[0017] The limiting seat is fixedly connected to the bonding disc by the connecting bolts, and the bearing roller is rotatably connected to the bonding disc.

In conjunction with the guide frame, it guides the docking displacement block and the sliding block to slide within the limiting seat and the guide rod, thereby changing the position of the stabilizing frame, the motor, and the cutting disc.

[0018] Specifically, the control docking component includes a mounting side plate, on which a first stepper motor is mounted. A third gear is driven and connected to the first stepper motor. A tension shaft is telescopically connected to the side end of the third gear, and a fourth gear is fixedly connected to the side end of the tension shaft.

A second electrically controlled telescopic rod is mounted on the side end of the push support. The upper end of the push support is elastically telescopically connected to a spring rod. One side of the spring rod is fixed to a support base, and the other side of the spring rod is fixed to a fixed mounting frame. The lower end of the support base is fixedly connected to a carrier frame. The push support is slidably connected to the carrier frame. The second electrically controlled telescopic rod is fixed at the lower part of the fixed mounting frame.

[0019] Specifically, the derivation processing structure includes a fixed mounting plate, a guide slot seat fixedly mounted on the fixed mounting plate, a mounting slot plate fixedly connected to the side end of the fixed mounting plate, a control motor mounted on the mounting slot plate, a guide roller and a fifth gear disk driven and connected to the control motor, a support top frame fixedly connected to the side end of the mounting slot plate, a second stepper motor fixedly mounted at the lower end of the support top frame, a lead screw driven and connected to the second stepper motor, a mating threaded seat threadedly connected to the lead screw, a mating support fixedly connected to the mating threaded seat, the lead screw slidingly connected to a rod body set on the side of the support top frame, a ball rod provided on the mating support, the side end of the ball rod connected to a contact limiting roller, and the contact limiting roller telescopically connected to a spring telescopic seat.

[0020] Specifically, the steel pipe is guided and transported by guide rollers. The steel pipe is introduced through the center of the guide groove seat, passes through the guide rollers to reach the middle of the support top frame, and then passes through the mating support. The contact limit rollers extend and retract to squeeze and limit the steel pipe. The spring telescopic seat is hinged to the hinge shaft at the upper end of the second bearing support through the hinge shaft.

[0022] The beneficial effects of this invention are:

[0023] First, the present invention enables the traction of steel pipes through the setting of the guiding structure. The first electrically controlled telescopic rod changes the position of the guide frame by telescoping, so that the guide frame moves on the limiting rod and the base. A motor is fixedly installed on the guide frame by the mounting seat. An eccentric wheel is driven on the motor. By rotating the eccentric wheel, it can squeeze and limit the steel pipe, thereby performing the traction and stretching work of the steel pipe under the telescoping of the first electrically controlled telescopic rod.

[0024] Second, the present invention facilitates steel pipe cutting through its pipe-cutting structure, while also enabling efficient and continuous processing of the feed and rotation, facilitating equipment integration and mechanized production. When the first toothed ring rotates, the second toothed ring drives the second toothed disc to rotate, causing the first toothed disc to follow suit. The first toothed disc is fixed to the guide disc, causing the guide disc to rotate and the guide groove to move accordingly. The movement of the guide groove drives the movement of the guide frame, allowing the docking displacement block and the second toothed disc to slide and adjust on the limit seat and guide rod, changing the position of the stabilizing frame. A motor is installed on the stabilizing frame, controlling the rotation of the cutting disc for pipe cutting. Simultaneously, the third toothed ring drives the mating disc to rotate, causing the cutting part to rotate in a ring, achieving continuous pipe cutting. The first stepper motor provides power, driving the third and fourth toothed discs to rotate. The extension and retraction of the second electrically controlled telescopic rod changes the position of the push support, allowing the stretching shaft to stretch, thereby changing the position of the fourth toothed disc. This enables active control of the engagement between the fourth toothed disc and the first toothed ring, facilitating separate control under independent power sources.

