The automotive manufacturing industry is an industry with a high-tech concentration. Laser cutting, as an advanced process manufacturing method, basically covers all application fields in the automotive manufacturing industry, such as automotive parts, automotive bodies, automotive door frames, automotive trunks, automotive roof covers, etc. In the automotive manufacturing industry, laser cutting is mainly concentrated in the field of medium and thin plate processing, involving processes including plate laser cutting, three-dimensional laser cutting and tube laser cutting.
In many countries in the world, 50%~80% of automotive parts are completed by laser processing. There are many automotive parts, a large number of plate processing, and high requirements for cutting quality. Compared with traditional processing technology, the advantages of laser cutting are very obvious.
① For the production of small and medium batches, large areas and complex contours of automotive parts, laser cutting is more flexible and can meet personalized needs.
② Laser cutting is controlled by computer, which can accurately cut complex patterns, and is easy to modify and has small errors, which can improve the utilization rate of materials.
③ Laser cutting has high precision, positioning accuracy is about 0.05 mm, and dimensional accuracy and incision roughness standards are better than general mechanical cutting.
④ Laser cutting has a fast processing speed. Taking a 3000 W laser cutting machine as an example, the processing speed of a 1 mm thick stainless steel plate can reach 30 m/min, which is difficult to achieve with other traditional processing methods.
⑤ Reduce the development cost of new products. The trial production of new products is generally small in quantity and the product structure is uncertain, while laser cutting does not require the development of molds, which reduces production costs.
⑥ Laser cutting does not directly contact the workpiece, which can avoid damaging the workpiece surface; at the same time, the thermal impact of laser cutting is very small, which can ensure a high cutting quality.
In the automotive manufacturing process, fiber laser cutting machines work in conjunction with other key equipment, including:
Used in conjunction, the welding of automobile parts can be realized and the welding accuracy and efficiency improved.
Works in conjunction with fiber laser cutting machines for exhaust system manufacturing, body structure processing, air conditioning and refrigeration systems, and auto parts production.
It is used to bend and shape laser-cut parts. It is suitable for parts with complex shapes that need to be bent, and improves the accuracy and assembly of parts.
