Laser welding machine for automobile parts | laser welding in automotive industry | laser welding equipment for automobile body Program overview
Nowadays, the inner wall, bottom plate and column of automobile door are all applied to the laser technology. Different steel plates and aluminum plates can be cut into different sizes and shapes by using the laser technology. Then they can be spliced together according to the specific design needs. Compared with the previous processing methods, it not only provides the processing efficiency, but also has a great space for flexibility in processing design, and the process design is also more lean, and the utilization rate of materials is also effectively improved.
For the small parts manufactured in automobile, not only can use the current laser technology, carry out fine seamless welding, but also can use laser technology to mark the product information, which not only improves the stability and safety of the vehicle, but also can carry on the anti-counterfeiting mark and product tracking for the parts.
Automobile manufacturing involves many related industries, is a very large system engineering, and requires a series of technical cooperation. The application of these laser technologies in the automotive field is only some directions of laser technology in the field of automobile manufacturing. With the deepening of the relationship between laser technology and the current automobile manufacturing industry, laser technology in automobile manufacturing The application in the field has involved many industries. Like the optical fiber laser marking machine, laser welding machine and laser cutting machine, it involves many aspects of automobile manufacturing, and its excellent performance advantages are gradually promoting the rapid development of automobile manufacturing industry. Advantages of the scheme
1、 Laser welding Laser welding has become one of the important means in automobile manufacturing because of its advantages of high energy density, small deformation, narrow heat affected area, high welding speed, easy to realize automatic control and no subsequent processing. There are hundreds of thousands of parts in a car body and chassis. How to connect them together has a direct impact on the rigidity of the vehicle body. Laser welding can connect all kinds of metal materials of different thickness, brand, type and grade together, while improving the production efficiency and quality, and increasing the flexibility of vehicle design and material selection.
2、 Laser cutting Laser cutting is one of the common laser processing methods. Laser cutting types are divided into four types: laser vaporization cutting, laser melting cutting, laser oxygen cutting, laser cutting and laser cutting and control fracture. Compared with the traditional machining methods, laser cutting has the advantages of higher cutting quality – narrow width of cut, small heat affected area, smooth cut, fast cutting speed, strong flexibility – arbitrary cutting shape, wide material adaptability and so on. Cutting edge of large automobile cover often needs three-dimensional laser cutting machine. In addition, the current automotive manufacturing platform is becoming more and more intense, which puts forward higher requirements for the flexibility of production line. The 3D laser cutting only needs to adapt the laser processing procedure after the model changes. The tooling is simple and the construction period is greatly shortened, and the cost of manufacturing die is greatly reduced compared with the use of mold. In addition, the application of high-strength steel in automobile is increasing. After hot forming, the stamping process is no longer suitable. The cutting of the profile and hole promotes the demand for laser cutting.
3、 Laser marking In the production of automobile and parts, the establishment of identity is the basis of quality traceability and recall. It is very important to establish the identity of automobile and parts by marking. The automobile marking has been widely used for its high efficiency and adaptability. Laser marking is a marking method which uses high energy density laser to irradiate the workpiece locally, vaporize the surface material or produce color change chemical reaction, thus leaving the mark. Laser marking is characterized by non-contact processing, can be marked on any special surface, and the workpiece will not deform and produce internal stress. Modern automobile parts are made of various materials, including metal, plastic, glass, ceramics, wood and leather, and laser can mark on the surface of all these materials.
