Rivets are produced using automatic riveting machines. Commonly used types include R-type rivets, fan rivets, pop rivets, tree shaped rivets, semi-circular head, flat head, semi hollow rivets, solid rivets, countersunk head rivets, pop rivets, and hollow rivets, which are usually connected to the riveted parts using their own deformation. Generally, cold riveting is used for sizes smaller than 8 millimeters, while hot riveting is used for sizes larger than this.
Blind rivets are a type of rivet used for single-sided riveting, but require the use of a specialized tool - a rivet gun (manual, electric, pneumatic) for riveting. This type of rivet is particularly suitable for riveting situations where it is inconvenient to use ordinary rivets (which require riveting from both sides), so it is widely used in products such as construction, automobiles, ships, airplanes, machinery, electrical appliances, furniture, etc. Among them, open flat round head pop rivets are the most widely used, countersunk pop rivets are suitable for riveting applications that require smoothness, and closed pop rivets are suitable for riveting applications that require higher loads and certain sealing performance.
The process of riveting with a riveting machine includes drilling, deburring, inserting rivets, pressing the top mold against the rivets, and riveting with a rotary riveting machine to form (or manually tightening the pier, thickening the pier, riveting into a cover shape).
