Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4As shown in the figure, a graphite steel plate cutting device includes a main board 1. Above the main board 1, a water spraying component is installed. The water spraying component includes a slider 2. On the top side of the slider 2, a water tank 3 is installed. On the top side of the water tank 3, a water inlet pipe 4 is connected. On one side of the water tank 3, a delivery pipe 5 is connected. On the outer wall of the delivery pipe 5, a pump 6 is installed. At one end of the delivery pipe 5, a nozzle 7 is installed. Inside the bottom end of the delivery pipe 5, a baffle 8 is rotatably connected through a rotating shaft. The radius of the baffle 8 is equal to the inner wall radius of the delivery pipe 5. One end of the rotating shaft is fixedly connected with a rotating handle 9. On the outer wall of the rotating handle 9, a pointing needle 10 is installed. Inside the rotating handle 9, a locking screw 11 is rotatably installed. During operation, in practical applications, a large amount of heat is generated during the cutting process of the graphite steel plate, and the cutting tool 19 will quickly heat up. The high temperature will cause the hardness and strength of the cutting tool 19 to decrease, resulting in easy wear, deformation, and even fracture, affecting the cutting accuracy and efficiency. Cooling water is injected into the water tank 3 through the water inlet pipe 4, and the pump 6 starts to work, causing the water in the water tank 3 to flow along the delivery pipe 5 and finally spray out from the nozzle 7 to cool the cutting tool 19. When adjusting the water flow rate, the operator rotates the rotating shaft through the rotating handle 9, thereby driving the baffle 8 to rotate inside the delivery pipe 5. The rotation of the baffle 8 will change the water passing cross-sectional area inside the delivery pipe 5. Through the cooperation of the pointing needle 10, when the baffle 8 is perpendicular to the axis of the delivery pipe 5, the water passing cross-sectional area is the smallest and the water flow is the smallest. When the baffle 8 is parallel to the axis of the delivery pipe 5, the water passing cross-sectional area is the largest and the water flow is the largest. Finally, the position of the rotating handle 9 and the baffle 8 is fixed by tightening the locking screw 11 to maintain a stable water flow rate, realizing the cooling of the cutting tool 19, preventing the cutting tool 19 from overheating, and thus improving the cutting quality.

[0024] Please refer to Figures 1-4As shown, an L-shaped plate 12 is installed at the top side edge of the main board 1. A chute 13 is opened inside the top end of the L-shaped plate 12. The slider 2 is slidably installed inside the chute 13. A stepping motor 14 is installed on one side of the L-shaped plate 12. The output end of the stepping motor 14 is installed with a threaded rod 15. A threaded hole is opened inside the slider 2. One end of the threaded rod 15 penetrates through the threaded hole and is rotatably installed on the inner wall of the chute 13. A cylinder 16 is installed on the bottom side of the slider 2. The acting end of the cylinder 16 is installed with a mounting frame 17. A cutting motor 18 is installed on one side of the mounting frame 17. The output end of the cutting motor 18 is installed with a cutting knife 19. The conveying pipe 5 is fixed inside the mounting block 20. During operation, in the manufacturing process of the vertical roller, it is necessary to cut the steel plate into the required size or shape to facilitate processing into the required vertical roller. Therefore, a cutting device is required. Start the stepping motor 14 to drive the threaded rod 15 to rotate. The slider 2 will slide horizontally along the chute 13. When the slider 2 slides, the mounting block 20 will drive the conveying pipe 5 to move accordingly, ensuring the cooling effect on the cutting knife 19. It can drive the cutting knife 19 to move above the steel plate. Then, start the cylinder 16, and its acting end pushes the mounting frame 17 to move downward, so that the cutting motor 18 and the cutting knife 19 move downward together. When the cutting knife 19 touches the graphite steel plate, the cutting motor 18 is started, and the cutting motor 18 drives the cutting knife 19 to rotate at a high speed to perform the cutting operation on the graphite steel plate, facilitating the adjustment of the horizontal position of the cutting knife 19 to meet the cutting requirements of different sizes and positions.

