DEVICE FOR CUTTING METAL PLATE

The invention relates to a device for cutting a metal plate, and the device is characterized in that the device comprises a pedestal part, wherein the upper surface of the pedestal part is provided with the metal plate; a first frame part which is vertically supported on the upper surface of the pedestal part; and a cutting part which can move along the vertical direction of the first frame part. The cutting part comprises a sawtooth part, wherein the sawtooth part rotates clockwise to cut the metal plate under the condition that a rotating shaft is located at the right side of the metal plate, and rotates anticlockwise to cut the metal plate under the condition that the rotating shaft is located at the left side of the metal plate. The device cannot generate cutting burr on the cutting surface of the metal plate, and does not need to carry out secondary machining.
