In recent years, 3D laser tube cutting technology has developed rapidly, and its application fields have become more and more extensive, especially in the automotive, mold and aerospace manufacturing industries. In the automotive industry, the use of three-dimensional laser tube cutting technology to cut body tube parts can replace the trimming die and punching die in the traditional manufacturing process. The process steps are simple, the manufacturing cycle is short, the cutting speed is fast, the slit width is small, the processing quality is high, and the cost can be greatly reduced. Shorten the development cycle of new models. It has good economic value and application prospects. There are two types of 3D laser cutting equipment commonly used in the industry: 3D laser cutting machine tools and laser cutting robots. The 3D laser cutting machine has good rigidity, fast processing speed and high processing accuracy, but the laser head has poor ability to approach the processing area and is expensive. Although the laser cutting robot has high flexibility, it enhances the ability of the laser head to approach the processing area, and can use high-power solid-state lasers transmitted by optical fibers for high-flexibility processing. However, it is not as good as a three-dimensional laser cutting machine in terms of processing speed and processing accuracy. Therefore, in order to improve the cutting accuracy and cutting quality, the world’s major automobile companies generally use three-dimensional laser cutting machine tools.
At present, many foreign automobile manufacturers widely adopt laser tube cutting technology. It is mainly used for the development of new models, online pipe cutting, and the production of deformed vehicles. For example, cutting prototype car parts. Cutting holes, trimming, cutting steering wheel holes, windshield panels, roof support holes, airbag parts, liquid limit forming parts, etc. In the prototype development and small batch production, the three-dimensional laser cutting tube processing system is used to cut various Sheet. On the production line, laser cutting robots are used to perform online three-dimensional cutting of stamping parts. Application of high-efficiency laser cutting china system. Greatly shorten the time for new car development and the preparation period for car production. The production has been automated and flexible, and the production efficiency has been greatly improved. In the heyday of American automobile development, there were more than 500 laser pipe cutting machines in Detroit, USA, which were engaged in trimming, opening and blanking of various body stamping parts.
Nowadays, automobile consumption emphasizes personalization, and the model update cycle is getting shorter and shorter. The original mold production is difficult to adapt to faster and faster mold changes due to its own limitations-the mold production cycle is very long. The use of laser tube cutting and modular rapid bottoming technology has a huge competitive advantage. However, 3D laser cutting equipment has been imported for a long time, not only the overall price is high. Moreover, the parts are expensive, and maintenance must be controlled by others, although my country’s research on 3D laser tube cutting technology started relatively late. It is encouraging that more and more research institutions and universities have joined this rank.
