Description

Technical Field

[0001] This utility model relates to the field of stainless steel processing technology, specifically to a stainless steel test pile pipe cutting machine. Background Technology

[0002] Stainless steel test piles are widely used in the pipeline transportation of oil and natural gas, as well as in projects requiring the protection and monitoring of metal pipelines. These test piles are used to detect parameters such as cathodic protection potential and current of pipelines to ensure their safe operation. Cutting the steel pipe is a crucial step in the production of these test piles.

[0003] Referring to the existing Chinese patent with publication number CN219944973U, a laser tube cutting machine is disclosed, specifically relating to the field of tube cutting machine technology. This utility model includes a machine base, and the supporting device includes a groove rod. One end of the outer surface of the groove rod slides on the inner wall of the groove. A sliding rod is slidably connected to the inner wall of the groove rod. A U-shaped block is fixedly connected to the top of the outer surface of the sliding rod. A threaded rod is fixedly connected to one side of the outer surface of the U-shaped block. A threaded ring is threadedly connected to the outer surface of the threaded rod.

[0004] The aforementioned laser pipe cutting machine, by incorporating a U-shaped block, allows for adjustment of the U-shaped block's height by sliding a sliding rod along the inner wall of the grooved rod during pipe cutting. Rotating the threaded ring moves it along the outer surface of the threaded rod, pressing it against the outer surface of the grooved rod to fix the U-shaped block's height. Placing the side of the pipe furthest from the fixing head within the groove on the outer surface of the U-shaped block provides support, preventing the pipe from becoming skewed and affecting its entry into the cutting head. However, this laser pipe cutting machine still has some drawbacks. For example, during laser cutting of pipe surfaces, due to the relatively long overhang of the pipe, dimensional deviations are easily caused by vibration, especially at the end of the cutting process.

[0031] 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.

[0032] Please see Figures 1-8 This utility model provides a technical solution:

[0033] A stainless steel test pile pipe cutting machine, comprising:

[0034] Operating platform 1, on which a hopper 2 is installed, and a discharge channel 3 is provided on the hopper 2. A feeding assembly is provided on the discharge channel 3. The feeding assembly includes a drive motor 11, a rotating rod 12 and a feeding roller 13. The feeding roller 13 is rotatably connected in the discharge channel 3 and a feeding groove 14 is opened on the feeding roller 13. The drive motor 11 is installed on the discharge channel 3, and the output end of the drive motor 11 is connected to one end of the feeding roller 13 through the rotating rod 12. An infrared sensor 4 is installed on one side of the discharge channel 3.

[0035] When the pipe is placed in the feeding hopper 2, the controller 32 starts the drive motor 11. The drive motor 11 drives the feeding roller 13 to rotate through the rotating rod 12. Since the feeding roller 13 has a feeding groove 14, the pipe falls into the feeding groove 14 in sequence as the feeding roller 13 rotates. The feeding roller 13 drives the pipe to move and feed, realizing automatic and orderly feeding. The infrared sensor 4 monitors the status of the pipe in the feeding hopper 2 in real time and feeds the signal back to the controller 32 to avoid empty cutting or accidental cutting.

[0036] The operating platform 1 is connected to a first lower clamping plate 6 via an electric slide table 5. The other end of the electric slide table 5 is connected to a second lower clamping plate 7. The first lower clamping plate 6 and the second lower clamping plate 7 are provided with clamping components. The clamping components include a second support frame 15, a first electric push rod 16 and a side clamping plate 17. The second support frame 15 is fixedly connected to both sides of the first lower clamping plate 6 and the second lower clamping plate 7. The first electric push rod 16 is fixedly installed on the second support frame 15, and the output end of the first electric push rod 16 is connected to the side clamping plate 17. A baffle 8 is fixedly provided on one side of the first lower clamping plate 6.

[0037] Furthermore, mounting grooves 18 are provided on the first lower clamping plate 6, the second lower clamping plate 7, and the side clamping plate 17. Several sliding rods 19 are rotatably connected in the mounting grooves 18. The sliding rods 19 can prevent the pipe from rotating when it rotates.

[0038] When clamping the pipe fitting, the electric slide table 5 operates, driving the first lower clamping plate 6 and the second lower clamping plate 7 to move and adjust to a suitable distance to accommodate the pipe fitting length. The pipe fitting is then transported and falls onto the first lower clamping plate 6 and the second lower clamping plate 7. Subsequently, the first electric push rod 16 is activated, pushing the side clamping plate 17 towards the pipe fitting. The slide rod 19, which is rotatably connected to the first lower clamping plate 6, the second lower clamping plate 7, and the mounting groove 18 on the side clamping plate 17, fits tightly against the pipe fitting, firmly clamping it. The baffle 8 on one side of the first lower clamping plate 6 limits one end of the pipe fitting to prevent axial displacement during the cutting process. The electric slide table 5 can drive the first clamping plate 25 to move, pushing the clamped pipe fitting towards the cutting position, reducing manual intervention.

[0039] An adjustment mechanism for rotating pipe fittings is installed on the operating platform 1. The adjustment mechanism includes a support frame 20, a servo motor 21, a gear disk 22, a rotating ring 23, a second electric push rod 24, and a clamping plate 25. The support frame 20 is fixedly installed on the operating platform 1 and has a through hole 26. The rotating ring 23 is rotatably connected inside the support frame 20. The second electric push rod 24 is installed on the rotating ring 23 and its output end is connected to the clamping plate 25. The servo motor 21 is installed on the support frame 20 and its output end is connected to the gear disk 22. The rotating ring 23 has toothed edges 27 that mesh with the gear disk 22. Limiting rings 28 are provided on both sides of the rotating ring 23. A limiting groove 29 is provided on the support frame 20, and the limiting ring 28 is rotatably connected inside the limiting groove 29.

[0040] When the pipe is clamped and pushed to the appropriate position, the controller 32 controls the servo motor 21 to start. The servo motor 21 drives the gear disk 22 to rotate. Since the rotating ring 23 is provided with toothed edges 27 that mesh with the gear disk 22, the rotation of the gear disk 22 drives the rotating ring 23 to rotate within the support frame 20. The limiting rings 28 on both sides of the rotating ring 23 rotate within the limiting grooves 29 to ensure the stable rotation of the rotating ring 23. The second electric push rod 24 on the rotating ring 23 pushes the clamping plate 25 to clamp one end of the pipe. As the rotating ring 23 rotates, one end of the pipe can be firmly fixed and the pipe can be rotated, so that the pipe is subjected to uniform force during cutting and the cutting accuracy is ensured.

[0041] A laser cutting head 10 is mounted on the operating platform 1 via a first support frame 9. A servo electric cylinder 30 is fixedly mounted on the first support frame 9. The output end of the servo electric cylinder 30 is connected to a support plate 31. The laser cutting head 10 is mounted on the support plate 31.

[0042] During the cutting process, the servo electric cylinder 30 moves up and down according to the instructions of the controller 32, thereby adjusting the height of the laser cutting head 10 so that it is aligned with the cutting position of the pipe. The controller 32 controls the laser cutting head 10 to start and perform the cutting operation on the pipe.

[0043] In the above embodiment, a controller 32 is installed on the operating platform 1. The controller 32 is electrically connected to the infrared sensor 4, the electric slide table 5, the laser cutting head 10, the drive motor 11, the first electric push rod 16, the servo motor 21, and the servo electric cylinder 30.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
