[0028] A second cylinder 406 is provided on one side of the discharge box 403, and a second piston rod 407 is movably inserted into the action end of the second cylinder 406, and one end of the second piston rod 407 extends into the discharge chamber 404, and the second piston rod 407 is used to push the bar material in the discharge chamber 404 to the clamping position of the pneumatic chuck 3 when the first cylinder 402 is at the end of the stroke; when working, the bar material is first placed in the vibration plate in the feeding mechanism 2, and the vibration plate works to transport the bar material to the feeding track 202. The vibration plate will generate large noise and vibration during operation, affecting the working environment and machine tool accuracy. The sound insulation cover 201 on the outside of the vibration plate isolates the noise and effectively reduces noise pollution; the bar material moves to the exit of the feeding track 202. At this time, when the first cylinder 402 is at the beginning of the stroke, the discharge chamber 404 on the discharge box 403 is opposite to the entrance of the feeding track 202, and the bar material enters the discharge chamber 404, and then the first cylinder 402 is started , the first piston rod 405 extends and becomes longer, pushing the first cylinder 402 downward in the opposite direction, and the first cylinder 402 drives the discharge box 403 and the bar material to move downward, and moves the discharge box 403 to the pneumatic chuck 3.
