Description

Technical Field

[0001] This application relates to the field of high-speed metal circular saw technology, and in particular to a chip removal device for a high-speed metal circular saw for cutting metal materials. Background Technology

[0002] A high-speed metal circular saw is a metal processing device that uses a high-speed rotating circular saw blade to cut pipes, bars, and other profiles through a feed mechanism. Existing high-speed metal circular saws include a cutting assembly and a conveying assembly. The conveying assembly transports the workpiece to the cutting station. The rotation of the cutting assembly, combined with cooling nozzles spraying cutting oil onto the circular saw blade, and the workpiece is cut by the quantitative feed of the circular saw blade.

[0003] However, when traditional high-speed metal circular saws process metal pipes, the high-speed flying debris generated by the circular saw blade spreads in multiple directions. Some of the debris falls into the pipe inside on both sides of the saw blade. When the cutting oil on the circular saw blade comes into contact with metal debris and powder, it forms a very thin liquid film on the metal surface, causing the cutting debris to adhere to the inner wall of the pipe. This can easily affect the processing quality of subsequent processes such as welding and assembly. Furthermore, the debris inside the pipe near the conveying mechanism may come into contact with the circular saw blade again, causing additional wear on the circular saw blade and affecting its service life. Summary of the Invention

[0004] This application proposes a chip removal device for a high-speed metal circular saw for cutting metal materials. It has the advantages of removing chips from metal pipes and improving the cleaning effect, thereby solving the problems of chips adhering to the inner wall of pipes affecting the quality of subsequent processes and the additional wear caused by the circular saw blade coming into extra contact with chips.

[0005] To achieve the above objectives, this application adopts the following technical solution: a chip removal device for a high-speed metal circular saw for cutting metal materials, comprising a support and a cutting mechanism, an air jet mechanism being provided on one side of the support, a drive mechanism being fixedly provided on one side of the support, a movable seat being slidably provided on one side of the top of the support, an adjusting seat being provided on one side of the movable seat, a discharge pipe being fixedly sleeved on the adjusting seat, a support roller being provided on one side of the top of the support, a scraper being provided on one side of the adjusting seat, and also comprising an adjusting mechanism;

[0006] The adjustment mechanism can drive the moving seat to move horizontally, synchronously change the horizontal position of the scraper according to the moving position of the workpiece, and drive the support roller to rotate so that when the scraper extends into the workpiece, the workpiece rotates relative to the scraper.

[0007] Furthermore, a second push rod is fixedly installed on one side of the top of the bracket. The output end of the second push rod is connected to the moving seat via a transmission. A rotating seat is installed on one side of the moving seat. A push rod is fixedly connected to one side of the rotating seat. The rotating seat is slidably sleeved with the discharge pipe.

[0008] Furthermore, the distance between the support roller and the cutting mechanism is less than the length of the workpiece along its axial direction, a spring is provided between the adjusting seat and the rotating seat, and a rotating ring is rotatably provided on one side of the adjusting seat.

[0009] Furthermore, a rack is slidably mounted on the top of the bracket, a connecting shaft is rotatably mounted on the top of the bracket, and a transmission shaft is rotatably mounted on the top of the bracket. The transmission shaft is used to drive the support roller to rotate. A bevel gear is fixedly sleeved on one side of both the transmission shaft and the connecting shaft. A transmission gear is fixedly sleeved on one end of the connecting shaft. A hollow shaft is fixedly mounted on one side of the movable seat. A transmission rod is fixedly connected to one end of the rack, and a fixed shaft is fixedly connected to the top of the transmission rod.

[0010] Furthermore, the two bevel gears mesh with each other, the transmission gear meshes with the rack, the fixed shaft is rotatably sleeved inside the hollow shaft and the fixed shaft is collinear with the hollow shaft, and the axis of the support roller is parallel to the axis of the workpiece.

