摘要： A punch assembly for a punch press has a punch housing with a punch that is slideably mounted for reciprocation along a punch axis within the punch housing and at least one resilient member in the housing for yieldably biasing the punch upwardly in the housing along the punch axis A punch length adjustment subassembly is provided in the punch housing The subassembly has a base member that is slideable axially but non-rotatably mounted within the housing The subassembly has a punch head that is mounted for rotation on the punch axis relative to the base member but is held against axial movement relative to the base member The invention is also directed to the punch head subassembly per se as a retrofit insert to update existing punch assemblies for manual tooless punch length adjustment and tooless punch removal.

摘要： A punch assembly for a turret-type punch press comprises an outer guide sleeve having an inner bore in which a punch shank fits for reciprocating but not rotating movement. The punch shank has a concentric, downward opening formed in a lower end in which is received a head portion of an insert that has a punch point formed on it. Built into the shank is a latching mechanism for releasably wedging and thereby securing the insert to the lower end of the shank.
