Description

Technical Field

[0001] This invention belongs to the field of cutting device technology, and more specifically, relates to a stainless steel pipe cutting device. Background Technology

[0002] Steel pipes are steel materials with hollow cross-sections, whose length is much greater than their diameter or circumference. They are classified according to cross-sectional shape into round, square, rectangular, and irregular-shaped steel pipes; according to material into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes, and composite steel pipes; and according to application into steel pipes for transportation pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment, etc.

[0003] Stainless steel pipe cutting is a common processing method, but existing stainless steel pipe cutting equipment still has the following shortcomings in use: 1. Existing equipment mainly relies on manual disassembly and wiping or simple brush cleaning to remove impurities from cutting blades. This is time-consuming and labor-intensive, requiring a 15-30 minute downtime for each cleaning, which affects production continuity. Furthermore, prolonged accumulation of impurities will accelerate blade wear and reduce gear meshing accuracy, thus lowering cutting precision. 2. Most existing equipment only cools the cutting blade during the cutting process, but this method results in a long cooling time after each cut. The long cooling time not only prolongs the processing cycle, but also seriously restricts the continuous production capacity of the equipment. 3. Traditional stainless steel pipe cutting equipment often uses single-specification clamps or universal bolt fastening devices. For irregular cross-sections or high-precision thin-walled pipes, local stress concentration is likely to occur during fixing, leading to pipe deformation. Summary of the Invention

[0007] Preferably, a liquid storage tank is fixedly sleeved on the fixed column, and the liquid storage tank has symmetrically opened second drain ports inside. The two second drain ports are respectively connected to the two first drain ports, and the liquid storage tank is provided with a liquid filling port.

[0008] Preferably, the upper end of the cutting table is symmetrically provided with a first sliding groove and a chip removal groove, the chip removal groove is located between the two first sliding grooves, and a material collection cover is fixedly installed on one side of the cutting table, the material collection cover is directly opposite the chip removal groove.

[0009] Preferably, a connecting frame is slidably inserted inside the material collection hood, and a collection box is fixedly installed at the lower end of the connecting frame. The upper end of the collection box is flush with the lower end of the inner wall of the chip discharge trough.

[0010] Preferably, a vertical plate is fixedly installed at the lower end of the cutting table, a hydraulic cylinder is fixedly installed on the side wall of the vertical plate, and a telescopic rod is installed on the output end of the hydraulic cylinder.

[0011] Preferably, a U-shaped frame is slidably installed inside the first chute, the U-shaped frame is fixedly connected to the telescopic rod, a fixing plate is symmetrically fixedly installed on the upper end of the U-shaped frame, a placement rack is symmetrically fixedly installed on the upper end of the two fixing plates, and a second chute is opened on both fixing plates.

[0012] Preferably, the U-shaped frame has inner grooves on both side walls, and slides are slidably installed inside the two inner grooves and the second slide groove. Fixing strips are fixedly installed on the upper ends of the two slides, and the two fixing strips are respectively located between the two sets of placement frames.

[0013] Preferably, a first spring is fixedly installed at the lower end of each of the two carriages, and the ends of the two first springs away from the two fixing bars are respectively fixedly connected to the inner walls of the two inner grooves.

