Efficient full-automatic bending machine for G-shaped edge beam

The efficient full-automatic bending machine comprises a supporting table, an n-shaped plate is installed at the lower end of a lifting mechanism, the lifting mechanism controls the n-shaped plate to move downwards, the n-shaped plate conducts first-step bending on a plate, a roller makes contact with the plate, scratches can be prevented from occurring on the surface of the plate, and the attractiveness of the plate is improved. A first template is arranged in the middle of the upper surface of the supporting table, a second template is inserted into the first template, the first template and the second template support a plate, and before the plate is placed on the surfaces of the first template and the second template, the first template and the second template are controlled to be separated by a certain distance through a third electric cylinder, so that the plate can be conveniently and rapidly taken down subsequently; and a driving mechanism is installed in the middle of the right side of the upper surf
