What are the characteristics of high pressure forming technology in automotive stamping parts?

Nowadays, the primary task of sheet metal fabrication is to reduce costs and improve product quality. Compared with other fabrication technologies, internal high pressure forming technology has significant technical and economic advantages in this regard. The internal high pressure technology can not only produce parts with very complex shapes, but also the quality of the parts produced is very light compared with other construction processes, and the forming accuracy is also high. In addition, the internal high pressure forming technology can also improve the rigidity of the formed parts, which is also very important.

The blanks for internal high pressure forming are mainly tube blanks with a circular cross-section. During the production process, if the geometric shape cannot be expanded to the required size due to the design requirements, the workpiece needs to be further processed to improve the production process. workpiece. The application of internal high pressure forming technology is very extensive. Due to the diversity of its design and structure, it is favored by technicians in the fabrication of parts with high working strength, long service life and very light weight. , This technology has been applied to the manufacture of gasoline engine exhaust systems of many automobiles, and will be more and more applied to the fabrication of various parts of automobiles.

The parts processed by hot forming technology not only have high strength and precision, but also have small springback, which makes the application of hot forming technology more and more widely.

Of course, hot forming technology still has shortcomings that it cannot overcome. Because it is a new type of fabrication technology, some aspects are not yet mature and need further improvement by researchers. The subsequent fabrication of auto parts processed by hot forming is very difficult, and due to the frequent sudden changes in temperature and the softening effect of high temperature, the hot forming mold often has plastic deformation failure and fatigue aging of the sheet metal. In other cases, the service life of the mold is reduced.
