As the customization structure of automobile hardware processing is becoming more and more complicated, the size is gradually increasing, there are more and more related side parts, the carrying capacity is increasing, and the internal stress limit is getting stricter. It is becoming more and more harsh, so traditional stamping technology can no longer meet the demand, which has promoted the development of special stamping and shaping technology.

Special stamping and forming technology refers to hydraulic forming, precision forming, explosive forming, rotating forming, no model forming, laser forming and electromagnetic forming technology. The car stamping parts made from them are better. In terms of hydraulic forming technology, it is more advantageous than other stamping technology.

When manufacturing cars, large -scale complex three -dimensional geometric stamping parts such as one -time processing shaft, top cover, and door frame can be used during the hydraulic forming process. In order to obtain the intensity of workpieces with higher stamping processes, this allows the use of thinner plates and achieves lightweight goals for precision hardware processing.

During the hydraulic internal high -pressure forming process, the outer surface of the car rushing parts is only contacting the pressure liquid, so the pressure process is relatively gentle, and the formation of parts is uniform. Therefore The outer surface.
