Technical Field

[0001] This invention relates to the field of test sieve forming technology, and in particular to a rapid forming device and forming process for test sieves. Background Technology

[0002] In the production and processing of test sieves, the cutting and forming of the sieves is a key step. Currently, existing test sieve cutting equipment has some shortcomings in the cutting process. For example, the pressure of the cutting blade may be unevenly distributed during long-term cutting, which can easily lead to uneven edges of the cut sieves, affecting the quality and performance of the sieves. Therefore, this application provides a rapid forming device and forming process for test sieves to meet the requirements. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a rapid forming device and forming process for experimental screens to solve the problem that uneven pressure distribution of the cutting blade during long-term cutting can easily lead to uneven edges of the screen after cutting, which affects the quality and performance of the screen.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A rapid prototyping device for test sieves includes a frame as an integral support structure, a bearing plate for supporting the test sieves, a hydraulic rod for providing power output, and a cutting mold connected to the extended end of the hydraulic rod for cutting the test sieves. The cutting mold includes a pressure transmission plate, on which a first transmission column and a second transmission column are provided. The second transmission column is connected to a slidable slide rod, and a first spring is sleeved on the slide rod. A cutting blade is fixed at one end of the slide rod, and the two ends of the first spring are respectively connected to the cutting blade and the second transmission column. A blocking part, installed on the support plate, is used to block cutting debris. The blocking part includes mounting grooves on both sides of the pressure transmission plate, a first connecting rod is slidably connected in the mounting grooves, sliding plates are provided on both sides of the frame, and one end of the first connecting rod is fixed to the sliding plate.

[0005] Preferably, the support plate is further equipped with a collection component, which is used to block and collect the flying debris when cutting the test sieve. The collection component includes a collection groove, which is opened on the surface of the support plate. A sliding groove is opened on the surface of the support plate. A first slider, a second slider, and a third slider are slidably arranged on the inner wall of the sliding groove.

One end of the second spring is fixed to the collection groove.

[0006] Preferably, the frame is further equipped with a lubrication assembly for lubricating the cutting blade when cutting the test sieve. The lubrication assembly includes a first tank, which is fixedly mounted on the surface of the frame. A first piston is slidably mounted on the inner wall of the first tank. A first air inlet is connected to one side of the first tank. An oil storage tank is fixedly mounted on one side of the frame for storing lubricating oil. A second piston is slidably mounted on the inner wall of the oil storage tank. A first air outlet pipe is connected to the side of the first tank near the oil storage tank. The first air outlet pipe passes through the frame and communicates with the oil storage tank. A conveying pipe is connected to the inner wall of the oil storage tank. Multiple fuel injectors are evenly spaced on the inner wall of the collection tank. The delivery pipe is connected to the multiple fuel injectors. A push rod is fixedly installed on the top of the pressure transmission plate. The push rod is fixed to the first piston. A second tank is fixedly installed on one side of the frame. A third piston is slidably installed on the inner wall of the second tank. A second air inlet is connected to one side of the second tank, and a second air outlet is connected to one side of the second tank. Multiple air jets are installed on the inner wall of the collection tank between the fuel injectors. The second air outlet is connected to the air jets. A downward pressure rod is fixedly installed on the third piston. One end of the downward pressure rod is fixed to the surface of the pressure transmission plate.

[0007] Preferably, the inner wall of the frame is further equipped with a separation component for collecting and separating waste and lubricating oil. The separation component includes a housing, which is fixedly installed on the inner wall of the frame. A first collection box and a second collection box are placed sequentially on the inner wall of the housing. The first collection box is used to collect lubricating oil, and the second collection box is used to collect waste. The side of the collection trough near the first collection box is connected to the first collection box. A first filter screen is slidably installed on the inner wall of the first collection box, and a second filter screen is also fixedly installed on the inner wall of the first collection box. One side of the second filter screen faces the second collection box. A through groove is opened on the side of the frame near the oil storage tank. A second connecting rod is slidably installed in the through groove. One end of the second connecting rod is fixed to the pressure transmission plate, and the other end of the second connecting rod passes through the first collection box through the sliding groove and is fixed to the first filter screen.

