Technical Field

[0001] This utility model relates to the field of steel pipe cutting and kerf smoothing technology, and in particular to a tool for smoothing steel pipe cutting and kerf smoothing. Background Technology

[0002] In today's booming industrial sector, various pipeline engineering projects are underway at a rapid pace, from large-scale oil pipelines to the intricate urban water and gas supply networks. Steel pipes, as a fundamental and crucial structural material, have a wide range of applications and are used in massive quantities. With continuously improving engineering quality standards, the requirements for precision in steel pipe processing are becoming increasingly stringent. The quality of the cut surface after steel pipe cutting directly affects subsequent installation, connection, and the operational stability and safety of the entire system. This makes the search for tools to smoothly process steel pipe cut surfaces an urgent need in the industry.

[0003] Most steel pipe cutting processes are based on mechanical cutting principles, such as common methods like abrasive wheel cutting and saw blade cutting. Taking abrasive wheel cutting as an example, the high-speed rotating abrasive wheel achieves the cutting purpose by contacting and grinding the surface of the steel pipe.

[0004] In existing technologies, some devices often rely on the weight of the newly replaced steel pipes and the uneven friction between them, which can cause the steel pipes to easily shift during the cutting process, resulting in skewed and stuck cuts. To address this issue, a tool for smoothing the cut of steel pipes is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tool for smoothing the cut of steel pipes, which aims to improve the problem of fixing steel pipes in some existing devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel pipe cutting and kerf smoothing tool, comprising a supporting base plate, a sliding groove fixedly connected to the top of the supporting base plate, a fixing mechanism provided outside the sliding groove, a pushing mechanism provided at the top of the supporting base plate, and a cutting assembly for trimming fixedly connected to the top of the supporting base plate. The fixing mechanism includes a cylinder, the cylinder being fixedly connected to the inside of the sliding groove, a pushing bar fixedly connected to the driving end of the cylinder, a fixing block slidably connected to the outside of the pushing bar, two rolling shafts slidably connected to the outer sides of the fixing block, and a clamping assembly for positioning rotatably connected to the outside of the rolling shafts.

[0007] As a further description of the above technical solution: the pushing mechanism includes a fixing bar and a fixing clamp, the bottom of the fixing bar is fixedly connected to the top of the supporting base plate, and a pushing roller is rotatably connected inside the fixing bar;

[0008] As a further description of the above technical solution: the clamping assembly includes a rotating link, two rotating links are rotatably connected to the outer sides of the rolling shaft, a rotating fixed shaft is rotatably connected to the middle of the two rotating links, and a support frame is fixedly connected to the outside of the rotating fixed shaft;

[0009] As a further description of the above technical solution: a push column is fixedly connected to the top of the fixed block, and a spring is sleeved between the two rolling shafts on the outside of the fixed block;

[0010] As a further description of the above technical solution: the bottom of the fixing clamp is fixedly connected to the top of the supporting base plate, and a rotating shaft is fixedly connected inside the fixing clamp;

[0011] As a further description of the above technical solution: the cutting assembly includes a fixed plate, a rotating plate is rotatably connected inside the fixed plate, and a motor is fixedly connected outside the rotating plate;

[0012] As a further description of the above technical solution: a repair knife is fixedly connected to the drive end of the motor, and a protective baffle is fixedly connected to the outside of the motor;

[0013] As a further description of the above technical solution: a second cylinder is fixedly connected to the top of the supporting base plate, and the driving end of the second cylinder is fixedly connected to the outside of the rotating plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the cylinder drives the push bar to slide in the groove, thereby driving the fixed block, rolling shaft, rotating connecting rod and support frame to work together to clamp the steel pipe. This ensures that the clamping force and position are highly consistent each time, effectively avoiding problems such as unstable fixing and skewing of the steel pipe caused by differences in human operation, and laying a solid foundation for subsequent cutting processing.

[0016] 2. In this utility model, when it is necessary to adjust the position of the steel pipe, the pushing roller inside the fixing bar provides an efficient and convenient pushing method. Simply start the roller to rotate, and relying on the friction between it and the surface of the steel pipe, the steel pipe can be easily pushed to slide on the support base plate. Operators do not need to carry the steel pipe with great effort, which reduces labor intensity and avoids problems such as scratches on the surface of the steel pipe that may be caused by manual handling.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a steel pipe cutting and kerf smoothing tool, including a support base plate 1, a slide groove 3 fixedly connected to the top of the support base plate 1, a fixing mechanism provided outside the slide groove 3, a pushing mechanism provided on the top of the support base plate 1, and a cutting component for trimming fixedly connected to the top of the support base plate 1. The support base plate 1 serves as the basic support component for the entire steel pipe cutting and kerf smoothing tool.