The two slides are slidably installed on the two screws respectively, and a first threaded ring is threaded onto each of the two screws.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a drive motor, a rotating shaft, a turntable, a wedge block, a slide bar, a third slide groove, a fixed disk, an inner disk, a circular groove, a third spring, and a striking head are provided. When the drive motor is started, the rotating shaft rotates counterclockwise. At this time, the wedge block on the turntable contacts the slide bar, causing the slide bar to slide towards the fixed disk within the third slide groove. The slide bar also synchronously drives the inner disk to move, compressing the second spring on the inner disk. When the wedge block and slide bar become misaligned, the circular groove resets the inner disk and slide bar. During the reciprocating movement of the slide bar, the striking head intermittently contacts and strikes the cutting blade. Under the striking of the striking head, the cutting blade displaces axially on the fixed post, causing the third spring to contract. The striking head generates a high-frequency impact force at the moment of impact, and the rebound process of the third spring is also instantaneous and elastic, which will generate a reverse force on the cutting blade. This reverse force causes the cutting blade to vibrate in the opposite direction, forming a vibration waveform and frequency different from the striking vibration. The superposition of vibrations of different frequencies can cover a wider range of vibration frequencies, and has a better cleaning effect on impurities of different sizes, shapes and adhesion characteristics. This allows the equipment to automatically vibrate and shake off impurities generated by cutting on the cutting blade, realizing automated impurity cleaning of gear cutting blades without manual intervention, avoiding the impact of impurity accumulation on equipment operation, ensuring continuous and efficient operation of the cutting device, reducing equipment downtime for cleaning, and improving overall production efficiency. In this invention, a turntable, wedge blocks, sliders, a first drain port, a third groove, a cutting blade, a storage tank, and a second drain port are provided. When the two sliders located at the bottom slide to the left end inside the third groove, the first drain ports on the two sliders will connect with the second drain port on the storage tank. At this time, the cutting fluid inside the storage tank will flow from the second drain port to the first drain port, and then flow from the first drain port to the cutting blade in a parabolic manner. When the wedge blocks on the turntable contact with the sliders, friction will be generated. Under the action of this friction, the cutting blade will rotate intermittently and slowly. At this time, the cutting fluid can cover the cutting position of the cutting blade, so that the cutting blade can be quickly cooled after one cutting operation. This rapid cooling effect means that the equipment does not need to wait for the cutting blade to cool down for a long time, the single processing cycle time is greatly shortened, and it can be put into the next cutting operation immediately, which greatly improves the production efficiency and meets the needs of large-volume continuous processing. In this invention, when the cutting fluid rapidly cools the cutting blade, the thermal expansion and contraction effect of the metal creates tiny gaps between the attached debris and the surface of the cutting blade. This increases the adhesion of the debris, making it easier for the debris to detach during subsequent hammering, thus improving the peeling efficiency.

[0016] In this invention, a placement frame, fixing bars, a first spring, a screw, a first threaded ring, and a cutting blade are provided. The two ends of the stainless steel pipe to be processed are fixed by the movement of the two fixing bars. As the fixing bars move downward, they will cause the first spring to be compressed, so that the device can fix stainless steel pipes of any size during use. This fixing method can effectively offset the vibration and external force during cutting, prevent the pipe from shifting or deviating during processing, improve processing accuracy, and through the structural design of the two sets of placement frames, after the stainless steel pipe is cut, it can act as a stable support point, effectively preventing the stainless steel pipe from falling due to loss of fixing constraint, reducing material waste and processing safety caused by quality defects. In this invention, a chip removal trough, a collection hood, a collection box, a turntable, a wedge block, an inner disc, a sliding bar, a fixed disc, a fixed column, and a cutting blade are provided. The rotation of the turntable causes the wedge block to rotate, which in turn contacts the sliding bar on the inner disc, causing the sliding bar to rotate as well. The sliding bar then drives the inner disc and the fixed disc to rotate, while the fixed disc drives the fixed column and the cutting blade to rotate. As the stainless steel pipe moves, the cutting process is completed. The waste chips generated during cutting are blown into the chip removal trough and the collection hood, and then fall into the collection box for collection. This equipment achieves automatic feeding and cutting without continuous manual operation, significantly improving cutting efficiency, preventing waste chip splashing, ensuring operator safety, reducing workshop cleaning and maintenance workload, and simultaneously achieving centralized waste chip recycling, thus improving resource utilization.

