Abstract (en)

[origin: EP3769859A1] A metal joining apparatus (31) is provided. In another aspect, a single piece die guard (51) includes an integral die shield section (71) and an integral retainer section (73) wherein a die anvil (161, 461, 561) can be removed. A further aspect employs a workpiece-facing surface of a die guard having a generally uniform height at both a die shield section and a retainer section with a separately insertable anvil and/or die body (163). A method of assembling a die assembly includes inserting a die blade (121, 321, 421, 521) sub-assembly into one end of a bore of a die guard, and inserting at least a portion of a die having an anvil into an opposite end of the same bore in the die guard. Yet another aspect discloses an apparatus and a method of assembling a die assembly wherein a laterally enlarged flange (167, 467, 567) of a die is removeably trapped between a backside of a die guard and an actuator frame (33) to which the die guard is removeably secured, with a workpiece-clinching anvil projecting from the die within the die guard.
