APPARATUS FOR SWAGING FERRULES

Apparatus for swaging a ferrule or ferrules onto an outer wall of a cylindrical member includes a hydraulic power section and an adapter tool. The hydraulic section is disposed within a housing, and the adapter tool is at least partly retained in the housing and also is fully removable from the housing without affecting the hydraulic power section of the apparatus. The hydraulic section includes a piston that is moved under force of hydraulic pressure applied thereto from a hydraulic pressure source. The adapter tool includes a driven swaging die that is moved from a retracted position to an extended position in response to movement of the piston. The sleeve and anvil are releasably secured together so that the adapter tool can be removed from the housing as a unitary assembly. Size changes can be accommodated by removing a first adapter tool of a given size and replacing it with a second adapter tool of a different size. This changeover can be implemented without any disassembly or compromise of the hydraulic section. The apparatus also provide a visual indication that a swaging operation is completed by action of an indicator knob that axially pops out of the back end of the housing at the end of a swaging operation.
