[0024] like Figure 1 to Figure 7As shown, it shows a metal workpiece wire cutting device in one embodiment of the present disclosure, including a workbench 1, a bottom side of the workbench 1 has a drain port 101, the drain port 101 is used for discharging coolant, and the coolant contains impurities; a mounting plate 2 is arranged on one side of the workbench 1, below the drain port 101; a switching frame 3 is rotatably arranged on the mounting plate 2, and the switching frame 3 has a plurality of mounting portions 301; a plurality of filter units 4 are respectively arranged on a plurality of mounting portions 301, and the filter units 4 are used for filtering impurities in the coolant; the switching frame 3 is arranged so that after rotation, the plurality of filter units 4 are sequentially connected to the drain port 101.

[0025] For example, Figure 1 As shown, in order to solve the technical problems in the prior art that the process of replacing the coolant filter unit of the wire cutting device is complicated, the downtime is long, and the work efficiency is low. A wire cutting device for metal workpieces is designed. A drain port 101 is provided on one side of the bottom surface of the workbench 1 for discharging the coolant containing impurities. The mounting plate 2 is fixed to one side of the workbench 1 and is located below the drain port 101, serving to support the switching frame 3. The switching frame 3 is rotatably connected to the mounting plate 2, and a plurality of mounting parts 301 are distributed on it. A plurality of filter units 4 are respectively mounted on these mounting parts 301, which are used to filter the coolant, and can effectively intercept impurities in the coolant.

[0026] Specifically, before the wire cutting device is started, the switching frame 3 connects one of the filter units 4 with the drain port 101. During operation, the coolant flows into the filter unit 4 from the drain port 101 with the impurities generated by cutting. After filtering, the coolant can be recycled or further processed. As time goes by, the impurities in the working filter unit 4 increase and the filtering effect deteriorates. At this time, the switching frame 3 is rotated to connect another filter unit 4 with the drain port 101 to continue filtering the coolant. The replaced filter unit 4 can be cleaned or the filter element can be replaced without affecting the operation of the device. Maintenance operations such as maintenance.

[0027] The advantage is that the replacement process of the coolant filter unit 4 is simplified. The traditional method requires shutting down the equipment and performing complex disassembly and installation, while the present application can complete the replacement by simply rotating the switching frame 3. This greatly reduces the downtime, from the original long downtime to only a short switching time, ensuring the continuous operation of the wire cutting device, effectively improving work efficiency, and reducing the impact of equipment downtime on production progress.

[0028] In some examples, the filter unit 4 includes a mounting cylinder 401, which is arranged on the mounting portion 301, and has a through groove 4011 along the vertical direction, the upper end of the through groove 4011 is a liquid inlet 4012, and the lower end of the through groove 4011 is a liquid outlet 4013, and after the switching frame 3 rotates, the liquid discharge port 101 is sequentially connected with the plurality of liquid inlets 4012; the filter element 402 is vertically slidably arranged in the through groove 4011, and the filter element 402 is used to filter impurities; the filter element 402 is arranged so that after impurities are accumulated, the coolant impacts the filter element 402, So that the filter element 402 slides vertically downward and approaches the liquid outlet 4013; the first elastic member 403 is arranged in the through groove 4011, and the two ends of the first elastic member 403 act on the inner wall of the through groove 4011 and the filter element 402 respectively, and are used to elastically push the filter element 402 to slide vertically upward, so that the filter element 402 approaches the liquid inlet 4012; the clamping mechanism 404 is arranged in the through groove 4011; the clamping mechanism 404 is arranged so that after the filter element 402 contacts the liquid outlet 4013, the clamping mechanism 404 is used to limit the position of the filter element 402 in the through groove 4011.

[0029] In some examples, the filter element 402 has a first slide groove 4021; the mounting tube 401 has a second slide groove 4014, the clamping mechanism 404 includes a first telescopic rod 405, and the first telescopic rod 405 is slidably set in the first slide groove 4021; the seal 406 is slidably set in the second slide groove 4014; the first telescopic rod 405 and the seal 406 are arranged so that after the filter element 402 contacts the liquid outlet 4013, the first telescopic rod 405 extends into the second slide groove 4014 and pushes the seal 406 so that one end of the seal 406 extends out of the second slide groove 4014 and is located on the outer wall of the mounting tube 401.

