Pressurizing aging forming method and device for plate

The invention discloses a pressurizing aging forming method and device for a plate, and relates to the technical field of plate forming. The plate is subjected to solution treatment firstly, a base body structure in a supersaturated state is obtained, and structure preparation is made for plastic deformation conversion; an upper die and lower die temperature control device of a tool is started, heating is conducted to an aging temperature, then the plate subjected to solution treatment is put into a die, an upper die is moved through a hydraulic device, pressurizing is conducted, and an artificial aging stage is conducted; the plate is in a compressed deformation state by increasing the pressure, and unloading is conducted after pressure maintaining is conducted for a period of time; the position of the upper die is kept after unloading, the plate is shaped in a forming face for a period of time, residual stress is reduced, and the temperature of the die is kept constant in the whole process; and the upper di
