In the invention, by starting a servo motor, not only can the moving plate be driven to move and the automatic feeding effect is achieved, but also the effect of automatically clamping a plate can be achieved through cooperation of a pressing rod and a pressing plate in the feeding process, the automatic discharging effect can be achieved through a rotating block; the automatic metal cutting device is high in automation degree in the whole process and easy to operate; hand pressing feeding does not need to be carried out; labor intensity is low; safety is high; and the cutting efficiency and the cutting precision are greatly improved.
