  • Punch assembly with separate adjustable punch guiding shim block
    Patent number: 9186717
    Abstract: A punch assembly for a hydraulic punch press machine that affords the ability to compensate for punch point metal loss due to resharpening by facilitating accurate repositioning of the punch point relative to an aperture in a stripper plate through which the punch point member projects during a stamping stroke of the punch assembly.
    Type: Grant

  • Punch assembly with feed gap maximization
    Patent number: 6895797
    Abstract: A punch assembly for punching or forming sheet metal has a circumferentially extending, horizontally disposed supporting flange that is slideably mounted upon the body of the punch assembly as a part thereof for supporting the punch assembly on a punch press. A resilient tool retractor, e.g., one or more springs is provided within the punch assembly for retracting or elevating the body of punch assembly relative to the supporting flange. Provision is also made for enabling a person to manually change the tool length and thus the feed gap from the exterior of the punch assembly by controlling the distance that the upper forming tool, i.e., the punch extends downwardly below the supporting flange and a lock is provided for securely retaining it in a selected position.