[0030] In some examples, a metal workpiece wire cutting device also includes a knocking piece 5, which is swingably set on the mounting plate 2; the knocking piece 5 is arranged so that after the switching frame 3 rotates, the filter unit 4 connected to the drain port 101 is close to the knocking piece 5; after the knocking piece 5 swings, it is used to knock the seal 406 to extend out of one end of the second slide groove 4014, so that the seal 406 pushes the first telescopic rod 405, so that the first telescopic rod 405 moves out of the second slide groove 4014.

[0031] For example, Figure 2-5 As shown, the mounting cylinder 401 is mounted on the mounting portion 301 of the switching frame 3, and the through slot 4011 therein penetrates in the vertical direction, with the upper end being the liquid inlet 4012 and the lower end being the liquid outlet 4013. The cross-sectional shape of the through slot 4011 is precisely matched with the shape of the filter element 402, so as to prevent the coolant from flowing out from the gap between the filter element 402 and the wall of the through slot 4011 without being filtered by the filter.

[0032] The filter element 402 can slide freely vertically in the through groove 4011. The first elastic element 403 is a spring and is arranged in the through groove 4011, with one end connected to the inner wall of the through groove 4011 and the other end connected to the filter element 402. It can ensure that the filter element 402 slides up and down smoothly in the through groove 4011, and when there are few impurities, the filter element 402 can be pushed to a position close to the liquid inlet 4012 with sufficient elastic force, and a guide column for the filter element 402 to slide is arranged in the through groove 4011.

[0033] The clamping mechanism 404 is composed of a first telescopic rod 405 that can slide in the first slide groove 4021 and a sealing member 406 that slides in the second slide groove 4014. The front end of the first telescopic rod 405 is hemispherical, and there is an elastic member in the first slide groove 4021 that elastically pushes the first telescopic rod 405, and a matching groove is provided at a corresponding position inside the second slide groove 4014; the sealing member 406 is T-shaped, with a wider head and a rubber sealing pad attached to the outside. The knocking member 5 is installed on the mounting plate 2 through the swinging of the rotating shaft, and its swinging position corresponds to the position of the filter unit 4, ensuring that the protruding end of the sealing member 406 can be accurately knocked.

[0034] Specifically, after the wire cutting device is started, the coolant carries the impurities generated by cutting and flows out from the drain port 101 of the workbench 1 and flows into the liquid inlet 4012 of the mounting tube 401. After the coolant enters the through groove 4011, it directly impacts the filter screen of the filter element 402, and larger particles of impurities are quickly intercepted. As the cutting work continues, the coolant continues to flow, and impurities gradually accumulate on the filter screen, and the downward impact force on the filter element 402 continues to increase. When the impact force exceeds the elastic force of the first elastic member 403, the filter element 402 begins to slide downward in the through groove 4011. During the sliding process, the lower filter screen continues to finely filter the coolant.

[0035] When the filter element 402 slides down to contact the liquid outlet 4013, the first telescopic rod 405 slides into the second slide groove 4014 along the first slide groove 4021 under the push of the elastic member in the first slide groove 4021. At this time, the hemispherical protrusion at the front end of the first telescopic rod 405 is embedded in the groove in the second slide groove 4014 to achieve the clamping positioning. At the same time, the first telescopic rod 405 pushes the sealing element 406 to slide along the second slide groove 4014 toward the outer wall of the installation cylinder 401 until the head of the sealing element 406 extends out of the second slide groove 4014, completing the entire clamping process, so that the filter element 402 stays stably at the bottom of the through groove 4011.

[0036] When the clamping state of the filter element 402 needs to be released, the operator drives the knocking member 5 to swing and accurately knock the protruding end of the sealing member 406. After being knocked, the sealing member 406 moves toward the first slide groove 4021 under the action of the impact force, and uses its own reaction force to push the first telescopic rod 405, so that the first telescopic rod 405 slides out of the second slide groove 4014 along the first slide groove 4021, thereby releasing the clamping restriction on the filter element 402.

