1. New energy vehicle
Since the popularity of new energy vehicles, the automotive industry has been one of the most widely used fields of laser processing, which mainly focuses on laser cutting and laser welding. 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 perspective. The automobile manufacturing industry is an industry with very concentrated new technologies. As an advanced technology manufacturing means, laser cutting is very important in the automobile manufacturing process and the automobile parts manufacturing process.
2. Laser cutting technology
Laser cutting technology basically covers all application fields of automobile manufacturing industry. The application scope of laser cutting technology includes: automobile parts, automobile body, automobile door frame, automobile trunk, automobile roof cover and other aspects. In developed industrial countries such as Europe and the United States, 60%~80% of auto parts are processed by laser. Among them, laser cutting is one of the main laser applications. Laser cutting in the auto industry includes plane plate cutting and three-dimensional pipe cutting.
The amount of plate cutting in the automobile industry is relatively large, and the advantages of using laser cutting machine are very obvious:
1. The cost of laser cutting is 80% of that of traditional cutting. If a large number of laser cutting is used to replace the traditional die blanking in China, a large amount of die manufacturing costs can be saved. The laser cutting machine is more flexible to meet the personalized needs and shorten the cycle when cutting plates with large area and complex contour shape in medium and small batches.
2. Laser cutting is controlled by computer, which can accurately cut complex patterns with convenient modification and small error.
3. The laser cutting equipment has a large processing surface and can cut the whole board by nesting, which is not easy to do with other processing equipment.
4. The dimensional accuracy and notch roughness standards of laser cutting exceed those of general mechanical cutting.
