Description
Technical Field
[0001] This utility model belongs to the field of pipe cutting technology, and more specifically, it relates to a pipe cutting device. Background Technology
[0002] A pipe cutting device is a tool used to cut pipes made of metal, plastic, fiberglass, etc. It typically consists of an electric motor or pneumatic drive system, a cutting head, and a control system. When using a pipe cutting device, the operator needs to make the correct settings and adjustments according to the cutting target and the pipe material. Then, the operator uses the control system to start the cutting head and adjusts the cutting speed and depth as needed. As the cutting head rotates, the blades cut the pipe through friction and cutting force, thus completing the cutting task.
[0003] A search revealed that patent CN222370517U discloses a pipe cutting device, including a cutting machine table and a cutting support mechanism. A cutting blade is installed on the rear side of the top of the cutting machine table, and a protective cover is installed on the top of the cutting machine table outside the cutting blade. A fixed base is fixedly connected to both sides of the top of the cutting machine table, and a support base is movably connected to the top of the fixed base. A lifting base is movably connected to the top of the support base. By setting up a cutting support mechanism, the pipe being cut can be clamped and supported when the operator cuts the external pipe with the cutting blade. At the same time, the rotating groove and the rotating ball enable rotational connection between the pipe and the support base and the lifting base, facilitating the operator to rotate the pipe to achieve circular cutting. This avoids situations where it is difficult to support the pipe during circular cutting, thus improving the convenience and cutting effect of pipe cutting.
[0004] In the aforementioned patents, when cutting the pipe at multiple ends, the pipe is held in place and needs to be loosened and its position adjusted, which is inconvenient. In addition, the cutting can only be done vertically, which is inconvenient if the pipe needs to be cut at an angle. Therefore, a pipe cutting device is designed to solve the above problems.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] Please see Figures 1 to 6This utility model provides a technical solution: a pipe cutting device, including a horizontal placement plate 1, a second vertical sliding column 7 fixedly installed on the upper end of the horizontal placement plate 1, and a horizontal sliding frame 3 fixedly installed on it. A first vertical sliding column 4 is slidably installed inside the horizontal sliding frame 3. Under the action of external force, the first vertical sliding column 4 will slide on the horizontal sliding frame 3. At this time, the first vertical sliding column 4 will move closer to the second vertical sliding column 7, thus facilitating the subsequent clamping of the pipe.
[0028] In this embodiment, please refer to Figure 1 A first clamping rod 5 is fixedly connected to the bottom surface of the side of the first vertical sliding column 4. A second clamping rod 6 is slidably installed in the sliding groove of the side wall of the first vertical sliding column 4. Under the action of external force, the second clamping rod 6 and the first clamping rod 5 will move closer to each other, which facilitates the subsequent clamping of the pipe.
[0029] In this embodiment, please refer to Figure 1 A third clamping rod 8 is fixedly connected to the bottom side surface of the second vertical sliding column 7, and a fourth clamping rod 10 is slidably installed in the sliding groove of the side wall of the second vertical sliding column 7. Under the action of external force, the third clamping rod 8 and the fourth clamping rod 10 will move closer to each other, which facilitates the subsequent clamping of the pipe.
[0030] In this embodiment, please refer to Figure 6 Multiple rolling devices are provided on the surfaces of the first clamping rod 5, the second clamping rod 6, the third clamping rod 8, and the fourth clamping rod 10. For example, a U-shaped mounting base 32 is fixedly installed on the surface of the first clamping rod 5. The rotating shaft 34, which is rotatably installed inside the U-shaped mounting base 32, can rotate the fixed rod 35 fixedly connected to its end. The end of the fixed rod 35 is fixedly connected to a rectangular frame 37. A semi-circular groove 33 is opened on the side surface of the U-shaped mounting base 32. The angle of the semi-circular groove 33 is 45 degrees, and one side is vertical. Thus, the sliding rod fixedly connected to the side of the rectangular frame 37... The tube 36 can slide inside the semi-circular groove 33. At this time, the rectangular frame 37 can rotate to a horizontal and a 45-degree angle. When it is at a 45-degree angle, the roller 38 mounted on the rectangular frame 37 also maintains a 45-degree angle. At this time, the rolling devices of the first clamping rod 5, the second clamping rod 6, the third clamping rod 8 and the fourth clamping rod 10 all maintain a 45-degree angle, which can just hold the round tube and ensure the clamping effect. At the same time, the pipe can also be moved by the effect of the roller 38, which is convenient for multi-end cutting. The clamping device can also be angled to clamp square tubes and round tubes.
