[0038] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0039] With reference to FIG. 1, FIG. 2 and FIG. 5, one embodiment provided by the utility model is a heavy pipe side-hung three-dimensional laser pipe cutting machine, which comprises a shell 1 and a rack 2. The inner top of the shell 1 is fixedly connected with a laser cutting head 5. The inner top of the shell 1 is fixedly connected with a blowing mechanism. The outer side of the rack 2 is fixedly connected with a buffer mechanism.

[0040] With reference to FIG. 1 to FIG. 3, the blowing mechanism comprises a shell 1. The shell 1 is wrapped on the outer side of the pipe cutting machine as a whole, which plays a role of protection, beauty and isolation of internal working components and external environment. The material of the shell 1 is usually selected from steel plate or aluminum alloy plate, etc. The shell 1 has sufficient strength, which can resist external force collision and environmental erosion to a certain extent. The inside of the shell 1 can be fixed with subsequent components and related lines, thereby improving the stability of the device. The inner top of the shell 1 is fixedly connected with a motor 1 6. The motor 1 6 is one of the power sources in the blowing mechanism, which has appropriate power and can provide stable rotating power for subsequent components connected therewith, so that the whole blowing device can rotate around its axis to blow the cutting area at multiple angles.

[0041] The blowing operation can cover different cutting points in different directions through the driving of the motor 1 6, effectively remove the debris and other sundries generated during cutting, and quickly cool down to reduce the thermal deformation of the pipe.

[0042] A support assembly is fixedly connected to the top inner side of the outer casing 1. A rotating ring 9 is fixedly connected to the top of the shaft of motor 6. The rotating ring 9 is used to support and carry subsequent components. The bottom of the rotating ring 9 has a limit structure to prevent motor 6 from being driven and damaged when subsequent components extend or retract. A support arm 10 is rotatably connected to the inner side of the rotating ring 9. The support arm 10 serves as a connection and support. It is made of high-strength metal material to prevent the connected object from falling and being damaged due to vibration during operation. A bent rod 11 is fixedly connected to one end of the support arm 10. The bent rod 11 is used for subsequent angle adjustment and serves as a connection and support when subsequent components are raised or lowered. A spherical slider 12 is fixedly connected to one end of the bent rod 11. Its main function is to cooperate with subsequent components to allow the entire air blowing part to be flexibly adjusted within a certain range when the extension and retraction components move, further optimizing the air blowing angle and position, so that the high-pressure nozzle 15 can more accurately clean up debris generated by pipe cutting and enhance the air blowing effect.

[0043] A grooved ring 13 is slidably connected to the outer side of the spherical slider 12. The grooved ring 13 ensures that the spherical slider 12 slides freely within the groove, while preventing it from coming off or becoming unstable. This limits the rotation range of the spherical slider 12, making the device more stable. A telescopic component is fixedly connected to the bottom of the grooved ring 13, and an air pump 14 is fixedly connected to the top of the support arm 10. The air pump 14 is a key device for generating high-pressure gas. Through the coordinated operation of its internal components, the air pump 14 draws in and compresses outside air, then outputs high-pressure gas. The pressure and flow rate of the output gas can be adjusted according to different pipe types to enhance the air blowing cleaning effect. A high-pressure nozzle 15 is fixedly connected to the outer side of the air pump 14. The high-pressure nozzle 15 has a special internal structure.

[0044] The flow channel shape can effectively converge and accelerate the high-pressure gas output by the air pump 14, so that the gas is ejected at high speed and in a concentrated state, thereby generating a powerful impact force. This force can quickly blow away debris, slag and other impurities generated during pipe cutting from the cutting area, and can also quickly cool the cutting area to avoid local overheating and deformation, thus protecting the performance of the pipe material.

[0045] The support assembly includes a support frame 7, which connects the housing 1 and subsequent components, providing mechanical support and ensuring the stability of the internal structure of the device during operation. A fixing block 8 is fixedly connected to the top of the support frame 7. The fixing block 8 protects the shaft of motor 6 and limits the movement distance and range of subsequent components, preventing damage caused by collisions between components during device operation. The outer side of the shaft of motor 6 is rotatably connected to the inner side of the fixing block 8.

[0046] The telescopic assembly comprises a cylinder 16, which is the core power component of the telescopic assembly and drives the push rod 17 inside to perform telescopic movement through pressure change of the gas.

The bottom of the buffer rod 22 is fixedly connected with a supporting rod 21. The supporting rod 21 is made of smooth and high-strength metal rod, such as round steel, and has an outer diameter slightly smaller than the inner diameter of the spring 20, so that the spring 20 can be closely sleeved on the outside of the supporting rod 21, and can smoothly slide relative to the spring 20 when the spring 20 expands and contracts, preventing the spring 20 from being tilted when compressed and causing damage to the pipe.

[0052] The inner side of the spring 20 is sleeved on the outside of the supporting rod 21. The top end of the buffer rod 22 is rotatably connected with a rotating shaft 23. The rotating shaft 23 serves as a rotating connection and is made of high-precision metal shaft.

The shape of the conveying roller 27 is a sandglass shape, and the surface is treated for anti-skid and wear-resistant, and is wrapped with a rubber layer to increase the friction between the pipe and the conveying roller 27, preventing the pipe from slipping during conveying. The diameter, length and material of the conveying roller 27 are reasonably selected according to the pipe specifications, weight and other factors to ensure stable and efficient pipe conveying and smooth material flow of the whole pipe cutting machine. The outer side of one end of the conveying roller 27 is fixedly connected to the output end of the motor 26.

[0056] The outer side of the shell 1 is provided with a groove, and the groove of the shell 1 is fixedly connected with a viewing window 30, which is convenient for real-time observation of the cutting process and observation of the position and fixing condition of the pipe, so that the staff can timely find safety hazards and prevent accidents.
