| Zusammenfassung: | A punch mold, comprising a casing (17), a plurality of small diameter and large diameter punches (23) and (27) vertically movably and circularly disposed in the casing, a punch driver (73) vertically movably and relatively rotatably installed on the upper part of the casing, and a striker (87) fitted to the punch driver and capable of pressingly hitting these punches. Stripper springs (51) are installed correspondingly to the small diameter punches, and the large diameter punches are disposed between the small diameter punches. Accordingly, the stripper springs for the small diameter punches on both sides of the large diameter punches act as the stripper springs for the large diameter punches. |