[0025] Please refer to Figure 1 、 2As shown in FIGS. 4 and 5, two mounting plates 21 are symmetrically mounted at one end of the top side of the main board 1. A servo motor 22 is mounted on one side of the mounting plate 21. A worm 23 is mounted on the output end of the servo motor 22. A rotating shaft 24 is rotatably mounted inside the top side of the main board 1. A worm gear 25 is mounted on the outer wall of the rotating shaft 24. A placing plate 26 is mounted on the top end of the rotating shaft 24. An annular groove 27 is formed in the main board 1 with the rotating shaft 24 as the center. Scale lines 28 are engraved on the top side of the main board 1 inside the annular groove 27. A sliding rod 29 is fixed at the bottom side edge of the placing plate 26. The bottom end of the sliding rod 29 is slidably mounted inside the annular groove 27. A sliding block 30 is slidably mounted inside the annular groove 27. Trigger blocks 31 are mounted on both sides of the sliding block 30. A fastening screw 32 is mounted inside the sliding block 30. Two support plates 33 are symmetrically mounted on the top side of the placing plate 26. An expansion rod 34 is penetratively mounted inside the top side of the support plate 33. A pressing plate 35 is fixedly connected to the acting end of the expansion rod 34. A control panel 36 is mounted on one side of the L-shaped plate 12; During operation, when manufacturing special-shaped mechanical parts, the steel plate needs to be adjusted to a specific angle for cutting to ensure that the parts can be accurately assembled. Place the steel plate on the placing plate 26. By operating the expansion rod 34, its acting end pushes the pressing plate 35, thereby fixing the steel plate on the placing plate 26 to ensure that the steel plate does not displace during cutting. When the angle of the steel plate needs to be adjusted, with the cooperation of the scale lines 28, move the sliding block 30 and the trigger block 31 to the required angle. Then fix the sliding block 30 through the fastening screw 32. Start the servo motor 22 to drive the worm 23 to rotate. The worm gear 25 will drive the rotating shaft 24 to rotate, so that the placing plate 26 rotates accordingly, and the sliding rod 29 will also slide inside the annular groove 27. When the sliding rod 29 slides into contact with the trigger block 31 on the sliding block 30, the trigger block 31 receives the pressure from the sliding rod 29 and transmits the signal to the control panel 36. The control panel 36 shuts down the servo motor 22 to achieve precise adjustment of the angle of the steel plate.

[0026] Working principle: Place the steel plate on the placing plate 26. By operating the expansion rod 34, its acting end pushes the pressing plate 35, thereby fixing the steel plate on the placing plate 26 to ensure that the steel plate does not displace during cutting;

[0027] Start the stepper motor 14 to drive the threaded rod 15 to rotate. The slider 2 will slide horizontally along the chute 13. When the slider 2 slides, the mounting block 20 will drive the conveying pipe 5 to move accordingly, ensuring the cooling effect on the cutting tool 19 and driving the cutting tool 19 to move above the steel plate. Then, start the cylinder 16, and its acting end pushes the mounting frame 17 downward, so that the cutting motor 18 and the cutting tool 19 move downward together. When the cutting tool 19 touches the graphite steel plate, the cutting motor 18 starts, and the cutting motor 18 drives the cutting tool 19 to rotate at a high speed to perform a cutting operation on the graphite steel plate, which is convenient for adjusting the horizontal position of the cutting tool 19 to meet the cutting requirements of different sizes and positions;

[0028] Inject cooling water into the water tank 3 through the water inlet pipe 4. The pump 6 starts to work, so that the water in the water tank 3 flows along the conveying pipe 5 and finally sprays out from the nozzle 7 to cool the cutting tool 19. When adjusting the water flow rate, the operator rotates the rotating shaft by turning the handle 9, thereby driving the baffle 8 to rotate inside the conveying pipe 5. The rotation of the baffle 8 will change the cross-sectional area of the water flow inside the conveying pipe 5 to achieve the cooling of the cutting tool 19 and prevent the cutting tool 19 from overheating, thereby improving the cutting quality;

[0029] When it is necessary to adjust the angle of the steel plate, cooperate with the scale line 28 to move the slider 30 and the trigger block 31 to the required angle. Subsequently, fix the slider 30 with the fastening screw 32. The servo motor 22 starts to drive the worm 23 to rotate, and the worm gear 25 will drive the rotating shaft 24 to rotate, so that the placing plate 26 rotates accordingly, and the sliding rod 29 will also slide in the annular groove 27. When the sliding rod 29 slides to contact the trigger block 31 on the slider 30, the trigger block 31 receives the pressure of the sliding rod 29 and transmits the signal to the control panel 36, and the control panel 36 turns off the servo motor 22 to achieve the precise adjustment of the angle of the steel plate.
