Description

Technical Field

[0001] This utility model belongs to the field of pipe cutting technology, specifically relating to a long pipe cutting device. Background Technology

[0002] In numerous fields such as construction, decoration, machinery manufacturing, and pipeline installation, long pipe cutting is a common and crucial operational step. Whether it's steel pipes used for building structures, plastic pipes in decoration projects, or long metal pipes in machinery manufacturing, precise cutting is required to meet the size and shape requirements of different scenarios. However, traditional long pipe cutting tools and methods have many problems in practical applications, failing to meet the demands of modern construction and production for efficient, convenient, and high-quality cutting. Traditional long pipe cutting tools, such as large benchtop cutting machines, are bulky, heavy, and have a fixed structure that cannot be folded or stored. At construction sites, especially where frequent changes in work locations are necessary, moving these large pieces of equipment is extremely inconvenient. Traditional cutting methods often lack effective support and restraint structures, causing long pipes to easily sway or shift during cutting. For example, when using handheld cutting tools for long pipe cutting, the operator's limited hand stability makes it difficult to ensure the cutting blade always cuts along the predetermined cutting line, easily resulting in uneven cut surfaces and large dimensional deviations, affecting subsequent installation and use.

A fixing frame 19 is welded to the lifting rod 5, and a saw blade 17 and a motor are mounted on the fixing frame 19. A lifting groove 18 is vertically formed on the fixing post 15, and the fixing frame 19 slides through the lifting groove 18.

[0026] Working principle: Folding and unfolding of support platform 1:

[0027] The support platform 1 of this long tube cutting device features a foldable design. When the device is needed, the support platform 1 is unfolded, at which point the support legs 3 provide stable support for the device. After use, the support platform 1 can be folded to reduce the size of the device, making it convenient to carry and store.

[0028] Long tube clamping and fixing:

[0029] The support platform 1 has a recessed groove 2 at its center to hold long pipes. The support platform 1 has an outer clamping block 9 and an inner clamping block 13 on its side, which are connected by a connecting rod 10. The outer clamping block 9 is located outside the support platform 1 and extends out from the groove 2, while the inner clamping block 13 is located inside the support platform 1. The two are distributed at intervals.

[0030] A drive box 8 is installed at the bottom of the support platform 1. An adjusting screw 7 is rotatably installed inside the drive box 8, and the threads on the outer wall of the adjusting screw 7 are reversed. A moving block 14 protrudes from the bottom of the inner clamping block 13 and is threadedly connected to the adjusting screw 7. When it is necessary to clamp a long pipe, the adjusting screw 7 is rotated. Because the threads on the outer wall of the adjusting screw 7 are reversed, the two inner clamping blocks 13 will move in opposite directions along the adjusting screw 7, which in turn drives the outer clamping block 9 to move through the connecting rod 10. When the outer clamping block 9 approaches the long pipe in the pipe groove 2, it clamps the uncut or cut long pipe separately to ensure that the long pipe remains stable during the cutting process and does not shake or shift.

[0031] Installation and adjustment of cutting saw blade 17:

[0032] The upper surface of the support platform 1 is provided with mounting holes 11, and the side wall of the support platform 1 is provided with threaded holes. The threaded holes and mounting holes 11 are vertically distributed and communicate with each other. A fixing post 15 is vertically installed in the mounting hole 11. A limit hole is provided on the side wall of the fixing post 15, and a limit bolt 4 is installed in the threaded hole. By inserting the limit bolt 4 into the limit hole, the fixing post 15 can be fixed on the support platform 1.

[0033] A lifting rod 5 slides vertically inside the fixed column 15, and a handle 6 is fixedly connected to the end of the lifting rod 5 away from the fixed column 15. A limit rod 16 passes through the outer wall of the fixed column 15, and the lifting rod 5 has a hole for fitting the limit rod 16. When it is necessary to adjust the height of the cutting saw blade 17, the limit rod 16 is first pulled out, and then the lifting rod 5 is moved up and down by the handle 6. A fixed frame 19 is welded to the lifting rod 5, and the saw blade 17 and a motor are installed on the fixed frame 19. The motor drives the saw blade 17 to rotate, thereby cutting the long pipe. A lifting groove 18 is vertically opened on the fixed column 15, and the fixed frame slides through the lifting groove 18 to ensure that the fixed frame 19 can move stably during the lifting of the lifting rod 5, thereby ensuring the accuracy of the cutting of the saw blade 17. As the lifting rod 5 descends, the long pipe is cut. After completion, the lifting rod 5 is pulled up, and then the limit rod 16 is inserted.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
