Research on Laser Cutting of Pipe

 The laser has three characteristics of good monochromaticity, coherence, and parallelism, so it is particularly suitable for material processing. The traditional domestic pipe cutting methods mainly rely on manual sawing, sawing machine sawing, roller extrusion, grinding wheel cutting, gas welding cutting, etc. These processing methods basically have the disadvantages of low cutting efficiency and high labor intensity of workers, while laser cutting is faster The processing efficiency, good processing effect, and other advantages are widely used in the industrial field.

With the development of science and technology and industry, pipes have been widely used to manufacture parts in aircraft manufacturing, engineering machinery, transportation, petrochemical, agricultural and animal husbandry machinery, and other industrial sectors. In actual production, the pipe has the advantages of low production cost, good processability, lightweight of structural parts, and material saving. Therefore, pipe cutting has a very important position in the industrial field. Due to the different shape, size, and application of the pipe, and the cutting of the pipe is restricted by factors such as processing quality, it is very important to choose reasonable processing equipment, processing methods, and technological measures.

There are many inconveniences in tube cutting, and although domestic traditional cutting methods can also achieve application results, but the processing efficiency is low and the processing effect is poor, so combining tube cutting with laser technology will make the field of tube cutting have a broader development prospect.

Current status and future development of tube laser cutting

Tube laser cutting has many advantages such as narrow cut width, small heat-affected zone, fast cutting speed, good flexibility, clean-cut, and no tool wear. With the emergence and development of CNC laser pipe cutting machines, the development of various processing techniques for spatial freeform surfaces and curves can show its unique side. When laser cutting a pipe, not only does the laser spot move in a certain trajectory relative to the workpiece in three-dimensional space but also requires that during the entire processing process, the laser optical axis is always perpendicular to the processing surface of the pipe to be cut. For a CNC fiber laser cutting head that can perform automatic focusing, its nozzle can automatically track the surface of the workpiece through an automatic measurement and control system. Production practice shows that the key to pipe cutting is to eliminate the cutting quality defects to the greatest extent, so as to meet the processing requirements of the pipe. For the processing of complex pipes, such as perforation, grooving, trimming, or undercutting, laser cutting is not only faster than traditional processing methods but also can greatly guarantee the processing quality.

Overview of pipe laser cutting machine

In the process of processing, first of all, the pipe parts should be cut to obtain the required length of the pipe blank. The traditional domestic pipe cutting methods are difficult to meet the needs of mass production, and the pipe parts processed by these traditional processing methods are generally of poor quality in the cut surface, and some even have processing defects such as deformation and collapse. In addition to cutting pipes, some also require other forms of processing, such as: cutting patterns for decoration and lamps, spiral, sine, cosine cutting, marking, etc. If the traditional processing methods are used for these forms of tube processing, not only the processing efficiency is low, but also it is difficult to meet the ideal processing requirements, and some of them cannot even be processed.

Advantages of tube laser cutting

Using laser to cut pipes (including tangent, oblique cutting, forming cutting, etc.), the width of the cut is generally 0.1-0.3mm, and the cutting position and temperature can be accurately controlled, which is more conducive to the realization of automation and intelligence in production, and the cutting efficiency is relatively high. The traditional processing method can be increased by 8-20 times, the processing cost can be reduced by 70%-90%, and the material loss can be saved by 15%-30%, and the noise of laser cutting is small and the environmental impact is small. Traditional processing methods require multiple continuous processes to complete the processed parts that can be achieved by laser cutting on the same equipment. With the continuous improvement of equipment performance and continuous improvement of processing technology, it is possible to use a laser to perform the high-quality cutting of pipes.

The future development trend of pipe laser cutting machine

Laser cutting uses a non-contact processing method. During the entire processing process, there will be no pressure on the pipe wall, so it will not cause the outer surface of the pipe to deform or collapse. At the same time, when laser cutting pipes, the complexity of the kerf thermal field, difficulty in cooling, and easy blockage of cutting slag make cutting more difficult. Therefore, in-depth research on these aspects should be strengthened.

Laser cutting requires a lot of freedom on the material, shape, size, processing environment, etc. of the tube, and its spatial controllability (change in the direction of the beam, rotation, scanning, etc.) and time controllability (open, close, pulse interval) Excellent, easy to control, and because the laser cutting has high precision and few burrs, it greatly reduces the time consumed for subsequent processing. When changing the diameter or shape of the pipe, you only need to modify the program, so the development of pipe cutting software is of great research value. The combination of laser cutting systems and computer numerical control technology can form efficient automation equipment, opening up a new path for high-quality, efficient, and low-cost processing.

In order to improve the efficiency of tube laser cutting, the most effective production method is to use the automatic tube laser cutting production line. How to use automatic tube cutting production line for laser cutting? Firstly, the focused laser beam must be synchronized with the pipe being cut on the automatic pipe cutting production line; secondly, the focused laser beam must be able to rotate one circle relative to the pipe being cut, and the laser beam axis must always be perpendicular to the pipe axis. Intersect, in the cutting process, the laser beam of the pipe cutting production line moves with the pipe being cut. These synchronous movements must be controlled by a special control system, so the research on the automatic tube laser cutting production line is also of great significance.

Technological Revolution of Sheet Metal Processing -- Fiber Laser Cutting Machine!

