If you want to use the blind rivets better,you should learn more about the working principle of blind rivets.
Blind rivets are an important tool for riveting. Riveting generally requires double-sided operation. The emergence of blind rivets makes single-sided operation a more convenient and feasible process, no noise, no damage to the workpiece, light work, convenient, and sanitary; labor-saving, time-saving, labor-saving, accurate and strong; widely used in products such as construction, automobiles, ships, airplanes, machines, electrical appliances, and furniture.
The working principle of blind rivets is realized by pulling the core head. The rivet is a hollow rivet with a mandrel in the center. The end of the mandrel is round neck shape. When operating, first drill the rivet hole with an air drill or an electric drill and insert the rivet. , Use the chuck of a manual rivet gun or a pneumatic rivet gun to cover the rivet core, and apply a pulling force to bite the rivet core. The pressure on the rivet head will force the softer rivet head to expand into a flange shape. Make the materials tightly combined, and then apply tension again until the mandrel is broken, and the plates can be riveted.
Analysis of specifications and types:
According to different materials, blind rivets can be divided into aluminum alloy blind rivets, iron and stainless steel rivets.
According to the different head shapes of blind rivets, rivets can be divided into round head and countersunk blind rivets; the selection of blind rivets is before the usage of blind rivet guns to riveting the workpiece, so choose the appropriate blind rivets are very important.
The selection of blind rivets usually follows the following principles: general material joints use aluminum alloy round head blind rivets; use the same material according to the workpiece material; use countersunk blind rivets when the workpiece surface is required to be smooth; when it contains acid and other corrosion, use stainless steel rivets for places with sexual substances; choose appropriate rivets for the diameter, length and thickness of the rivet in turn; the diameter of the material is larger than the diameter of the rivet by about 0.1mm; ordinary blind riveting is to insert the rivet from one side of the plate. And it must be topped with a top iron pad, and then riveted with a riveting tool (may be a riveting nut gun, or a pressure riveting tool, etc.), but when using a rivet gun, only one side operation is required to complete the work. Use a rivet gun Carry out riveting operations.
