[0005] 2. Some solutions design replaceable filter screens (such as CN220408074U), but manual maintenance is required when the filter resistance rises, which cannot meet the requirements of high-speed continuous processing. Therefore, the existing technology cannot realize high-quality separation of copper processing machine tool oil chip mixture under the premise of ensuring high efficiency, continuity and non-clogging.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0028] Embodiment one

[0029] Please refer to Figures 1-8 The utility model provides a kind of technical scheme: a kind of oil chip separation device for copper processing machine tool, including box 1, box 1 includes oil inlet and oil outlet, the oil body containing metal scrap produced by processing machine tool first from oil inlet into box 1, finally from oil outlet after preliminary filtration and discharge, above belongs to prior art.Box 1 is equipped with filter plate 2 in its interior and is slidably connected with it, the upper portion of filter plate 2 is equipped with multiple baffling components for resisting oil body, multiple baffling components divide the space in box 1 into multiple regions, increase the time of oil body in box 1 by multiple baffling components Circulation, metal scrap in oil body is settled on the upper portion of filter plate 2, to further strengthen the deposition of copper scrap and oil chip separation effect.

[0030] Baffling component includes two baffling plates 4 located on the upper portion of filter plate 2, two baffling plates 4 are fixedly connected, the side surface of two baffling plates 4 is equipped with a baffle 5, baffle 5 is parallel with baffling plate 4, multiple baffles 5 are slidably connected with the inner wall of box 1 by slide rail, the upper portion of oil outlet is equipped with filter screen 17 and is fixedly connected with it, the filter hole of filter screen 17 is smaller than the filter hole on the upper portion of filter plate 2, so that the oil body discharged through oil outlet can further filter small metal impurities, improve oil chip separation. The top of baffle 5 is equipped with connecting rod 6, the other end of connecting rod 6 is located on the upper portion of baffling plate 4, the two ends of connecting rod 6 are fixedly connected with baffle 5 and baffling plate 4 respectively, the region where two baffling plates 4 contact is located directly below oil inlet.The end portion of baffling plate 4 is shaped as inclined, the oil body entering box 1 through oil inlet can be guided to the surface of two baffles 5 by the inclined shape of two baffling plates 4, after being guided through baffle 5, again flow to the central region of box 1, and flow to the middle of two baffling plates 4 arranged equidistantly in rear, carry out next time concentrated to dispersed flowability settlement filtration, until oil body is discharged from oil outlet.

[0031] Further, the bottom of the box 1 is provided with a collection bin 3 for collecting metal debris in the oil body, and a replacement assembly is arranged above the collection bin 3, so that the collection bin 3 can be replaced without stopping the machine. The replacement assembly includes a cover plate 7 arranged above the collection bin 3, and a fixed shaft 8 is arranged in the cover plate 7 and fixedly connected with the cover plate 7. The fixed shaft 8 penetrates through the box 1 and is rotatably connected with the box 1. A knob is arranged on the outer side of the fixed shaft 8 and fixedly connected with the fixed shaft 8. The worker can rotate the fixed shaft 8 and the cover plate 7 by the knob, so that the cover plate 7 is lifted upward, and the metal impurities are allowed to flow into the collection bin 3. When the bottom of the cover plate 7 is in contact with the inner wall of the box 1, the oil body cannot flow into the collection bin 3. The collection bin 3 is slidably connected with the box 1. The bottom of the box 1 is shaped as an inclined surface protruding downward. A plurality of micro-vibrators 16 are arranged on the bottom of the box 1. The micro-vibrators 16 can be M-140. When the filter plate 2 is pulled out (the filter plate 2 is not completely pulled out from the box 1, and the oil body in the box 1 will not leak out), and the cover plate 7 is lifted upward, the bottom of the box 1 can be vibrated by the micro-vibrators 16, so that the debris falling from the filter plate 2 rolls into the collection bin 3 for collection, and the replacement of the filter plate 2 is facilitated.

