Description

Technical Field

[0001] This utility model relates to the field of pipeline production and processing technology, specifically to a pipe body circumferential cutting device for pipeline production. Background Technology

[0002] Pipe cutting refers to the process of cutting a pipe 360° along its outer or inner circumference using mechanical, laser, flame, or other methods to cut the pipe or create a ring-shaped notch of a specific shape in order to produce a pipe of the designed length.

[0003] Current pipeline production methods make it difficult to achieve continuous pipeline cutting. After each pipeline cut, the pipeline position must be manually adjusted before it can be cut again, which is not only cumbersome to operate, but also seriously reduces the efficiency of continuous pipeline cutting. Utility Model Content

[0004] The purpose of this invention is to provide a pipe body circumferential cutting device for pipeline production, so as to solve the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pipe circumferential cutting device for pipe production includes a frame with two rotating rollers rotatably mounted on it. A transmission assembly is also mounted on the frame, including a translation section positioned between the two rotating rollers and a lifting section. The lifting section includes multiple supports fixedly mounted on the translation section, with a lifting frame slidably connected to each support. It also includes a rotating shaft rotatably mounted on the translation section, with eccentric wheels fixedly connected to each support, and the bottom of the lifting frame abutting against the eccentric wheels. Finally, it includes a control section for driving the rotating shaft.

[0007] Furthermore, the translational part includes a screw rotatably mounted on the frame, one end of the screw passing through the frame and fixedly connected to a motor, the motor being fixedly mounted on the frame, a nut seat threadedly connected to the screw, the nut seat being slidably connected to the frame, each of the brackets being fixedly connected to the nut seat, and the rotating shaft being rotatably connected to the nut seat.

[0008] Furthermore, the control unit includes a gear fixedly mounted on a rotating shaft, a rack meshing with the gear, the rack being fixedly connected to the output end of the hydraulic cylinder, and the rack being slidably connected to a nut seat.

[0009] Furthermore, each of the brackets is rotatably connected to two rockers, which are symmetrically arranged. The lifting frame is T-shaped, and two positioning rods corresponding to the rockers are fixedly arranged on the lifting frame. Each positioning rod extends into and is slidably connected to the positioning groove on the corresponding rocker.

[0010] Furthermore, the positioning groove is formed along the length of the rocker arm.

[0011] In the above technical solution, the pipe body circumferential cutting device for pipeline production provided by this utility model has the following beneficial effects:

[0012] The pipe is placed on two rotating rollers by the transmission component. After the cutting machine finishes cutting, the control unit drives the rotating shaft to rotate. The rotation of the rotating shaft drives the eccentric wheel to rotate. The rotation of the eccentric wheel drives the lifting frame that is in contact with it to rise along the support. After it comes into contact with the pipe, it continues to rise, so that the pipe is separated from the rotating roller. The translation unit drives the pipe to move along the frame, so as to complete the continuous cutting of the pipe and effectively improve the cutting efficiency of the pipe.

[0013] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0014] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Please see Figure 1-4 A pipe circumferential cutting device for pipe production includes a frame 1 with two rotating rollers 11 rotatably mounted on it. A transmission assembly is also mounted on the frame 1, including a translation section 2 positioned between the two rotating rollers 11. A lifting section 3 is mounted on the translation section 2, comprising multiple supports 31 fixedly mounted on it. Each support 31 has a lifting frame 32 slidably connected to it. The device also includes a rotating shaft 33 rotatably mounted on the translation section 2, with eccentric wheels 34 fixedly connected to each support 31. The bottom of each lifting frame 32 abuts against the eccentric wheels 34. Finally, a control section 4 for driving the rotating shaft 33 is included. The end of the lifting frame 32 that abuts against the eccentric wheels 34 is arc-shaped.

[0024] Furthermore, the translation part 2 includes a screw 21 rotatably mounted on the frame 1. One end of the screw 21 passes through the frame 1 and is fixedly connected to a motor 22. The motor 22 is fixedly mounted on the frame 1. A nut seat 23 is threadedly connected to the screw 21. The nut seat 23 is slidably connected to the frame 1. Each of the brackets 31 is fixedly connected to the nut seat 23. The rotating shaft 33 is rotatably connected to the nut seat 23.

[0025] Motor 22 drives screw 21 to rotate. Since the nut seat 23 is restricted from rotating by frame 1, the rotation of screw 21 drives nut seat 23 to move along the positive path. The movement of nut seat 23 drives the pipe to move through lifting part 3.

[0026] Furthermore, the control unit 4 includes a gear 41 fixedly mounted on the rotating shaft 33, with a rack 42 meshing with the gear 41. The rack 42 is fixedly connected to the output end of the hydraulic cylinder 43 and slidably connected to the nut seat 23. It can be understood that the output end of the hydraulic cylinder 43 drives the rack 42 to reciprocate via a connecting rod, thereby driving the gear 41 to rotate reciprocally.

[0027] The hydraulic cylinder 43 drives the rack 42 to move, the rack 42 moves to drive the gear 41 to rotate, the gear 41 rotates to drive the rotating shaft 33 to rotate, and can lock the position of the rotating shaft 33 after the rotation is completed, so that the pipeline remains detached from the rotating roller 11 during the movement, reducing resistance and avoiding damage to the outer surface of the pipeline.

[0028] Furthermore, each of the brackets 31 is rotatably connected to two rocker arms 51 at its end. The two rocker arms 51 are symmetrically arranged. The lifting frame 32 is T-shaped, and two positioning rods 52 corresponding to the rocker arms 51 are fixedly arranged on the lifting frame 32. Each positioning rod 52 extends into and is slidably connected to the positioning groove 53 on the corresponding rocker arm 51. The positioning groove 53 is opened along the length direction of the rocker arm 51.

[0029] As the lifting frame 32 moves upward along the support 31, it drives the positioning rod 52 to move. The positioning rod 52 slides within the positioning groove 53, causing the rocker arm 51 to move in a closer direction, thus accommodating the movement of pipes with different outer diameters. It is understood that an arc-shaped block can be fixedly connected to the end of the rocker arm 51 to facilitate better pipe placement.

[0030] Working principle:

[0031] Hydraulic cylinder 43 drives rack 42 to move, rack 42 moves gear 41 to rotate, gear 41 rotates shaft 33 to rotate, shaft 33 rotates to rotate eccentric wheel 34, eccentric wheel 34 rotates to drive lifting frame 32, which is in contact with it, to rise along support 31, and continue to rise after contacting the pipe, so that the pipe is disengaged from rotating roller 11; motor 22 drives screw 21 to rotate, since nut seat 23 is restricted from rotating by frame 1, the rotation of screw 21 drives nut seat 23 to move along the pipe, and the movement of nut seat 23 drives the pipe to move through lifting part 3, thereby completing the automatic feeding of pipe.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
