And the polishing mechanism is connected with the bearing plate 3, so that the polishing mechanism can be driven to polish burrs on the metal plate in the sliding process of the bearing plate 3. More specifically, after the drilling operation is completed, the power piece 4 drives the bearing plate 3 to drive the drilling piece 5 to slide upwards, and burrs on the metal plate can be polished through the polishing mechanism in the process that the bearing plate 3 slides upwards, so that the metal plate is not required to be detached from the equipment and polished independently, and the efficiency is higher.
The processing frame 2 is provided with the fastener 36 for fixing the metal plate, wherein the fastener 36 can fix the metal plate, so that the stability of the metal plate during drilling operation is improved, the shaking condition of the metal plate is reduced, and the punching operation quality of the punching device is greatly improved. The fastener 36 is connected with the bearing plate 3 through the spreader 17, so that in the use process, along with the sliding of the bearing plate 3, the fastener 36 is conveniently driven to unlock the metal plate through the spreader 17, and the subsequent operation is convenient. Simultaneously, prop out piece 17 and be connected with loading board 3, consequently in the use, need not to set up extra drive unit and order about fastener 36 with sheet metal unblock again, it is more convenient to use, can further play the effect of resources are saved and the energy consumption simultaneously, satisfies work needs.
And the bottom of the processing frame 2 is provided with a transmission piece 35 for transmitting the metal plate, so when in use, when the polishing operation is finished, and after the fastener 36 is unlocked to the metal plate through the supporting piece 17, the metal plate positioned on the processing frame 2 can be driven to slide through the transmission piece 35 at the moment, thereby facilitating the subsequent blanking. More specifically, the transmission member 35 is in transmission connection with the fastener 36 through the transmission mechanism 20, so that in the use process, after the fastener 36 unlocks the metal sheet, the transmission member 35 is driven to move through the transmission mechanism 20, and therefore the metal sheet can be driven to be fed through the transmission member 35, and the use effect is better.