[0025] The fixing mechanism includes a cylinder 4, which is externally fixedly connected to the inside of the slide groove 3. A pusher 5 is fixedly connected to the drive end of the cylinder 4. The cylinder 4 is used to push the pusher 5 to slide in the slide groove 3. The slide groove 3 provides a sliding track for the pusher 5. A fixing block 6 is slidably connected to the outside of the pusher 5. Two rolling shafts 7 are slidably connected to the outside of the fixing block 6. The pusher 5 is used to slide along the slide groove 3 under the push of the cylinder 4, which drives the fixing block 6 slidably connected to it to move synchronously. A clamping component for positioning is rotatably connected to the outside of the rolling shafts 7. The fixing block 6 is used to move under the drive of the pusher 5. The rolling shafts 7 on its outside sides can slide along its outside.

[0026] The clamping assembly includes a rotating link 9. Two rotating links 9 are rotatably connected to the outer sides of the rolling shaft 7. The rolling shaft 7 is used to slide along the outer side of the fixed block 6 under the action of the spring and the influence of external force. Its movement drives the rotating link 9 rotatably connected to it to rotate. When the rolling shaft 7 slides, the rotating link 9 rotates around the rotating fixed shaft 8. A rotating ring is provided on the outside of the rotating link 9 so that it can be fixed when the steel pipe rotates. The rotating fixed shaft 8 is rotatably connected to the middle of the two rotating links 9. The rotating fixed shaft 8 is used to provide a rotation support point for the rotating link 9. A support frame 2 is fixedly connected to the outside of the rotating fixed shaft 8. The support frame 2 is used to move closer to the steel pipe under the drive of the rotating link 9. A push column 10 is fixedly connected to the top of the fixed block 6. The push column 10 is used to assist the rotating link 9 in fixing the steel pipe. A spring is sleeved between the two rolling shafts on the outer side of the fixed block 6.

[0027] Reference Figure 1 , Figure 3 and Figure 4 The pushing mechanism includes a fixed bar 11 and a fixed clamping plate 18. The bottom of the fixed bar 11 is fixedly connected to the top of the supporting base plate 1. A pushing roller 12 is rotatably connected inside the fixed bar 11. The fixed bar 11 provides mounting support for the pushing roller 12. The pushing roller 12 is used to generate friction with the surface of the steel pipe through rotation, converting the rotational motion into the linear motion of the steel pipe. The bottom of the fixed clamping plate 18 is fixedly connected to the top of the supporting base plate 1. A rotating shaft 19 is fixedly connected inside the fixed clamping plate 18. The fixed clamping plate 18 is used to provide guidance and support for the movement of the steel pipe by the rotating shaft 19.

[0028] The cutting assembly includes a fixed plate 13, with a rotating plate 14 rotatably connected inside the fixed plate 13. The fixed plate 13 provides rotational support for the rotating plate 14. A motor 15 is fixedly connected to the outside of the rotating plate 14. A repair blade 20 is fixedly connected to the drive end of the motor 15. A protective baffle 17 is fixedly connected to the outside of the motor 15. The rotating plate 14 rotates around the fixed plate 13 under the drive of a second cylinder 16, which moves the motor 15 and the repair blade 20 mounted on its outside. The motor 15 drives the repair blade 20 to rotate at high speed. The repair blade 20 rotates at high speed under the drive of the motor 15 to directly cut and trim the cut edge of the steel pipe. A second cylinder 16 is fixedly connected to the top of the supporting base plate 1. The second cylinder 16 pushes the rotating plate 14. The drive end of the second cylinder 16 is fixedly connected to the outside of the rotating plate 14.

[0029] Working principle: The working area of ​​the steel pipe is pushed by the cylinder 4 to slide the push bar 5 in the slide groove 3. The push bar 5 drives the fixed block 6 to move. When the fixed block 6 moves, it squeezes the spring between the two rolling shafts 7, causing the rolling shafts 7 to slide along the outside of the fixed block 6. The movement of the rolling shafts 7 drives the rotating connecting rod 9 connected to it to rotate around the rotating fixed shaft 8. The rotation of the rotating connecting rod 9 causes the support frame 2 to move closer to the steel pipe until the steel pipe is firmly clamped and positioned. The push column 10 at the top of the fixed block 6 also helps to maintain the fixed state.

[0030] If the steel pipe needs to be moved to a suitable cutting position, the push roller 12 inside the fixing bar 11 starts to rotate, pushing the steel pipe to the appropriate position. After that, the rotating shaft 19 inside the fixing clamp 18 rotates to facilitate the cutting of the repair knife 20. The rotating plate 14 is pushed to rotate inside the fixing plate 13 by starting the cylinder 16, adjusting the motor 15 on the rotating plate 14 and the repair knife 20 to the appropriate cutting position. At the same time, the motor 15 drives the repair knife 20 to rotate at high speed to trim the cut of the steel pipe, making the cut flat and smooth. The protective baffle 17 can prevent the debris generated during the cutting process from flying.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