 The sheet metal industry is one of the most important application markets for laser processing. China's huge potential market also provides a broad space for the application of laser equipment in the sheet metal industry. As the competition intensifies, the competition in the sheet metal market will turn into a competition for high-quality, high-tech products.

Therefore, in order to adapt to the development trend of the international market, the transformation of processing technology is inevitable. As a new technology, laser processing technology is the product of modern scientific development. Laser cutting, laser welding, laser marking, and other technologies are increasingly used in the sheet metal processing industry.


What is sheet metal? So far, sheet metal has not yet had a relatively complete definition.


1. According to the analysis in a foreign professional journal, it can be defined as sheet metal is a comprehensive process for metal sheets (usually below 6mm), including shearing, punching/cutting/compositing, folding, welding, riveting, splicing, Forming (such as car body), the obvious feature is the same thickness of the same part.

2. Explanation of "Modern Chinese Dictionary (5th Edition)"-Sheet Metal: Verb, processing metal plates such as steel plates, aluminum plates, copper plates, etc.

Sheet Metal and Fiber Laser Metal Cutting Machine

China has gradually become an international processing and manufacturing center. As the demand for metal processing continues to increase, the electrical control boxes and machine casings in the metal processing industry are generally sheet metal parts, so the demand for sheet metal processing capabilities is also increasing; As a result, the complexity of the process is relatively high, and even some parts have reached dozens of procedures, which puts forward higher requirements for sheet metal processing in terms of accuracy.

Sheet Metal Fiber Laser Cutting Machine is progress on the shoulders of giants. It first started to rise in foreign developed countries, driving the rapid development of its related manufacturing industries. China has started to catch up in recent years, and it has already achieved success in the field of fiber laser cutting machines. This achievement has enabled China to shorten the gap between high-end manufacturing and foreign high-end equipment manufacturing. It may even allow China's high-end equipment manufacturing to catch up with the pace of foreign high-end equipment manufacturing technology. Fiber laser cutting machines help China's manufacturing industry achieve leapfrog development.


Disadvantages of Traditional Sheet Metal Processing


Traditional sheet metal processing technology: shearing-punching-bending-welding process or flame plasma cutting-bending-welding process. In the face of orders of multiple varieties, small batches, customization, high quality, and short delivery time, it has obvious shortcomings:

1. (Numerical control) Shearing machine is mainly used for straight-line cutting, it can only be used for sheet metal processing which only needs straight line cutting;

2. (CNC/Brick Tower) The punch press has restrictions on the cutting of steel plates with a thickness of more than 1.5mm, and the surface quality is not good, the cost is high, the noise is large, and it is not conducive to environmental protection;

3. Flame cutting is the original traditional cutting method. When cutting, the thermal deformation is large, the slit is wide, the material is wasted, the processing speed is slow, only suitable for rough processing;

4. The high-speed water cutting process is slow, causing serious pollution and high consumption cost.



Advantages of Sheet Metal Fiber Laser Cutting Machine China


In response to the problems of traditional sheet metal cutting at this stage, the demand for laser cutting is also increasing.

1. Laser cutting has a high degree of flexibility, fast cutting speed, high production efficiency, and short product production cycle. Whether it is simple or complex parts, you can use a laser to achieve rapid prototyping and cutting;

2. Narrow cutting seam, good cutting quality, a high degree of automation, easy operation, low labor intensity, no pollution;

How to Choose a Professional Fiber Laser Cutting Machine?

 Professional laser cutting machine supplier to share this article for you. In the professional laser cutting machine, for the parts with higher cutting accuracy or thicker thickness, several key technologies must be mastered and solved. Focus position control is one of them. One of the advantages of laser cutting is that the energy density of the beam is high, so the diameter of the focal spot is as small as possible to produce a narrow slit. Because the smaller the focal depth of the focusing lens, the smaller the focal spot diameter. For high-quality cutting, the effective focal depth is also related to the lens diameter and the material being cut. Therefore, it is important to control the position of the focus relative to the surface of the material being cut.

Such a device has its own selection criteria in the middle of the selection process. In fact, once we choose this device, we must determine the production range, and we must make an effective selection according to the processing material or the thickness of the cut. Only in this way can we determine the number of purchased equipment or the relevant machine model, and do the relevant foreshadowing of the subsequent procurement work. How to choose a professional laser cutting machine will have more choices in this regard standard.

Professional Laser Cutting Machine

1. Fine cutting

When buying, you must also look at their cutting fineness, basically speaking, they can be controlled between 0.1 mm and 0.2 mm.

2. See the deformation of the material

If the laser cutting machine is used for cutting, the material deformation effect of good equipment is very small.

3. The smoothness of cutting surface

In the actual cutting process, the smoothness of the cutting surface is also very important. It is necessary to see if their cutting surface has some burrs. Generally, there will be some burrs, which are basically caused by the thickness of the cutting or The gas used is determined. There is no burr below three millimeters. The gas is good for nitrogen, followed by oxygen. If the air is inside, this effect is also poor. Professional fiber laser cutting machine has relatively few burrs, and it can even be said that the surface without burrs is very smooth.

4. See the power

Most manufacturers have their own power requirements for laser cutting machines and other equipment. From the existing situation, most factories also cut metal plates under six millimeters, and there is no need to buy high-power cutting machines.