[0008] Preferably, the inner wall of the collection trough slopes gradually downwards from the side closest to the push block toward the first collection box.

[0009] Preferably, a door is provided on one side of the box.

[0010] Preferably, both the fuel injector and the jet nozzle are fan-shaped spray nozzles, with the fuel injector having a spray fan angle of 14° and the jet nozzle having a jet fan angle of 15°.

[0011] Preferably, the first piston, the second piston, and the third piston are all made of a composite material of polytetrafluoroethylene and rubber.

[0012] Preferably, the inner walls of the first air inlet, the second air inlet, the first air outlet, and the second air outlet are all equipped with one-way valves.

[0013] This invention also discloses a rapid prototyping process for test sieves, comprising the following steps: S1: First, the test sieve is cut using a cutting mold. During the cutting process, the cutting debris is reduced by the blocking part. S2: When the cut debris enters the collecting component, the debris is collected by the power of the cutting die; S3: During the process of applying cutting force by moving the cutting die up and down, the lubrication component can be driven to work, so that lubricating oil can be added in time when the cutting die performs the cutting operation on the test sieve. S4: The cutting force generated by the up-and-down movement of the cutting die can drive the separation component to separate the collected debris and excess lubricating oil.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting the cutting mold, the pressure is evenly transmitted through the pressure transmission plate, the first transmission column, the second transmission column and the first spring, so that the pressure can be evenly distributed on the cutting blade during each punching. This helps to ensure that the cutting blade is subjected to uniform force when cutting the test sieve, so that the edge of the cut sieve is more neat and smooth, ensuring the cutting quality of the test sieve and improving the accuracy and performance of the sieve. By using the designed blocking part, when the pressure transmission plate presses downward, it causes the sliding plate to contact the bearing plate, forming a relatively enclosed space in the cutting area. This effectively prevents debris from splashing from both sides of the cutting blade, thus avoiding potential injuries to operators from the splashing debris, such as cuts and punctures. This improves the safety of operators during the cutting process, reduces the splashing of debris, and also reduces the scattering of debris in the work area, making the working environment cleaner. This is not only beneficial to the health of operators (avoiding the inhalation of excessive debris, etc.), but also reduces the impact of debris accumulation on equipment operation, such as equipment parts jamming and wear, thus extending the service life of the equipment. By using the set collection component, the cooperation between the protrusion on the cutter and the slider, when the cutter moves, the protrusion pushes the first slider, which in turn drives the second slider, the third slider and the push block to move in sequence. The push block slides in the collection groove and pushes the debris forward, realizing the automatic cleaning of the debris in the collection groove. It eliminates the need for frequent manual cleaning, improves work efficiency and reduces the intensity of manual labor. The inner wall of the collection tank has a certain inclination. With the push of the pusher, the pushed debris can slide down the inclined inner wall into the depth of the collection tank, making it easier to collect and process. This avoids the accumulation of debris in the collection tank, ensuring that the collection tank can continuously and effectively collect debris, and improving the efficiency and effect of debris collection. The force is transmitted between the slider and the pusher, and after the cutting blade finishes cutting and returns to its original position, the second spring restores its deformation and drives each slider to reset, preparing for the next push of debris. The whole process does not require an additional power source, has a simple structure and good linkage, can be reused, and reduces energy consumption and equipment maintenance costs. The lubrication system injects lubricating oil into the contact surface between the cutting blade and the test sieve, effectively reducing friction between them. This minimizes blade wear during long-term, high-frequency cutting operations, keeping the blade sharp and maintaining excellent cutting performance. The hydraulic rod's operation is linked to the lubrication and cleaning functions, creating an automated process. While cutting, it automatically cleans debris and lubricates the blades without manual intervention or additional downtime, saving time and improving overall production efficiency. Timely cleaning of debris adhering to the cutting blades prevents cutting deviations caused by debris residue. Simultaneously, the even injection of lubricating oil makes the cutting process smoother, ensuring high precision in every cut and improving the cutting quality and dimensional accuracy of the test sieve.

Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0020] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0021] like Figures 1-5 As shown, an embodiment of the present invention provides a rapid prototyping device for test sieves, including a frame 1. The frame 1 serves as the overall support structure for the entire device. The frame 1 is made of high-strength material, possessing good rigidity and stability. A support plate 101 is used to support the test sieve; its surface is flat and smooth, ensuring the test sieve maintains a stable position during the cutting process, preventing displacement or deformation, thereby ensuring cutting accuracy. The dimensions of the support plate 101 are designed according to the specifications of common test sieves, adapting to the cutting requirements of sieves of different sizes. A hydraulic rod 2 serves as the power output component of the device, providing power to drive the cutting die 3 to perform the cutting action. The cutting die 3 is connected to the extended end of the hydraulic rod 2. The cutting die 3 includes a pressure transmission plate 301 as an important component for pressure transmission, on which a first... During the cutting process, the pressure of the hydraulic rod 2 first acts on the pressure transmission plate 301, and then is evenly transmitted to the cutting blade 306 through the first transmission column 302 and the second transmission column 303, ensuring the uniform distribution of the pressure for each punch, thereby making the edge of the cut screen neat and improving the quality of the screen. The second transmission column 303 is connected to a sliding rod 304, and the sliding rod 304 is fitted with a first spring 305. One end of the sliding rod 304 is fixed to the cutting blade 306, and the two ends of the first spring 305 are respectively connected to the cutting blade 306 and the second transmission column 303. This structural design gives the cutting blade 306 a certain elastic buffer during the cutting process, which can effectively reduce the impact force during cutting, protect the cutting blade 306 and the test screen, and also help improve the cutting accuracy and quality. like Figures 1-6As shown, the blocking part 4 is installed on the support plate 101 to block cutting debris and prevent it from splashing everywhere. The blocking part 4 includes mounting grooves 401 on both sides of the pressure transmission plate 301. The first connecting rod 402 is slidably connected in the mounting grooves 401. Sliding plates 403 are provided on both sides of the frame 1. One end of the first connecting rod 402 is fixed to the sliding plate 403. During the cutting process, when the pressure transmission plate 301 moves downward, it will drive the first connecting rod 402 and the sliding plate 403 to move downward together and contact the support plate 101, thereby forming a relatively closed space in the cutting area and effectively blocking the splashing of debris. After the cutting is completed, the pressure transmission plate 301 moves upward, and the sliding plate 403 also rises, which facilitates the next screen placement and cutting operation.

[0022] When cutting the test sieve, the winding device on one side of the drive frame 1 is driven to rewind, and then the feeding device on the other side of the drive frame 1 is driven to extend the hydraulic rod 2 to drive the cutting blade 306 to extend, thereby cutting the test sieve. During the stamping process of the cutting mold 3, the pressure is first applied to the transmission plate. Then, with the help of the evenly distributed first transmission column 302, second transmission column 303 and first spring 305, the pressure is evenly transmitted to the pressure transmission plate 301 to ensure that the pressure is evenly distributed during each stamping. When the pressure transmission plate 301 presses downward, it will drive the sliding plate 403 to move downward together until the sliding plate 403 contacts the bearing plate 101. This can effectively reduce the splashing of debris from both sides of the cutting blade 306 during the cutting of the test sieve, and improve the safety and cleanliness of the cutting operation.

[0023] like Figures 1-8As shown, a collection component 5 is also installed on the support plate 101. Specifically, the collection component 5 is used to block and collect the flying debris during the cutting of the test sieve. The collection component 5 includes a collection groove 501, which is opened on the surface of the support plate 101 to collect the flying debris during the cutting of the test sieve. The shape and size of the collection groove 501 are designed according to actual needs, and it can hold a certain amount of debris. Its inner wall is smooth, which facilitates the sliding and collection of debris. A sliding groove 502 is opened on the surface of the support plate 101. A first slider 503, a second slider 504, and a third slider 505 are slidably arranged on the inner wall of the sliding groove 502. The first slider 503 and the second slider 504 and the third slider 505 respectively make contact through the inclined surface between them. This inclined surface contact design enables the transmission and conversion of force between the sliders. A protrusion 506 is fixedly provided on the side of the cutter 306 near the first slider 503. The protrusion 506 contacts the inclined surface of the first slider 503. When the cutter 306 performs the cutting action, the protrusion 506 will contact the inclined surface of the first slider 503 as the cutter 306 moves, thereby pushing the first slider 503 to slide in the sliding groove 502. A pusher 507 is slidably provided on the inner wall of the collection groove 501. The pusher 507 is slidably connected to the inner wall of the collection groove 501. The side of the pusher 507 near the third slider 505 is fixed to the third slider 505, and a second spring 508 is fixedly provided on the side of the pusher 507 near the third slider 505. One end of the second spring 508 is fixed to the collection groove 501. Under the push of the third slider 505, the pusher 507 can slide in the collection groove 501, pushing the collected debris forward for easy centralized processing.