[0037] The advantage is that the filter element 402 can automatically and accurately adjust its position according to the accumulation of impurities, without manual intervention, thus reducing labor costs and human operation errors. The design of the clamping mechanism 404 ensures that the filter element 402 can be firmly clamped and positioned when it slides down to the liquid outlet 4013. It prevents impurities on the filter element 402 from being thrown out of the through groove 4011 when the switching frame 3 rotates. The T-shaped structure and rubber sealing gasket of the seal 406 achieve a good sealing effect and prevent coolant leakage. At the same time, it extends out of the outer wall of the mounting cylinder 401 as an intuitive mark, which is convenient for operators to grasp the working status of the filter element 402 in time. The limiting ring of the second slide groove 4014 ensures the normal operation of the seal 406 and prevents it from accidentally sliding out. The setting of the knocking member 5 provides a convenient operation method for releasing the clamping state of the filter element 402, greatly improves the maintainability of the equipment, reduces maintenance time, and ensures efficient operation of the equipment.

[0038] In some examples, a metal workpiece wire cutting device also includes a baffle 6, which is arranged on a switching frame 3, and has a plurality of through holes 601, and the plurality of through holes 601 correspond one-to-one to the upper and lower positions of the filter unit 4; the baffle 6 is arranged so that the switching frame 3 rotates to open or close the drain port 101.

[0039] For example, Figure 4-7 As shown, the baffle 6 is disc-shaped, fixed on the switching frame 3, and rotates synchronously with the switching frame 3. A plurality of through holes 601 are evenly distributed on the baffle 6, and the positions of these through holes 601 correspond to the filter units 4 one by one to ensure that the coolant can pass smoothly.

[0040] When the switching frame 3 rotates, the baffle 6 rotates accordingly. In the process of switching the filter units 4, when a filter unit 4 is required to work, the switching frame 3 is rotated to align the corresponding through hole 601 with the drain port 101, and the coolant can flow unimpeded from the drain port 101 into the filter unit 4. This mainly prevents the coolant from flowing out of the drain port 101 when the filter element 402 is switched. It prevents the unfiltered coolant from being directly discharged.

[0041] In some examples, the workbench 1 has a guide surface 102 , the guide surface 102 has an angle with the horizontal plane, and the guide surface 102 is connected to the drain port 101 ; the side of the guide surface 102 close to the drain port 101 is lower than the other side.

[0042] For example, Figure 2-3 As shown, a guide surface 102 is provided on the surface of the workbench 1. The guide surface 102 is a smooth inclined plane, which forms a specific angle with the horizontal plane. The side of the guide surface 102 close to the drain port 101 is lower to ensure that the coolant can flow smoothly under the action of gravity.

[0043] Specifically, when the wire cutting device is working, the coolant flows on the workbench 1. Due to the inclined design of the guide surface 102, the coolant naturally flows to the drain port 101 along the inclined direction of the guide surface 102 under the action of gravity. No additional power drive is required, thereby realizing automatic drainage of the coolant, improving the discharge efficiency of the coolant, and ensuring the continuous and stable operation of the wire cutting device.

[0044] In some examples, the workbench 1 further has a liquid guiding groove 103 , which is located on a lower side of the guide surface 102 , and the guide surface 102 is connected to the liquid discharge port 101 through the liquid guiding groove 103 .

[0045] For example, Figure 2-3 As shown, a liquid guiding groove 103 is provided on the lower side of the guide surface 102. The liquid guiding groove 103 is in the shape of a long strip, and has a trapezoidal cross section, which is wide at the top and narrow at the bottom, and is conducive to the collection and flow of the coolant. The liquid guiding groove 103 is connected to the guide surface 102 to ensure that the coolant can flow in smoothly. At the same time, the liquid guiding groove 103 is connected to the drain port 101, so that the coolant can flow into the drain port 101 accurately.

[0046] Specifically, the coolant flows from the guide surface 102 into the liquid guiding groove 103 . Due to the slope design of the liquid guiding groove 103 , the coolant quickly gathers in the liquid guiding groove 103 and flows along the liquid guiding groove 103 to the drain port 101 , thereby realizing the rapid flow of the coolant from the workbench 1 to the drain port 101 .