[0011] Furthermore, an adjusting cylinder is fixedly connected to one side of the adjusting seat, and a second sliding rod is slidably sleeved on the inner side of the adjusting cylinder. The second sliding rod is T-shaped, and a spring is fixedly connected to the bottom of the second sliding rod. The length of the scraper is greater than the axial length of the workpiece, and one end of the scraper is inclined.

[0012] Furthermore, a support plate is fixedly connected to the top of the movable seat, and a fixed cylinder is fixedly connected to one side of the support plate. A sliding rod is slidably sleeved inside the fixed cylinder. The sliding rod is T-shaped, and a connecting rod is fixedly connected to the bottom of the sliding rod. A pressure plate is fixedly connected to one end of the connecting rod, and a moving shaft is fixedly connected to one end of the connecting rod. A push rod is fixedly installed on one side of the top of the support plate, and an adjusting plate is fixedly connected to the output end of the push rod. An adjusting groove is opened on one side of the adjusting plate. The adjusting groove is set as an inclined groove, and the moving shaft is slidably sleeved with the adjusting groove.

[0013] Furthermore, the drive shaft is set as a keyed shaft, and the drive shaft is connected to the support roller through the key. While the drive shaft drives the support roller to rotate, the support roller can slide axially. A top rod is fixedly connected to one side of the bottom of the adjusting seat, and the length of the teeth of the rack is adapted to the length of the drive shaft.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The chip removal device of a high-speed metal circular saw for cutting metal materials provided in this application uses an air jet mechanism to move synchronously with the conveying mechanism when the pipe is fed and to spray air into the pipe. Before each round of cutting action begins, the airflow discharges the chips splashed on both sides of the circular saw blade through the discharge pipe, so that the chips are less likely to remain in the pipe to be processed, reducing the possibility of chips coming into contact with the circular saw blade again, thereby extending the service life of the circular saw blade and ensuring the cleanliness of the workpiece, avoiding the contamination of the workpiece by chips and affecting the quality of subsequent processes.

[0016] 2. The chip removal device for a high-speed metal circular saw for cutting metal materials provided in this application moves the movable seat through the second push rod, and drives the scraper to move axially synchronously while simultaneously extending into the tubes on both sides of the circular saw blade. At the same time, the adjustment mechanism drives the support roller to rotate, causing the support roller to rotate the tubes, so that the chips adhering to the tubes are carried to the top and hung down by the scraper. With the airflow blown by the jet mechanism, the chips are carried out during the fall, thereby reducing the possibility that chips will adhere to the inner wall of the tubes after contacting the cutting oil without being carried out by the airflow, thus improving the chip removal efficiency and further improving the cleaning effect.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1, as Figures 1-6 A chip removal device for a high-speed metal circular saw for cutting metal materials includes a support 1 and a cutting mechanism 2. The workpiece is conveyed to the cutting station of the cutting mechanism 2 by the conveying mechanism of the high-speed metal circular saw. The cutting mechanism 2 cuts the tubular workpiece. A drive mechanism 4 is fixedly installed on one side of the support 1, and an air jet mechanism 3 is installed on the other side of the support 1. The air jet mechanism 3 is located on the side of the conveying mechanism, that is, on the side of the cutting mechanism 2 near the feed. The air jet mechanism 3 can be configured as a blower. The air jet mechanism 3 is used to spray air from the end of the workpiece 5 away from the cutting mechanism 2 into the tube cavity. The drive mechanism 4 is connected to the air jet mechanism 3 for transmission. The drive mechanism 4 is used to drive the air jet mechanism 3 to move horizontally. As the workpiece 5 is fed by the conveying mechanism, the length of the workpiece 5 decreases. The drive mechanism 4 drives the air jet mechanism 3 to always fit against the end of the workpiece 5 and move horizontally synchronously with the workpiece 5 fed by the conveying mechanism.

