Abstract:

Rotary forging with multi-cone rolls (MCRs) is a new plastic forming technology. In order to study the process of rotary forging with multi-cone rolls for large diameter thin disc, the finite element model of rotary forging with multi-cone rolls was established, and the forming process of large diameter thin disc parts was analyzed by numerical simulation software Deform-3D. Based on the reliable three-dimensional rigid-plastic FE model, the deformation law of rotary forging with multi-cone for large diameter thin disc part was studied, and the influences of various parameters on the rotary forging with multi-cone rolls were studied. The results show that the equivalent plastic strain distribution on the surface of large diameter thin disc exhibits a water-wave pattern, which extends from the central region to the edge and the whole deformation process is stable. Meanwhile, and the initial temperature of billet, the amount of feeding and the thickness of bottom step have important influences on the rotary forging with multi-cone rolls of large diameter thin disc. The research results promote the further development of rotary forging with multi-cone rolls technology.
