Laser processing technology is the most important manufacturing technology method in the rail car manufacturing industry in recent years, which plays a great role in promoting the technological level of rail cars. The rapid development of China's rail car industry also provides a huge potential application market for laser processing. The application of laser cutting, blanking, welding and other technologies has also pushed the rail car manufacturing technology to a new era.

The development of laser processing technology has led to the progress of the manufacturing level of rail cars. At the same time, the requirements of high-speed and lightweight rail vehicles also continue to provide new topics and research directions for laser processing technology, which has led to the progress of product structure. This article only focuses on laser cutting technology.

Application status of laser cutting technology in rail vehicle manufacturing: as a flexible processing technology, laser cutting has the advantages of high precision, high efficiency, small thermal deformation and strong adaptability. At present, domestic and foreign rail vehicle manufacturers generally use laser processing technology to process stainless steel, carbon steel, aluminum alloy and other metal plates.

The processed products mainly include metal plate parts of car body, bogie and interior parts, most of which are two-dimensional plane cutting. The outline and holes of the parts are processed by laser cutting to obtain high precision and cutting section quality.

Development trend of laser cutting technology in rail vehicle manufacturing three-dimensional laser cutting technology has just been applied in the domestic rail vehicle manufacturing industry, mainly for cutting and hole cutting of various three-dimensional stamping parts.

Generally, 3D laser cutting is equipped with manipulator, optical fiber laser, exchange workbench, closed-circuit real-time monitoring display, closed cutting room, dust removal and programming system. It can realize 3D cutting and hole cutting of various 3D workpieces; The configured exchange workbench can exchange and cut workpieces to improve efficiency. Offline and teaching programming can improve cutting accuracy, realizing safety and environmental protection.

The application of this equipment in production solves the three-dimensional cutting of various complex workpieces and replaces the backward toothless tool and manual plasma cutting process, which not only improves the product quality, but also solves the problem of environmental pollution.

In addition, with the continuous development and wide application of laser cutting technology, laser cutting technology will show the following development trends in rail vehicle manufacturing:

(1) The large-scale laser cutting machine will improve the processing capacity and quality of large workpieces, especially the laser cutting after the components are formed.

(2) The specialization of laser cutting equipment is targeted at carbon steel, stainless steel and aluminum alloy materials, especially materials with different thicknesses. For example, optical fiber laser with appropriate power is used for aluminum alloy cutting to reduce the harm of reflection to the equipment, improve quality, speed and sectional quality, and optical fiber laser cutting with high efficiency and low cost is used for thin plates.

(3) Further innovation and improvement of laser cutting technology with the diversification of demand, higher requirements are put forward for laser cutting technology, which is bound to promote the revolution of laser cutting technology, and more advanced technology and equipment will emerge at the historic moment. At the same time, the wide application of laser cutting technology will also provide effective data and experience for the innovation and improvement of laser cutting technology.

How much is a laser cutting machine?

Many users may find that the prices of laser cutting machines from various manufacturers vary greatly after comparison. Tens of thousands of cheap, millions of expensive. There are many factors that affect the price of laser cutting machines. Of course, the brand size determines the price of equipment, which is a relatively abstract concept. We can understand in this way that the quality of equipment, spare parts of equipment, performance of equipment, technology and after-sales service of large brands will be much more guaranteed than that of small manufacturers. These are an added value of products and a general rule of the laser cutting machine market. Therefore, the price of laser cutting machines of large brands will be higher than that of small brands.
