Laser cutting is to focus the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam shines on the surface of the workpiece to make the workpiece reach the melting point or boiling point, while the high-pressure gas coaxial with the beam will blow away the molten or vaporized metal. With the movement of the relative position of the beam and the workpiece, the material will eventually form a slit, so as to achieve the purpose of cutting.
Laser cutting processing uses invisible beams to replace traditional mechanical knives. It has the characteristics of high precision, fast cutting, not limited to cutting patterns, automatic typesetting to save materials, smooth incision, low processing cost, etc., and will gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser cutter head has no contact with the work and will not scratch the working surface during the work; The laser cutting speed is fast, the incision is smooth and flat, and there is generally no need for subsequent processing; The cutting heat affected zone is small, the plate deformation is small, and the cutting seam is narrow (0.1mm~0.3mm); The notch is free of mechanical stress and shearing burr; High machining accuracy, good repeatability, and no damage to the material surface; NC programming, can process any plan, can cut the whole board with large format, no need to open a mold, economical and time-saving.
Application industry of laser cutting machine:
1. Decoration industry
Because of the fast speed and flexible cutting of the laser cutting machine, many complex graphics can be rapidly formed, which is very popular with decoration companies. As long as it is what customers want, they can directly use relevant materials to cut out after drawing through CAD, and customization has no problems.
2. Automobile industry
Many corners in the automotive industry, such as car doors and exhaust pipes, need to be processed after forming. If manual work is used, then **/* The precision is difficult to achieve, and the second efficiency is very high. The robot laser cutting machine can be used for rapid batch processing.
3. Advertising industry
The advertising industry has a lot of customization, and the efficiency of using traditional methods is very low. The laser cutting machine is very suitable for this industry. No matter what kind of characters, no matter how many different companies, they can quickly cut them out.
4. Kitchenware industry
Now there are more and more houses, more and more decoration, and more and more demands for kitchenware related products. The laser cutting machine is very suitable for cutting sheet stainless steel, with fast speed, high precision, and good effect. It can also realize customized and personalized product development, which is popular with kitchenware manufacturers.
5. Lighting industry
At present, the mainstream outdoor lamps are all large tubes, cut in different types, and more and more retro products, more and more types. The traditional cutting method is too inefficient, and can not achieve personalized development. The use of laser cutting machine just solves this problem.
6. Sheet metal processing
In short, processing is all kinds of plates, all kinds of different graphic parts cutting. The advantages of laser cutting machine are incisively and vividly developed in this industry.
7. Cabinet industry
The power distribution cabinet, file cabinet, etc. are all sheet metal standardized production, which requires efficiency. The laser cutting machine with four or six stations is very suitable for high efficiency. For specific sheet metal, it can even cut double-layer.
8. Fitness equipment
Due to the national emphasis on sports health and the development of personal health concept, square fitness equipment and household fitness equipment have developed rapidly, and the demand is particularly large. Most of them are pipe cutting. The use of pipe laser cutting machine is very convenient and fast.
Treatment method of smoke and dust generated by laser cutting machine:
1. Exhaust treatment:
The air exhaust treatment of laser cutting machine is generally aimed at local operations. For example, the general air exhaust facilities are used at the fixed positions of the operators, so that local workplaces are not polluted by harmful substances. However, the effect of this method is very low, because the smoke and harmful gases of laser cutting are air media, and they are swept from the source to the entire production environment.
2. General ventilation:
General ventilation includes natural ventilation and mechanical ventilation. In foreign countries, for outdoor numerical control cutting operations or open space numerical control cutting, natural ventilation is generally used. For indoor operations, mechanical ventilation is usually used. Welding smoke in the workshop is discharged out of the room through axial flow fans installed on the wall or ceiling, or recycled in the workshop after purification by a purifier, so as to reduce the smoke concentration in the workshop.
3. Industrial dust remover smoke treatment:
In the process of processing, appropriate smoke purifiers are used to effectively handle the smoke and dust, which is also a method that currently meets the national environmental protection requirements. A dust collector is set under the laser cutting workbench and collected into the dust removal box of the industrial dust remover through the pipeline. The smoke and dust generated by cutting will not be swept into the processing workshop, which not only ensures the cleanliness of the workpiece, but also ensures the health of workers.
