Ring rolling is also called ring rolling or reaming. It uses ring rolling equipment-ring rolling machine (also called rolling and expanding machine or reaming machine) to reduce wall thickness, expand diameter, and Plastic processing technology for profile shaping.
Ring rolling is a continuous partial plastic forming process. Compared with the overall die forging process, it has significant technical and economic advantages such as greatly reduced equipment tonnage and investment, less vibration and impact, energy saving and material saving, and low production costs.
Widely used in machinery, automobiles, trains, ships, aviation, aerospace, petrochemical, nuclear energy industry and other fields
Features:
(1) The diameter of the driving roller and the core roller are very different;
(2) The rotation speed of the driving roller and the core roller are different;
(3) Rotary rolling motion and linear feed motion are independent of each other;
(4) The radial rolling motion and the axial rolling motion of the end face are mutually restricted, and both are restricted and interfered by the guiding motion;
(5) During rolling, the ring-shaped blank repeatedly passes through the rolling profile with gradually decreasing height;
(6) The geometric boundary of the deformation zone of the ring is complex and unstable, and the thermal and force conditions of deformation are also dynamically changing.
