Why does automobile manufacturing need laser processing

  After entering the 21st century, in the automotive industry of Japan, the United States and Europe, people pay more and more attention to maintaining their competitiveness in the market, especially the R & D ability. Small batch production and customized production have become a development direction. This production mode combines the advantages of manual manufacturing and mass production, and avoids the disadvantages of high cost of manual production and lack of flexibility of mass production.

  Under this condition, the manufacturers of laser processing equipment must constantly carry out technological innovation on their products and maintain their product competitiveness. In the design, they should not only pay attention to meet the needs of current automobile panel processing and application, but also prepare for the future development of users, that is, to provide reasonable solutions for small batch production mode in advance. In recent years, automobile body industry users have shown strong demand for the following three aspects of equipment performance improvement: faster processing speed, larger processing range (especially the current very successful MPV, SUV, pickup truck for this aspect demand is more intense), and has the characteristics of flexibility, compact structure, simple operation, etc., an industrial company specializes in its flagship type III A new design of laser processing machine tool has been made. It adopts gantry frame structure, all moving parts are in the air, and the whole processing area is open to users, which has very good accessibility. Users can choose various configuration schemes from manual to automatic according to their own products. In terms of dynamic performance, it has reached an unprecedented level. At the same time, the integrated structure design not only makes the installation simple and rapid, but also has the function of rapid installation and rapid relocation between different production departments, just like the emerging lathes and grinders.

  With people's higher and higher requirements for automobile comfort and safety, increasing body size, considering the use of four-wheel drive technology, and increasing more electronic equipment are becoming more and more popular in the automotive industry. All of these will inevitably increase the weight of the vehicle and lead to the contradiction between the goal of reducing fuel consumption. The only solution is to increase the weight of the vehicle Reduce the weight of the body without affecting the performance. This can be verified by the wide application of Ihu and warm formed steel in the field of automobile body.

  Internal high pressure molding is to make the outer wall of hollow parts (mainly tubular parts) in the mold completely close to the mold through high-pressure emulsion (water and additives). The parts produced by this method have high precision and light weight, and many pipes need to be welded can be formed at one time, which reduces the welding times and improves the overall strength. Its good strength weight ratio and low production cost make it widely used in the body and chassis structure. Due to the complex shape of the internal high pressure forming parts, and there are a certain number of holes and slots to be cut, so the traditional punching die can not be processed. Three dimensional laser cutting is one of the best solutions at present.

  High hard steel material (warm forming steel) has very high internal tension (1500MPa / mm2), so its elastic deformation is very small. It is very suitable for the parts of automobile body with high strength requirements, such as bumper bracket, front beam, side beam, reinforcing rib, etc. Under the same strength requirements, the weight of high hard steel is much lighter than that of normal steel plate, and many welding procedures can be reduced. Therefore, the weight of vehicle body can be effectively reduced under the premise of ensuring safety. Because of this, the parts of this material can hardly be processed by traditional punching die, and the only solution is 3D laser cutting.
