Description

Technical Field

[0001] This utility model relates to a magnetic chip removal device and a magnetic chip removal system, belonging to the field of chip processing technology. Background Technology

[0002] When machining various metal workpieces, such as combination machine tools, milling machines, drilling machines and other machining equipment, a large number of metal chips are generated. The metal chips usually enter the cutting fluid pool with the cutting fluid. In order to avoid the metal chips contained in the cutting fluid from damaging the machining equipment, it is necessary to remove the metal chips in the cutting fluid through a chip removal device.

[0003] There are many types of chip removal devices, and magnetic chip conveyors are one of them. Magnetic chip conveyors utilize the magnetic force of a strong magnetic field generated by permanent magnet materials. The working plate is placed above the magnetic material, and the magnetic material, such as a magnetic block, attracts metal chips to the surface of the working plate. As the magnetic block moves to the output side, the metal chips move on the upper surface of the working plate under the attraction of the magnetic force and are output from the output end of the working plate into the chip collection area, thereby separating the metal chips from the cutting fluid.

[0004] Existing magnetic chip conveyors only have the function of adsorbing and conveying chips on the upper surface. The dry conveying process can meet the user's needs. However, when cooling liquid or cooling oil is used to cool the workpiece during processing, small metal chips will be mixed in the cooling medium. Due to the high speed of the cooling medium, the metal chips cannot be well adsorbed onto the work panel. Some small chips will enter the water tank with the cooling medium, causing chip accumulation inside the water tank, which requires regular maintenance. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a magnetic chip removal device and a magnetic chip removal system.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A magnetic chip removal device includes a chip removal housing and a magnetic conveying mechanism disposed in the chip removal housing. The chip removal housing includes an upper working panel. The magnetic conveying mechanism includes a conveying chain, a plurality of magnetic blocks disposed on the conveying chain, and a driving mechanism for driving the conveying chain to rotate. The chip removal housing also includes a lower working panel. The upper working panel is located above the conveying chain, and the lower working panel is located below the conveying chain. The lower working panel is connected to the upper working panel through an end round panel.

[0007] The beneficial effects of this invention are as follows: When the cutting fluid enters the magnetic chip removal device, most of the metal chips, especially heavy chips, can be quickly attracted to the upper working panel by the magnetic blocks. After being attracted by the magnetic blocks, the chips are discharged along the direction of the upper working panel under the action of the conveyor chain. A small portion of metal chips, such as light chips, will flow with the liquid. During the flow, the light chips will gradually settle. These chips can be attracted to the lower working panel by the magnetic blocks and move with them. The chips enter the end round panel, and then move to the upper working panel until they are discharged under the attraction of the magnetic blocks. This invention has a simple structure and adopts a double-sided working mode with upper and lower working panels. Both the upper and lower working panels and the end round panel can attract chips, which can effectively extend the time of the liquid in the working area of ​​the magnetic blocks, allowing the chips to be repeatedly attracted and greatly reducing the chip content in the liquid after chip removal.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the chip removal housing includes a horizontal section and a lifting section, the lifting section is inclined, and the upper working panel includes a horizontal panel and an inclined lifting panel.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the design of the lifting section allows most of the liquid in the metal chips to flow back under its own weight during the magnetic adsorption and lifting process, thus reducing the liquid content of the metal chips and increasing the utilization rate of the cutting fluid.

[0011] Furthermore, it also includes a hydrophobic mechanism for hydrophobizing the lifted chips to drain the liquid.

[0012] The beneficial effect of adopting the above-mentioned further solution is that, although the lifting section is set to increase liquid reflux, the chips will still carry liquid. Due to the surface tension of the liquid and the liquid-containing gaps formed by the superposition of chips, liquid will stagnate and more liquid will be carried in. If the viscosity of the oil liquid is high, the chips will stick together and cannot be separated. In this case, when the weight of the accumulated chips is greater than the attraction force of the magnetic block, they will accumulate on the inclined lifting panel, causing the magnetic chip removal device to fail to remove chips normally. Therefore, a hydrophobic mechanism is added, which can act on the chips on the inclined lifting panel, destroy the surface tension of the liquid, and allow the liquid to flow back along the inclined surface, ensuring smooth magnetic chip removal.

