| 20090314150 | DIE FOR COOPERATING WITH A PUNCH - A die cooperates with a punch to pierce a blank, and includes a hollow die body and at least one limiting unit. The die body has a top surface adapted to support the blank, a bottom surface, and a through hole extending through the top and bottom surfaces. The through hole is adapted to permit a scrap from the blank to move therethrough. The limiting unit has a limit component which is disposed in the die body below the top surface. The limit component is resiliently movable between a non-limit position where the scrap is permitted to pass through the limit component when being pushed downward by the punch, and a limit position, where the scrap is limited from moving upward when the punch is pulled upward. | 12-24-2009 |
