Abstract
The present invention provides a die capable of achieving rapid forming and quenching therein. The die includes an upper die, a blank holder and a lower die, where the upper die is composed of an internal solid die core and a thin-walled skin. Grooves in communication with each other are disposed between the internal solid die core and the thin-walled skin. In a forming stage, the grooves are not filled or filled with a heat insulating material such as a gas; and in a quenching stage, a low-temperature medium is introduced into the grooves. The die can be used to achieve rapid forming and quenching of metal materials of different types and thicknesses.
