Description

Technical Field

[0001] This utility model relates to the field of steel pipe cutting technology, specifically a steel pipe cutting machine with a fixed structure. Background Technology

[0002] Steel pipe cutting refers to the process of cutting and separating steel pipes according to predetermined dimensions, shapes, and angles using specific tools, equipment, or processes. It is a crucial and common basic process in steel pipe processing and manufacturing.

[0003] In the crucial industry of steel pipe processing, traditional steel pipe cutting operations have long relied on manual operation with simple hand-held cutting tools or versatile but insufficiently specialized cutting equipment. However, this traditional approach has numerous drawbacks. Regarding cutting accuracy, the uncontrollable factors of manual operation and the limitations of simple tools often make it difficult to ensure precise dimensional accuracy in every cut. In terms of cutting efficiency, the overall cutting process is slow due to the limited speed of manual operation and the single function of the equipment, making it difficult to meet the needs of large-scale production or urgent orders. Furthermore, the quality of the cuts is inconsistent; rough cuts not only affect the aesthetics of the steel pipe but may also adversely impact its subsequent processing, connection, and performance, thus hindering the overall development and product quality improvement of the steel pipe processing industry. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel pipe cutting machine with a fixed structure, which can fix steel pipes of different shapes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel pipe cutting machine with a fixed structure, including a U-shaped worktable, wherein a cylinder is mounted on the U-shaped worktable, a mounting plate is fixedly connected to the lower end of the cylinder, the cutting machine body is mounted on the lower surface of the mounting plate, two support seats are mounted on the table surface of the U-shaped worktable, and two fixing mechanisms adapted to the support seats are mounted on the U-shaped worktable.

[0006] Furthermore, the support base includes a U-shaped plate fixedly connected to the table surface of the U-shaped workbench, and a through hole is provided on the upper surface of the U-shaped plate.

[0007] Furthermore, the fixing mechanism includes a cylinder two fixedly connected to the U-shaped workbench, a support plate fixedly connected to the lower surface of the cylinder two, and two triangular blocks fixedly connected to the lower surface of the support plate. The size of the support plate is smaller than the size of the through hole one.

[0008] Furthermore, each of the two triangular blocks has a through hole.

[0009] Furthermore, two connecting plates are fixedly connected between the two support bases, and positioning components are installed on the two connecting plates. The positioning components include two slide rods fixedly connected between the two connecting plates.

The bidirectional threaded rod is rotatably connected to the two connecting plates. Two sliding plates are threadedly connected to the bidirectional threaded rod. Both sliding plates are slidably connected to the slide rod, and a push plate is fixedly connected to the upper surface of both sliding plates.

[0010] Furthermore, the driver is a reversible motor.

[0011] Furthermore, rotatable rollers are installed inside both of the skateboards and on one side of both U-shaped plates.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This type of steel pipe cutting machine with a fixed structure features a unique fixing design that effectively secures steel pipes with various cross-sectional shapes, including circles, triangles, rectangles, and polygons. During the cutting process, the precise fixing method minimizes pipe swaying and displacement, maintaining a stable relative position between the cutting tool and the pipe.

[0018] 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.

[0019] Please see Figures 1 to 3 A steel pipe cutting machine with a fixed structure includes a U-shaped worktable 1. A cylinder 2 is installed on the U-shaped worktable 1. An installation plate 3 is fixedly connected to the lower end of the cylinder 2. A cutting machine body 4 is installed on the lower surface of the installation plate 3. Two support seats are installed on the table surface of the U-shaped worktable 1. Two fixing mechanisms adapted to the support seats are installed on the U-shaped worktable 1.

[0020] like Figures 1 to 3 As shown, when using the steel pipe cutting machine with a fixed structure in this utility model, the steel pipe is placed on two support seats and the position of the steel pipe is adjusted. The fixing mechanism is used to apply downward pressure to the steel pipe to fix steel pipes of different shapes. Then the cutting machine body 4 is started, and the height of the cutting machine body 4 is adjusted by the cylinder 2 to slowly cut the steel pipe.

