This study investigates the double-roll rotary forging technology of large-diameter thin-walled discs by establishing a 3D finite element model. The distribution of stress field and velocity field, as well as the impact of die preheating and initial workpiece size on uniformity and maximum axial load, were studied.
Double-roll rotary forging is an advanced partial progressive forming technology with multi-factor coupling interactive effects. To date, a few relevant researches on the double-roll rotary forging technology of large-diameter thin-walled discs have been reported, and the stable rolling conditions, stress field, velocity field, and so on are not studied in detail. Herein, a reasonable 3D rigid-plastic finite model of the double-roll hot rotary forging of a disk workpiece is established under the DEFORM software environment. Based on the valid 3D finite model, the distribution of stress field and velocity field and the influence of die preheating and initial size of workpiece on the uniformity and maximum axial load were studied. The research results can promote the application and development of rotary forging technology.
