    • The sheet metal blanking die (1) comprises a lower part (3), an upper part (5) and guide columns (7) for maintaining the parts (3, 5) aligned These latter present flat parallel mutually opposing horizontal portions (11, 13). The upper part (5) presents a plurality of punches (17) which project downwards from it at the moment of blanking, when the die (1) is closed by the action of a press. Recesses (19) are present on the flat lower portion (13) to receive the respective punches (17) at the moment of blanking. For at least one punch (17) a rapid replacement device can be provided, comprising:
      - in the upper part (5) of the die (1), a chamber (25) within which a loader can move presenting at least two cavities (33) of vertical axis to receive relative punches (17). By moving the loader a punch (39) can be selected for transfer from a rest position, in which it is completely contained within the relative cavity (33), to an operative blanking position in which it is inserted into the punch holder (38);
      - first pneumatic means (65) to facilitate the fall of the punch (39) (by gravity) from the rest position to the operative blanking position;
      - second pneumatic means (67) enabling the punch (17) to be transferred from the operative position to the rest position.
    • 钣金冲裁模具(1)包括下部(3),上部(5)和用于保持对齐的部件(3,5)的引导柱(7)。这些后者存在平行的平行相互相对的水平部分(11, 13)。 上部(5)具有多个冲头(17),当模具(1)通过压力机的作用而关闭时,冲压时刻向下突出。 在平坦的下部(13)上存在凹部(19),以在消隐时接收相应的冲头(17)。 对于至少一个冲头(17),可以提供快速更换装置,其包括: - 在模具(1)的上部(5)中的腔室(25),装载机可移动到其中,呈现至少两个空腔 33)垂直轴接收相对冲头(17)。 通过移动装载机,可以选择一冲头(39)以便将其完全容纳在相对空腔(33)内的静止位置转移到其插入冲头保持架(38)中的可操作的冲裁位置, ; - 第一气动装置(65),以便于冲头(39)(由重力)从静止位置下降到操作消隐位置; - 第二气动装置(67),使得冲头(17)能够从操作位置转移到静止位置。
