Rivet riveting is to use a metal cylinder or metal tube with a diameter slightly smaller than the perforation to pass through the workpiece to be riveted and fix both ends of the rivet.
When the metal column is deformed and thickened due to surface knocking or pressing, rivet heads are formed at both ends, so that the workpiece cannot be separated from the rivet.
Rivet is a nail-like object used to connect two parts (or components), with a through hole at one end and a cap at the other. In riveting, the riveted parts are connected by their own deformation or interference. There are many kinds of rivets, and they are irregular.
Types and uses: commonly used are R-type rivets, fan-shaped rivets, core-pulling rivets (core-pulling rivets), tree-shaped rivets, semi-circular heads, flat heads, semi-hollow rivets, solid rivets, countersunk rivets, core-pulling rivets and hollow rivets, which are usually connected by their own deformation.
Generally, cold riveting is used for those smaller than 8 mm, and hot riveting is used for those larger than this size. But there are exceptions. For example, some nameplates on locks are riveted by the interference of rivets and lock body holes.