Detailed Implementation

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0020] Please see Figures 1-10This invention provides a stainless steel pipe cutting device, including a cutting table 11. A fixed frame 33 is fixedly installed on the upper end of the cutting table 11. An extension frame 34 is fixedly installed on the upper end of the fixed frame 33. An inner ring 35 is fixedly installed on the lower end of the extension frame 34. A drive motor 36 is fixedly installed on the side wall of the fixed frame 33. A rotating shaft 37 is installed on the output end of the drive motor 36. The rotating shaft 37 is rotatably installed in the fixed frame 33. A turntable 38 is fixedly installed on the rotating shaft 37. A rubber shock-absorbing pad is fixedly installed between the turntable 38 and the rotating shaft 37. The rubber shock-absorbing pad absorbs the reverse force transmitted to the turntable 38 when the slide bar 45 resets, preventing vibration from being transmitted to the drive motor 36. The turntable 38 has a side wall... Rolling balls 39 are evenly and equidistantly mounted. Wedge blocks 41 are evenly and equidistantly fixed on the end of the turntable 38 away from the rolling balls 39. The slope angle of the wedge blocks 41 is 30°-35°. A polytetrafluoroethylene (PTFE) wear-resistant pad is fixedly installed on the slope surface. The wear-resistant pad reduces the friction between the slider 45 and the wedge blocks 41, preventing the slider 45 from getting stuck and ensuring that the slider 45 smoothly disengages from the wedge blocks 41 to achieve reciprocating motion. An inner plate 42 is provided on one side of the wedge blocks 41. Circular grooves 43 are evenly and equidistantly opened on the side wall of the inner plate 42. A second spring 44 is fixedly installed in the inner wall of each circular groove 43. The second spring 44 is a cylindrical helical spring with a wire diameter of 0.8mm, a mean diameter of 5mm, and 8 effective coils. With a value of k=20N / mm, when the second spring 44 is compressed to 2mm by the wedge block 41, it stores 0.4J of elastic potential energy. When released, it pushes the slider to reset at a speed of 1.2m / s. Slider bars 45 are evenly and equidistantly fixed on the side wall of the inner plate 42. After the stainless steel tube is fixed, the hydraulic cylinder 18 can be activated, and the telescopic rod will begin to extend and retract. The telescopic rod will slide the U-shaped frame 21 to the left inside the first slide groove 12. The U-shaped frame 21 will drive the two fixed plates 22 and the stainless steel tube to move to the left. At this time, the drive motor 36 is activated simultaneously. The drive motor 36 will drive the turntable 38 to rotate clockwise. Under the rotation of the turntable 38, the wedge block 41 will rotate. At this time, the wedge block 41 contacts the slide bar 45 on the inner plate 42, thereby causing the slide bar 45 to rotate. The slide bar 45 then drives the inner plate 42 and the fixed plate 51 to rotate. The fixed plate 51 drives the fixed column 53 and the cutting blade 59 to rotate. When the stainless steel pipe moves, the cutting is completed. The waste generated during the cutting is blown into the chip discharge trough 13 and the collection hood 14, and then falls into the collection box 16 through the chip discharge trough 13 and the collection hood 14 for collection. This equipment realizes automatic feeding and cutting action without continuous manual operation, which greatly improves cutting efficiency, avoids waste splashing, ensures the safety of operators, reduces the workload of workshop cleaning and maintenance, and realizes centralized recycling of waste, improving resource utilization. A striking head 46 is fixedly installed on each of the two upper slide bars 45, and a first drain port 47 is opened on each of the two lower slide bars 45. A fixed plate 51 is fitted on the inner plate 42. A second spring 44 is fixedly connected to the inner wall of the fixed plate 51. A third slide groove 52 is evenly spaced in the inner wall of the fixed plate 51. Each slide bar 45 is slidably installed in each third slide groove 52. A fixed post 53 is fixed on the side wall of the fixed plate 51. A cutting blade 59 is slidably installed on the fixed post 53. The cutting blade 59 is slidably installed along the axial direction of the fixed post 53. A rotating cylinder 54 is fixedly fitted on the fixed post 53. The rotating cylinder 54 is rotatably installed in the