[0025] Third, by deriving the structural design of the processing structure, it is convenient to guide and limit the movement of the steel pipe. The control motor drives the guide roller to rotate, so that the steel pipe moves on the guide roller. At the same time, the fifth toothed disc can drive the symmetrical fifth toothed disc at the lower end to rotate, thereby guiding the movement of the steel pipe. The second stepper motor can control the rotation of the lead screw to change the position of the mating threaded seat, so that the mating threaded seat drives the mating support to move. The ball rod can adjust the movement to pull the contact limit roller to move on the spring telescopic seat. At the same time, the spring telescopic seat is hinged to the hinge shaft on the second bearing support through the hinge shaft, which can change the tilt angle, so that the contact limit roller and the steel pipe are pressed into contact, and the limiting processing work is carried out during steel pipe cutting.

[0046] The invention will be further described below with reference to the accompanying drawings.

[0047] Example

[0048] like Figures 1-17 As shown, a pipe cutting machine with a rotating blade holder according to the present invention includes a steel pipe 1, a guide structure 2, a pipe cutting processing structure 3 and a pushing processing structure 4. The pipe cutting processing structure 3 is fixedly provided on the side end of the guide structure 2, and the pushing processing structure 4 is fixedly provided on the side end of the pipe cutting processing structure 3. The steel pipe 1 is provided through the center of the guide structure 2, the pipe cutting processing structure 3 and the pushing processing structure 4.

[0049] The first electrically controlled telescopic rod 5 pushes the guard plate 10, eccentric wheel 11, motor 12, and mounting base 13 to move via the guide frame 7. The motor 12 drives the eccentric wheel 11 to rotate, causing its protruding position to contact the steel pipe 1, thus limiting the movement of the steel pipe 1. Through the guide structure 2, the steel pipe 1 can be pulled. The first electrically controlled telescopic rod 5, by extending and retracting, changes the position of the guide frame 7, causing it to move on the limiting rod 8 and base 9. The motor 12 is fixedly mounted on the guide frame 7 via the mounting base 13. The motor 12 drives the eccentric wheel 11, which, through rotation, compresses and limits the movement of the steel pipe 1. Thus, under the extension and retraction of the first electrically controlled telescopic rod 5, the steel pipe 1 is pulled and stretched. The pipe cutting structure 3 is used for steel... For the cutting of pipe 1, the third toothed disc 42 controls the rotation of the third toothed ring 30, which in turn drives the cutting part 32 to rotate via the contact disc 31, thereby performing circumferential cutting of the steel pipe 1. When the fourth toothed disc 45 meshes with the first toothed ring 23, the second toothed ring 24 and the second toothed disc 25 drive the first toothed disc 22 to rotate, causing the guide disc 21 to rotate accordingly. The guide groove 20 guides the centering movement of the guide frame 38, causing the cutting disc 41 to move towards the center. The motor 40 drives the cutting disc 41 to rotate, performing the cutting process. The structural design of the pipe cutting processing structure 3 facilitates the pipe cutting work of steel pipe 1, and also facilitates efficient and continuous processing of the feed and rotation, making it easy to integrate the equipment and facilitating mechanized production. When the first toothed ring 23 rotates, the second toothed ring... 24 drives the second gear disc 25 to rotate, causing the first gear disc 22 to rotate accordingly. The first gear disc 22 is fixed to the guide disc 21, driving the guide disc 21 to rotate, causing the guide groove 20 to move accordingly. The movement of the guide groove 20 drives the movement of the cooperating guide frame 38, allowing the docking displacement block 37 and the second gear disc 25 to slide and adjust on the limiting seat 33 and the guide rod 36, changing the position of the stabilizing frame 39. The stabilizing frame 39 is equipped with a motor 40, which controls the rotation of the cutting disc 41 to perform pipe cutting. At the same time, the third gear ring 30 can drive the mating disc 31 to rotate, causing the cutting part 32 to rotate in a ring, realizing continuous pipe cutting. The first stepper motor 53 provides power, driving the third gear disc 42 and the fourth gear disc 45 to rotate, and The extension and retraction of the second electrically controlled telescopic rod 50 changes the position of the guide support 49, allowing the tension shaft 43 to extend, thereby changing the position of the fourth gear disc 45. This enables active control of the engagement between the fourth gear disc 45 and the first gear ring 23, facilitating separate control under independent power sources. The second stepper motor 66 drives the mating threaded seat 65 and the cooperating support 63 via the lead screw 64, causing the ball rod 62 to push the contact limiting roller 61 to move on the spring telescopic seat 60. The contact limiting roller 61 presses against the steel pipe 1, limiting its movement. The control motor 58 guides the steel pipe 1's displacement adjustment via the guide roller 57. The structural design of the guide processing structure 4 facilitates the guiding and limiting of the steel pipe 1. The control motor 58 drives the guide roller 57 to rotate.This causes the steel pipe 1 to move on the guide roller 57. Simultaneously, the fifth toothed disc 56 drives the symmetrically positioned lower fifth toothed disc 56 to rotate, thus guiding the steel pipe 1. The second stepper motor 66 controls the rotation of the lead screw 64, changing the position of the mating threaded seat 65. This causes the mating threaded seat 65 to drive the mating support 63 to move. The ball rod 62 adjusts its movement, pulling the contact limiting roller 61 onto the spring telescopic seat 60. The spring telescopic seat 60 is hinged to the hinge shaft 68 on the second bearing support 19 via the hinge shaft 68, allowing for changes in its tilt angle. This ensures that the contact limiting roller 61 makes contact with the steel pipe 1, performing the limiting process during steel pipe 1 cutting.

