Abstract
PURPOSE:To part and blank a scrap without any sag on a cut surface by providing a cutting edge for the work and a plurality of parting edges extending from the cutting edge on a die and the cutting edge for the work only on a punch. CONSTITUTION:The work W is put on the punch 6 and the die 1 is lowered. First, a plurality of parting pieces 5 extending radially on the die 1 come into forced contact with the work W and the work is parted by a parting edge line 5a and cut by a cutting edge line 5b for the internal circumference along a line (a). At this time, the punch 6 acts as a supporter of the work. When the cutting edge line 5b for the internal circumference is cut, this edge line 5b cooperates with the work cutting edge 7 of the punch 6 to shear the work along a line (a). By the lowering of the die 1, the work cutting edge 7 of the die 1 and the work cutting edge 7 of the punch 6 continue shearing operation, a product (p) and a scrap (s) are isolated and removed easily from the die.