inner ring 35. A second threaded ring 55 is threadedly installed on the rotating cylinder 54. A positioning ring 56 is fixedly installed on the second threaded ring 55, and a third spring 58 is fixedly installed on the side wall of the cutting blade 59. The elastic coefficient of the third spring 58 is 15 N / mm. When the striking head 46 strikes the cutting blade 59, the third spring 58 contracts synchronously to buffer the impact force and prevent the reaction force from being transmitted to the fixed post 53. The end of the third spring 58 away from the cutting blade 59 is fixedly connected to the rotating drum 54. After cutting is completed, the second threaded ring 55 can be rotated on the rotating drum 54. The rotation of the second threaded ring 55 will drive the positioning ring 56 to move to the left. At this time, the positioning ring 56 will separate from the cutting blade 59. Then the drive motor 36 can be restarted to make the rotating shaft 37 rotate counterclockwise. At this time, the turntable The wedge block 41 on the 38 will contact the slider 45. At this time, the slider 45 will slide towards the fixed disk 51 inside the third groove 52 under force. The slider 45 will also drive the inner disk 42 to move synchronously. At this time, the second spring 44 on the inner disk 42 will be compressed. When the wedge block 41 and the slider 45 are misaligned, the circular groove 43 will drive the inner disk 42 and the slider 45 to reset. During the reciprocating movement of the slider 45, the striking head 46 will intermittently contact the cutting blade 59 and strike it. Under the striking of the striking head 46, the cutting blade 59 will be displaced in the axial position of the fixed post 53. At this time, the third spring 58 will contract accordingly. The striking head 46 will generate a high-frequency impact force at the moment of striking. The rebound process of the third spring 58 is also instantaneous and elastic, which will generate a reverse force on the cutting blade 59. This reverse force causes the cutting blade 59 to vibrate in the opposite direction, forming a vibration waveform and frequency different from the knocking vibration. The superposition of vibrations of different frequencies can cover a wider range of vibration frequencies, and has a better cleaning effect on impurities of different sizes, shapes and adhesion characteristics. This allows the equipment to automatically vibrate and shake off the impurities generated by cutting on the cutting blade 59, realizing automated impurity cleaning of the gear cutting blade 59 without manual intervention, avoiding the impact of impurity accumulation on equipment operation, ensuring that the cutting device can operate continuously and efficiently, reducing equipment downtime for cleaning, and improving overall production efficiency. A liquid storage tank 61 is fixedly fitted onto the fixed column 53. The liquid storage tank 61 has symmetrically arranged second drain ports 62 inside. The sliding stroke of the slider 45 is 8mm. The elongated first drain port 47 ensures that when the slider 45 slides to the left end, it completely overlaps with the second drain port 62, with the overlap lasting for 0.5s-1s. A nitrile rubber sealing ring is fixedly installed at the contact point between the second drain port 62 and the first drain port 47. The sealing ring ensures a seal when connected, preventing leakage and reducing wear on the slider 45 during sliding. A gas cylinder is fixedly installed on the top of the liquid storage tank 61. The pressure valve operates at a pressure of 0.2MPa-0.3MPa. The liquid level in the reservoir 61 is approximately 10cm-15cm higher than the second drain port 62. The air pressure propels the cutting fluid to flow out rapidly at a flow rate of 20mL / s, discharging 10mL-20mL of cutting fluid within the overlap time. Gravitational potential energy ensures no residue is discharged. The two second drain ports 62 are connected to the two first drain ports 47. The reservoir 61 is equipped with a filling port 63. When the two lower sliding bars 45 slide to the left end inside the third sliding groove 52, the two... The first drain port 47 on the slide bar 45 is connected to the second drain port 62 on the liquid storage tank 61. At this time, the cutting fluid inside the liquid storage tank 61 will flow from the second drain port 62 to the first drain port 47, and then flow from the first drain port 47 in a parabolic direction to the cutting blade 59. When the