For the sake of revealing the influence of partial restriction conditions on the thermo-compression deformability of the aluminum alloy ring, this paper adopts the integrated method of numerical modeling and technology to make deep research by taking 7075 aluminum alloy as an example. It turns out that: after being exerted partial restriction, the branch surface will be at the two outside ends during the thermo-compression deformability. Compared with the situation without restriction, after being exerted partial restriction with the protruding model pressure of 8mm, the previous increasing of the internal and external diameter of the ring is changed to the deformability model that the internal diameter decreases and the external diameter increases. Besides, both the internal and external outlines are in the shape of evagination and drum, with the maximum increasing thickness of the side wall from 24.6% to 51.2%. Therefore, restriction imposing can effectively improve the thermo-compression liquidity of the ring, which provides theory basis for the technology preform and deformability liquidity control during the precise formability of the complex components.