[0027] The drive mechanism 4 can be configured as a linear conveyor belt module. For example, the jetting mechanism 3 is mounted on the slider of the horizontal slide table. Both sides of the slide are equipped with drive wheels, which are connected via a drive belt. The drive belt is fixedly connected to the slider. A drive motor drives the drive wheels to rotate, which in turn drives the drive belt, causing the slider to move horizontally along the slide table. A movable seat 6 is slidably mounted on one side of the top of the bracket 1. A second push rod 30 is fixedly mounted on one side of the top of the bracket 1. The output end of the second push rod 30 is connected to the movable seat 6. The second push rod 30 is used to drive the movable seat 6 to move horizontally. (See reference...) Figure 4 A discharge pipe 9 is provided at the middle position of the movable seat 6, and an adjusting seat 8 is provided on one side of the movable seat 6. The adjusting seat 8 is fixedly connected to the discharge pipe 9. A cavity is opened on one side of the adjusting seat 8, and the cavity is connected to the cavity of the discharge pipe 9. The discharge pipe 9 is L-shaped.

[0028] A waste bin is provided on one side of the bottom of the support 1. One end of the discharge pipe 9 extends into the inside of the waste bin. Preferably, the cavity is a conical cavity with a maximum radius smaller than the outer diameter of the pipe fitting, to ensure that airflow passes through the discharge pipe 9 as much as possible. (See reference...) Figure 4A support roller 11 is provided on one side of the top of the bracket 1. The support roller 11 is used to support the finished workpiece 5. A discharge box for storing the finished products is provided on one side of the waste box. The distance between the support roller 11 and the cutting mechanism 2 is less than the axial length of the workpiece 5, so that the pipe can be pushed away from the contact with the support roller 11 and fall after being pushed a distance of its own axial length.

[0029] In use, the second push rod 30 drives the moving seat 6 to move horizontally, and the moving seat 6 drives the adjusting seat 8 to move, so that one end face of the adjusting seat 8 is in contact with the end face of the pipe in a fixed state at the cutting station. At this time, the pipe cavity is connected to the cavity of the adjusting seat 8. After the pipe is cut, the conveying mechanism feeds the material. The pipe to be cut pushes the cut pipe to move horizontally on the top of the support roller 11. The second push rod 30 retracts synchronously, and the drive mechanism 4 drives the air jet mechanism 3 to contact the end face of the pipe to be processed. The air jet mechanism 3 starts and blows out air. At this time, the connecting surfaces of the two pipes are in contact. The air jet carries the debris in the two pipes through the cavity into the discharge pipe 9. The debris is discharged from the outlet of the discharge pipe 9 into the waste bin until the processed pipe moves its own length and the pipe is separated from the contact with the support roller 11. The second push rod 30 continues to retract, the air jet mechanism 3 stops blowing air, and the pipe falls into the storage bin, completing one round of processing and chip removal.

[0030] A rotating seat 7 is provided on one side of the movable seat 6, see reference. Figure 6 A first push rod 20 is fixedly connected to one side of the rotating seat 7, and a second push rod 30 is hinged to one side of the top of the movable seat 6. Both the first push rod 20 and the second push rod 30 are electric push rods. The output end of the first push rod 20 is connected to the rotating seat 7 in a hinged manner. The rotating seat 7 is slidably sleeved with the discharge pipe 9. Preferably, the discharge pipe 9 is slidably sleeved with the rotating seat 7 through a flat key. A spring is provided between the adjusting seat 8 and the rotating seat 7, and the corresponding spring is movably sleeved on the outside of the discharge pipe 9.

[0031] When the second push rod 30 pushes the movable seat 6 close to the fixed pipe fitting, the movable seat 6 drives the rotating seat 7 to move. The rotating seat 7 drives the adjusting seat 8 to move through the elastic force of the corresponding spring, so that the adjusting seat 8 fits the end face of the pipe fitting under the action of the spring force, ensuring that the end face of the pipe fitting fits the end face of the adjusting seat 8 during subsequent movement.

