Now there are laser technologies applied to the inner wall, bottom plate and column of automobile doors. Different steel plates and aluminum plates can be cut into different sizes and shapes by using the current laser technology, and then they can be spliced together according to the specific design needs by using the laser technology.Compared with the previous processing methods, it not only provides the efficiency of processing, but also has a lot of room for the flexibility of processing design, and the process design is more lean, and also effectively improves the utilization rate of materials.
For the small parts manufactured in the automobile, not only can the laser technology be used to carry out fine seamless welding, but also the laser technology can be used to mark the product information, which not only improves the stability and safety of the automobile, but also can carry out anti-counterfeiting identification and product tracking for the parts.
Automobile manufacturing involves many related industries. It is a very large system engineering, which requires a series of cooperation of process technology. The application of these laser technologies in the automobile field is just some directions of laser technology in the automobile manufacturing field. With the deepening of the relationship between the current laser technology and the current automobile manufacturing industry, the laser technology in the automobile manufacturing industryThe application in the field has involved many industries.Like the optical fiber laser marking machine, laser welding machineand laser cutting machine, they involve many aspects of automobile manufacturing. Their excellent performance advantages are gradually promoting the rapid development of automobile manufacturing industry.
1、 Laser welding machine
Laser welding has become one of the most important means in automobile manufacturing because of its advantages such as high energy density, small deformation, narrow heat affected zone, high welding speed, easy to realize automatic control and no subsequent processing.There are hundreds of thousands of parts in a car's body and chassis. How to connect them has a direct impact on the rigidity of the car's body. Almost all metal materials of different thickness, brand, type and grade can be connected together by laser welding, which not only improves the production efficiency and quality, but also increases the flexibility of car design and material selection.
2、 Laser cutting machine
Laser cutting is one of the most commonly used laser processing methods. Laser cutting is divided into four types: laser vaporization cutting, laser melting cutting, laser oxygen cutting, laser scribing and controlled fracture.Compared with the traditional machining methods, laser cutting has the advantages of higher cutting quality - narrow cutting width, small heat affected area, smooth cutting, fast cutting speed, strong flexibility - arbitrary cutting shape and wide material adaptability.Three dimensional laser cutting machine is often used to cut the cutting edge of large automobile panel.In addition, the current automobile manufacturing platform is becoming more and more fierce, which puts forward higher requirements for the flexibility of the production line. The three-dimensional laser cutting only needs to adapt the laser processing procedure after the model change, and the tooling is simple, greatly shortens the construction period, and the manufacturing cost is greatly reduced compared with the mold.In addition, the application of high-strength steel in automobile is more and more. After hot forming, the stamping process is no longer suitable for this kind of steel. The cutting of its contour and hole promotes the demand of laser cutting.
3、 Laser marking machine
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 uniqueness of automobile and parts identity through marking.Automobile marking has been widely used for its high efficiency, adaptability and permanence.Laser marking is a kind of marking method which uses high energy density laser to irradiate the part, vaporize the surface material or change the color, so as to leave a permanent mark.Laser marking is characterized by non-contact processing, which can be engraved on any special-shaped surface without deformation and internal stress.Modern auto parts use a variety of materials, including metal, plastic, glass, ceramics, wood and leather, and laser marking can perfectly mark the surface of all these materials.