[0032] Working principle:

[0033] When the oil body containing metal debris flows into the box 1 from the oil inlet, it first impacts the contact area of the two baffles 4 located directly below the oil inlet. Since the end of the baffle 4 is shaped as an inclined surface, the oil body is guided to the surface of the two baffles 5, and then flows to the central area of the box 1 (the oil body discharged from the machining tool has a certain flow rate when it enters the box 1 from the oil inlet, so the oil body can flow through the baffles 4 and 5 and then be discharged from the oil outlet). In this process, the flow direction of the oil body changes multiple times, and the flow speed slows down, so that the metal debris in the oil body begins to settle on the filter plate 2 under the action of gravity.

[0034] As the oil body continues to flow, it will pass through multiple baffling assemblies in turn. Each time the oil body passes through a baffling assembly, the above-mentioned process of concentrating and then dispersing the flow for sedimentation and filtration is repeated. The multiple baffling assemblies divide the space in the box 1 into multiple areas, greatly increasing the flow time of the oil body in the box 1 and further enhancing the sedimentation effect of the metal debris. When the oil body flows to the oil outlet, it will first pass through the filter screen 17. The filter screen 17 has smaller filter holes than the filter holes above the filter plate 2, which can further filter the fine metal impurities and improve the quality of oil debris separation. Finally, the oil body that has undergone preliminary filtration is discharged from the oil outlet.

[0035] In the process of continuous separation of oil body, a large amount of metal debris will gradually accumulate above the filter plate 2. When it is necessary to clean these metal debris, the staff can first rotate the fixed shaft 8 and the shutter 7 by rotating the knob, so that the shutter 7 is lifted upward. At the same time, the filter plate 2 is pulled out a certain distance, but not completely pulled out from the box body 1, so as to prevent the oil body in the box body 1 from leaking out, and then the multiple micro-vibrators 16 at the bottom of the box body 1 are started. The vibration generated by the micro-vibrators 16 will make the metal debris on the filter plate 2 roll off to the bottom of the box body 1. Since the bottom of the box body 1 is shaped as a downward convex inclined surface, the metal debris will roll down the inclined surface to the collection bin 3.

[0036] When the collection bin 3 collects full of metal debris, since the collection bin 3 is slidably connected with the box body 1 in a pullable manner, and the collection bin 3 can be replaced without stopping in the state of changing the assembly. The staff only needs to put down the shutter 7, so that the bottom of the shutter 7 is in contact with the inner wall of the bottom of the box body 1, preventing the oil body from continuing to enter the collection bin 3, and then pulling out the full collection bin 3 and replacing it with an empty collection bin 3, so as to ensure that the oil debris separation device can continuously and efficiently operate, meeting the requirements of high-speed continuous processing of copper processing machine tools.

[0037] Based on the above embodiment, embodiment two

[0038] The two baffles 4 are connected by rotating shafts, the two ends of the connecting rod 6 are provided with shafts 9, the two shafts 9 are respectively inserted into the interiors of the baffle 5 and the baffle 4 and are respectively connected with the two, a protrusion 10 is arranged between the two baffles 4, the end of the protrusion 10 is sharp, the bottom of the protrusion 10 is provided with an electric push rod 11 and is fixedly connected with the ejection area of the electric push rod 11, the outside of the electric push rod 11 is provided with a shell 12 and is fixedly connected with the shell 12, the specific model of the electric push rod 11 can be JP4 series, which can work in the oil body for a long time, the bottom of the shell 12 is provided with a connecting plate 13 and is fixedly connected with the connecting plate 13, the two ends of the connecting plate 13 are fixedly connected with the inner wall of the box body 1.

[0039] The sharp area of the protrusion 10 is located directly below the contact area of the two baffles 4. In the process of upward jacking of the electric push rod 11, the sharp part of the protrusion 10 is inserted between the two baffles 4 and presses the two baffles 4 to make them rotate in opposite directions at the same time. The contact area of the two baffles 4 has a mutual magnetic attraction, so after the protrusion 10 resets, the two baffles 4 will reset due to the mutual magnetic attraction between them and will be re-adsorbed together. The inner wall of the box body 1 is provided with a pressure sensor 14 and a flow rate sensor 15, and the pressure sensor 14, the flow rate sensor 15 and the electric push rod 11 are electrically connected with the control center. The specific models of the pressure sensor 14 and the flow rate sensor 15 can be KEYENCE GP-M series and SICK FTS-I100F14A series respectively, which can be used for working in the environment of long-time oil body immersion.

