Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe straightening technology, specifically to a seamless steel pipe straightening device that prevents collapse. Background Technology

[0002] Seamless steel pipes are made by piercing a whole round steel bar. They are steel pipes without weld seams on the surface. Seamless steel pipes are generally not long, have high quality requirements, and are used in many important fields. During the production process of seamless steel pipes, it is often necessary to straighten them.

[0003] For example, the announcement number CN218224373U is titled "A Cold-Drawn Seamless Steel Pipe Straightening Machine Processing Positioning Mechanism." This device includes a processing plate, with vertical plates fixedly connected to the upper surface of the processing plate at symmetrical positions on the left and right sides. A groove is formed at the top of the vertical plate, and a rectangular rod is fixedly connected to the inner bottom of the groove. A hollow rectangular cylinder is slidably connected to the outer surface of the rectangular rod. A connecting rod is provided at the top of the hollow rectangular cylinder, and sliding grooves are formed at symmetrical positions on the bottom surface of the connecting rod. A slider is provided inside the sliding groove, and one side of the slider is fixedly connected to the top of the hollow rectangular cylinder.

[0004] The aforementioned device causes slight deformation and collapse of the steel pipe wall during use, resulting in unsatisfactory straightening quality. It cannot be adjusted and fixed according to the length of the steel pipe, thus limiting its application. Furthermore, it cannot guarantee the tightness of the steel pipe compression, failing to fully meet the requirements. Therefore, we propose an anti-collapse seamless steel pipe straightening device to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a straightening device for seamless steel pipes that prevents collapse, in order to solve the problems mentioned in the background art. Existing positioning devices for straightening steel pipes cause slight deformation and collapse of the pipe wall during use, resulting in unsatisfactory straightening quality. They cannot be adjusted and fixed according to the length of the steel pipe, which limits their use. They also cannot guarantee the tightness of the steel pipe compression, and cannot fully meet the requirements.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a straightening device for seamless steel pipes to prevent collapse, comprising a workbench, a moving device mounted on the top of the workbench, a vertical plate mounted on the top of the moving device, a fixed frame mounted on the right side of the upper part of the vertical plate, a second rotating motor mounted on the left side of the upper part of the vertical plate, the fixed frame and the second rotating motor connected by a rotating shaft, a bidirectional threaded rod mounted at one end inside the fixed frame, a handle mounted on the top of the bidirectional threaded rod passing through the upper plate of the fixed frame, first clamping plates symmetrically mounted at both ends of the outer wall of the bidirectional threaded rod, a fixed rod mounted at the center of the right side of the fixed frame, a plurality of first cylinders evenly mounted on the outer wall of the right side of the fixed rod, an abutment plate mounted at the other end of the first cylinder, a fixed seat mounted on the right side of the moving device, a through hole provided inside the fixed seat, an annular plate mounted on the inner wall of the through hole, second cylinders mounted around the inner wall of the annular plate, a second clamping plate mounted at the other end of the second cylinder, a support plate mounted on the upper part of the right side of the moving device, and the two ends of the bottom of the support plate fixedly connected to the workbench by hydraulic cylinders.

[0007] Preferably, the moving device includes a fixed plate, a threaded rod, a first rotating motor, and a slider. The fixed plates are installed on both sides of the top of the worktable. The threaded rod is located between the two fixed plates. The first rotating motor is installed on the right side of the threaded rod through the fixed plate. The slider is slidably installed on the outer wall of the threaded rod. The upright plate is installed on the top of the slider.

[0008] Preferably, a limiting rod is installed at the front end of the threaded rod, and the slider is slidably connected to the limiting rod.

[0009] Preferably, a slide rod is installed at the other end of the fixing frame, and the slide rod is slidably installed at the other end of the first clamping plate.

[0010] Preferably, a plurality of linear bearings are evenly installed on the outer wall of the right side of the fixing rod. The linear bearings are located on the right side of the first cylinder, and the other end of the linear bearings is fixedly connected to the abutment plate.

[0011] Preferably, the fixed base has a T-shaped arc groove inside, and a T-shaped limiting block is movably installed inside the T-shaped arc groove. The other end of the T-shaped limiting block is fixedly connected to the annular plate.

[0012] Preferably, the top of the support plate is provided with a placement groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model uses a first rotating motor to drive the threaded rod to rotate, causing the slider to move. The vertical plate drives the fixing frame to move, which can be adjusted and fixed according to the length of the steel pipe. By rotating the handle, the bidirectional threaded rod rotates, causing the two first clamping plates to move closer to each other until they are in contact with the surface of the steel pipe, which can clamp and fix one end of the steel pipe. The first cylinder drives the abutment plate to move until it is in contact with the inner wall of the steel pipe, which can fix the steel pipe from the inside and prevent the steel pipe wall from deforming. The second cylinder drives the second clamping plate to move until it is in contact with the outer wall of the steel pipe, which can clamp and fix the other end of the steel pipe. This solves the problems of existing positioning devices for straightening steel pipes causing slight deformation and collapse of the steel pipe wall during use, resulting in unsatisfactory straightening quality, inability to adjust and fix according to the length of the steel pipe, certain limitations in use, and inability to guarantee the tightness of the steel pipe clamping, thus failing to fully meet the requirements.

