Abstract

PURPOSE: To contrive the improvement of piloting characteristic for positioning the material to be blanked, by installing in the upper die a pilot pin for positioning the material, and by enabling the stripper to freely slide against the pilot pin.
CONSTITUTION: The punch plate 3 is fixed to the die set 1 through the spacer 2; the punch 4 and the blanking die 5 are fixed to the punch plate 3. The stripper 6 is placed in the die 5 so as to be freely slidable, and is suspended by the spring 8 through the hanging bolt; the knockout pin 9 is touching the knockout plate. The pilot pin 11, passing through the stripper 6, is set to the punch plate 3 so as to be freely slidable, and is pressed to the punch plate 3 by the spring 12. Since the positioning work is performed under this condition, the straight part 13 of the pilot pin 11 is inserted into the pilot hole of the material at first, and then, the stripper 6 presses the material. As a result, the material and the pilot pin 11 are both prevented from any damage.
