[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: a cutting device for seamless steel pipe production, including a frame 1, a fixed plate 2 is installed on the top of the frame 1, and a first motor 3 is arranged on the outer wall of the fixed plate 2.

[0027] The specific implementation method is as follows: By setting the adjusting frame 10, the measuring tape 14 and the second adjusting plate 17, the first cylinder 16 drives the second adjusting plate 17 and the second positioning roller 18 to position the seamless steel pipe. Then, the threaded rod 11 drives the limiting plate 13 for threaded adjustment to position the cutting length of the seamless steel pipe, solving the problem that the existing cutting device for seamless steel pipe production is not convenient for workers to accurately cut and quickly cut materials of seamless steel pipes with different lengths. Thus, it is convenient for workers to cut and cut materials of seamless steel pipes with different lengths, saving the time for workers to cut and cut materials of seamless steel pipes with different lengths. At the same time, it prevents certain deviations from occurring when the seamless steel pipe is cut into different lengths, and further ensures the quality of the seamless steel pipe used by workers subsequently.

[0028] Please refer to Figures 1-2 , the present utility model provides a technical solution: A cutting device for seamless steel pipe production. The top of the frame 1 is fixedly connected with a first support frame 15, and a first cylinder 16 is arranged on the top of the first support frame 15. The bottom end of the first cylinder 16 is fixedly connected with a second adjusting plate 17, and the outer wall of the second adjusting plate 17 is connected with a second positioning roller 18 by a bearing. The top of the frame 1 is fixedly connected with a first fixing frame 19, and the outer wall of the first fixing frame 19 is connected with a bearing frame 20 by a bearing. The outer wall of the bearing frame 20 is fixedly connected with a support plate 21. A second motor 22 is installed on the top of the support plate 21, and the output shaft of the second motor 22 is connected with a transmission rod 23 through a coupling. A transmission device 24 is arranged on the outer wall of the transmission rod 23, and a fixing rod 25 is arranged on the inner wall of the transmission device 24. The other end of the fixing rod 25 is fixedly connected with a cutting device 26. One side of the support plate 21 is fixedly connected with a second support frame 30.

[0029] The second adjusting plate 17 forms a lifting structure through the first cylinder 16, and the inner wall of the second adjusting plate 17 is slidably connected with the first support frame 15. The second positioning roller 18 and the second adjusting plate 17 form an integrated structure, and the centers of the second adjusting plate 17 and the two first positioning rollers 8 are on the same vertical line;

[0030] The top of the frame 1 is fixedly connected with a second fixing frame 27, and the outer wall of the second fixing frame 27 is connected with a second cylinder 28 by a bearing. The other end of the second cylinder 28 is fixedly connected with an installation ring 29, and the inner wall of the installation ring 29 is fixedly connected with a second support frame 30. The installation ring 29 forms a telescopic structure through the second cylinder 28.

[0031] The specific implementation method is as follows: By means of the fixed plate 2, the first adjusting plate 7 and the second cylinder 28, the second lead screw 6 and the first lead screw 4 are used to rotate in opposite threads to drive the two first adjusting plates 7 to adjust relatively. Then, in cooperation with the second cylinder 28, the mounting ring 29 and the second support frame 30 are driven to perform telescopic adjustment. At this time, the support plate 21 drives the cutter 26 to rotate along the first fixing frame 19 through the bearing frame 20, completing the positioning cutting of seamless steel pipes of different sizes. Thus, it is convenient for the staff to perform positioning cutting on seamless steel pipes of different sizes, improving the efficiency of the staff in cutting seamless steel pipes of different sizes. At the same time, through the bearing connection of the two first positioning rollers 8 and the second positioning rollers 18, the seamless steel pipe rotates during cutting, thereby ensuring the stability of the staff when cutting the seamless steel pipe.

[0032] Working principle: When using this cutting device for seamless steel pipe production, first place the seamless steel pipe above the fixed plate 2. Then, by starting the first motor 3, the first motor 3 drives the first lead screw 4 to rotate at this time. Since both ends of the connecting rod 5 are fixedly connected to the second lead screw 6 and the first lead screw 4, and the second lead screw 6 and the first lead screw 4 are set with opposite threads, the second lead screw 6 and the first lead screw 4 drive the two first adjusting plates 7 threadedly connected to the outer wall to move relatively, thereby driving the first adjusting plates 7 to slide along the slide rail 9. Furthermore, the first positioning rollers 8 connected to the outer wall of the first adjusting plates 7 by bearings are used to position seamless steel pipes of different specifications.

[0033] Then, by rotating the regulating valve 12, the regulating valve 12 drives the threaded rod 11 to perform threaded lifting along the adjusting frame 10 at this time, so that the threaded rod 11 drives the limiting plate 13 to perform synchronous adjustment. Thus, the measuring tape 14 is stretched by the limiting plate 13, and then the length of the limiting plate 13 is adjusted. Then, by subtracting the length of the limiting plate 13 after adjustment from the length between the fixed plate 2 and the limiting plate 13, the length required for cutting the seamless steel pipe is obtained. Then, by pushing the seamless steel pipe, the seamless steel pipe is brought into contact with the limiting plate 13. At this time, by starting the first cylinder 16, the first cylinder 16 drives the second adjusting plate 17 to rise and fall.

[0034] The second positioning rollers 18 are driven by the second adjusting plate 17 to position the seamless steel pipe. Immediately afterwards, by starting the second motor 22 installed on the top of the support plate 21, the second motor 22 drives the transmission rod 23 to rotate at this time, so that the transmission 24 drives the fixed rod 25 to rotate following the transmission rod 23. The cutter 26 is driven to rotate by the fixed rod 25. Thus, by starting the second cylinder 28, the mounting ring 29 is driven to perform telescopic adjustment by the fixed rod 25.

[0035] At this time, the installation ring 29 pushes the support plate 21 through the second support frame 30, so that the support plate 21 drives the bearing frame 20 to rotate along the first fixing frame 19 to complete the position adjustment of the cutter 26. The second cylinder 28 rotates along the second fixing frame 27 to ensure the stability of the telescopic adjustment of the second cylinder 28 driving the installation ring 29, thereby driving the cutter 26 to cut the seamless steel pipe. Furthermore, the first cylinder 16 is used to make the cut seamless steel pipe slide along the discharge chute 31, and at the same time, the seamless steel pipe is pushed to continuously cut the seamless steel pipe of a specified length subsequently.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
