[0002] Steel pipes are not only used to transport fluids and powdered solids, exchange heat, and manufacture mechanical parts and containers, but they are also an economical steel material. Using steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of ​​protective coating, saving investment and maintenance costs. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight and realize factory-based mechanized construction, so the application of steel pipes is becoming more and more extensive. Steel pipe cutting machines are commonly used equipment in the field of machinery, and are widely used in various industries and pipeline installation projects, pipeline maintenance, etc. in new projects.

[0003] However, many steel pipe cutting machines currently have complex structures, large volumes, and high costs, and are poorly suitable for cutting steel pipes of different diameters. In addition, most steel pipe cutting machines use cutting saws or blades to cut steel pipes, which produce loud processing noise, are prone to spark splashing, and have poor safety. They have an impact on the environment and the physical and mental health of processing personnel. In addition, when cutting the same steel pipe multiple times, the steel pipe needs to be moved manually, which increases labor intensity and reduces processing efficiency.

[0004] Therefore, in view of the above problems, a semi-automatic steel pipe cutting machine is proposed to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-4 As shown, the utility model provides a technical solution:

[0027] A semi-automatic steel pipe cutting machine includes a base frame 1 and a rolling assembly 2, the rolling assembly 2 is arranged on the base frame 1, the rolling assembly 2 includes rollers 21, the rollers 21 include at least two rollers, two rollers 21 form a group, the axes of the rollers 21 are arranged parallel to each other, the two ends of the rollers 21 are arranged on the base frame 1 through a moving assembly 3, and the moving assembly 3 is used to change the distance between the rollers 21; the cutting assembly 4 includes a crossbeam 41, which is arranged on the base frame 1 on one side of the rolling assembly 2, and the length direction of the crossbeam 41 is parallel to the axis direction of the roller 21.

[0028] In this embodiment, the moving assembly 3 includes a rack 31, a gear 32, a power piece 33 and a moving seat 34. The moving seat 34 is slidably arranged on the base frame 1, and the power piece 33 is arranged on the moving seat 34. The output end of the power piece 33 is connected to the gear 32 and can drive the gear 32 to rotate. The gear 32 is meshed with the rack 31. The rack 31 is arranged on the base frame 1, and the length direction of the rack 31 is perpendicular to the axial direction of the roller 21. The power piece 33 is started to drive the gear 32 to rotate. Since the gear 32 is meshed with the rack 31, the gear 32 drives the moving seat 34 to move, thereby adjusting the distance between the rollers 21 to adapt to the cutting of steel pipes with different diameters, thereby improving the practicability of the device.

[0029] In this embodiment, the rolling assembly 2 also includes a power piece 22, which is arranged on a moving seat 34 of the moving assembly 3. The output end of the power piece 22 is coaxially connected to one end of the roller 21 to drive the roller 21 to rotate. Both ends of the roller 21 can be connected to the power piece 22, or one end can be connected to the power piece 22 and the other end can be movably arranged on the moving seat 34, which is more economical. The rotation direction of the roller 21 is consistent, so that it can drive the steel pipe to rotate, which is convenient for radial cutting of the steel pipe and improves processing efficiency.

[0030] In another embodiment, the outer surface of the roller 21 is evenly provided with a rough surface to increase the friction between the roller 21 and the steel pipe, thereby preventing the steel pipe from sliding and causing unsatisfactory cutting effects, thereby improving the processing quality of the device.

[0031] In this embodiment, the cutting assembly 4 also includes a clamping frame 42 and a cutting gun 43. The clamping frame 42 is slidably set on the beam 41 and can move along the length direction of the beam 41. The cutting gun 43 is set on the clamping frame 42, and the muzzle of the cutting gun 43 faces the rolling assembly 2. According to the position where the steel pipe is required to be cut, the clamping frame 42 is slid until the muzzle of the cutting gun 43 is aimed at the steel pipe. The cutting gun 43 can use an oxygen-acetylene cutting gun. An oxygen supply pipe and an air supply pipe are set at the tail of the gun. The oxygen and acetylene in the oxygen supply pipe and the air supply pipe are mixed, and flames are burned at the muzzle. The steel pipe is cut by a high-temperature flame, instead of cutting with traditional saw blades, etc., to avoid the generation of a large number of sparks during the cutting process, which may have adverse effects on the environment and workers, thereby improving the safety of the device.

[0032] In this embodiment, the connecting rod between the crossbeam 41 and the base frame 1 is configured as a telescopic adjustment rod to adjust the height of the cutting gun 43, which is more suitable for cutting steel pipes of different diameters and heights, thereby improving the practicability of the device.

[0033] In this embodiment, a slide groove is set on the contact surface of the movable seat 34 with the base frame 1, and a sliding ridge is set on the base frame 1 at a position opposite to the slide groove, and the length direction of the sliding ridge is parallel to the rack 31. The slide groove and the sliding ridge are slidably connected to prevent the movable seat 34 from falling off the base frame 1 when moving, thereby improving the stability of the device.

[0034] In another embodiment, a threaded hole is opened on the slide groove, and a plurality of threaded holes corresponding to the threaded holes on the slide groove are opened on the slide ridge along its length direction, and the slide groove and the slide ridge can be connected by bolts, so that the position of the movable seat 34 can be fixed by bolts after the slide groove moves into place along the slide ridge, thereby preventing the steel pipe from falling due to the change of position of the movable seat 34 due to gravity when the steel pipe is cut, thereby improving the safety and stability of the device during use.

[0035] In another embodiment, a plurality of groups of rollers 21 are arranged on the base frame 1, and a moving assembly 3 and a cutting assembly 4 are arranged corresponding to each group of rollers 21, so that a plurality of steel pipes can be cut at the same time, thereby improving the processing efficiency of the device.

[0036] Working principle: First, adjust the distance between the rollers 21 according to the diameter of the steel pipe to be cut. Specifically, start the power piece 2 33 at the end of each roller 21, the power piece 2 33 drives the gear 32 to rotate, the gear 32 is meshed with the rack 31, and the gear 32 drives the moving seat 34 to move, so that the distance between the two rollers 21 is smaller than the diameter of the steel pipe to be cut; place the steel pipe between the two rollers 21, and the axis of the steel pipe is parallel to the axis of the two rollers 21; adjust the height of the beam 41 by the telescopic adjustment rod, so that the nozzle of the cutting gun 43 is close to the outer wall of the steel pipe; move the position of the cutting gun 43 on the beam 41 according to the need for the cutting position of the steel pipe; start the power piece 1 22 to rotate the roller 21, thereby driving the steel pipe to rotate; then turn on the switch of the cutting gun 43, use the flame to cut the steel pipe, and cut the steel pipe while it rotates, so that the cutting is more stable, the quality is better, and the practicality is improved.