[0050] The guide structure 2 includes a base 9, a partition 6 is fixedly provided on the side of the base 9, a first electrically controlled telescopic rod 5 is installed on the partition 6, the first electrically controlled telescopic rod 5 controls the lateral movement of the guide frame 7, the lower end of the guide frame 7 slides with the limiting rod 8, and the limiting rod 8 is fixedly connected to the partition 6, the upper end of the guide frame 7 is fixedly connected to the mounting base 13, a motor 12 is installed on the mounting base 13, the motor 12 controls the rotation of the eccentric wheel 11, and a guard plate 10 is fixedly provided on the upper side of the mounting base 13;

[0051] Motor 12 controls the eccentric wheel 11 to rotate between the guard plate 10 and the mounting base 13. The eccentric wheel 11 is pressed and limited by the protruding position against the steel pipe 1. The first electrically controlled telescopic rod 5 controls the guide frame 7 to move on the limiting rod 8 and the base 9 by telescopic movement, pulling the steel pipe 1 to pass through the guide structure 2, the pipe cutting structure 3, and the pushing processing structure 4 for continuous guiding processing. First, the guide structure 2 is controlled to work to position the front end of the steel pipe 1, thereby ensuring the stability of the steel pipe 1. At the same time, the guide structure 2 can drive the steel pipe 1 to move, thereby lifting a fixed length to achieve the purpose of fixed-length guidance. First, motor 12 controls the eccentric wheel 11 to rotate, so that the protruding position of the eccentric wheel 11 contacts and presses against the steel pipe 1 to limit the steel pipe 1, so that the steel pipe 1 is limited on the guide frame 7. At this time, the first electrically controlled telescopic rod 5 controls the extension adjustment, so that the guide frame 7 moves on the limiting rod 8 and the base 9, driving the steel pipe 1 to move together, so that the steel pipe 1 is stretched, thereby performing fixed-length guidance of the steel pipe 1.

[0052] The pipe cutting processing structure 3 includes a cutting guide component 14 and a control docking component 15.