wedge block 41 on the turntable 38 contacts the slide bar 45, friction will be generated. Under the action of this friction, the cutting blade 59 will rotate intermittently and slowly. At this time, the cutting fluid can cover the cutting position of the cutting blade 59, so that the cutting blade 59 can be quickly cooled after one cutting operation. This rapid cooling effect means that the equipment does not need to wait for the cutting blade 59 to cool down for a long time, and the single processing cycle time is greatly shortened. It can be put into the next cutting operation immediately, greatly improving production efficiency and meeting the needs of large-volume continuous processing. When the cutting fluid rapidly cools the cutting blade 59, the thermal expansion and contraction effect of the metal creates tiny gaps between the attached debris and the surface of the cutting blade 59. This reduces the adhesion of the debris, making it easier for the debris to detach during subsequent tapping, thus improving the peeling efficiency. The upper end of the cutting table 11 is symmetrically provided with a first sliding groove 12 and a chip removal groove 13. The chip removal groove 13 is located between the two first sliding grooves 12. A material collection cover 14 is fixedly installed on one side of the cutting table 11, and the material collection cover 14 is directly opposite the chip removal groove 13. A connecting frame 15 is slidably inserted into the material collection cover 14. A collection box 16 is fixedly installed at the lower end of the connecting frame 15. The upper end of the collection box 16 is flush with the lower end of the inner wall of the chip removal groove 13. A vertical plate 17 is fixedly installed at the lower end of the cutting table 11. A hydraulic cylinder 18 is fixedly installed on the side wall of the vertical plate 17. A telescopic rod is installed on the output end of the hydraulic cylinder 18. A U-shaped frame 21 is slidably installed inside the first sliding groove 12. The U-shaped frame 21 is fixedly connected to the telescopic rod. A fixing plate 22 is symmetrically fixedly installed on the upper end of the U-shaped frame 21. A placement rack 23 is symmetrically fixedly installed on the upper end of each of the two fixing plates 22. A second sliding groove 24 is provided on each of the two fixing plates 22. An inner groove 25 is provided on each of the two side walls of the U-shaped frame 21. A slide frame 26 is slidably installed inside each of the two inner grooves 25 and the second sliding groove 24. A fixing strip 27 is fixedly installed on the upper end of each of the two slide frames 26, and the two fixing strips 27 are respectively located between the two sets of placement racks 23. A first spring 28 is fixedly installed on the lower end of each of the two slide frames 26. The ends of the two first springs 28 furthest from the two fixing strips 27 are respectively connected to… The inner walls of the two inner grooves 25 are fixedly connected. Side blocks 29 are fixedly installed on both sides of the U-shaped frame 21. Screws 31 are fixedly installed on the upper ends of the two side blocks 29. Two slides 26 are slidably installed on the two screws 31 respectively. First threaded rings 32 are threadedly installed on the two screws 31. In use, the stainless steel pipe can be placed on the two sets of placement racks 23 firstly. Then, the position to be cut of the stainless steel pipe can be aligned with the cutting blade 59. Then, the two first threaded rings 32 can be rotated on the two screws 31. The rotation of the two first threaded rings 32 drives the two slides 26 to move downward. At this time, the two slides 26 drive the two fixing bars 27. The device moves downwards, and the two fixing bars 27 fix both ends of the stainless steel pipe to be processed. As the fixing bars 27 move downwards, they also compress the first spring 28, allowing the device to fix stainless steel pipes of any size during use. This fixing method can effectively counteract vibrations and external forces during cutting, prevent the pipe from shifting or deviating during processing, improve processing accuracy, and through the structural design of the two sets of placement racks 23, they can act as stable support points after the stainless steel pipe is cut, effectively preventing the stainless steel pipe from falling due to loss of fixing constraints, reducing material waste and processing safety caused by quality defects.