[0032] A scraper 10 is provided on one side of the adjusting seat 8. The distance from the scraper 10 to the center line of the cavity of the adjusting seat 8 is adapted to the inner diameter of the pipe. A rack 16 is slidably provided on the top of the support 1. A connecting shaft 13 is rotatably provided on the top of the support 1. A transmission shaft 12 is rotatably provided on the top of the support 1. The transmission shaft 12 is used to drive the support roller 11 to rotate. (See reference) Figure 6A bevel gear 14 is fixedly sleeved on one side of both the drive shaft 12 and the connecting shaft 13. The two bevel gears 14 mesh with each other. A drive gear 15 is fixedly sleeved on one end of the connecting shaft 13. The drive gear 15 meshes with the rack 16. A hollow shaft 18 is fixedly installed on one side of the moving seat 6. A drive rod 17 is fixedly connected to one end of the rack 16. A fixed shaft 19 is fixedly connected to the top of the drive rod 17. The fixed shaft 19 is rotatably sleeved on the inner side of the hollow shaft 18 and the fixed shaft 19 is collinear with the hollow shaft 18. The axis of the support roller 11 is parallel to the axis of the pipe. The support roller 11 is also used to drive the workpiece to rotate circumferentially. A rotating ring 32 is rotatably installed on one side of the adjusting seat 8. The outer diameter of the rotating ring 32 is adapted to the outer diameter of the pipe. A retaining ring is fixedly installed on the body of the discharge pipe 9. The retaining ring is located on one side of the rotating seat 7 and is used to limit the range of movement of the adjusting seat 8 relative to the rotating seat 8.

[0033] During the retraction of the second push rod 30, the moving seat 6 moves, driving the rotating seat 7 to move. The rotating seat 7 drives the hollow shaft 18 to move, which in turn drives the fixed shaft 19 to move. The fixed shaft 19 drives the transmission gear 15 to rotate via the transmission rod 17 and rack 16. The transmission gear 15 drives the connecting shaft 13 to rotate, which in turn drives the transmission shaft 12 to rotate via the two bevel gears 14. The transmission shaft 12 drives the support roller 11 to rotate, which in turn drives the workpiece to rotate. The workpiece drives the rotating ring 32 to rotate relative to the adjusting seat 8. The scraper 10 is fixed in position relative to the adjusting seat 8 and located at the top of the pipe, thus removing debris that adheres to the inner wall of the pipe and is not easily carried by the airflow. The airflow generated by the combined jet mechanism 3 carries the falling debris out of the discharge pipe 9, thereby improving the cleaning effect and efficiency of the debris, reducing the possibility that debris with cutting oil adheres to the inner wall of the pipe and is not easily carried away by the airflow, reducing the possibility that residual debris will come into contact with the circular saw blade again, and extending the service life of the circular saw blade. After the conveying device feeds the material into place, the second push rod 30 continues to retract while the first push rod 20 extends, driving the rotating seat 7 to rotate to an inclined position. The workpiece 5 slides down along the scraper 10. At this time, the fixed shaft 19 rotates relative to the hollow shaft 18. During the process of cleaning debris, the workpiece 3 is fed in a synchronous manner, ensuring the cleaning effect without affecting the processing efficiency of the workpiece 3.

[0034] Example 2, as Figures 3-6 Based on Embodiment 1, an adjusting cylinder 28 is fixedly connected to one side of the adjusting seat 8, and a second sliding rod 29 is slidably sleeved on the inner side of the adjusting cylinder 28. Preferably, the second sliding rod 29 is slidably connected to the adjusting cylinder 28 via a flat key. The second sliding rod 29 is fixedly connected to the scraper rod 10. The second sliding rod 29 is T-shaped and can slide axially relative to the adjusting cylinder 28 without disengaging from it. A spring is fixedly connected to the bottom of the second sliding rod 29. The length of the scraper rod 10 is greater than the axial length of the workpiece 5, and one end of the scraper rod 10 is inclined.

