The Principle and Design Method for Ring Rolling

The deformation characteristics of ring rolling are analysed. The mechanical models for biting, p.lastic penetration and bending in ring rolling are presented and the criteria for biting, plastic penetration and rigidity in ring rolling are established and the principle of ring rolling is explained systematically. Technological design method for ring rolling is developed on the basis of the principle of ring rolling and calculating formulae for pre form, Groove and feeding parameters are derived. The criteria for biting and plastic penetration are verified according to ring rolling experimental results.
