Laser tube cutting machine is a high-precision equipment that utilizes laser technology for tube cutting. It is widely used in the metal processing industry due to its characteristics of fast, accurate, and efficient.

 

The working principle of laser tube cutting machine is to use laser beam to cut the tube. The laser beam is focused by the optical system to form a high-energy density spot, and then the spot is moved through the control system to realize the cutting of the tube. Laser tube cutting machine can adjust the focal length and power of the laser beam according to different tube diameters and cutting requirements to achieve the best cutting effect.

The composition of laser tube cutting equipment is relatively complex, generally including laser generator, manipulation and drive system software, three-dimensional mechanical hand laser cutting machine tool, optical fiber guide outer loop system software, laser cutting head, operating table, etc., as well as pneumatic rotating tooling, rotating tooling, fully automatic left and right feed equipment, refrigeration unit, frozen dryer, adjustable voltage regulator power supply and other components.

The application scope of laser tube cutting machine is wide, it can exert high-precision advantages in various metal tube cuts. Compared with traditional production and processing methods, laser tube cutting machine can perform laser drilling, seam cutting, and contour laser cutting on the surface of the tube, which has the characteristics of high precision and makes each component have the same specification.

It should be noted that laser tube cutting machine requires professional guidance and attention during operation, including using high-pressure water or air to blow away the molten pool and other steps. In practical applications, it also needs to make corresponding adjustments and optimizations according to different factors such as tube material and thickness.

Pipe fixation: Before the cutting process begins, the pipe that needs to be cut needs to be fixed onto a cutting platform. This task is usually accomplished manually by the operator. To ensure the stability of the pipe during the cutting process, the platform commonly adopts either vacuum adsorption or mechanical clamping to fix the pipe in its designated position. At the same time, the operator must also ensure that the position and angle of the pipe are accurate, for ease of subsequent cutting operations.

Laser emission: Laser pipe cutting machines are equipped with high-energy lasers that can focus the laser beam onto the pipe. The power and shape of the laser beam can be adjusted according to different cutting requirements. During the cutting process, the laser beam is emitted through the laser and passes through a series of optical elements and reflectors, finally focusing onto the surface of the pipe.
Beam guidance

Laser pipe cutting machines usually possess a guidance system that can accurately guide the laser beam to the desired cutting position. This process is completed by a computer control system. The guidance system includes a series of reflectors and optical elements that can change the direction and shape of the laser beam to adapt to different diameters and shapes of pipes. At the same time, the control system can also achieve functions such as automatic alignment and automatic tracking to ensure that the laser beam accurately irradiates the target position without error.

Focus adjustment: During the laser cutting process, it is necessary to focus the laser beam onto the surface of the pipe. This process is completed by a focus adjustment mechanism. The focus adjustment mechanism usually includes a series of reflectors and lenses used to adjust the focal length and position of the laser beam. During the process of adjusting the focus, the operator needs to observe the clarity of the cutting position and the quality of the cutting seam through a monitor, and continuously adjust the focal length and position of the laser beam until the best cutting effect is obtained.

Once the focus is adjusted, the laser pipe cutting machine can begin the cutting process. During this process, the laser beam travels along the pipe at a certain speed to achieve pipe cutting. During the cutting process, operators need to closely monitor cutting quality and speed, and adjust the power and speed of the laser beam according to different materials and thickness. If any problems occur during the cutting process, such as poor quality of the cutting seam or insufficient melting of the material, operators need to adjust the parameters of the laser beam in real time or pause cutting for inspection and maintenance.

Waste slag removal: During the cutting process, waste slag such as oxide slag and molten slag will be generated. If these wastes are not removed, they may affect the cutting quality and normal operation of the equipment. Therefore, laser pipe cutting machines are usually equipped with waste slag removal systems. This system is composed of scrapers, vacuums, etc., which can promptly remove waste slag around the cutting seam. At the same time, these wastes can also be collected through vacuums for subsequent processing and reuse.

Cooling: Laser pipe cutting machines are usually equipped with cooling systems to prevent excessive heat from affecting equipment components. This system usually uses low-temperature liquid (such as water) to pass through a heat exchanger in the equipment and remove heat from equipment components. At the same time, cooling systems can also cool optical elements to prevent excessive heat from having adverse effects on their performance.