[0021] Working principle: First, when using the device, place the stainless steel pipe on the two sets of placement racks 23. Then, align the position of the stainless steel pipe to be cut with the cutting blade 59. Next, rotate the two first threaded rings 32 on the two screws 31. The rotation of the two first threaded rings 32 will drive the two slides 26 to move downward. At this time, the two slides 26 will drive the two fixing bars 27 to move downward. The movement of the two fixing bars 27 will fix both ends of the stainless steel pipe to be processed. As the fixing bars 27 move downward, they will compress the first spring 28, so that the device can fix stainless steel pipes of any size during use. This fixing method can effectively offset the vibration and external force during cutting, prevent the pipe from shifting or deviating during processing, improve processing accuracy, and through the structural design of the two sets of placement racks 23, after the stainless steel pipe is cut, it can act as a stable support point, effectively preventing the stainless steel pipe from falling due to loss of fixing constraint, reducing material waste and processing safety caused by quality defects. The second step involves activating the hydraulic cylinder 18. Its output telescopic rod drives the U-shaped frame 21 to slide uniformly to the left along the first slide groove 12 at a speed of 5 mm / s. Simultaneously, the U-shaped frame drives the fixed plate 22 and the fixed stainless steel tube to move towards the cutting blade 59. At the same time, the drive motor 36 is activated, and its speed is adjusted to 1700 r / min. The motor output drives the rotating shaft 37 to rotate synchronously. The rotating shaft, through rubber shock-absorbing pads, drives the turntable 38 to rotate. The wedge-shaped block 41 on the turntable 38 contacts the sliding strip 45 on the inner plate 42, and through friction, drives the inner plate 42 and the fixed plate 51 to rotate together. As the tube rotates, the fixed plate 51 drives the fixed column 53 and the cutting blade 59 to rotate. When the stainless steel tube moves to the cutting blade 59, the rotating cutting blade 59 completes the tube cutting. The waste generated by cutting falls into the collection hood 14 through the chip discharge groove 13 under the action of airflow, and is finally collected into the collection box 16 to realize the centralized recycling of waste. This equipment realizes automatic feeding and cutting action without continuous manual operation, which greatly improves cutting efficiency, avoids waste splashing, ensures the safety of operators, reduces the workload of workshop cleaning and maintenance, and realizes centralized recycling of waste, thereby improving resource utilization. Third, after cutting is completed, rotate the second threaded ring 55 on the rotating drum 54 to move the positioning ring 56 to the left, so that the positioning ring 56 is disengaged from the cutting blade 59. At this time, keep the speed of the drive motor 36 constant, and the turntable 38 continues to drive the wedge block 41 to rotate. When the slope of the wedge block contacts the slide bar 45, it squeezes the slide bar 45 to slide along the third slide groove 52 towards the fixed plate 51. During the sliding of the slide bar 45, the second spring 44 on the inner plate 42 is compressed to a compression amount of 2mm. The spring stores 0.4J of elastic potential energy. When the end of the slope of the wedge block 41 is disengaged from the slide bar 45, the second spring 44 releases the elastic potential energy instantly, pushing the slide bar 45 to reset along the third slide groove 52 at a speed of 1.2m / s. When the slide bar 45 resets, the striking head 46 at its end collides with the surface of the cutting blade 59, generating a high-frequency impact force of 240N, shaking off the cutting impurities attached to the blade surface. Meanwhile, the third spring 58 on the side wall of the cutting blade 59 contracts synchronously upon impact, buffering 20% ​​of the impact force and preventing rigid collision of the blade. The rubber damping pad between the turntable 38 and the rotating shaft 37 absorbs the reverse force transmitted to the turntable 38 when the slide bar 45 resets, with a vibration attenuation rate ≥80%, ensuring that the vibration amplitude of the drive motor 36 is ≤0.1mm, which meets the allowable vibration range of ≤0.2mm for conventional motors. This allows the equipment to automatically vibrate and shake off impurities generated by cutting on the cutting blade 59, achieving automated impurity cleaning of the gear cutting blade 59 without manual intervention. This avoids the impact of impurity accumulation on equipment operation, ensures continuous and efficient operation of the cutting device, reduces equipment downtime for cleaning, and improves overall production efficiency. In the fourth step, while the third step is being cleaned by tapping, the two lower sliders 45 slide back and forth along the third groove 52 in sync with the rotation of the turntable. When the slider 45 slides to the left end of the third groove 52, the first drain port 47 on the slider 45 completely overlaps with the second drain port 62 on the reservoir 61. Since the slider stroke of 8mm is less than or equal to the length of the first drain port of 10mm, the cutting fluid has sufficient flow time. The contact edge between the second drain port 62 and the first drain port 47 is fixed with a nitrile rubber sealing ring. When they overlap, the sealing ring is squeezed and deformed by the slider 45 by 0.5mm to form a sealing surface to prevent cutting fluid leakage. The air pressure valve on the top of the reservoir 61 is pre-adjusted to a working air pressure of 0.25MPa. With the gravitational potential energy that the liquid level in the reservoir 61 is higher than that of the second drain port, the air pressure pushes the cutting fluid to flow out quickly through the drain port, with a flow rate of 20mL / s. 2.5mL of cutting fluid can be discharged within the 0.125s overlap time. The cutting fluid flows parabolically through the first drain port 47 to the cutting blade 59, achieving rapid cooling of the cutting blade. At the same time, the cutting fluid causes impurities adhering to the blade surface to create tiny gaps due to thermal expansion and contraction, reducing the adhesion of impurities. This assists the third step of the tapping head 46 to achieve more thorough impurity removal, forming a synergistic effect of cleaning and cooling. This eliminates the need for the equipment to wait for the cutting blade 59 to cool down for a long time, significantly shortening the single processing cycle time. The equipment can be immediately put into the next cutting operation, greatly improving production efficiency and meeting the needs of large-volume continuous processing. Fifth, when the cutting fluid rapidly cools the cutting blade 59, the thermal expansion and contraction effect of the metal creates tiny gaps between the attached debris and the surface of the cutting blade 59. This increases the adhesion of the debris, making it easier for the debris to detach during subsequent hammering, thus improving the peeling efficiency.