The adjusting mechanism 16 docks and guides the driven cutting mechanism 18. A mating hinge seat 69 is fixedly mounted on the second bearing support 19. The work begins with the cutting of steel pipe 1. At this time, the first stepper motor 53 starts, driving the third gear disc 42, the stretching shaft 43, and the fourth gear disc 45 to rotate. The third gear disc 42 controls the rotation of the third gear ring 30, causing it to rotate on the inner alignment disc 27 and the mating disc 28 via bearing rollers 29. The rotation of the third gear ring 30 drives the mating disc 31 to move accordingly. The cutting part 32, fixedly mounted on the mating disc 31, rotates and adjusts accordingly. Simultaneously, the fourth gear disc 45 engages with the first gear ring 23, carrying... The first gear ring 23 rotates, which in turn drives the second gear ring 24 to rotate. The second gear ring 24 drives the first gear disc 22 to rotate via the second gear disc 25. The first gear disc 22 drives the guide disc 21 to rotate. At this time, the guide groove 20 moves in coordination with the guide disc 21. The guide groove 20 is adapted to the mating guide frame 38, thereby pushing the docking displacement block 37 and the sliding block 35 to move. At this time, the sliding block 35 slides and adjusts on the limit seat 33 and the guide rod 36. The docking displacement block 37 changes the position of the motor 40 and the cutting disc through the stabilizing frame 39. At position 41, motor 40 can also control the rotation of cutting disc 41, thereby performing the cutting process of steel pipe 1 through cutting disc 41. When sliding block 35 reaches the lowest position, the distance sensor in limit seat 33 senses the position of sliding block 35 and controls the second electric telescopic rod 50 to work, so that the second electric telescopic rod 50 pushes the push support 49 to move. The push support 49 drives the tension shaft 43 to stretch through push block 44, so that the fourth toothed disc 45 disengages from the first toothed ring 23. At this time, sliding block 35 is reset under the action of spring.

[0053] The adjustment mechanism 16 includes a guide plate 21, on which three guide grooves 20 are provided. The guide grooves 20 are arc-shaped.

The two fifth toothed discs 56 are meshed and connected, so that the two guide rollers 57 rotate in opposite directions, driving the steel pipe 1 to be guided. After reaching the specified length, the second stepper motor 66 works at this time, driving the lead screw 64 to rotate. The lead screw 64 is threadedly connected to a mating threaded seat 65, which allows the mating threaded seat 65 and the mating support 63 to slide and limit the position of the ball rod 62 on the side of the support top frame 59, changing the position of the ball rod 62. Both ends of the ball rod 62 are set with a spherical structure, and the spring telescopic seat 60 and the contact limiting roller 61 are set at an inclination, which can cooperate with the ball rod 62. At the same time, the spring telescopic seat 60 is hinged to the hinge shaft 68 through the mating hinge seat 69, which allows the spring telescopic seat 60 to change angle. Thus, when the ball rod 62 moves, it drives the contact limiting roller 61 to change angle and length, so that the contact limiting roller 61 is pressed into contact with the steel pipe 1, and performs the limiting work of the steel pipe 1.

[0061] The steel pipe 1 is guided and transported by the guide roller 57. The steel pipe 1 is introduced through the center of the guide groove seat 54, passes through the guide roller 57 to reach the middle of the support top frame 59, and then passes through the mating support 63. The contact limit roller 61 is extended and retracted to squeeze and limit the steel pipe 1. The spring telescopic seat 60 is hinged to the hinge shaft 68 at the upper end of the second bearing support 19 through the hinge shaft 68. The steel pipe 1 passes through and is aligned with the center of the inner plate 27, the mating plate 28, the guide plate 21, and the second toothed ring 24, and then connects to the upper end of the guide frame 7.

[0062] The rear end of the fixed mounting bracket 51 is fixedly connected to the bottom of the second bearing support 19. The third gear plate 42, through meshing with the third gear ring 30, drives the mating plate 31 and the cutting part 32 to rotate. The inner plate 27 and the mating plate 28 are aligned and supported by the bearing roller 29 for the third gear ring 30. The push support 49 is displaced, which drives the push block 44 to move, causing the tension shaft 43 to be stretched, controlling the position of the fourth gear plate 45, so that the fourth gear plate 45 is aligned and meshed with the first gear ring 23.

