The invention relates to a charge bar cutting device with discharging function. The device comprises a device head, a supporting frame and a base plate, wherein the supporting frame is vertically mounted at the rear end part of the base plate; the device head in which a cylinder is mounted is arranged on the top part of the supporting frame; a piston rod end of the cylinder is connected to a cutter, and an edge of the cutter is downwards arranged; a workpiece fixing seat is mounted on the base plate corresponding to the cutter; a workpiece positioning hole is formed in the workpiece fixing seat; discharging plates are mounted at the left side and the right side of the base in a sliding manner. According to the device, a charge bar of the workpiece can be quickly cut through the cutter, andthe workpiece can be pushed into a hopper through the discharging plates, so that the purpose of semiautomatic operation is achieved. The device is simple in structure, and scientific and reasonablein design; the notches of the charge bar of the workpiece are uniform and high in consistency, so that the working efficiency is improved; the labor cost is decreased; and moreover, the product quality is effectively improved.
