  • Method and a device for reducing the noise level at a deep-drawing press
    Patent number: 7124614
    Abstract: The invention relates to a method and an arrangement in a press tool for reducing the relative speed at which a moveable sheet metal holder impacts against a press upper part for transmitting a working force or is separated therefrom on completion of pressing. The invention is characterised in that the force for acceleration of the sheet metal holder is transmitted from the press upper part by way of a mechanical transmission device fitted to the sheet metal holder in such a way that an initial movement is imparted to the holder before the press upper part comes to bear against the sheet metal fabrication and sheet metal holder, and that only then does the press upper part impact against sheet metal fabrication and sheet metal holder and for depression of gas-filled springs arranged adjacent to and supporting the sheet metal holder.