[0024] When the pressure transmission plate 301 drives the cutting blade 306 downward to cut the test sieve, it will simultaneously drive the sliding plate 403 to slide down and make it contact the support plate 101. In this way, a relatively closed small space is formed in the area where the cutting blade 306 cuts the test sieve. During the cutting process, the flying debris generated by the test sieve will be blocked by the sliding plate 403 and fall into the collection tank 501. When the protrusion 506 on the cutting blade 306 contacts the inclined surface of the first slider 503, the first slider 503 will slide along the sliding groove 502 away from the cutting blade 306. During the sliding of the first slider 503, it will squeeze the second slider 504 to move forward. When the second slider 504 slides forward, it will squeeze the third slider 505, thereby pushing the push block 507 to slide forward along the inner wall of the collection groove 501. When the push block 507 slides forward, it will stretch the second spring 508. At the same time, it can push the debris in the collection groove 501 forward. Since the inner wall of the collection groove 501 has a certain inclination, the pushed debris can slide down the inclined inner wall into the depth of the collection groove 501, which is convenient for collection and processing. When the pressure transmission plate 301 drives the cutting blade 306 to complete the cutting of the test sieve and return to its original position, the protrusion 506 on the cutting blade 306 gradually disengages from the first slider 503. At this time, the second spring 508 restores its deformation, driving the third slider 505 to reset. During the reset process, the third slider 505 pushes the second slider 504, thereby causing the first slider 503 to return to its initial position, preparing for the next push of debris.

[0025] like Figures 1-12 As shown, the frame 1 is also equipped with a lubrication assembly 6 for lubricating the cutting blade 306 during the cutting of the test sieve. The lubrication assembly 6 includes a first tank 601, which is fixedly mounted on the surface of the frame 1. A first piston 602 is slidably mounted on the inner wall of the first tank 601. A first air inlet 603 is connected to one side of the first tank 601 for drawing in air to provide the necessary power source for the system. A first air outlet 606 is connected to the side of the first tank 601 near the oil storage tank 604. 6 passes through the frame 1 and is connected to the oil storage tank 604. It is used to transport the gas in the first tank 601 to the oil storage tank 604, thereby promoting the flow of lubricating oil in the oil storage tank 604. The oil storage tank 604 is fixedly installed on one side of the frame 1 for storing lubricating oil. The inner wall of the oil storage tank 604 is slidably provided with a second piston 605. Under the pressure of the gas transported by the first gas outlet pipe 606, the second piston 605 can slide smoothly in the oil storage tank 604, thereby squeezing out the lubricating oil evenly and providing the necessary lubrication for the cutting area. like Figures 1-12 As shown, the inner wall of the oil storage tank 604 is connected to a conveying pipe 607, which is connected to multiple oil nozzles 608. This allows the lubricating oil squeezed out of the oil storage tank 604 to be accurately delivered to the oil nozzles 608, achieving uniform lubrication of the cutting area, effectively reducing the wear of the cutting blade 306, and improving the service life and cutting accuracy of the cutting blade 306. A second tank 610 is fixedly installed on one side of the frame 1. A third piston 611 is slidably installed on the inner wall of the second tank 610. A second air inlet 612 is connected to one side of the second tank 610 to draw in air and provide power to the system. A second air outlet pipe 613 is connected to one side of the second tank 610, which is connected to a jet nozzle 614. This allows the gas in the second tank 610 to be delivered to the jet nozzle 614, achieving cleaning of the cutting area and timely removal of debris generated during the cutting process. like Figures 1-12As shown, a downward pressure rod 615 is fixedly mounted on the third piston 611. One end of the downward pressure rod 615 is fixedly connected to the surface of the pressure transmission plate 301. A top rod 609 is fixedly mounted on the top of the pressure transmission plate 301. The top rod 609 is fixedly connected to the first piston 602. By moving the pressure transmission plate 301 up and down, the downward pressure rod 615 and the top rod 609 are precisely driven to move, thereby controlling the first piston 602 and the third piston 611, and thus driving the lubrication and cleaning functions. The first piston 602, the second piston 605, and the third piston 611 are all made of a composite material of polytetrafluoroethylene and rubber. This material has good sealing performance, low coefficient of friction, excellent chemical stability, good wear resistance, and good... With its advantages of good flexibility and mechanical strength, it can ensure the normal operation of the system, improve operating efficiency, extend service life, and enhance the reliability and safety of the system, ensuring the stable and efficient operation of the lubrication and cleaning system. Furthermore, the inner walls of the first air inlet 603, the second air inlet 612, the first air outlet 606, and the second air outlet 613 are all equipped with one-way valves. These one-way valves ensure that gas flows only in a predetermined direction, effectively preventing backflow and guaranteeing the normal operation and stability of the system. During the air intake process, the one-way valve allows air to smoothly enter the tank; during the air outlet process, the one-way valve prevents gas backflow, ensuring that the gas is accurately delivered to the corresponding components, providing a reliable guarantee for the realization of the lubrication and cleaning functions.

