摘要：
The relationship between the thickness variation of the rolling sheets and the deformation of the rolling for the three-dimensional curved surface parts was analyzed by a curved surface flexible rolling method. The distribution of the uneven roll gap and the function of the working roll arrangement in a convex surface flexible rolling were deduced when the rolls bending shape is the circular. The numerical simulation of the convex surface was applied for the flexible rolling according to the formula. By means of a simple algotithm, the global coordinate reduction has been converted into local coordinate one which led to a better simulation results. A small experimental device was developed and typical test parts were obtained. The simulation and experimental results showed that the curved surface flexible rolling method for three-dimensional curved surface parts is feasible and practical.
