ADAPTER, METHOD FOR PUNCHING POLYGONAL HOLES AND METHOD FOR FIXING BLIND RIVET NUTS OR BLIND RIVET STUDS, USING AN ADAPTER OF THIS TYPE

摘要

The invention relates to an adapter (1) for punching polygonal holes using a tool ram (2). Said ram can be displaced and has a punching section (27) that is radially spring-loaded. The adapter comprises a locking device (4) for preventing the radial spring-loaded displacement of the punching section (27) at least during the punching process and an adapter connector (21) for detachably coupling the mandrel (36) of a riveting device (34) to the tool ram (2) at the same time as the locking device (4) is actuated. The invention also relates to a tool unit, to a method for punching polygonal holes and to a method for fixing blind rivet nuts and/or blind rivet studs.
