The three-dimensional five-axis fiber laser cutting machine is regarded as the crown jewel of high-power laser processing equipment. It is mainly used in the cutting and trimming of three-dimensional special-shaped curved surfaces, and is used to replace punching and trimming dies. In the early days, manual plasma cutting of three-dimensional workpieces was used in China, and the cutting effect was not ideal. In recent years, robot 3D laser cutting machines have been developed in China, and the cutting effect has been improved to a certain extent. However, due to the low precision of robots and low cutting precision, it has only been used in some industries with low requirements. In the automotive stamping die industry, the mold trial requires high cutting accuracy. The three-dimensional five-axis fiber laser cutting machine is popular because of its high production efficiency and stable performance, but the main market is monopolized by foreign equipment.

The three-dimensional five-axis fiber laser cutting machine is a high-end machine tool that integrates light, machinery, electricity and gas. It is used in the automotive industry, mold industry, military and aerospace industries, household appliances industry and special-shaped pipe cutting, mainly for curved surfaces. Sheet metal cutting.

The three-dimensional five-axis laser cutting technology has been developed in the 1990s, and only German, Italian and other companies are developed and produced, and the market is basically monopolized by these two companies. After 2008, Japan's NTC and Mitsubishi developed a low-acceleration, low-speed, high-precision three-dimensional five-axis CO2 laser cutting machine with a mobile table. But for a long time, the three-dimensional five-axis laser cutting machine is mainly used for research and development and small batch trial production. It trims and cuts the stamped three-dimensional parts, replaces the traditional trimming die and punching die, shortens the development cycle of new products, reduces the Manufacturing costs, so the annual market sales are less. In the Chinese market, the general annual market demand is around 30-40 units.

However, due to the emergence and application of automotive thermoforming technology, the market demand has changed. An automotive thermoforming production line is generally equipped with 4-5 three-dimensional five-axis laser cutting machines, and the market demand is developing explosively. Up to now, there are nearly 450 automotive thermoforming production lines in the world, and about 2,000 sets of 3D five-axis laser cutting machines are produced along with them. There are nearly 170 thermoforming production lines in China, and about 700 sets of three-dimensional five-axis laser cutting machines are produced along with it.

The hot forming technology of steel plate refers to that the steel plate is heated at a high temperature of 950℃and then formed once, and then rapidly cooled, so as to improve the strength of the steel plate in an all-round way, with a yield strength of more than 1000Mpa. 30%, the safety performance is significantly improved. Due to the high strength of the steel plate, the traditional trimming die and punching meme cannot be used for trimming and punching due to the high strength of the steel plate, and can only be produced by laser, so that the three-dimensional five-axis laser cutting products enter the mass production line of automobiles, which is impossible. Alternative production processes and procedures.

The yield strength of ordinary steel plates is 140Mpa, which is suitable for sightseeing cars and cable cars; the yield strength of high-strength steel plates is 180-240Mpa, which is suitable for trucks, forklifts, buses, excavators, agricultural machinery, etc.; the yield strength of high-strength steel plates is 260- 320Mpa, suitable for economical cars and economical SUVs; the yield strength of super-strength steel plates is 340-700Mpa, suitable for high-end cars and high-end SUVs; and the yield strength of hot-formed steel plates exceeds 1000Mpa or more, generally hot-formed steel plates. The yield strength is around 1500Mpa. At present, material manufacturers are developing hot-formed steel sheets with a yield strength of around 2000Mpa, and more and more ultra-high-strength steel sheets are widely used in the automotive industry, which makes three-dimensional five-axis laser cutting machine products more and more widely used.
