Auto parts laser welding laser welding machine | car industry | car body laser welding equipment

Solution overview

Now the automotive door wall, bottom plate, column are applied to the current laser technology, using the current laser technology can be different steel plate, aluminum plate cut into different sizes and shapes, and then use laser technology to splicing them together according to the specific design needs. Compared with the previous processing method, not only provides processing efficiency, but also has a lot of room to play the flexibility of processing design, process design is more lean, and also effectively improve the utilization rate of materials.

For small parts in automobile manufacturing, not only can use the current laser technology, fine seamless welding, but also can use laser technology to mark product information, which not only improves the stability and safety of the car, but also can carry out anti-counterfeit identification and product tracking of parts.

Automobile manufacturing involves many related industries, is a very huge system engineering, need a series of technology cooperation, the laser technology application in the field of automobile, is just a laser technology application in the field of automobile manufacturing some of the direction, as now laser technology and the deepening of automobile manufacturing industry become attached to, now The application of laser technology in automobile manufacturing has been involved in many industries. Like the current optical fiber laser marking machine, laser welding machine, laser cutting machine, involving many aspects of the current automobile manufacturing, excellent performance advantages, is gradually promoting the rapid development of the current automobile manufacturing industry.

Plan advantage

First, laser welding

Laser welding has become one of the important means in automobile manufacturing due to its advantages of high energy density, small deformation, narrow heat-affected zone, high welding speed, easy automatic control and no subsequent processing. A car body and chassis consists of hundreds of thousands of parts, how to connect it with rigid has a direct influence on the vehicle body, use laser welding can put almost all the different thickness, brand, type and grade of metal materials together, in raising the production efficiency and quality at the same time also increased the automobile design and the flexibility of material selection.

Two, laser cutting equipment

Laser cutting is one of the commonly used laser processing methods, laser cutting types are divided into laser vaporization cutting, laser melting cutting, laser oxygen cutting and laser scribing and control fracture four categories. Compared with the traditional processing method, laser cutting has the advantages of higher cutting quality - narrow incision width, small heat affected area, smooth incision, fast cutting speed, strong flexibility - can be arbitrarily cut any shape, a wide range of material adaptability. 3 D laser cutting machine is often needed for cutting edge of large automobile panels. In addition, the increasing intensity of the current automobile manufacturing platform, the flexibility of the production line has put forward a higher requirement, the use of THREE-DIMENSIONAL laser cutting in the model of the model after the change only need to adapt the laser processing program, and the tooling is simple, greatly shorten the construction period, compared with the use of mold manufacturing cost significantly reduced. In addition, the application of high strength steel in the automobile is more and more, this kind of steel in hot forming, stamping process is no longer suitable, its contour and hole cutting, promote the demand for laser cutting.

Three, laser marking

In the production of automobile and parts, the identification is the basis of quality traceability and recall. It is very important to establish the identification of automobile and parts through marking. Automobile marking is more and more widely used because of its high efficiency and adaptability. Laser marking is a marking method which uses high energy density laser to irradiate the workpiece locally and make the surface material vaporize or undergo color change chemical reaction, thus leaving a mark. Laser marking features non-contact processing, can be marked on any abnormal surface, the workpiece will not be deformed and produce internal stress. Modern car parts are made of a variety of materials, including metal, plastic, glass, ceramic, wood and leather, and lasers can be used to mark the surfaces of all these materials.
