Abstract

The invention relates to the technical field of special forming manufacturing processes of complex thin-walled aluminum-lithium alloy structural parts, in particular to an ultralow-temperature flexible forming device for the complex thin-walled aluminum-lithium alloy structural part. The thin wall refers to that the wall thickness of the structural part is not larger than 5 mm, and the complex structural part refers to that the shape of the structural part is of spatial curved surface structure. The ultralow-temperature flexible forming device is particularly suitable for forming the thin-walled complex aluminum-lithium alloy structural part. By utilizing the characteristics of plastification and reinforcement of the aluminum-lithium alloy at ultralow temperature, an ultralow-temperature flexible forming method is adopted to conduct flexible formation of an aluminum-lithium alloy plate, and then the problems that when indoor-temperature formation is conducted on the complex thin-walled aluminum-lithium alloy structural part, a complex-shaped component is difficult to form, fracture toughness is poor, defects such as microcracks are prone to generation during indoor-temperature forming, the forming resilience is large, and the shape and size precision of the component is difficult to guarantee are solved.
