In 2017, China’s new energy auto industry has developed rapidly. According to the news released by the National Federation of Passengers, in November 2017, sales of new energy passenger vehicles reached 74,900 units, an increase of 131.4% year-on-year; according to estimates by the China Association of Automobile Manufacturers, by 2020, China’s new energy vehicles Sales are expected to reach 2 million units. Although the number of new energy vehicles is still dwarfed in the face of car ownership in the country, with the future development trend of China’s automobile technology and increasingly strict fuel consumption regulations, new energy vehicles will become an irreversible development trend.
After the new energy vehicle enters the “rapid development” period, it is foreseeable that the advanced manufacturing technology represented by laser technology will continue to promote the rapid development of the automotive industry while promoting the rapid development of the automotive industry. Especially for laser cutting technology, one of the main applications of the automotive industry, its application prospects will become more and more broad.
Laser cutting uses a high power density green laser pointer beam to illuminate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporates to form a hole. As the beam moves toward the material, the hole continuously forms a slit with a narrow width. Material cutting technology. This cutting technology not only greatly reduces the labor cost, but also meets the increasing individualized needs of users. Currently, it is mainly used for flat sheet cutting and three-dimensional cutting of automobiles. Among them, the surface plate cutting application is wide, covering all aspects such as auto parts, automobile body, automobile door frame, car trunk, and automobile roof cover.
At present, in developed industrial countries such as Europe and the United States, 50% to 70% of automotive parts are processed by laser processing. Its representative laser cutting machine equipment manufacturers such as TRUMPF, Swiss BYSTRONIC, Italy PRIMA, US WHITNEY and Japan TANAKA have developed high-power, large-format, high-speed, flying light paths. Three-dimensional, CNC automatic laser cutting machine. These laser cutting machines are used in various industries such as automobile manufacturing, aerospace and aerospace, and new models are being introduced every year.
China’s laser industry started late, but it is developing rapidly. In recent years, many excellent laser companies such as Dazu, Huagong and Superstar have been born. These enterprises not only make up for the gap in China’s laser industry, but also catch up with the development of laser cutting technology and catch up.
Among them, Huagong green laser pointer focuses on self-study and emphasizes independent innovation. On January 8, 2018, Huagong Laser cooperated with Huazhong University of Science and Technology, Shenlong Automobile, Jianghuai Automobile, Great Wall Motor, SAIC-GM, Jiangling Motors, AVIC Precision Machinery, Lingyun, Wuhan Farley and other units to independently develop the “car”. The project of high-quality and high-efficiency laser welding, cutting key technology and complete sets of equipment in the project won the first prize of National Science and Technology Progress Award at the National Science and Technology Awards Conference held in the Great Hall of the People to realize the key processes of laser welding and cutting in the field of automobile manufacturing. The localization of complete sets of equipment has broken the monopoly history of foreign countries in this field for more than 40 years.
As one of the leading domestic enterprises, Dazu Laser, China’s first elevated gantry three-dimensional five-axis laser processing (cutting, welding, 3D printing) machine tools and thermoformed three-dimensional five-axis laser cutting machine debut CCTV documentary “Great Power II: Launching China, independent research and development surprised everyone, helping China to achieve a magnificent transformation from a manufacturing power to a manufacturing power.
Nowadays, the combination of advanced green laser pointer manufacturing technology and automobile production is the trend of the times. However, in the “eve eve” of new energy vehicles, laser cutting has broad application prospects in the automotive industry, and the market potential is huge. Laser cutting manufacturers should seize this rare opportunity to achieve a take-off in development.
