Laser cutting includes plane cutting and three-dimensional cutting. For some high-strength steel structural parts with complex contours, three-dimensional laser cutting is a very effective processing method, whether from a technical or economic point of view.
 

Application of laser technology in automobile industry

In the automobile industry, laser technology is mainly used for body welding, welding and parts welding. Laser metal tailor-welding is to select steel plates of different specifications according to different design and performance requirements of the vehicle body during the design and manufacturing of the vehicle body, and complete the manufacturing of a certain part of the vehicle body through laser cutting and assembly technology, such as the front windshield frame, the inner door panel, the underbody, the neutral column, etc.

In the traditional trial production stage, the trimming and hole cutting of stamping parts can only be completed by hand. Generally, at least two or three processes are required, and the processing time is long. Moreover, manual processing cannot guarantee the repeated accuracy of cutting parts, and it is difficult to meet the objective requirements of shorter and shorter vehicle development cycle. The application of 3D metal laser cutting machine enables the machine tool to automatically "adapt" to the error caused by the elastic deformation of stamping parts, thus making 3D laser metal cutting technology truly become a new precision and flexible processing method for automobile body processing.

Cutting principle of 3D laser metal cutting

Three-dimensional fiber laser cutting machine is an advanced laser cutting equipment that uses special fiber laser cutting head, high-precision capacitive tracking system, fiber laser and industrial robot system to conduct multi-angle and multi-directional flexible cutting of metal plates with different thickness. It makes use of the flexible and fast action performance of industrial robots. According to the size of the workpiece cut and processed by users, it carries out 3D cutting of irregular workpiece through optical fiber laser cutting head by carrying out front or reverse assembly of the robot, teaching or offline programming for different products and different tracks; The laser is transmitted to the cutting head by optical fiber (the optical fiber laser cutting head is equipped with a special optical fiber servo device and optical path transmission device), and then the focusing system is used to focus, which can cut a variety of three-dimensional metal plates in multiple directions.

The application of 3D metal laser cutting machine has reduced the investment cost of mold, greatly shortened the development cycle of automobile manufacturers and parts suppliers, and improved the processing efficiency and cutting accuracy of workpiece. It is a powerful tool for automobile manufacturers and parts suppliers to improve their competitiveness.

Advantages of 3D laser processing

A prominent advantage of 3D laser processing is that it greatly reduces the production cost of products. Suppose that a car needs 10 body panels. If the conventional punching die is used for production, the cost of the required die is very high, and the man-day workload of all tooling preparation, design and commissioning takes a long time. If three-dimensional metal laser cutting equipment is used, the total cost will be greatly reduced and the product development cycle time will be shortened.

Three-dimensional metal laser cutting can accomplish tasks that can only be completed by traditional plasma manual cutting, trimming die, punching die, six-axis robot three-dimensional cutting machine and wire cutting, and truly realize intelligent, multi-function, high-efficiency, low-energy flexible processing. The innovation of tools brings about the improvement of production efficiency and product quality. The 3D laser cutting machine can not only drive the development of the automobile industry, but also bring the gospel of the special-shaped material cutting industry.

It can be seen that in the field of automobile manufacturing, the application of laser processing technology makes the automobile manufacturing process with high precision, good quality and easy to realize automation, flexibility and intelligence; More importantly, it can improve the safety and quality of cars, clean production and reduce consumption and pollution, reduce costs and ultimately give preferential treatment to ordinary consumers.