[0021] like Figure 1 As shown, the support base includes a U-shaped plate 5 fixedly connected to the table surface of the U-shaped workbench 1, and a through hole 6 is provided on the upper surface of the U-shaped plate 5.

[0022] Specifically, the U-shaped plate 5 is used to support the steel pipe, and the through hole 6 is used to accommodate the fixing mechanism, thereby fixing the smaller steel pipe.

[0023] like Figure 2 As shown, the fixing mechanism includes a second cylinder 7 fixedly connected to the U-shaped worktable 1. A support plate 8 is fixedly connected to the lower surface of the second cylinder 7, and two triangular blocks 9 are fixedly connected to the lower surface of the support plate 8. The size of the support plate 8 is smaller than the size of the through hole 6. A pressure sensor is installed inside the second cylinder 7, which can monitor the output pressure in real time and feed the pressure signal back to the control system. The control system compares the signal fed back by the pressure sensor with the preset pressure value. When there is a deviation between the actual pressure and the preset pressure, the control system will automatically adjust the opening of the pressure regulating device (such as a proportional pressure reducing valve or a servo valve) to restore the output pressure to the preset value. For example, when cutting steel pipes of different specifications, the control system can automatically adjust the preset pressure value according to the material, diameter, and other information of the steel pipe, and monitor and adjust the actual pressure in real time through the pressure sensor to ensure that the steel pipe remains stable during the cutting process.

[0024] Specifically, after placing the steel pipe on the U-shaped plate 5, the cylinder 7 is activated, which moves the support plate 8 downward until the two triangular blocks 9 are in contact with the surface of the steel pipe and apply a downward thrust to fix the steel pipe.

[0025] like Figure 2 As shown, both of the two triangular blocks 9 have through holes 10 inside.

[0026] Specifically, through hole 210 reduces the weight of triangle block 9 without affecting its strength.

[0027] As shown in the figure, two connecting plates 11 are fixedly connected between the two support bases. Positioning components are installed on the two connecting plates 11. The positioning components include two sliding rods 12 fixedly connected between the two connecting plates 11. A driver 13 is fixedly connected to the surface of one of the connecting plates 11. A bidirectional threaded rod 14 is fixedly connected to the output end of the driver 13. The bidirectional threaded rod 14 is rotatably connected to the two connecting plates 11. Two sliding plates 15 are threadedly connected to the bidirectional threaded rod 14. Both sliding plates 15 are slidably connected to the sliding rod 12. A push plate 16 is fixedly connected to the upper surface of both sliding plates 15.

[0028] Specifically, after placing the steel pipe on the U-shaped plate 5, the driver 13 is activated. The driver 13 causes the bidirectional threaded rod 14 to rotate, thereby causing the two sliding plates 15 on the bidirectional threaded rod 14 to move simultaneously towards both sides of the steel pipe in opposite directions until the two push plates 16 abut against both sides of the steel pipe. This adjusts the position of the steel pipe so that it is directly below the connection point of the two triangular block 9 components, thus eliminating concerns about deviation in the position of the steel pipe and eliminating the need for manual adjustment of the steel pipe position by the staff.

[0029] like Figure 2 As shown, the driver 13 is a forward and reverse rotating motor.

[0030] Specifically, the forward and reverse motor is used to adjust the rotation direction of the bidirectional threaded rod 14, thereby controlling the direction of movement of the two push plates 16. The forward and reverse motor can monitor the motor's operating current in real time through its internal current sensor. After the two push plates 16 come into contact with the two sides of the steel pipe and affect the rotation of the bidirectional threaded rod 14, the forward and reverse motor will automatically disconnect.

[0031] like Figure 1 and Figure 2 As shown, rotatable rollers 17 are installed inside the two slide plates 15 and on one side of the two U-shaped plates 5.

[0032] Specifically, the roller 17 facilitates the movement of the steel pipe, saving the physical effort of the workers.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
