A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite the head is called the tail. On installation, the rivet is placed in a punched or drilled hole, and the tail is upset or bucked (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. In other … WebRiveting is traditionally part of forging. Forging is a manufacturing process involving the shaping in the thickness of a solid metal billet using localized compressive forces at a temperature below fusion. This subclass subdivides into: Methods. B21J 1/00 - B21J 5/00. Machines. B21J 7/00 - B21J 13/00. Furnaces; Blacksmiths requisites.