[0035] During the process of the second push rod 30 driving the adjusting seat 8 to approach the workpiece 5, the adjusting seat 8 drives the adjusting cylinder 28 to move, and the adjusting cylinder 28 drives the second sliding rod 29 to move, thereby driving the scraper 10 to approach the workpiece 5. One end of the tube of the workpiece 5 contacts the inclined rod of the scraper 10, pushing the scraper 10 to overcome the elastic force of the corresponding spring and contract until the second push rod 30 drives the scraper 10 to partially extend into the workpiece 5. After the workpiece 5 is processed, the second push rod 30 continues to extend, driving the scraper 10 to fully extend into the workpiece 5. Under the push of the corresponding spring force, the scraper 10 adheres to the inner wall of the tube. This ensures that the scraper can scrape off small debris while adapting to tubes with different inner diameters or wall thicknesses, improving the flexibility of the chip removal device.

[0036] Example 3, as Figures 3-6 Based on Embodiment 2, a support plate 21 is fixedly connected to the top of the movable seat 6, and a fixed cylinder 22 is fixedly connected to one side of the support plate 21. A first sliding rod 23 is slidably sleeved on the inner side of the fixed cylinder 22. The first sliding rod 23 is slidably connected to the fixed cylinder 22 by a flat key. The first sliding rod 23 is T-shaped and can slide axially relative to the fixed cylinder 22 without detaching from it. A connecting rod 24 is fixedly connected to the bottom of the first sliding rod 23, and a pressure plate 31 is fixedly connected to one end of the connecting rod 24. A movable shaft 25 is fixedly connected to one end of the rod body. A third push rod 34 is fixedly installed on one side of the top of the support plate 21. An adjusting plate 26 is fixedly connected to the output end of the third push rod 34. The third push rod 34 is used to drive the adjusting plate 26 to move horizontally. An adjusting groove 27 is opened on one side of the adjusting plate 26. The adjusting groove 27 is set as an inclined groove. The movable shaft 25 is embedded in the adjusting groove 27. The movable shaft 25 is slidably sleeved with the adjusting groove 27 in a rolling contact manner through a bearing. The adjusting groove 27 is used to adjust the height of the movable shaft 25. A pressure roller is provided at the bottom of the pressure plate 31.

[0037] As the rotating ring 32 approaches the workpiece 5, it is driven by the workpiece 5 to move closer to the rotating seat 7. The rotating ring 32 drives the adjusting seat 8 to move horizontally relative to the rotating seat 7. The third push rod 34 retracts, causing the adjusting plate 26 to move, changing the corresponding position of the adjusting groove 27 and the moving shaft 25. The inner wall of the adjusting groove 27 abuts against the bearing of the moving shaft 25, pushing the moving shaft 25 to descend. The moving shaft 25 drives the connecting rod 24 to descend, and the connecting rod 24 drives the pressure plate 31 to descend. At the same time, the rotating seat 7, in conjunction with the fixed cylinder 22, the first sliding rod 23, and the connecting rod 24, drives the pressure plate 31 to move synchronously with the workpiece 5. This allows the pressure plate 31 to apply pressure close to the support roller 11 to the pipe while avoiding relative displacement between the pressure plate 31 and the workpiece 5, which would cause additional wear. This ensures the service life of the chip removal device while ensuring the support roller 11's pressure on the pipe.

[0038] Example 4, as Figures 3-6The drive shaft 12 is set as a key shaft. The drive shaft 12 is connected to the support roller 11 through the key. While the drive shaft 12 drives the support roller 11 to rotate, the support roller 11 can slide axially. A top rod 33 is fixedly connected to one side of the bottom of the adjusting seat 8. The length of the teeth of the rack 16 is adapted to the length of the drive shaft 12.

[0039] During the rotation of the workpiece 5 driven by the support roller 11, the workpiece drives the support roller 11 to move axially through friction until the support roller 11 moves to contact the bracket. At this time, the support roller 11 drives the workpiece to complete at least one rotation. The rack 16 disengages from the transmission gear 15, and the workpiece 5 moves axially relative to the support roller 11. This avoids additional wear caused by the support roller 11 rotating relative to the workpiece 5 while moving axially under the pressure of the pressure plate 31, thereby further improving the service life of the chip removal device.