[0013] Furthermore, the hydrophobic mechanism includes a hydrophobic needle, which is disposed on the chip removal housing via a hydrophobic plate. The free end of the hydrophobic needle can act on the chips, causing the liquid carried by the chips to flow back into the water tank along the lifting slope of the upper working panel.

[0014] The beneficial effects of adopting the above-mentioned further solution are that by using hydrophobic needles, which act on the lifted chips, excessive resistance is avoided when the chips attracted by the magnetic block pass through. At the same time, the hydrophobic needles can separate the chips, disrupt the surface tension of the liquid, and break the gaps between the stacked chips, so that the liquid carried by the chips can flow back along the inclined plane. In this way, the liquid content of the discharged chips is reduced, the utilization rate of the cutting fluid after chip removal is improved, the amount of waste is reduced, the chips do not accumulate, and the chip removal of the magnetic chip conveyor is smooth.

[0015] Furthermore, the hydrophobic needles are provided in one or more rows, and when there are multiple rows, the hydrophobic needles are arranged at staggered intervals.

[0016] The advantage of adopting the above-mentioned further solution is that the arrangement of the water-repellent pins can be selected according to the actual situation of metal chip processing. The water-repellent pins can be in one row or multiple rows. When there are multiple rows, the water-repellent pins can be arranged at intervals and staggered to reduce the resistance of the water-repellent pins to the chips.

[0017] Furthermore, baffles are provided on the chip removal housings on both sides of the upper working panel, and a liquid inlet area is formed between the two baffles.

[0018] The advantage of adopting the above-mentioned further solution is that the cutting fluid can enter the magnetic chip conveyor for chip removal at the inlet area between the baffles.

[0019] Furthermore, the magnetic block is provided with chamfers.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the chamfer on the magnetic block facilitates the turning of the magnetic block at the end round panel as it moves with the conveyor chain, which can better meet the requirements of the magnetic block at the end round position for adsorption and conveying of chips.

[0021] This utility model also relates to a magnetic chip removal system, including the magnetic chip removal device as described above, and a chip removal water tank. The lower part of the magnetic chip removal device is placed inside the chip removal water tank. A support leg is provided between the magnetic chip removal device and the chip removal water tank. The chip removal water tank is provided with a liquid inlet.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the cutting fluid can enter the magnetic chip removal device through the inlet. The support legs can be on the chip removal housing, or they can be installed on the chip removal water tank, as long as the lower working panel of the magnetic chip removal device can be ensured to work, that is, the chips can run along the lower working panel under the attraction of the magnetic blocks. The chips in the cutting fluid can be attracted to the upper working panel, the lower working panel, and the end round panel, and run with the magnetic blocks, especially the light chips, avoiding the situation where light chips cannot be attracted and discharged in the liquid for a long time. This magnetic chip removal system can be used for the attraction and conveying of sheet-like and block-like chips, and can also be applied to the conveying and discharge of grinding chips.

[0023] Furthermore, the chip removal water tank is equipped with an overflow baffle and a liquid outlet area, allowing the liquid in the chip removal water tank to overflow into the liquid outlet area through the overflow baffle.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the liquid after chip removal treatment can enter the liquid outlet area through overflow, which can further reduce the chip content in the liquid and improve the liquid utilization rate.

[0025] Furthermore, it also includes a secondary water tank, and a liquid passage is provided between the secondary water tank and the chip discharge water tank.

[0026] The beneficial effect of adopting the above-mentioned further solution is that an auxiliary water tank can also be set up. The liquid after chip removal can enter the auxiliary water tank from the chip removal water tank, and then the liquid in the auxiliary water tank can be pumped out for reuse.

[0027] Furthermore, the auxiliary water tank is equipped with multiple auxiliary tank overflow baffles, which divide the auxiliary water tank into multiple sub-tank areas.

