Abstract：

The basic structure and work principle of the four-roll plate bending machine were introduced and according to the two situations which the working rollers arranged symmetrical and asymmetrical, the force of the four-roll plate bending machine was analyzed. Based on the analysis of the need of the maximum deformation moment and the force of the rollers, considering the function conversion principle, the relationship between the force，the moment and the drive power of the equipment was established and a method of calculation of the drive power of main drive system of the four-roll plate bending machine was obtained. The result of the calculation was regarded as the basis to select the main motor power. The result was proved effectively by an actual example.