[0031] In this embodiment, please refer to Figure 2A turntable 13 is fixedly connected to the upper surface of the horizontally placed plate 1, and a C-shaped fixing seat 14 is fixedly connected to the upper surface of the turntable 13. Under the action of the turntable 13, the C-shaped fixing seat 14 can rotate, which facilitates subsequent angle cutting. A hydraulic cylinder 15 is fixedly installed on the upper surface of the inner wall of the C-shaped fixing seat 14. A cutting machine 16 is fixedly connected to the kinetic energy output end of the hydraulic cylinder 15. The hydraulic cylinder 15 can drive the cutting machine 16 to move up and down, ensuring that the pipe can be cut in the future.
[0032] In this embodiment, please refer to Figure 5 A first small cylinder 27 is rotatably mounted on the upper end of the horizontally placed plate 1. An electric push rod 28 is fixedly connected to the upper surface of the first small cylinder 27. The electric push rod 28 moves the second small cylinder 29 on the C-shaped fixed seat 14. The second small cylinder 29 rotates with the C-shaped fixed seat 14. Therefore, the electric push rod 28 can rotate the C-shaped fixed seat 14.
[0033] In this embodiment, please refer to Figure 5 A protractor 30 is fixedly installed on the upper surface of the horizontally placed plate 1, and a pointer 31 is fixedly connected to the side surface of the C-shaped fixing seat 14. By the angle change between the pointer 31 and the protractor 30, the angle between the cutting machine 16 and the pipe cutting can be known.
[0034] In this embodiment, please refer to Figure 4 An operating box 19 is fixedly connected to the upper surface of the horizontally placed plate 1. A connecting rod 21 is rotatably installed inside the operating box 19. Rotating the handle 22 at the end of the connecting rod 21 causes the connecting rod 21 and the horizontal threaded rod 20 fixedly connected to its end to rotate. The horizontal threaded rod 20 is threadedly connected to the first vertical sliding column 4. Therefore, the first vertical sliding column 4 moves left and right under the action of the horizontal threaded rod 20 and the horizontal sliding frame 3, which facilitates subsequent clamping.
[0035] In this embodiment, please refer to Figure 4 Inside the operating box 19, a threaded collar 24 is fixedly installed. A vertical threaded rod 26 is threadedly connected inside the threaded collar 24. A bent rod 9 is threadedly connected to the end of the vertical threaded rod 26. A long groove 11 is opened on the bent rod 9, and the slider 12 at the upper end of the second clamping rod 6 slides in the long groove 11. Therefore, under the action of the vertical threaded rod 26, the bent rod 9 will move up and down, thus carrying the second clamping rod 6 and the fourth clamping rod 10 up and down, which facilitates subsequent clamping.
[0036] In this embodiment, please refer to Figure 4The surface of the connecting rod 21 is fixedly connected to the first helical gear 23, and the surface of the vertical threaded rod 26 is fixedly connected to the second helical gear 25. Under the action of gear meshing, by turning the handle 22, the horizontal threaded rod 20 and the vertical threaded rod 26 can be rotated at the same speed. At this time, the first clamping rod 5, the second clamping rod 6, the third clamping rod 8 and the fourth clamping rod 10 are at the same distance from each other, so they can clamp the round tube.
[0037] In this embodiment, please refer to Figure 1 and Figure 3 The horizontal placement plate 1 has a placement slot 17 on its side surface. A collection bin 18 is installed inside the placement slot 17. A baffle 39 is fixedly installed on the upper surface of the horizontal placement plate 1. The cut debris is blocked by the baffle 39 and can fall into the collection bin 18. Other debris that falls on the horizontal placement plate 1 can be swept into the collection bin 18 for convenient centralized processing. A support leg 2 is fixedly connected to the bottom surface of the horizontal placement plate 1 to support the entire device.
[0038] The specific usage and function of this embodiment are as follows:
[0039] By rotating the handle 22, the connecting rod 21 rotates. Under the action of the first helical gear 23 and the second helical gear 25, the horizontal threaded rod 20 and the vertical threaded rod 26 can be rotated. Then, under the action of the bent rod 9, the horizontal slide frame 3, the first vertical slide column 4 and the second vertical slide column 7, the first clamping rod 5, the second clamping rod 6, the third clamping rod 8 and the fourth clamping rod 10 are brought closer together. Then, through the action of the roller 38, the pipe can be clamped, and under the action of the roller 38, the pipe can be moved left and right, which is convenient for multi-segment cutting. At the same time, under the action of the electric push rod 28, the C-shaped fixing seat 14 can be rotated. At this time, the angle between the hydraulic cylinder 15 at the bottom of the C-shaped fixing seat 14 and the cutting machine 16 and the pipe can be adjusted, which can perform angle cutting on the pipe, increasing practicality. At the same time, under the action of the hydraulic cylinder 15, the cutting machine 16 can also move up and down, which can ensure complete cutting of the pipe and ensure the cutting effect.
