Abstract：

Accuracy of plate bending was directly determined by the position control of bottom rolls and two side-rolls in four-rolls plate bending machine, and the position of rolls which was adjusted by experiences in conventional ways was difficult to obtain the high position precision. The method of mathematical modeling was used to represent the geometric expression of the operative position of rolls and build the bottom roll and two side-rolls model on edge alignment, pre-bending and stretch-bending in plate bending process. Moreover, the formula of accurate displacement of bottom roll and two side-rolls were calculated to achieve accurate control of the operative rolls which enhanced the rolling precision of plate.
