The invention relates to a simple numerically-controlled bending machine with dual driving systems. The simple numerically-controlled bending machine is provided with a bending plate, two motor driving mechanisms, an electromagnetic clamping device, a bending locating device and a controller, wherein the bending locating device is arranged on the top edge of a workbench and is used for bending locating; the bending plate is movably connected with the top of the workbench by virtue of a hinge; the two motor driving mechanisms are symmetrically arranged on the left and right parts of the lower side of the workbench; each motor driving mechanism comprises a servomotor, a driving worm and two worm wheels, output shafts of the servomotors are fixedly connected with the first worm wheels, the first worm wheels are in driving connection with the driving worms, the driving worms are in driving connection with the second worm wheels, and the second worm wheels are connected with the bending plate and are used for driving the bending plate to overturn and bend; the electromagnetic clamping device is provided with two electromagnetic suction units. According to the simple numerically-controlled bending machine, a hydraulic driving mode and a pneumatic driving mode of an existing numerically-controlled bending machine are replaced by electromagnetic and electric servo driving devices, and the PLC (Programmable Logic Controller) is adopted, so that automatic control is realized, the structure is stable, the processing speed is high, and the cost is relatively low.
