In recent years, due to the requirements of energy saving and lightweight, hydroforming technology has been widely used in automobile manufacturing with a series of advantages. Compared with ordinary processing technology, hydroforming technology can not only form duplicate parts but also improve the quality and life of parts, reduce processes and reduce costs. At the moment when automobile lightweight has become a trend, hydroforming technology will undoubtedly play an important role.
According to the characteristics of automobile processing, hydroforming technology can generally be divided into pipe hydroforming technology and sheet metal hydroforming technology.
Application of Sheet Metal Deep Drawing Technology in Automobiles:
Application of Hydroformed Pipe Fittings in Automobiles:
1. Exhaust system parts, such as intake pipes, exhaust tailpipes, etc. If this type of special-shaped tube is produced using traditional processing methods, more processes are required. And more processes mean high costs and may increase additional weight. However, if the hydraulic forming technology is used, it can be formed at one time, saving manpower and material resources.
2. Bearing parts, such as frame longitudinal beams, rear axle beams, etc. This type of part has high requirements for strength and rigidity. In the past, stamping and welding were used, which not only required a large workload but also made it difficult to ensure the uniformity of performance required by the load. Hydroforming technology can avoid these. In addition, fatigue strength can be improved.