[0028] The beneficial effect of adopting the above-mentioned further solution is that the auxiliary water tank can also be divided into multiple areas by the overflow baffle of the auxiliary tank. In this way, the liquid enters the next sub-tank area by overflowing. The overflow can also further reduce the chips in the liquid, further reduce the chip content in the liquid, and improve the utilization rate of the liquid. Attached Figure Description

[0036] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0037] like Figures 1-4 As shown, a magnetic chip removal device includes a chip removal housing 1 and a magnetic conveying mechanism disposed within the chip removal housing 1. The chip removal housing 1 includes an upper working panel 2. The magnetic conveying mechanism includes a conveying chain 6, a plurality of magnetic blocks 5 disposed on the conveying chain 6, and a driving mechanism for driving the conveying chain 6 to rotate. The chip removal housing 1 also includes a lower working panel 3. The upper working panel 2 is located above the conveying chain 6, and the lower working panel 3 is located below the conveying chain 6. The lower working panel 3 is connected to the upper working panel 2 through an end round panel 4.

[0038] The chip removal housing 1 includes a horizontal section and a lifting section, with the lifting section being inclined. The upper working panel 2 includes a horizontal panel 21 and an inclined lifting panel 22. The design of the lifting section allows most of the liquid in the metal chips 8 to flow back under its own weight during the adsorption and lifting process by the magnetic block 5, thus reducing the liquid content of the metal chips 8 and increasing the utilization rate of the cutting fluid. The horizontal panel 21 and the inclined lifting panel 22 have a rounded transition.

[0039] It also includes a hydrophobic mechanism for draining liquid from the lifted chips 8. Although the lifting section is provided to increase liquid return, the chips 8 will still carry liquid. Due to the surface tension of the liquid and the liquid content formed by the superposition of chips, there will be a lot of liquid entrainment. If the oil liquid has high viscosity, the chips 8 may stick together and cannot be separated. In this case, when the weight of the accumulated chips 8 is greater than the attraction force of the magnetic block 5, it will accumulate on the inclined lifting panel 22, causing the magnetic chip removal device to fail to remove chips normally. Therefore, a hydrophobic mechanism is added, which can act on the chips 8 on the inclined lifting panel 22 to break the surface tension of the liquid, so that the liquid can return along the inclined surface and ensure smooth magnetic chip removal.

[0040] The hydrophobic mechanism includes hydrophobic needles 9, which are mounted on the chip conveyor housing 1 via a hydrophobic plate. The free end of the hydrophobic needles 9 can act on the chips 8, causing the liquid carried by the chips 8 to flow back into the water tank along the lifting ramp of the upper working panel 2. By using hydrophobic needles 9, the hydrophobic needles 9 act on the lifted chips 8, preventing excessive resistance when the chips 8 attracted by the magnetic block 5 pass through. At the same time, the hydrophobic needles 9 can separate the chips 8, disrupt the surface tension of the liquid, and reduce the gaps between the stacked chips 8, allowing the liquid carried by the chips 8 to flow back along the ramp. This reduces the liquid content of the discharged chips 8, improves the utilization rate of the cutting fluid after chip removal, reduces the amount of waste material, prevents chip accumulation, and ensures smooth chip removal by the magnetic chip conveyor.

[0041] The hydrophobic pins 9 are arranged in one or more rows. When there are multiple rows, the hydrophobic pins 9 in adjacent rows are staggered. The arrangement of the hydrophobic pins 9 can be selected according to the actual situation of processing metal chips 8. The hydrophobic pins 9 can be in one row or multiple rows. When there are multiple rows, the hydrophobic pins 9 can be arranged at intervals and staggered to reduce the resistance of the hydrophobic pins 9 to the chips 8.

[0042] Baffles 10 are respectively provided on the chip removal housing 1 on both sides of the upper working panel 2, and a fluid inlet area is formed between the two baffles 10. Cutting fluid can enter the magnetic chip conveyor through the fluid inlet area between the baffles 10 for chip removal.