[0040] Working principle:

[0041] When the oil body is flowing normally, the pressure sensor 14 and the flow rate sensor 15 monitor the pressure and flow rate of the oil body in the tank 1 in real time and transmit the data to the control center. When the pressure sensor 14 detects an abnormal increase in pressure in the tank 1 or the flow rate sensor 15 detects a significant increase in oil flow rate, it indicates that the oil debris flow is large at this time, and there may be more metal debris accumulated at the baffle plate 4, affecting the normal flow of the oil body. After receiving these abnormal data, the control center will immediately issue an instruction to the electric push rod 11. After receiving the instruction, the electric push rod 11 begins to rise upward, driving the protruding block 10 to move upward. Since the sharp area of the protruding block 10 is located directly below the contact area of the two baffle plates 4, during the upward movement of the protruding block 10, the sharp part will be inserted between the two baffle plates 4. With the continuous upward movement of the protruding block 10, it will squeeze the two baffle plates 4 to make them rotate in opposite directions at the same time. In this way, the two baffle plates 4 that were originally attracted to each other will be separated, changing the flow path and direction of the oil body. When the oil body passes through the separated baffle plates 4, the flow state will change greatly, and the metal debris accumulated at the baffle plate 4 will be more easily detached from the baffle plate 4 under the action of the change in the flow state of the oil body, and will settle above the filter plate 2, thereby avoiding the problem of blockage at the baffle plate 4 due to the accumulation of metal debris.

[0042] When the pressure sensor 14 detects that the pressure in the tank 1 returns to normal or the flow rate sensor 15 detects that the oil flow rate returns to normal, it indicates that the blockage problem at the baffle plate 4 has been solved. The control center will issue a reset instruction to the electric push rod 11, and the electric push rod 11 will retract downward, and the protruding block 10 will descend and reset. Since the contact area of the two baffle plates 4 has a mutual attraction magnetic force, after the protruding block 10 resets, the two baffle plates 4 will be re-attracted to each other due to the mutual attraction magnetic force between them, returning to the initial state, continuing to guide and filter the oil body, and ensuring that the oil body can continuously and efficiently separate oil debris in the tank 1.

[0043] It is worth noting that during long-term use, the filter screen 17 and the filter plate 2 need to be cleaned and replaced regularly. An observation window can be provided on the tank 1 to facilitate the observation of the use of the filter screen 17 and the filter plate 2 by the staff. At the same time, in order to further improve the effect of oil debris separation, multiple detection points can be set inside the tank 1 to monitor the pressure, flow rate, impurity content and other parameters of the oil body in real time. Through data analysis, the angle of the baffle plate 4, the frequency of the vibrator and other parameters can be adjusted in a timely manner, so that the oil debris separation device is always in the best working state.

[0044] In terms of maintenance, in addition to regular cleaning and replacement of filter screen 17, filter plate 2 and collection bin 3, it is also necessary to check and maintain each component of the device. For example, check the lubrication of the slide rail to ensure that the baffle 5 can slide smoothly; check whether the connecting rod 6 is firmly connected to prevent loosening during work; check the working state of the micro vibrator 16 to ensure that it can vibrate normally, etc. Through regular maintenance and maintenance, problems existing in the device can be found and solved in time, and the normal operation of the device is affected by the damage of the parts.

[0045] In practical application, the oil chip separation device can also be customized according to the needs of different copper processing machine tools. For example, adjusting the size of the device, the number and angle of the baffle plate 4, the aperture of the filter screen 17 and the filter plate 2 and other parameters to adapt to the processing speed of different machine tools, the amount of oil chips produced and other requirements, improve the applicability and practicality of the device.
