problems, this application proposes a CNC machine tool water circulation filtration device to solve the problem mentioned in the background art that, during use, some metal debris may be carried away by the water flow due to the excessively fast flow rate of cold water and escape the adsorption range of the electromagnet.

[0005] This application provides a CNC machine tool water circulation filtration device, including a water circulation recovery tank. The water circulation recovery tank has a front buckle plate at the top front end and a pull-out magnetic drawer at the rear.

[0006] The magnetic drawer box has a first inclined platform fixed on the left and right sides inside; the first inclined platform has a first electromagnet on its inclined surface.

[0007] A second inclined platform is connected between the two first inclined platforms; the second inclined platform has a second electromagnet on its inclined surface.

[0008] The water circulation recovery tank has a slow-flow upright frame fixed inside and above, with a flow distribution platform on the inside and flow-blocking plates on both sides.

[0009] Preferably, oil-absorbing cotton is engaged between the second inclined platforms.

[0010] Preferably, the flow-blocking plate is an inclined plate symmetrically distributed on the upper left and right sides of the flow-slowing frame.

[0011] Preferably, the water circulation recovery tank has a recovery inlet at the top center, and the outlet of the recovery inlet is directly opposite the middle tip of the diversion platform. The diversion platform has an isosceles triangular shape.

[0012] Preferably, the bottom left and right sides of the water recycling tank are fixedly connected to bases, and a circulating water pipe is connected to the lower right position of the water recycling tank.

[0013] Preferably, an inner bracket is fixedly connected to the upper left and upper right sides of the water recycling tank, and an extension plate is fixedly connected to the lower side of the opposite side of the two inner brackets. The top surface of the extension plate and the bottom surface of the magnetic drawer are fitted together. The distance between the two inner brackets is equal to the length of the magnetic drawer. The magnetic drawer and the water recycling tank are slidably connected.

[0014] Preferably, the front end face of the front buckle plate is fixedly installed with a power terminal. There are two sets of power terminals, each consisting of two terminals. The two sets of power terminals are electrically connected to the first electromagnet and the second electromagnet, respectively. The second electromagnet and the first electromagnet form an upper and lower stepped structure. The flow-blocking plate has an "L" shaped structure and is located directly above the first electromagnet.

[0015] This application has the following advantages:

[0016] In the embodiments of this application, the magnetic suction box, front buckle plate, first inclined platform, first electromagnet, second inclined platform, second electromagnet, and power terminal are provided to facilitate the CNC machine tool water circulation filtration device in the process of adsorbing and filtering metal debris in cold water by electromagnets. First, the slow flow structure composed of a slow flow frame, a flow divider, and a flow baffle plate is used to slow down the flow of cold water with excessive speed. Then, the multi-stage electromagnetic adsorption filtration structure composed of the magnetic suction box, front buckle plate, first inclined platform, first electromagnet, second inclined platform, second electromagnet, and power terminal is used to perform multi-stage adsorption and filtration of metal debris in cold water. This avoids some metal debris from escaping the adsorption range of the electromagnet due to the water flow, resulting in the metal debris not being completely removed, and fully improves the adsorption and filtration efficiency of the device using electromagnets for metal debris.

[0023] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] Reference Figures 1 to 4 This paper illustrates a CNC machine tool water circulation filtration device according to an embodiment of this application, including a water circulation recovery tank 1. A front retaining plate 3 is located above the front end of the water circulation recovery tank 1, and a pull-out magnetic suction box 2 is located at the rear. First inclined platforms 4 are fixed to the left and right sides inside the magnetic suction box 2. First electromagnets 5 are provided on the inclined surfaces of the first inclined platforms 4. A second inclined platform 6 is connected between the two first inclined platforms 4. A second electromagnet 7 is provided on the inclined surfaces of the second inclined platform 6. A flow-slowing frame 9 is fixed to the upper part of the water circulation recovery tank 1, with a flow-diverting platform 10 on its inner side and flow-blocking plates 11 on both sides. Through the synergistic effect of the stepped electromagnet layout and the flow-slowing structure, the water flow velocity is significantly reduced and the adsorption time of metal debris is extended, solving the problem of debris escape. Furthermore, the dual-electromagnet layered filtration improves the adsorption coverage rate.

[0025] Furthermore, oil-absorbing cotton 8 is engaged and connected between the second inclined platforms 6. The flow-blocking plate 11 is an inclined plate symmetrically distributed on the upper left and right sides of the slow-flow frame 9, that is, at the end position on the flow-dividing platform 10. The oil-absorbing cotton 8 can simultaneously absorb oily impurities (such as cutting fluid residue), and the inclined design of the flow-blocking plate 11 further optimizes the water flow deceleration trajectory and enhances the comprehensiveness of filtration.

[0026] It should be noted that the magnetic suction box 2 mentioned above can be equipped with filter holes at the bottom to facilitate filtration during water circulation. Oil-absorbing cotton 8, filter cotton, etc. can be installed at the filter hole position.