[0047] In some examples, a metal workpiece wire cutting device further includes a cleaning member 7 , which is slidably disposed on the workbench 1 , and is used to clean impurities in the liquid guiding groove 103 from entering the liquid discharge port 101 after sliding.

[0048] For example, Figure 2-3 As shown, the cleaning member 7 is in the shape of a scraper and is mounted on a guide rail on the workbench 1. The guide rail is arranged parallel to the liquid guiding groove 103 to ensure that the cleaning member 7 can accurately slide over the liquid guiding groove 103. The scraper portion of the cleaning member 7 is made of wear-resistant rubber material, and the cleaning member 7 can be retracted to ensure that the cleaning member 7 can continuously contact the liquid guiding groove 103, which can effectively scrape away impurities in the liquid guiding groove 103 without causing damage to the liquid guiding groove 103.

[0049] Specifically, periodically or when there are many impurities in the liquid guiding groove 103, the operator drives the cleaning member 7 to slide on the guide rail through the driving mechanism. The cleaning member 7 moves along the liquid guiding groove 103, and the scraper scrapes up the impurities in the liquid guiding groove 103 and pushes them to the drain port 101, so that the impurities are discharged together with the coolant, and the liquid guiding groove 103 is kept unobstructed. The setting of the cleaning member 7 can clean the impurities in the liquid guiding groove 103 in time, prevent the impurities from accumulating in the liquid guiding groove 103, and ensure the normal function of the liquid guiding groove 103.

[0050] In some examples, a metal workpiece wire cutting device also includes a transmission unit 8, which is used to transmit the rotational power of the switching frame 3 to the sliding power of the cleaning piece 7. The transmission unit 8 includes a rack 801, which is slidably set on the workbench 1, and the cleaning piece 7 is set on the rack 801; the gear 802 is set on the switching frame 3, and the gear 802 is meshed with the rack 801; the gear 802 is arranged so that the switching frame 3 rotates and drives the gear 802 to rotate, so that the rack 801 drives the cleaning piece 7 to slide.

[0051] For example, Figure 2-7 As shown, the transmission unit 8 is composed of a rack 801 and a gear 802. The rack 801 is mounted on the guide rail on the workbench 1 and is connected to the cleaning member 7, and can drive the cleaning member 7 to slide on the guide rail. The gear 802 is mounted on the switching frame 3 and meshes with the rack 801. When the switching frame 3 rotates, the gear 802 rotates accordingly, and through meshing with the rack 801, the rotational power is converted into the linear motion power of the rack 801.

[0052] Specifically, when the switching rack 3 rotates, the gear 802 is driven to rotate. Since the gear 802 is meshed with the rack 801, the rotation of the gear 802 causes the rack 801 to slide on the guide rail, thereby driving the cleaning member 7 fixedly connected to the rack 801 to slide together. While switching the filter unit 4, the liquid guide groove 103 is automatically cleaned without additional operation.

[0053] The advantage is that the design of the transmission unit 8 realizes the linkage between the rotation of the switching frame 3 and the sliding of the cleaning member 7, integrating the two originally independent operations into one action, without the need for an additional power source, simplifying the operation process and structure of the equipment. At the same time, it ensures that when the filter unit 4 is switched, the liquid guide groove 103 can be cleaned in time, further improving the working efficiency and stability of the wire cutting device.

[0054] In some examples, a metal workpiece wire cutting device also includes a positioning unit 9, which is used to locate the position of the metal workpiece. The positioning unit 9 includes a reference plate 901, which is slidably set on the workbench 1; a fixed vertical plate 902 is set on the reference plate 901, and the fixed vertical plate 902 is used to fix the metal workpiece.

[0055] For example, Figure 1 As shown, the positioning unit 9 includes a reference plate 901 slidably disposed on the workbench 1 and a fixed vertical plate 902 vertically fixed on the reference plate 901. The reference plate 901 is connected to the workbench 1 via a guide rail and can move smoothly on the workbench 1. A plurality of adjustable clamping devices are disposed on the fixed vertical plate 902, and the clamping devices can be bolt-type clamping structures or hydraulic clamping structures, which are used to adjust and fix metal workpieces of different sizes.
