[0002] Pipe cutting machines have been widely used in the field of pipe cutting and processing, and have become one of the important equipment for various pipe manufacturing and processing enterprises. Such machines are suitable for cutting pipes of different materials such as metals, plastics, and composite materials, and can efficiently complete various tasks from rough machining to precision cutting. Due to its relatively simple operation, high cutting efficiency, and ability to adapt to various pipe specifications and shapes, pipe cutting machines are widely used in industries such as oil and gas, construction engineering, water treatment, power facilities, and machinery manufacturing, greatly improving the automation level and production efficiency of production lines.

These limitations in design make the equipment have many deficiencies when dealing with pipes of different sizes, shapes, and materials, and it is difficult to meet the requirements of various cutting tasks. Due to the lack of flexibility, traditional pipe cutting machines are prone to problems such as inaccurate positioning and blade deviation during the cutting process, resulting in uneven pipe cutting surfaces or non-compliance with predetermined specifications. These problems not only seriously affect the cutting accuracy and quality, but also may cause material waste and rework, reducing production efficiency.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

Detailed implementation manners

[0026] Now, the present utility model will be further described in detail with reference to the attached drawings.

[0027] Please refer to Figures 1-5As shown in the figure, in this embodiment, a pipe cutting machine is provided, which includes a frame 1. At both edges in the space above the frame 1, conveying rollers 2 are rotatably connected. A guiding mechanism 3 is arranged above the frame 1. In the space above the frame 1, a plate body 4 for the movement of the pipe is arranged between the two conveying rollers 2. In the space inside the frame 1, two groups of cutting components are rotatably connected. The cutting component includes two connecting plates 5 respectively fixedly connected to the middle part on one side of the frame 1. On one side of the connecting plate 5, a sliding plate component is slidably connected. Above the sliding plate component, a bearing seat 6 is fixedly connected. Between two opposite bearing seats 6, a rotating roller 7 is connected. A plurality of blades 8 are fixedly connected to the circumferential side of the rotating roller 7. And through grooves 9 adapted to the blades 8 are formed on the opposite sides of the plate body 4. On one side of one of the sliding plates, two servo motors 10 are fixedly connected. The servo motors 10 drive the rotating roller 7 through a synchronous structure. Through the setting of the sliding component, the user can conveniently and precisely adjust the position of the blade 8. This design is very flexible and can adapt to the cutting requirements of pipes of different sizes and types. When the blade 8 is not needed, the sliding component can safely retract the blade 8 into the interior of the frame 1, thus effectively avoiding the rust problem caused by the long-term exposure of the blade 8 to the external environment. In addition, such a design also greatly reduces the risk of accidental contact between the operator and the blade 8, further improving the safety of the equipment. At the same time, the equipment adopts a synchronous structure in the prior art, that is, through the close cooperation between the synchronous pulley and the synchronous belt, the coordinated operation of each component is realized. The synchronous structure in this application follows this mature technology, so the detailed principle is not described again.

[0028] In this embodiment, a positioning plate 11 is fixedly connected to the first edge on one side of the frame 1. On the side of the positioning plate 11 facing the inner wall of the frame 1, a driving motor 12 is fixedly connected. The output end of the driving motor 12 passes through the positioning rod and is connected with two gear A13. At the ends of the two conveying rods facing the gears, a gear B14 and a gear C15 are respectively fixedly connected. A first transmission belt 16 is sleeved between the gear A13 away from the positioning plate 11 and the gear B14, and a second transmission belt 17 is sleeved between the gear A13 close to the positioning plate 11 and the gear C15. The driving motor 12 is meshed with the gear B14 and the gear C15 through the connected gear A13, forming a set of precise transmission systems. This design enables the two conveying rollers 2 to be driven by the driving motor 12 to rotate simultaneously, thus realizing the function of synchronous operation. Through this synchronous transmission structure, the two conveying rollers 2 can maintain the same speed and direction, ensuring that the pipe body moves smoothly and uniformly during the conveying process. This not only prevents the possible offset or uneven speed of the pipe body during the conveying process, but also improves the working efficiency and cutting accuracy of the entire equipment.

[0029] In this embodiment, the guiding mechanism 3 includes four mounting brackets and a U-shaped bracket that slide on one side of the frame 1 respectively. A pressure roller 18 that can fit above the pipeline is connected between every two opposite mounting brackets. Electric push rods 19 are connected to both sides of the frame 1, and the telescopic ends of the electric push rods 19 are fixedly connected to the mounting brackets. A plurality of roller bodies 20 are fixedly connected in a straight line below the U-shaped bracket, and a space for the pipe body to move is left between every two adjacent roller bodies 20. By arranging the pressure roller 18 in the equipment, the movement stability of the pipe body during transportation and cutting is significantly improved. The pressure roller 18 can closely adhere to the surface of the pipeline and evenly distribute the applied pressure, so that the pipe body will not shake or deviate during movement, which is particularly important for subsequent precise cutting. In addition, the spacing of the roller bodies 20 is carefully adjusted to ensure that the pipe body can pass smoothly and is exactly matched with the position of the blade 8 during the cutting process. This spatial arrangement not only ensures that the relative position of the pipe body and the blade 8 remains unchanged during cutting, but also effectively prevents cutting errors or cutting failures caused by the deviation of the pipe body position, thereby improving the overall working efficiency and cutting quality.

[0030] In this embodiment, the slide plate assembly includes a plate body 4. A slider 21 is connected to one side of the plate body 4 by screws. A guide rail 22 for the slider 21 to slide is connected to one side of the connecting plate 5. The bearing seat 6 is installed above the slide plate. Sliders 21 are connected to both the side plate and one side of the plate body 4, and a guide rail 22 for the slider 21 to slide is provided on one side of the connecting plate 5. Such a design allows the slider 21 to freely slide on the guide rail 22, enabling the blade 8 to accurately adjust its position. Through the cooperation of the slider 21 and the guide rail 22, the operator can finely adjust the position of the blade 8, thereby achieving precise cutting.

[0031] In this embodiment, a guide groove is formed on one side of the connecting plate 5. A guide plate 23 located in the guide groove is connected to one side of the slide plate. A threaded hole is formed at the upper edge of the frame 1. A bearing cylinder 24 is fixedly connected above the threaded hole. A screw rod 25 is rotatably connected in the bearing cylinder 24. A threaded hole adapted to the screw rod 25 is formed on the opposite side of the guide plate 23. An operation-friendly knob is fixedly connected to the upper end of the screw rod 25. By manually rotating the knob, the rotation direction and speed of the screw rod 25 can be easily controlled. The design of the screw rod 25 not only takes into account the user's convenience of use, but also ensures the accuracy and stability of position adjustment. By adjusting the screw rod 25, the operator can accurately control the moving position of the blade 8 within the frame 1, enabling the blade 8 to be finely adjusted according to different cutting requirements.
