Abstract

PURPOSE: To prevent the punch of ring shape from being deformed by providing the lower die knockout incorporating the knockout-pin for the punched layer inside the punch of ring shape of the lower die and discharging the punched scrap at every punching time.
CONSTITUTION: The material 8 is mounted horizontally between the upper die 1 and the lower die 2, by lowering the upper die 1 and pressing the stripper plate 7 down, the material 8 is punched in the ring shape at between the male die cutting blade 6b of the punch 6 of ring shape and the female die cutting blade 5a of the outer shape punching die 5, and at between the female die cutting blade 6a and the male die cutting blade 3a of the inner shape punching punch 3. Next, when the upper die 1 is elevated, because the knockout pin 12 is energized with the spring 12c, so its top end 12a projects from the upper end 11a of the lower die knockout 11, the punched scrap 10 in the punch 6 is pushed out from the lower die 2. Further, when the upper end of the products knockout 4 of the upper die 1 is knocked, the ring shaped products 9 is pushed to between the upper die 1 and the lower die, and is blown out from the die together with the punched scrap 10 by the air flow. Therefore, no punched scrap fills the ring shaped punch 6 during the punching time.
