Hot forming device and method for aluminum alloy thin-wall large-size end socket structural part

The invention relates to a hot forming device and method for an aluminum alloy thin-wall large-size end socket structural part, and belongs to the technical field of forming of aluminum alloy end socket structural parts. The hot forming device and method solve the problems of instability, wrinkling and cracking during forming of the aluminum alloy thin-wall large-size end socket structural part caused by a deep drawing process in the prior art. The hot forming device comprises a female die, a sealing cover, an air supply unit, an upper hot forming platform and a lower hot forming platform, the female die is arranged on the upper hot forming platform, the sealing cover is arranged on the lower hot forming platform and can cover the female die, and the air supply unit communicates with the sealing cover and supplies air to the sealing cover. The female die is arranged on the upper hot forming platform, the sealing cover is arranged on the lower hot forming platform, the to-be-machined aluminum alloy material is
