Abstract
A split die (12) has a removable split die insert (40) to make it adaptable for receiving different types of ferrules. A ferrule (72) and tube (70) to be attached thereto are received into a cavity (42) in insert (40). Tube (70) indexes on a radial shoulder (76) in ferrule (72). A drawbolt (20) with an elastomeric expander (38) thereon is positioned inside tube (70) with its shaft (22) extending outwardly and through an anvil insert (52, 62). The outer end of the expander (38) is prevented from extruding along drawbolt (20) by a split ring (36). The inner end of expander (38) is contained by portions of the anvil insert (52, 62). In one embodiment, shaft (22) extends through a machined bearing surface (56) in insert (52). A boss (54) on insert (52) extends into ferrule (72) and abuts the inner end of expander (38) to contain expander (38). In another embodiment, a plastic sleeve (66) is received into a cavity (64) in anvil insert (62) and provides a bearing engagement with shaft (22) and a sealing engagement with the inner end of expander (38) and adjacent radial end portions of the ferrule (72).
