“…main roll and mandrel). In order to roll profile rings shaped on upper or lower surface, the idea using partial continuous extrusion of the profile axial conical rolls were put forward (Jenkouk et al, 2013;Li et al, 2012Li et al, , 2014aZhou et al, 2014), as shown in Figure 9. This technique further expands the shape of profile rings rolled by RARR.…”

Rings are basic mechanical components. Ring rolling is a well-known advanced plastic forming technique to manufacture high-performance seamless rings. Since the 21st century, the fast development of global manufacturing has raised an urgent request to high-performance rings, thus, comprehensive and in-depth studies on ring rolling technique were carried out. Based on long-term investigations and attentions on ring rolling, important developments of ring rolling theory and technique in recent 15 years were simply summarised, including the traditional radial ring rolling and radial-axial ring rolling, as well as the novel combined ring rolling. It is expected to give a valuable reference to the research and application of ring rolling.Keywords: ring rolling; theory; technology; equipment; recent development.Reference to this paper should be made as follows: Hua, L., Deng, J. and Qian, D.

“…As the size of the large diameter and thinwalled metal discs workpiece increases, the huge forging tonnage makes it impossible to manufacture the large diameter and thin-walled metal discs by forging. Hot rolling technology can reduce forming load and manufacture thin-walled metal plates [4][5][6]. However, the formed shapes of hot rolling require extensive machining to produce the final disc workpiece, this disrupts the metal flow and affects the performance of the disc workpiece.…”

Double-roll rotary forging is an emerging plastic forming technology based on rotary forging. Owing to the advantages of being labor-saving, a small eccentric load, low noise and vibration, good uniformity, high surface quality, and material saving, it is very promising for the fabrication of large diameter thin-walled disks. To date, little relevant research on the double-roll rotary forging technology of large diameter thin-walled metal disks has been reported, and the deformation characteristic and the influence of three key parameters on the double-roll rotary forging process remain uninvestigated. Herein, a reasonable 3D rigid-plastic numerical model of the double-roll rotary forging of a disk workpiece is established under the Deform software environment. Based on the valid 3D numerical model, the deformation mechanism, and the effective laws of three key parameters (feed rate v of the lower die, rotational speed n of the upper die, and the initial temperature T of the disk workpiece) on the metal flow and force and power parameters in the double-roll rotary forging process have been explored. The research results provide valuable guidelines for a better understanding of double-roll rotary forging for the fabrication of large diameter thin-walled disks.

“…Han et al [7] Metals 2020, 10, 979 2 of 13 simulated plastic deformation behaviors and mechanical properties of the rolling ring by using a new combined radial and axial ring-rolling process. By using DEFORM finite element analysis software, Zhou et al [8] proposed a 3D thermomechanically coupled rigid-plastic finite-element model to analyze the effective strain distribution of large L-section rings. Li et al [9] found that the inhomogeneous deformation degree of double-groove ball-section cold-rolling rings varied with the increasing of roll ratio by ABAQUS/Explicit software.…”

Aerospace thin-walled rings are vulnerable to machining distortion during the manufacturing process. Various research results show that the main factor causing machining deformation is initial residual stress inside the blank. In this study, the residual stress of a 2219 aluminum alloy ultra-large rolling ring was measured by using the indentation strain-gauge method. Results showed the maximum residual maximum principal stress was +265 MPa and stress distribution was uneven. To homogenize the initial residual stress of the ring, an expansion method is proposed based on the principle of pre-stretching plate, and the feasibility of the expansion method was analyzed by establishing a simplified theoretical model of ring. A FE (Finite Element) model was established to investigate residual-stress evolution during the rolling ring and the expanding ring process. The expansion simulation results show that the reduction rates of residual stress were greater than 40% and the maximum residual stress was only 65 MPa.
