  • Patent number: 8789451
    Abstract: A sheet metal blanking die assembly is described. The assembly has a lower and an upper part and guide columns to maintain the parts aligned during the movement of the upper part relative to the lower part. The upper and lower part present flat parallel mutually opposing horizontal portions. The lower flat portion receives the sheet metal, while the upper flat portion presents a plurality of punches projecting downwards from it when the die assembly is closed by the action of a press. Blanking recesses are present in the flat lower portion to receive the respective punches. The die assembly presents a differential rotation device for a blanking unit positioned to correspond with at least one blanking position.

  • 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.

  • Publication number: 20130233140
    Abstract: A sheet metal blanking die assembly, comprising a lower part, an upper part and guide columns is described. The die assembly upper part and lower part present flat parallel mutually opposing horizontal portions. The lower flat portion is arranged to receive the sheet metal, the upper flat portion presenting a plurality of punches. On the flat lower portion, blanking recesses are present to receive the respective punches and at least one detachment die, below which a brake is present, said brake presenting a through cavity positioned coaxial to that of the detachment die. The brake presents a plurality of contact zones arranged to brake the fall of the individual laminations and possibly to enable the formation of a lamination pack. Means are provided to cool and/or to lubricate just the contact zones between the laminations or the lamination pack and the brake.
