The invention discloses an aluminum-based composite material multi-direction double-level deformation restraining device and an application method thereof, particularly relates to an aluminum-based composite material multi-direction double-level deformation restraining device and an application method thereof, and aims at solving the problem that according to a traditional aluminum-based compositematerial extrusion forming method, material diameter-direction size increasing is hard to achieve. The aluminum-based composite material multi-direction double-level deformation restraining device iscomposed of a lower pressing head, an upper pressing head and an annular restraint die. The method comprises the steps that firstly, a cylindrical blank and a cylinder annular wrapping sleeve material which are the same in height are prepared and are in interference fit, and blank preparing is finished; secondly, preheating is conducted, the blank, the upper pressing head, the lower pressing head, a heat preservation bottom plate and the annular restraint die are preheated to the assigned temperature; thirdly, the heat preservation bottom plate, the lower pressing head, the blank and the upper pressing head are placed on a press machine platform; fourthly, the press machine is controlled, and the blank is compressed and deformed; and fifthly, heat treatment is conducted. According to thealuminum-based composite material multi-direction double-level deformation restraining device and the application method thereof, after multi-direction double-level deformation restraining, the comprehensive performance of a composite material can be effectively improved, and the composite material radial size is increased by 15%-25%. The aluminum-based composite material multi-direction double-level deformation restraining device and the application method thereof are used in the aerospace industry.
