The invention relates to an automatic bending and forming machine tool suitable for metal plates, comprising a base and a side seat. A plate positioning mechanism can be used to position and temporarily store square plates. An electric slide can be used to drive a die to move to a preset position on the upper surface of the square plate through a lifting mechanism, and then an electric suction cup is used to absorb the square plate. After the die is used to move the square plate above two rollers, the die is driven down by the lifting mechanism to be squeezed by the rollers on both sides to complete a primary bending and forming process. After the die is driven to rotate 90 degrees by an electric shaft 2, the die is driven down by the lifting mechanism to complete a secondary bending and forming process. Finally, the die is driven to swing downward by an electric shaft 1, and then the width and height of the die are adjusted to be reduced by telescopic mechanisms 1 and 2. The frame-shaped plate that has been bent and formed is automatically discharged by gravity. The die is easy to demould, and frame-shaped plates of different sizes can be quickly bent and formed. The bending and forming efficiency is high, and the operation is convenient. The plate can also be prevented from being scratched during the forming process.
