Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipe cutting, and particularly relates to a pipe cutting device with adjustable angle. Background Art
[0002] Pipes are the most basic conveying tools in industrial production. During the pipe installation process, pipes need to be cut and welded. However, sometimes it is necessary to cut the pipes at an angle to adapt to different installation environments. The most commonly used cut is at a 45° angle, but sometimes cuts at other angles may occur due to various reasons. The current cutting method is to manually observe and estimate the angle to be cut, then cut, and repeatedly compare and correct it before welding. This method has a large deviation. After multiple corrections, the cut is uneven, and the gap is large after docking, making it not easy to weld, seriously affecting the welding quality of the pipe and prone to leakage points during use. Summary of the Invention
[0003] The purpose of the utility model is to provide a pipe cutting device with adjustable angle to solve the problems existing in the prior art.
[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0005] A pipe cutting device with adjustable angle includes a square pipe, on which a ruler box and several fixed pipe nuts are welded. A fixed pipe bolt is threadedly connected inside the fixed pipe nut, and the tail of the fixed pipe bolt penetrates through the square pipe. A fixed angle rod is hinged to the square pipe. A fixed angle ruler is inserted into the ruler box. The fixed angle rod is bolted to the fixed angle ruler through a bolt pair. The fixed angle ruler is provided with scales. A fixed ruler nut is welded on the ruler box, and a fixed ruler bolt is threadedly connected inside the fixed ruler nut, and the tail of the fixed ruler bolt penetrates through the ruler box.
[0006] Further, the square pipe is a square tubular structure with a hollow interior and both ends open. The hinge point of the fixed angle rod and the square pipe is located at a corner on the upper top surface of the square pipe. The angle at the hinge point of the fixed angle rod and the square pipe is the hinge angle of the square pipe, and the vertical side of the hinge angle is a rounded edge.
[0007] Further, there are two fixed pipe nuts, and the two fixed pipe nuts are linearly distributed on the central axis of the upper top surface of the square pipe.
[0008] Further, the ruler box is a square tubular structure with a hollow interior and both ends open. The ruler box is located on the side of the upper top surface of the square pipe opposite to the hinge angle, and the ruler box and the hinge angle are at the same open end of the square pipe.
[0009] Further, a strip hole is formed on the fixed angle rod.
[0010] Further, the fixed angle ruler is a cuboid structure and matches the inner cavity of the ruler box. One end of the fixed angle ruler is arc-shaped, and the bolt pair penetrates through the arc-shaped end of the fixed angle ruler and the strip hole to bolt the fixed angle ruler and the fixed angle rod.
[0011] Further, two clamping plates are symmetrically welded on the inner wall of the bottom of the square pipe.
[0012] The utility model has the following beneficial effects:
[0013] 1. The utility model can adjust the cutting angle of the pipeline, thereby improving the accuracy of the pipeline cutting angle, preventing multiple corrections and too large gaps caused by excessive errors, thereby improving the welding quality, and further avoiding leakage points in the pipeline.
[0014] 2. The cutting angle of the pipeline is assisted by the fixed-angle rod. When cutting, it only needs to cut vertically downward along the official of the fixed-angle rod, and the operation is convenient.
[0015] 3. The angle of the fixed-angle rod is determined by the fixed-angle ruler, and the operation is convenient and the accuracy is high, thereby improving the accuracy of the cutting angle of the pipeline.
[0016] 4. When cutting a pipeline with a smaller diameter, since the pipeline is placed between two clamping plates, the pipeline will not slide to both sides, so it is convenient to fix the pipeline and adapt to the cutting of pipelines with different diameters.
[0017] 5. The vertical side of the hinged angle is a rounded edge. When the fixed-angle rod rotates to a certain angle, if this side is a right angle, it will protrude from the fixed-angle rod, which has an obstructive effect on cutting. That is to say, this side will be cut during cutting. After being designed as a rounded edge, no matter how the fixed-angle rod rotates, the rounded edge will not protrude, so as not to hinder the cutting of the pipeline.
[0018] 6. One end of the fixed-angle ruler hinged to the fixed-angle rod is designed as an arc shape to make a cutting space. No matter how the fixed-angle rod rotates, the fixed-angle ruler will not protrude from the fixed-angle rod, so as not to hinder the cutting of the pipeline. Description of the Drawings

[0022] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the following further details the present utility model in conjunction with specific embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0023] As Figure 1 shown, an adjustable-angle pipe cutting device includes a square pipe 1, on which a ruler box 2 and several fixed pipe nuts 3 are welded. A fixed pipe bolt 4 is threadedly connected inside the fixed pipe nut 3, and the tail of the fixed pipe bolt 4 penetrates through the square pipe 1. A fixed angle rod 5 is hinged on the square pipe 1. A fixed angle ruler 6 is inserted into the ruler box 2. The fixed angle rod 5 is bolted to the fixed angle ruler 6 through a bolt pair 7. A scale 8 is provided on the fixed angle ruler 6. A fixed ruler nut 9 is welded on the ruler box 2, and a fixed ruler bolt 10 is threadedly connected inside the fixed ruler nut 9. The tail of the fixed ruler bolt 10 penetrates through the ruler box 2. When marking the scale 8, tools such as a protractor can be used for assistance. Rotate the fixed angle rod 5 to different angles and mark on the fixed angle ruler 6 close to the edge of the ruler box 2.