[0015] (2) The second rotating motor can drive the fixed frame to rotate under the action of the rotating shaft. The steel pipe can be driven to rotate through the first clamping plate and the abutment plate. The second clamping plate can generate a rotational force on the ring plate. The ring plate can be rotated by the combined action of the T-shaped arc groove and the T-shaped limit block. The rotation of the steel pipe can ensure that the steel pipe is subjected to uniform force in the straightening device, so that its shape and size can be accurately adjusted.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4This utility model provides an embodiment of a seamless steel pipe straightening device to prevent collapse, comprising a workbench 1, a moving device mounted on the top of the workbench 1, the moving device comprising a fixed plate 2, a threaded rod 3, a first rotating motor 4, and a slider 5, fixed plates 2 mounted on both sides of the top of the workbench 1, the threaded rod 3 located between the two fixed plates 2, the first rotating motor 4 mounted on the right side of the threaded rod 3 via the fixed plate 2, the slider 5 slidably mounted on the outer wall of the threaded rod 3, a vertical plate 7 mounted on the top of the slider 5, a vertical plate 7 mounted on the top of the moving device, a fixed frame 8 mounted on the upper right side of the vertical plate 7, a second rotating motor 9 mounted on the upper left side of the vertical plate 7, the fixed frame 8 and the second rotating motor 9 connected by a rotating shaft 10, and a double-ended rotating motor 9 mounted on one end inside the fixed frame 8. A handle 12 is installed on the top of the threaded rod 11, which passes through the upper plate of the fixed frame 8. First clamping plates 13 are symmetrically installed at both ends of the outer wall of the double-threaded rod 11. A sliding rod 14 is installed at the other end inside the fixed frame 8. The sliding rod 14 is slidably installed at the other end of the first clamping plate 13. A fixed rod 15 is installed at the center of the right side of the fixed frame 8. Several first cylinders 16 are evenly installed on the outer wall of the right side of the fixed rod 15. An abutment plate 17 is installed at the other end of each first cylinder 16. A fixed seat 19 is installed on the right side of the moving device. A through hole 20 is provided inside the fixed seat 19. An annular plate 23 is installed on the inner wall of the through hole 20. A T-shaped arc groove 21 is provided inside the fixed seat 19. A T-shaped limiting block 2 is movably installed inside the T-shaped arc groove 21. 2. The other end of the T-shaped limiting block 22 is fixedly connected to the annular plate 23. A second cylinder 24 is installed around the inner wall of the annular plate 23. A second clamping plate 25 is installed at the other end of the second cylinder 24. A support plate 27 is installed on the upper right side of the moving device. The two ends of the bottom of the support plate 27 are fixedly connected to the worktable 1 through hydraulic cylinders 26. The first rotating motor 4 drives the threaded rod 3 to rotate, causing the slider 5 to move. This, in turn, drives the fixing frame 8 to move through the upright plate 7. The length of the steel pipe can be adjusted and fixed. One end of the steel pipe is placed between the two first clamping plates 13, and the fixing rod 15 enters the steel pipe. The other end of the steel pipe is placed on the support plate 27. By rotating the handle 12, the bidirectional threaded rod 11 is rotated, causing the two first clamping plates 13 to move closer to each other. The first clamping plate 13 is held in place until it comes into contact with the surface of the steel pipe, thus clamping and fixing the steel pipe. The limiting action of the sliding rod 14 ensures that the first clamping plate 13 always moves vertically, improving the stability of the steel pipe clamping. The height of the support plate 27 is adjusted by the hydraulic cylinder 26 to keep the steel pipe horizontal. The first cylinder 16 moves the abutment plate 17 until it comes into contact with the inner wall of the steel pipe, thus fixing the steel pipe from the inside and preventing deformation of the pipe wall. The moving device moves the steel pipe to the right to enter the through hole 20. The second cylinder 24 moves the second clamping plate 25 until it comes into contact with the outer wall of the steel pipe, thus clamping and fixing the other end of the steel pipe, improving the stability of the steel pipe positioning. The second rotating motor 9 drives the fixing frame 8 to rotate via the rotating shaft 10.The steel pipe can be rotated by the first clamping plate 13 and the abutment plate 17. The second clamping plate 25 provides a rotational force to the annular plate 23. The combined action of the T-shaped arc groove 21 and the T-shaped limiting block 22 allows the annular plate 23 to rotate accordingly. This rotation ensures the steel pipe receives uniform force within the straightening device, resulting in precise adjustment of its shape and size, thus improving the practicality of the positioning device. The support plate 27 provides support for the steel pipe, preventing bending due to gravity and facilitating subsequent straightening operations.

[0023] Please see Figure 3 A limiting rod 6 is installed at the front end of the threaded rod 3. The slider 5 is slidably connected to the limiting rod 6. The limiting rod 6 can keep the slider 5 horizontal at all times, which improves the stability and transmission efficiency of the slider 5, thereby improving the stability and accuracy of the steel pipe positioning.

[0024] Please see Figure 2 and Figure 3 Several linear bearings 18 are evenly installed on the outer wall of the right side of the fixing rod 15. The linear bearings 18 are located on the right side of the first cylinder 16. The other end of the linear bearings 18 is fixedly connected to the abutment plate 17. The linear bearings 18 can make the abutment plate 17 always move in a straight line, so as to avoid the abutment plate 17 from tilting and affecting the positioning effect of the steel pipe.

[0025] Please see Figure 3 The top of the support plate 27 is provided with a placement groove 28, in which the seamless steel pipe can be placed. Since the seamless steel pipe is cylindrical and is affected by gravity, the seamless steel pipe can be slowly stabilized in the middle of the inner wall of the placement groove 28.
