  • Patent number: 8739668
    Abstract: A sheet metal blanking die has a lower and an upper part and guide columns for maintaining the parts aligned. The upper part presents a plurality of punches which project downwards from it, when the die is closed by a press. Recesses are present on the flat lower portion to receive the respective punches at the moment of blanking. For one punch a rapid replacement device can be provided, including a chamber within which a loader can move presenting two cavities of vertical axis to receive relative punches. By moving the loader a punch can be selected for transfer from a rest position to an operative blanking position.
