In actual operation, the blanking mechanism 7 comprises a blanking cutter 10 capable of vertically lifting, when the die is closed and is located at a linkage station corresponding to the transmission block 16, the die pushes the blanking cutter 10 through the transmission block 16 to cut off an area between adjacent workpieces, so that the workpieces are separated from the raw material plate. The vertical projection of the blanking cutter 10 completely covers the connecting part, so that the connecting part can be completely cut, and the workpiece has a flat end edge.
In actual operation, the inlet of processing passageway 3 is equipped with punching mechanism 11, punching mechanism 11 includes the drift 12 with the linkage that opens and shuts of mould, and when the former plate equidistance was stepped on, drift 12 opened and shut along with the mould and carries out the punching operation at the former plate to punch the through-hole 13 that the equidistance was put apart on the former plate. As the punch 12 is fixedly connected with the die, the punch 12 is matched and linked with the die, and the through holes 13 which are arranged at equal intervals can be obtained on the raw material plate.
