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.