[0043] The magnetic block 5 is provided with a chamfer 51. The chamfer 51 on the magnetic block 5 facilitates the turning of the magnetic block 5 at the end round panel 4 as it runs with the conveyor chain 6, and can better meet the requirements of the magnetic block 5 at the end round panel position for adsorption and conveying of chips 8.

[0044] The drive mechanism includes a drive wheel, a driven wheel, and a drive motor 7. The drive motor 7 is mounted on the chip removal housing 1 and drives the drive wheel to rotate. The conveyor chain 6 is wound around the drive wheel and the driven wheel. The drive motor 7 enables the drive of the conveyor chain 6.

[0045] The output shaft of the drive motor 7 is connected to the drive wheel through a transmission mechanism.

[0046] The transmission mechanism includes a transmission wheel and a transmission belt. The transmission wheel is mounted on the output shaft of the drive motor 7, and the transmission belt is wrapped around the transmission wheel and the drive wheel.

[0047] like Figure 5 and Figure 6As shown, this utility model also relates to a magnetic chip removal system, including the magnetic chip removal device as described above, and a chip removal water tank 12. The lower part of the magnetic chip removal device is placed inside the chip removal water tank 12. A support leg 11 is provided between the magnetic chip removal device and the chip removal water tank 12. An inlet 13 is provided on the chip removal water tank 12.

[0048] The chip removal water tank 12 is equipped with an overflow baffle 14 and a liquid outlet zone 15. The liquid in the chip removal water tank 12 can overflow into the liquid outlet zone 15 through the overflow baffle 14. The liquid that has undergone chip removal treatment then overflows into the liquid outlet zone 15, which can further reduce the content of chips 8 in the liquid and improve the liquid utilization rate.

[0049] It also includes a secondary water tank 17, and a liquid passage 16 is provided between the secondary water tank 17 and the chip removal water tank 12. A secondary water tank 17 can also be provided, allowing the liquid after chip removal to enter the secondary water tank 17 from the chip removal water tank 12, and then the liquid in the secondary water tank 17 can be pumped out for reuse.

[0050] The auxiliary water tank 17 is equipped with multiple auxiliary tank overflow baffles 18, which divide the auxiliary water tank 17 into multiple sub-tank areas 19. The auxiliary water tank 17 can also be divided into multiple areas by separating them with the auxiliary tank overflow baffles 18. In this way, the liquid flows into the next sub-tank area 19 by overflowing. The overflow can also further reduce the amount of chips 8 in the liquid, thereby reducing the chip content in the liquid and improving the utilization rate of the liquid.

[0051] The magnetic chip conveyor is a double-sided working mode with upper and lower sides. The internal magnetic block 5 is equidistant from the upper working panel 2 and the lower working panel 3. The length direction of the magnetic block 5 is chamfered 51 so that it can maintain the working gap with the end round panel 4 when it rotates, and complete the adsorption and conveying of the chip 8 by the upper and lower working panels 3 and the end round panel 4.

[0052] The cutting fluid enters the magnetic chip removal device through the inlet 13. Most of the metal chips 8, especially heavy chips, are quickly attracted to the upper working panel 2 by the magnetic blocks 5. After being attracted by the magnetic blocks 5, the chips 8 are discharged along the direction of the upper working panel 2 under the action of the conveyor chain 6. A small portion of the metal chips 8, such as light chips, will flow with the liquid. During the flow, the light chips will gradually settle. These chips 8 can be attracted to the lower working panel 3 by the magnetic blocks 5 and move with them. The chips 8 enter the end round panel 4, and then move to the upper working panel 2 until they are discharged by the attraction of the magnetic blocks 5. The upper and lower working panels 3 and the end round panel 4 can all attract chips 8, which can effectively prolong the time that the liquid stays in the working area of ​​the magnetic blocks 5 and solve the problem of a small portion of chips 8 not being attracted and discharged for a long time. This magnetic chip removal system can be used for the attraction and conveying of sheet-like and block-like chips, and can also be applied to the conveying and discharge of grinding chips, greatly reducing the chip content in the liquid after chip removal.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