[0026] During the cutting process of the test sieve, the hydraulic rod 2 pushes the pressure transmission plate 301 downward, which drives the cutting blade 306 to cut the test sieve. When the pressure transmission plate 301 slides down, the pressure rod 615 slides down simultaneously, pushing the third piston 611 to move down along the inner wall of the second tank 610. The downward movement of the third piston 611 squeezes the gas in the second tank 610, causing it to enter the second air outlet pipe 613 and be ejected from the air nozzle 614. The ejected gas blows towards the side of the cutting blade 306 that contacts the test sieve, which can effectively remove the debris attached to the cutting blade 306 after cutting, and avoid the debris residue affecting the subsequent cutting quality of the test sieve. When the hydraulic rod 2 drives the pressure transmission plate 301 to complete the cutting and slide upward, the pressure transmission plate 301 pushes the first piston 602 to move upward along the inner wall of the first tank 601 through the top rod 609. The upward movement of the first piston 602 causes the gas in the first tank 601 to enter the first vent pipe 606, and then be transported to the first oil storage tank 604. Under the action of the gas in the first vent pipe 606, the second piston 605 in the first oil storage tank 604 squeezes out the lubricating oil along the inner wall. The lubricating oil reaches the oil nozzle 608 through the delivery pipe 607, thereby lubricating the contact surface between the cutting blade 306 and the test sieve. Furthermore, during the operation of hydraulic rod 2, when the extended drive end extends to drive the cutting blade 306 to cut the test sieve, the downward pressure of the extended hydraulic rod 2 pushes the lowering rod 615, causing the second piston 605 to slide down along the inner wall of the second tank 610, prompting the second vent pipe 613 to release air and remove debris; simultaneously, the extended hydraulic rod 2 pulls the first piston 602 down along the inner wall of the first tank 601, allowing air to enter through the first vent port 603. When hydraulic rod 2 retracts, the second piston 605 slides down along the second tank... The first piston 602 slides up the inner wall of the first tank 601, and under the action of the one-way valve, air enters through the second air inlet 612; the first piston 602 slides up the inner wall of the first tank 601, and under the action of the one-way valve, air exits through the first air outlet 606, realizing the delivery of lubricating oil. This allows the extended end of the driving hydraulic rod 2 to automatically clean the debris on the cutting blade 306 and automatically lubricate the equipment when cutting or retracting the test sieve, effectively improving the working efficiency and stability of the equipment and extending its service life.