[0063] Working principle: The steel pipe 1 is passed through the guide structure 2, the pipe cutting structure 3, and the pushing structure 4 for continuous guiding processing. First, the guide structure 2 is controlled to operate and position the front end of the steel pipe 1 to ensure its stability. At the same time, the guide structure 2 can drive the steel pipe 1 to move, thereby lifting it to a fixed length to achieve the purpose of fixed-length guiding. First, the motor 12 controls the eccentric wheel 11 to rotate, so that the protruding part of the eccentric wheel 11 contacts and squeezes the steel pipe 1 to limit the steel pipe 1, so that the steel pipe 1 is limited on the guide frame 7. At this time, the first electric telescopic rod 5 controls the tension adjustment, so that the guide frame 7 moves on the limit rod 8 and the base 9, driving the steel pipe 1 to move together, so that the steel pipe 1 is stretched, thereby performing the fixed-length guiding work of the steel pipe 1.

[0064] After being pulled to the designated length, the push-processing structure 4 also begins to work. The control motor 58 controls the rotation of the guide roller 57. A fifth toothed disc 56 is located at the rear end of the guide roller 57, which drives the fifth toothed disc 56 to rotate. The two fifth toothed discs 56 mesh with each other, causing the two guide rollers 57 to rotate in opposite directions, guiding the steel pipe 1 to the designated length. At this point, the second stepper motor 66 starts working, driving the lead screw 64 to rotate. The lead screw 64 is threaded with a mating threaded seat 65, enabling the mating threaded seat 65 to engage with the support. 63 slides at the side end of the support top frame 59 to change the position of the ball rod 62. Both ends of the ball rod 62 are set with a spherical structure, and the spring telescopic seat 60 and the contact limiting roller 61 are set at an angle to cooperate with the ball rod 62. At the same time, the spring telescopic seat 60 is hinged to the hinge shaft 68 through the cooperation hinge seat 69, which allows the spring telescopic seat 60 to change its angle. Thus, when the ball rod 62 moves, it drives the contact limiting roller 61 to change its angle and length, so that the contact limiting roller 61 is pressed into contact with the steel pipe 1 to perform the limiting work of the steel pipe 1.

[0065] Then, the pipe cutting processing structure 3 begins operation, performing the cutting process on the steel pipe 1. At this time, the first stepper motor 53 starts, driving the third gear disc 42, the stretching shaft 43, and the fourth gear disc 45 to rotate. The third gear disc 42 controls the rotation of the third gear ring 30, causing the third gear ring 30 to rotate on the inner alignment disc 27 and the mating disc 28 via the bearing rollers 29. The rotation of the third gear ring 30 drives the mating disc 31 to move accordingly. The cutting part 32 is fixedly installed on the mating disc 31, causing the cutting part 32 to rotate and adjust accordingly. At this time, the fourth gear disc 45 also engages with the first gear ring 23, driving the first gear ring 23 to rotate. When the first gear ring 23 rotates, it drives the second gear ring 24 to rotate in coordination. The second gear ring 24 drives the first gear disc 22 to rotate via the second gear disc 25. The first gear disc 22 drives the guide disc 21 to rotate, and the guide groove 20 follows the guide disc 21. In coordination with the movement, the guide groove 20 is adapted to the guide frame 38, thereby pushing the docking displacement block 37 and the sliding block 35 to move. At this time, the sliding block 35 slides and adjusts on the limit seat 33 and the guide rod 36. The docking displacement block 37 changes the position of the motor 40 and the cutting disc 41 through the stabilizing frame 39. The motor 40 can also control the rotation of the cutting disc 41, thereby performing the cutting process of the steel pipe 1 through the cutting disc 41. When the sliding block 35 reaches the lowest position, the distance sensor in the limit seat 33 senses the position of the sliding block 35 and controls the second electric telescopic rod 50 to work, so that the second electric telescopic rod 50 pushes the push support 49 to move. The push support 49 drives the tension shaft 43 to stretch through the push block 44, so that the fourth toothed disc 45 disengages from the first toothed ring 23. At this time, the sliding block 35 resets under the action of the spring, completing the cutting process.
