Ring parts like duplicate gear, double-side flange and high pressure value body, are widely used in engineering machinery, which have the common geometrical characteristic of thick-wall, small-hole and deep-groove on the surface. The conventional manufacturing technology for this kind of ring is simple forging with cutting, which has the disadvantageous of high energy and material consumption, low material productivity and poor performance. In this paper, a new manufacturing method for this kind of ring named combined ring rolling (CRR) is firstly proposed based on the minimum resistance principle in metal plastic forming and its forming principle is introduced. Then, the reasonable ranges for key forming parameters of CRR are determined, the FE modeling and simulation analysis and experiment study for the CRR process with a double-side flange ring are performed. By this work, the CRR technique is testified feasible, and the basic thermo-mechanical deformation rules in CRR process are revealed based on simulation with the valid FE model proved by the experiment.
