초록정보

The study is concerned with the basic design of horizontal ring-rolling machine and an analysis of profile ring-rolling of L-section. A method of analysis is proposed for the profile ring-rolling of L-section. A kinematically adimissible velocity field is derived by assuming an adequate plastic region in the normal range of operation. The upper-bound method is then applied to determine the roll torque of the driven roll. The roll torques are calculated for some process variables. Experiments are carried out for annealed aluminum alloy(Al 2014) at the elevated temperature. The roll torques are measured with respect to ring thickness variation and various feed rates. The experimental results are then compared with the theoretical calculations. Both the experiments and the theoretical calculations show that the torque has a maximum at the moment the rib is constrained by the roll surface and torque decteases afterwards. The comparison also shows that the experimental observation is in reasonably good agreement with the theoretical prediction.
