Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting, in particular to a high-precision adjustable pipe cutting machine. Background Art

[0002] A high precision adjustable pipe cutter is a device used to cut pipes, tubes or tubes. Its main feature is that it can cut with high precision and in an adjustable manner. This type of machine is commonly used in a wide range of fields such as metal processing, construction, manufacturing and pipeline engineering.

[0003] When using it, first adjust the parameters of the pipe cutter (such as cutting angle) according to the required cutting size and pipe specifications, then measure the length of the pipe to be cut and mark the place to be cut, then place the pipe to be cut into the working area of ​​the pipe cutter, ensuring that the pipe is fixed and in the correct position. Finally, start the pipe cutter according to the instructions in the operating manual or on the machine, and let the pipe cutter cut automatically.

[0004] However, it is difficult to control the clamping force when clamping the pipe on the existing cutting machine. If the clamping force is too small, the pipe may be displaced during cutting, resulting in cutting failure. At the same time, some pipes have thin walls, and if the clamping force is too large, the thin pipes may be deformed, causing inconvenience in the subsequent use of the pipes. Measuring the length of the pipe and marking it before each cutting also affects the cutting efficiency of the pipe to a certain extent. To this end, we propose a high-precision adjustable pipe cutting machine. Utility Model Content

[0033] Similarly, when it is necessary to cut a square tube, the square tube only needs to be placed between the four square plates 8 and the handle 15 can be turned to clamp and fix the square tube. It has good applicability and is easy to operate. At the same time, the clamping and fixing force of the square tube or round tube of the tube cutting machine is easy to control to achieve the clamping effect, and it also avoids deformation of the tube due to excessive clamping force.

[0034] Example 2: Please refer to Figure 1 and Figure 2 The present embodiment further explains the first embodiment.

[0037] In this embodiment, when it is necessary to adjust the cutting length of the pipe, the knob screw 11 is first turned outward before fixing the pipe. The knob screw 11 will rotate forward in the inner wall of the square frame 10, and the knob screw 11 will leave the concave plate 6. Then the push plate 12 can be moved, and the push plate 12 will drive the square frame 10 to slide on the concave plate 6. The square frame 10 will drive the positioning plate 5 to slide on the cutting table 1 until the positioning plate 5 moves to the required position (refer to the scale line 14 on the concave plate 6). Then the knob screw 11 is tightened in the inner wall of the square frame 10 again, and the knob screw 11 is tightly fitted with the concave plate 6. Then the positioning plate 5 can remain fixed after moving, and the operation is simple.

[0038] It should be noted that the clamping force of the cutting machine when fixing the pipe is easy to control, which not only avoids the displacement of the pipe during cutting due to insufficient clamping force, but also avoids the deformation of thin-walled pipes due to excessive clamping force. There is no need for workers to measure and mark the pipe length before each cutting, which is conducive to improving the cutting efficiency of the pipe.
