Description

Technical Field

[0001] This utility model relates to the field of pipeline processing technology, and in particular to a steel pipe extrusion compression device. Background Art

[0002] When connecting multiple steel pipes, connectors are often used to fasten the pipes together. Before installing the connectors, grooves need to be pressed into the joints of the two pipes to allow the head of the connector to fit into the grooves. This also enhances the airtightness of the pipe joints and prevents air and liquid leaks during subsequent use.

[0003] Grooving equipment is typically used to groove steel pipes. However, a typical grooving machine can only groove a specific part of the steel pipe. When the grooving position of the steel pipe changes, the grooving machine must be replaced, which is inconvenient to operate. Utility Model Content

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0027] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0028] This embodiment provides a steel pipe extrusion and compression device for grooving the ends of steel pipes, as described above. Figures 1-3 The system includes a base 1, a rotating mechanism 2, a pressing mechanism 3, and a fixing mechanism 4. The rotating mechanism 2 includes a first driver 21, a rotating shaft 22 driven by the driver, and a rotating part 23 sleeved on the rotating shaft 22. The rotating part 23 is used to position the steel pipe. The rotating part 23 is provided with an annular groove 24. The rotating shaft 22 is also provided with a limiting plate 25. The limiting plate 25 is used to abut and limit the steel pipe. The limiting plate 25 is located on the side of the rotating part 23 near the base 1. The limiting plate 25 is movably connected to the rotating shaft 22 to adjust the interval distance between the limiting plate 25 and the annular groove 24. The system also includes a second driver 31 and a pressing roller 32. The pressing roller 32 is located above the annular groove 24. The second driver 31 is used to drive the pressing roller 32 to move vertically up and down. The fixing mechanism 4 is used to fix the steel pipe on the rotating part 23.

[0029] It should be noted that the limiting plate 25 is used to axially limit the steel pipe, and the fixing mechanism 4 is used to radially limit the pressure roller 32, so that the steel pipe can be stably fitted on the rotating part 23, ensuring the quality of the grooving operation. Therefore, when the position of the limiting plate 25 on the rotating shaft 22 changes, the steel pipe wall corresponding to the annular groove 24 changes accordingly, and grooving can be performed on different parts of the steel pipe.

[0030] In this embodiment, by adjusting the position of the limiting plate 25 on the rotating shaft 22, the pipe wall of the steel pipe corresponding to the annular groove 24 is changed, thereby realizing the grooving operation at different positions of the steel pipe, which has strong applicability.

[0031] During the grooving operation, the steel pipe is fitted onto the rotating part 23, so that the pipe wall is positioned between the pressure roller 32 and the rotating part 23, with one end of the steel pipe abutting against the limiting plate 25. The first driver 21 drives the rotating shaft 22 to rotate, causing the steel pipe fitted onto the rotating part 23 to rotate accordingly. At this time, the second driver 31 drives the pressure roller 32 to descend vertically and contact the steel pipe, pressing down the pipe wall corresponding to the annular groove 24 to achieve grooving of the steel pipe. Simultaneously, when grooving is required at different positions on the steel pipe, the position of the limiting plate 25 on the rotating shaft 22 is adjusted, changing the steel pipe wall corresponding to the annular groove 24, thereby achieving grooving operations at different positions on the steel pipe.

[0032] In this embodiment, the base 1 is hollow inside, the first driver 21 is installed inside the base 1, and the rotating shaft 22 partially protrudes from the base 1.

[0033] In this embodiment, in order to reduce the risk of the steel pipe moving during the grooving operation, the rotating part 23 is cylindrical, and the outer surface of the rotating part 23 is provided with anti-slip grooves. The anti-slip grooves increase the friction between the outer surface of the rotating part 23 and the inner wall of the steel pipe, reducing the risk of the steel pipe sliding on the rotating part 23 and helping to improve the stability of the steel pipe during the grooving operation.

[0034] In this embodiment, a bushing 26 is provided between the limiting disk 25 and the rotating shaft 22. The limiting disk 25 is provided with an axial through hole. The limiting disk 25 is movably sleeved on the bushing 26. The bushing 26 is provided to facilitate the installation of the limiting disk 25 on the rotating shaft 22, and to avoid direct contact between the limiting disk 25 and the rotating shaft 22, thereby protecting the rotating shaft 22.

[0035] In this embodiment, the limiting disk 25 and the bushing 26 can be threaded. Specifically, the axial through hole of the limiting disk 25 is provided with an internal thread, and the bushing 26 is provided with an external thread that engages with the internal thread. The threaded connection provides a stable connection, and the limiting disk 25 can be moved axially along the rotating shaft 22 by rotating the limiting disk 25, which is convenient to operate.

[0036] In this embodiment, the second driver 31 is mounted on the base 1, and a mounting frame 33 is provided between the second driver 31 and the pressure roller 32. The pressure roller 32 is mounted on the mounting frame 33 via a wheel axle 34. The second driver 31 directly controls the vertical lifting and lowering of the mounting frame 33, thereby driving the pressure roller 32 mounted on the mounting frame 33 to lift and lower vertically. Here, the second driver 31 can be a telescopic hydraulic cylinder, with its telescopic end connected to the mounting frame 33. The telescopic hydraulic cylinder can provide a large thrust during operation, which can meet the requirements of the grooving operation.

[0037] In this embodiment, the fixing mechanism 4 includes a fixed base 41, an operating rod 42 disposed on the fixed base 41, a rotating frame 43 that rotates around the fixed base 41, and a fixed wheel 44 rotatably mounted on the rotating frame 43. The rotating frame 43 is disposed on one side of the rotating part 23. One end of the operating rod 42 is connected to the rotating frame 43. The rotating frame 43 is connected to the fixed base 41 via a pin. The operating rod 42 is movably connected to the fixed base 41 to drive the rotating frame 43 to rotate around the fixed base 41, thereby driving the fixed wheel 44 to rotate until it contacts the steel pipe sleeved on the rotating part 23, thereby fixing the steel pipe. Specifically, the fixed base 41 and the operating rod 42 are connected to the rotating part 23. A connecting rod 45 is provided between the two parts. One end of the connecting rod 45 is fixedly connected to the fixed seat 41. The connecting rod 45 has a connecting hole that allows the operating rod 42 to pass through. The operating rod 42 passes through the connecting rod 45 and is threadedly engaged with the connecting rod 45. The operating rod 42 has an external thread, and the wall of the connecting hole has an internal thread that engages with the external thread. Rotating the operating rod 42 will cause the operating rod 42 to move relative to the connecting rod 45, thereby causing the rotating frame 43 to rotate. The threaded engagement makes the connection between the operating rod 42 and the connecting rod 45 relatively tight, thereby improving the stability when the fixed wheel 44 contacts the steel pipe and ensuring the quality of the grooving operation. At the same time, a handle 42a is provided at the end of the operating rod 42 away from the rotating frame 43 for the convenience of the operator.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
