The current era is the era of development, science and technology, and metal manufacturing industry playing an important role. In today's metal manufacturing industry, the application of sheet metal technology is more and more extensive. Since the beginning of the 21st century, the development speed of the sheet metal industry has exceeded everyone's expectations, and its position and share in the market are also rising. This has huge development potential and economic benefits for enterprises, and also has a certain role in promoting the production and living convenience of residents.

Market demand is an internal factor to promote the development of the industry. Due to the continuous improvement of productivity, many technological reforms have been derived, the most prominent of which is laser technology. Around 2010, many foreign enterprises aimed at the Chinese market to seize the market. The market share of foreign resources once reached more than 90%. The development of domestic related industries was difficult. However, with the involvement of laser technology, this situation has been greatly improved. On the one hand, due to the relatively mature domestic technology, on the other hand, the technical requirements of the industry development are constantly improving.

Current development trend of green sheet metal processing

In the sheet metal process, the extensive application of laser technology provides a new economic growth point for the industry development, and it is also of great significance for the technical improvement of the sheet metal process. Due to its superior monochromaticity and directionality, metal laser cutting technology can provide a good technical guarantee for the precise positioning of sheet metal process, and has extremely strong application and development potential in drilling and welding, marking, heat treatment and other aspects. As far as the current sheet metal technology is concerned, applying laser technology to it can not only shorten the working time of sheet metal processing, but also greatly improve the working efficiency of sheet metal processing, At the same time, it can reduce the wear of die to a certain extent, so under the application of laser technology, the development of sheet metal technology is more reasonable and scientific. At present, the data model laser cutting technology in China has formed a scale, and will be more widely used in the future automobile manufacturing, metal material processing, customized mold manufacturing, etc. The promotion and application of new laser technology has provided new development trends for enterprises and industries, and has achieved good results in integrating resources and promoting economic growth.

Introduction and application of a new automatic and flexible production line for sheet metal laser processing

The introduction of a new automatic production line for laser processing of sheet metal will greatly help to improve the process of sheet metal production, break through the bottleneck of current technology development to a certain extent, and maximize the advantages of laser technology, the monochromaticity and balance of the laser are maximized, and the laser processing of soft materials is realized. Through simplifying the laser production process and the access of automatic production lines, the accuracy of laser processing materials is constantly improved. Through the accurate control of temperature, the physical and chemical properties of materials can be changed, which has a certain role in promoting the study of the internal structure of materials. The high temperature conditions provided by laser make the fine operation of metal processing easier, At the same time, the density of materials can be continuously improved through accurate control of temperature, thus promoting the comprehensive performance of materials. Through the introduction of flexible continuous production equipment, the cutting surface of production products can be guaranteed to be flat to the greatest extent. Advanced automation technology has also become the system and core of equipment control. The automatic and flexible control system enables the accuracy of all processing parts to be continuously improved. At the same time, it can reduce the number of personnel on the production line, and continuously improve the processing efficiency. At the same time, it also has some implications for cost saving.

Introduction to Laser Cutting Technology

Compared with the traditional cutting machine, the laser cutting technology has unique advantages. It has a good performance in cutting effect and accuracy, and also guarantees the actual operation and safety factor. In the actual cutting process, the laser cutting speed is fast, the loss of materials is small, and the performance in heating, deformation and other aspects is more prominent. Moreover, cutting has gradually developed from simple binary operation to three-dimensional operation, providing new technical support for material cutting, as shown in Picture 2.

Introduction to Laser Drilling Technology

Since laser drilling is an automatic operation, it can solve holes with a diameter of less than 0.2mm in the actual operation process, which is an impossible challenge for traditional drilling technology. At the same time, it performs well in depth mining, with the deepest depth of 10mm. Such technology can fill the gap in the current drilling technology field to a certain extent, and is very important for mechanical design, as shown in Picture 3.

Introduction to Laser Welding Technology

Laser welding technology is a kind of laser technology with high application frequency. Laser welding can realize zero gap welding between the minimum 2mm parts, improve the stability of welding technology, and provide technical support for reducing the weight of vehicles. At the same time, the safety and structural stability of laser welding technology are higher than traditional welding technology, and are widely used in the field of metal processing, It has become the most widely used welding technology in the automotive field.

Forming defects in sheet metal laser processing and preventive measures

For laser processing metal materials, the defects are the material's own defects and the material's own deformation in the actual processing process caused by the decline in material quality. As far as the laser technology itself is concerned, there is no technical defect. Therefore, the melting point of the metal and the temperature control of the laser must be considered when laser metal processing. The intervention of the cutting process can reduce the transition connection problem inside the metal, and ensure the accuracy of metal processing. A good control of the machining allowance and the rough processing can achieve a full distinction between the two, laying a solid foundation for fine processing.

Conclusion

With the continuous progress of science and technology and the continuous development of economic level, the application of laser processing technology will also be constantly explored. Because of its strong efficiency, energy conservation and environmental protection, it plays a crucial role in the improvement of sheet metal processing technology for enterprises, and also has a certain role in promoting the development of the industry, so it plays a crucial role in the actual market development. However, because the current market development is not standardized, if the laser processing technology wants to be fully and effectively promoted, we should be dissatisfied with the current situation, strengthen innovation, further play the subjective initiative in the process of theory and practice, and strengthen the scientific research and development of laser processing technology.