[0027] As an example, a CNC machine tool water circulation filtration device includes a water circulation recovery tank 1. A front buckle plate 3 is provided at the upper front end of the water circulation recovery tank 1. A magnetic suction box 2 extending into the water circulation recovery tank 1 is provided behind the front buckle plate 3. First inclined platforms 4 are fixedly connected to the left and right sides of the interior of the magnetic suction box 2. First electromagnets 5 are fixedly installed on the inclined surfaces of the first inclined platforms 4. Second inclined platforms 6, which are disposed inside the magnetic suction box 2, are fixedly connected to the opposite side of the two first inclined platforms 4. Second electromagnets 7 are fixedly installed on the inclined surfaces of the second inclined platforms 6. Oil-absorbing cotton 8 is engaged and connected between the two second inclined platforms 6. A flow-slowing frame 9 is fixedly connected to the middle position of the upper interior of the water circulation recovery tank 1. A flow-diverting platform 10 is fixedly connected to the middle position of the inner side of the flow-slowing frame 9. Flow-blocking plates 11 are fixedly connected to the upper left and upper right sides of the flow-slowing frame 9.

[0028] like Figure 1 and Figure 4As shown, a recovery inlet 17 is located at the top center of the water circulation recovery tank 1. The outlet of the recovery inlet 17 is directly opposite the tip of the diversion platform 10. The diversion platform 10 has an isosceles triangular shape. When the used cold water is sent into the water circulation recovery tank 1 through the recovery inlet 17, the diversion platform 10 will divert the cold water under the connection of the slow-flow frame 9, allowing the cold water to flow to the electromagnet adsorption filtration area. Bases 14 are fixedly connected to the bottom left and right sides of the water circulation recovery tank 1. A circulating water pipe 15 is connected to the lower right of the water circulation recovery tank 1. After the device filters the metal debris and oil in the cold water, the cold water will fall into the lower part of the water circulation recovery tank 1 and then be sent into the water circulation system through the circulating water pipe 15. Water pipes are used to facilitate subsequent recycling. Inner brackets 12 are fixedly connected to the upper left and upper right sides of the water recycling tank 1. Extension plates 13 are fixedly connected to the lower sides of opposite sides of the two inner brackets 12. The top surface of the extension plates 13 and the bottom surface of the magnetic suction box 2 are fitted together vertically. The distance between the two inner brackets 12 is equal to the length of the magnetic suction box 2. The magnetic suction box 2 and the water recycling tank 1 are slidably connected. When periodically cleaning the metal debris attracted to the first electromagnet 5 and the second electromagnet 7, the sliding connection between the magnetic suction box 2 and the water recycling tank 1, supported by the inner brackets 12 and the extension plates 13, facilitates the rapid extraction of the magnetic suction box 2, accelerating the subsequent periodic cleaning of the metal debris.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a power terminal 16 is fixedly installed on the front end face of the front buckle plate 3. There are two sets of power terminals 16, each consisting of two. The two sets of power terminals 16 are electrically connected to the first electromagnet 5 and the second electromagnet 7, respectively. The second electromagnet 7 and the first electromagnet 5 form an upper and lower stepped structure. The flow baffle 11 has an "L" shaped structure and is located directly above the first electromagnet 5. The upper and lower stepped structure formed between the second electromagnet 7 and the first electromagnet 5 facilitates the device to perform multi-stage adsorption and filtration treatment on metal debris in cold water.

[0030] The electrical energy required for the device to start and operate in this utility model comes from an external power source. Specifically, it is necessary to ensure that all four power terminals 16 are connected to the DC power supply system. Before starting the CNC machine tool, the circulating water pipe 15 needs to be connected to the CNC machine tool's water circulation pipeline. It is also necessary to ensure that the recovery inlet 17 is connected to the CNC machine tool's drain end. During high-precision machining operations on the CNC machine tool, when the water circulation filtration device is used to treat the used cold water, the used cold water is sent into the water circulation recovery tank 1 through the recovery inlet 17. The cold water is pre-sent into the slow-flow frame 9, and the diversion table 10 diverts the cold water. When the cold water reaches the inclined end of the diversion table 10, the device will... The flow baffle 11 blocks the flow of cold water that is flowing too fast. Then, the cold water flows to the left and right sides of the magnetic suction box 2. At this time, under the connection of the first inclined platform 4 and the second inclined platform 6, the first electromagnet 5 and the second electromagnet 7 installed inside the magnetic suction box 2 will use the electromagnetic attraction generated after being energized to perform multi-stage adsorption and filtration of metal debris in the cold water. This ensures that the metal debris in the cold water can be fully adsorbed. The separated metal debris will then flow to the middle of the magnetic suction box 2. The oil absorbent cotton 8 will adsorb the oil in the magnetic suction box 2. Finally, the filtered clean cold water will flow to the bottom of the water circulation recovery tank 1, and then flow into the water circulation pipeline through the inside of the circulation water pipe 15 so that the CNC machine tool can circulate the cold water.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.
