The laser cutting process of sheet metal workshop adopts CO2 laser or YAC laser to carry out 2D and 3D cutting, and has the characteristics of high cutting accuracy. Laser power has different sizes, ranging from 5W to 90kW. The laser cutting of sheet metal parts mainly uses 100W to 1500W power laser. When the output power of the laser source is less than 1500W, the laser source is a mode of single mode oscillation and can be cut in the width of the 0.2mm. It is clean and smooth after the power cutting. When the output power of the laser source is greater than 1500W, the laser source is a multi mode oscillation mode, and the width of the 1mm can be cut, but there will be a small amount after the power cutting. Dirt.
Auxiliary gas should be used in cutting thick plates, and auxiliary gases include air, oxygen and nitrogen. Nitrogen can prevent the oxidation of the cutting surface during the cutting process, and the oxygen is suitable for high speed cutting in the larger thickness plate. CAD or CAM technology can be used in laser cutting of sheet metal workshop to provide processing information and processing parameters for machining work piece model and laser. It can complete production quickly and high precision and realize automatic cutting. Laser cutting is especially needed to replace the mould repeatedly, which can shorten the production preparation period and reduce the production cost.
As a new technology, laser cutting technology of sheet metal workshop is a product of modern scientific development. Laser cutting, laser welding, laser drilling technology and laser forming technology also require skilled personnel to manipulate in the production and processing of sheet metal cars. With the development of laser material processing technology, the production and processing of sheet metal workshop will achieve stability, reliability, high efficiency and high automation.
