Application of 3D laser cutting in automobile manufacturing
2024-11-19
Laser cutting includes plane cutting and 3D cutting. For some high-strength steel structural parts with complex contours, 3D laser cutting is a very effective processing method from a technical and economic point of view. In the automotive industry, laser technology is mainly used for body welding and parts welding. Laser welding is to select steel plates of different specifications according to the different design and performance requirements of the body, and complete the manufacturing of a certain part of the body through laser cutting and assembly processes, such as the front windshield frame, door inner panel, car bottom, center pillar, etc. In the traditional trial production stage, the trimming and opening of stamping parts can only be done manually. Generally, at least two to three processes are required, and the processing time is long. Moreover, manual processing cannot guarantee the repetitive accuracy of the cut parts, and it is difficult to meet the objective requirements of the increasingly shorter vehicle development cycle.
The application of 3D laser cutting machine enables the machine tool to automatically "adapt" to the errors caused by the elastic deformation of stamping parts. The 3D fiber laser cutting machine is an advanced laser cutting equipment, which consists of a dedicated fiber laser cutting head, a high-precision capacitive tracking system, and a fiber laser and industrial robot system for multi-angle and multi-directional flexible cutting of metal plates of different thicknesses. Taking advantage of the flexible and fast motion performance of industrial robots, the robot can be installed in the front or inverted position according to the size of the workpiece to be cut by the user, and different products and different trajectories can be taught or programmed offline. The fiber laser cutting head can be used to perform three-dimensional cutting of irregular workpieces; the laser is transmitted to the cutting head through optical fiber (the fiber laser cutting head is equipped with a dedicated fiber servo device and optical path transmission device), and then focused by the focusing system, which can cut various three-dimensional metal sheets in multiple directions.
Three-dimensional laser cutting takes advantage of the flexible and fast motion performance of industrial robots. According to the size of the workpiece to be cut by the user, it can be installed in the front or inverted position, and different products and different trajectories can be taught or programmed offline. The sixth axis of the robot is loaded with a fiber laser cutting head to perform three-dimensional cutting of irregular workpieces; the fiber laser cutting head is equipped with a follower device and an optical path transmission device. The laser is transmitted to the cutting head using optical fiber, and then focused using a focusing system. For plates of different thicknesses, multiple sets of focusing systems have been developed, which can cut a variety of three-dimensional metal plates in multiple directions to meet customer needs. The application of three-dimensional laser cutting machines reduces the investment cost of molds, greatly shortens the development cycle of automobile manufacturers and parts suppliers, and improves processing efficiency and the accuracy of cutting workpieces. It is a powerful tool for automobile manufacturers and parts suppliers to improve their competitiveness. One of the outstanding advantages of 3D laser processing is that it greatly reduces the production cost of products. Suppose a car requires 10 body panels. If traditional punching dies are used for production, the cost of the required molds is very high, and the manual workload of all mold preparation, design and debugging takes a long time. If 3D laser cutting equipment is used, the total cost will be greatly reduced and the product development cycle will be shortened.
3D laser cutting machine can complete tasks that can be completed by traditional plasma manual cutting, trimming die, punching die, cutting and other multi-processes, six-axis robot stereo cutting machine and wire cutting, truly realizing intelligent, multi-functional, high-efficiency, low-energy flexible processing. The innovation of tools has brought about the improvement of production efficiency and product quality.
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 automobile manufacturing have the characteristics of high precision, high quality, high quality, easy automation, flexibility and intelligence; more importantly, it can improve the safety and quality of automobiles, clean production, reduce losses and pollution, reduce costs, and ultimately provide discounts to ordinary consumers.