[0027] like Figures 1-13 As shown, the inner wall of the frame 1 is also equipped with a separation component 7, which mainly collects and separates waste and lubricating oil. The separation component 7 includes a box 701 fixedly installed on the inner wall of the frame 1. A box door is provided on one side of the box 701 to facilitate the handling of lubricating oil and debris in the box 701 by the staff in subsequent operations. like Figure 13 As shown, a first collection box 702 and a second collection box 703 are placed sequentially on the inner wall of the box 701. The first collection box 702 is mainly used to collect lubricating oil, while the second collection box 703 is responsible for collecting waste debris. The side of the collection trough 501 near the first collection box 702 is connected to the first collection box 702, so that the lubricating oil and waste debris flowing out of the collection trough 501 can smoothly enter the first collection box 702. like Figure 13 As shown, a first filter screen 704 is slidably disposed on the inner wall of the first collection box 702, and a second filter screen 705 is also fixedly disposed thereon. One side of the second filter screen 705 faces the second collection box 703. The first filter screen 704 can initially separate the lubricating oil and waste debris flowing into the first collection box 702 during the sliding process, intercepting larger waste debris particles, while allowing lubricating oil and smaller debris to pass through. The second filter screen 705 further separates the mixture that has passed through the first filter screen 704. Due to its inclined arrangement and one side facing the second collection box 703, the lubricating oil that has undergone initial separation can flow smoothly into the bottom of the first collection box 702 for collection, while the remaining debris will slide down the inclined surface of the second filter screen 705 into the second collection box 703. like Figure 13As shown, a through groove is provided on the side of the frame 1 near the oil storage tank 604. A second connecting rod 706 is slidably arranged in the through groove. One end of the second connecting rod 706 is fixedly connected to the pressure transmission plate 301, and the other end passes through the first collection box 702 through a sliding groove and is fixed to the first filter screen 704. In this way, when the pressure transmission plate 301 moves up and down during the cutting process, it will drive the second connecting rod 706 to move synchronously, thereby causing the first filter screen 704 to slide up and down in the first collection box 702. This up and down sliding can more effectively separate lubricating oil and waste, improve the separation effect, and make the whole separation process more automated, reduce manual intervention, and improve work efficiency.

[0028] When the extended end of the hydraulic rod 2 extends and retracts, it drives the cutting blade 306 to cut the test sieve. The pressure transmission plate 301 slides downward, which in turn drives the second connecting rod 706 to move up and down together. During the downward sliding of the second connecting rod 706, the first filter screen 704 slides up and down along the inner wall of the first collection box 702. This up and down sliding of the first filter screen 704 can effectively separate debris and excess lubricating oil. Multiple up and down sliding operations can make the separation effect of debris and lubricating oil even better. After initial separation by the first filter screen 704, the debris and lubricating oil will reach the second filter screen 705. Since the second filter screen 705 is set at an angle, the debris will flow into the second collection box 703 along the angled mesh surface, while the lubricating oil will also flow into the second collection box 703 through the second filter screen 705. When it is necessary to process the collected lubricating oil and debris, the staff only needs to open the box door and pull out the first collection box 702 and the second collection box 703.

[0029] like Figures 7-13 As shown, the inner wall of the collection tank 501 gradually slopes downwards from the side near the pusher block 507 toward the first collection box 702. This allows the debris pushed by the pusher block 507 to move more smoothly toward the first collection box 702 within the collection tank 501 using gravity, reducing the possibility of debris accumulating or remaining in the collection tank 501. This ensures that debris is efficiently collected to the designated location for subsequent unified processing. The sloped inner wall also prevents debris from clogging during movement. If the inner wall of the collection tank 501 were horizontal, debris would easily accumulate during the pusher block 507's movement, hindering subsequent debris movement. The sloped design allows debris to flow more orderly toward the first collection box 702 under the combined action of gravity and the pusher block 507, reducing the risk of clogging.

[0030] This invention also discloses a rapid prototyping process for test sieves, comprising the following steps: S1: First, the test sieve is cut using the cutting mold 3. During the cutting process, the blocking part 4 reduces the splashing of cutting debris. S2: When the cut debris enters the collecting component 5, the debris is collected by the power of the cutting mold 3; S3: During the process of applying cutting force by moving up and down the cutting mold 3, the lubrication component 6 can be driven to work, so that lubricating oil can be added in time when the cutting mold 3 performs cutting operation on the test sieve. S4: The cutting force generated by the up-and-down movement of the cutting die 3 can drive the separation component 7 to separate the collected debris and excess lubricating oil.