[0024] The square pipe 1 is a square tubular structure with a hollow interior and open ends at both ends. The hinge point of the fixed angle rod 5 and the square pipe 1 is located at a corner on the upper top surface of the square pipe 1. The angle at the hinge point of the fixed angle rod 5 and the square pipe 1 is the hinge angle of the square pipe 1, and the vertical side of the hinge angle is a rounded edge. The purpose of the rounded edge is that when the fixed angle rod 5 rotates to a certain angle, if this side is a right angle, it will protrude from the fixed angle rod 5, which has an obstructive effect on cutting. That is to say, it will be cut during cutting. After designing it as a rounded edge, no matter how the fixed angle rod 5 rotates, the rounded edge will not protrude, thus not interfering with the cutting of the pipe.
[0025] There are two fixed pipe nuts 3, and the two fixed pipe nuts 3 are linearly distributed on the central axis of the upper top surface of the square pipe 1. The fixed pipe nut 3 is used to press the pipe inside the square pipe 1.
[0026] The ruler box 2 is a square tubular structure with a hollow interior and open ends at both ends. The ruler box 2 is located on the side of the upper top surface of the square pipe 1 opposite to the hinge angle, and the ruler box 2 and the hinge angle are at the same open end of the square pipe 1. Since the fixed angle rod 5 and the fixed angle ruler 6 are bolted together, the fixed angle ruler 6 is also drawn out of the ruler box 2 following the rotation of the fixed angle rod 5, and the scale 8 value close to the edge of the ruler box 2 is checked to determine the angle value of the fixed angle rod 5.
[0027] The fixed angle ruler 6 is a cuboid structure and matches the inner cavity of the ruler box 2. One end of the fixed angle ruler 6 is arc-shaped. The bolt pair 7 penetrates through the arc-shaped end of the fixed angle ruler 6 and the strip hole 11 to bolt the fixed angle ruler 6 and the fixed angle rod 5. The end of the fixed angle ruler 6 hinged to the fixed angle rod 5 is designed to be arc-shaped also to make room for cutting. Otherwise, when the fixed angle rod 5 rotates to a certain angle, the fixed angle ruler 6 will protrude from the fixed angle rod 5, which has an obstructive effect on cutting. That is to say, it will be cut during cutting.
[0028] On the inner wall at the bottom of the square pipe 1, two clamping plates 12 are symmetrically welded. When cutting a pipe with a smaller diameter, since the pipe is placed between the two clamping plates 12, the pipe will not slide to both sides, thus facilitating the fixation of the pipe and adapting to the cutting of pipes with different diameters.
[0029] The working principle of the present utility model is as follows:
[0030] As Figure 2 shown, when in use, the pipe 13 to be cut is inserted into the square pipe 1, and the bottom end of the pipe 13 to be cut is located between the two clamping plates 12. One end of the pipe 13 to be cut protrudes. Tighten the fixed pipe bolt 4, so that the bolt tail of the fixed pipe bolt 4 tightly abuts against the pipe 13 to be cut, thereby fixing the pipe 13 to be cut in the square pipe 1.
[0031] After fixing the pipe 13 to be cut, loosen the bolt pair 7, but do not disassemble it. At this time, rotate the fixed angle rod 5. Since the fixed angle rod 5 is bolted to the fixed angle ruler 6 and the bolt pair 7 slides in the strip hole 11, the fixed angle ruler 6 also follows the rotation of the fixed angle rod 5 and is drawn out from the ruler box 2. The extended length of the fixed angle ruler 6 determines the angle of the fixed angle rod 5. Check the scale 8 value close to the edge of the ruler box 2 to determine the angle value of the fixed angle rod 5.
[0032] After rotating the fixed angle rod 5 to an appropriate angle, tighten the fixed ruler bolt 10 and the bolt pair 7. The fixed angle ruler 6 is fixed in the ruler box 2, and the fixed angle rod 5 is also fixed on the fixed angle ruler 6 and the square pipe 1, thereby fixing the rotation angle of the fixed angle rod 5. Then, cut the pipe 13 to be cut vertically downward along the outer edge of the fixed angle rod 5.
[0033] When marking the scale 8, tools such as a protractor can be used for assistance. Rotate the fixed angle rod 5 to different angles and mark on the fixed angle ruler 6 close to the edge of the ruler box 2.
[0034] When cutting a pipe with a smaller diameter, since the pipe is placed between the two clamping plates 12, the pipe will not slide to both sides, thus facilitating the fixation of the pipe and adapting to the cutting of pipes with different diameters.
[0035] The above-described embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model should all fall within the protection scope of the present utility model.
