The three-dimensional five axis laser cutting machine is regarded as the pearl on the crown of high-power laser processing equipment. It is mainly used for cutting holes and trimming three-dimensional irregular surfaces, replacing punching and trimming dies.
In the early days, manual plasma cutting of three-dimensional workpieces was used in China, but 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 some extent. However, due to the low accuracy of robots and cutting accuracy, they have only been applied in some industries with low requirements.
In the automotive stamping mold industry, there is a high demand for cutting accuracy in the trial mold. The three-dimensional five axis fiber laser cutting machine tool is popular due to its high production efficiency and stable performance, but the main market is monopolized by foreign equipment, such as Trumpf (Germany), Prima (Italy), NTC (Japan), Mitsubishi (Mitsubishi) and other companies.
Three dimensional five axis optical fiber laser cutting machine is a high-end machine tool equipment integrating light, machinery, electricity and gas. It is used in the automotive industry, mold industry, military industry, aerospace industry, household appliances industry and special-shaped pipe cutting, and is mainly suitable for curved Elasmaria metal cutting.
The 3D five axis laser cutting technology has been developed since the 1990s, with only two manufacturers, Trumpf from Germany and Prima from Italy, monopolizing the market. After 2008, NTC and Mitsubishi in Japan developed a low acceleration, low speed, and high-precision 3D five axis CO2 laser cutting machine with a mobile workbench.
But for a long time, 3D five axis laser cutting machines have been mainly used for research and development and small-scale trial production, to trim and cut holes on stamped 3D parts, replacing traditional trimming and punching molds, shortening the development cycle of new products, and reducing manufacturing costs. Therefore, the annual market sales are relatively small. In the Chinese market, the average annual market demand is around 30-40 units.
In recent years, due to the emergence and application of automotive hot forming technology, the situation of low market demand has been changed. A car hot forming production line is generally equipped with 4-5 three-dimensional five axis laser cutting machines, and the market demand is developing explosively. As of now, there are nearly 450 automotive hot forming production lines worldwide, and there are approximately 2000 sets of 3D five axis laser cutting machines produced along with supporting facilities. There are nearly 170 hot forming production lines in China, and approximately 700 sets of 3D five axis laser cutting machines are produced along with the supporting facilities.
Steel plate hot forming technology refers to the process of forming a steel plate after being heated at a high temperature of 950 ℃, followed by rapid cooling, thereby comprehensively improving the strength of the steel plate, with a yield strength of over 1000Mpa. After being used on the vehicle body, the weight of the vehicle does not increase, but the load-bearing capacity is increased by 30%, and the safety performance is significantly improved. Due to the high strength of the steel plate, traditional trimming and punching molds cannot be used for trimming and punching due to the high strength of the steel plate, and can only be produced using laser. As a result, three-dimensional five axis laser cutting products enter the automotive mass production line, becoming an irreplaceable production process and process.
The yield strength of ordinary steel plates is 140Mpa, suitable for tourist and cable cars; The yield strength of high-strength steel plates is between 180-240Mpa, suitable for trucks, forklifts, buses, excavators, agricultural machinery, etc; The yield strength of high-strength steel plate is between 260-320Mpa, suitable for economy sedans and SUVs; The yield strength of high-strength steel plate is between 340-700Mpa, suitable for high-end sedans and SUVs; The yield strength of hot-formed steel plates exceeds 1000Mpa, while the yield strength of hot-formed steel plates is generally around 1500Mpa.
At present, material manufacturers are developing hot formed steel plates with a yield strength of around 2000Mpa, and increasingly ultra-high strength steel plates are widely used in the automotive industry. This has led to more and more applications of 3D five axis laser cutting machine products.
