The advantages of laser cutting technology car body manufacturing process

There are many different kinds of laser cutting machine in the car body structure of the vehicle, according to the materials can be divided into the aluminum alloy car body, stainless steel body and carbon steel car body, etc. In car body manufacturing process, sheet metal cutting blanking as the first working procedure, its material quality for subsequent car body welding quality and welding efficiency, and the production efficiency of the vehicle, has an important influence. Therefore, according to the characteristics of the rail vehicle products, car body of aluminum alloy, stainless steel and carbon steel plate mainly adopts two-dimensional laser cutting technology for high precision blanking, and USES the three-dimensional laser cutting technology of the sheet forming special cutting position. Laser cutting sheet metal pieces belongs to typical laser cutting parts of aluminum alloy sheet parts mostly for the cab structure, its characteristic is the shape structure of variable curvature of curve, each has more than four hundred kinds of models, the car body manufacturing process digital control process of laser cutting equipment, in ensuring the precision of parts at the same time to avoid the problem of low efficiency caused by the variety. Stainless steel and carbon steel plate parts as the main body ChengZaiJian, usually have a large number of irregular structure used in the vehicle suspension parts, welding characteristics of various materials and specifications, use laser cutting blanking can effectively ensure the dimension accuracy of parts and assembly quality, improve production efficiency. Behind special cutting requirements for sheet metal forming parts, three-dimensional laser cutting technology is adopted on the method, its advantages are: (1) accurate, avoid the cut size deviation, is advantageous to the assembly. (2) the surface of the cut surface with high quality, be helpful for welding. (3) high production efficiency, the same parts do not need to repeatedly crossed fixed position, is conducive to the production.
