Structure Design and Static Strength Analysis of Axial Ring Rolling Machine

The axial ring rolling machine is a special plastic forming equipment especially designed for the complex shaped cross-section ring parts applied in aerospace and aviation. The axial ring rolling process adopted by this equipment is a structural design combining a single cone roller and an annular mold, which can obtain high-precision shaped ring parts by applying axial load to the ring parts and realizing continuous and progressive plastic forming. This paper first analyses the operational characteristics and structural design of the face rolling mill. It then conducts static simulations on key components such as the machine frame, guide columns, tapered roller shafts and pressure roller cages, analysing stress distribution and structural deformation characteristics under high-load conditions, and verifying the service life of the selected tapered roller bearings, in order to validate the correctness and rationality of the face rolling mill’s structural design. The results show that the overall structural strength design of the machine meets the requirements, but under high load, the life of bearings and other components needs to be further improved.
