summarize
Rivet is a common fastener used to connect two parts with a pass hole, usually used for the connection of metal or non-metal materials. A wide variety of rivets, according to different application scenarios and needs, you can choose different types and specifications of rivets. The following will be a detailed introduction from the use characteristics of rivet, rule parameters, quality standards and other aspects.
Use characteristics of rivets
Rivets are widely used in aviation, automotive, construction, electronics and other fields. In automotive manufacturing, rivets are used to connect body structures, such as doors, frames, etc. In the aerospace field, rivets are used for structural connections of aircraft, such as fixed-wing aircraft, rotorcraft, etc. In construction, rivets are used to connect steel structures to building materials. In electronics manufacturing, rivets are used to connect circuit boards and electronic components. In addition, rivets are also used in furniture manufacturing, such as connecting various parts of furniture.
Regular parameters of rivets
The diameter of the rivets is usually 2mm, 3mm, 4mm and other different specifications, and the length can be determined according to the thickness of the material and the needs of the connection. The head shape of the rivet has a variety of options such as flat head, half round head, sink, etc., which can be selected according to different riveting requirements and aesthetic requirements. The material of rivets also has a variety of choices, such as carbon steel, stainless steel, aluminum alloy, etc., to adapt to different use environment and performance requirements.
Quality standard for rivets
The quality standards of rivets include but are not limited to GB/T 876-1986 "Flat head rivets", GB/T 109-1986 "Flat head rivets", GB/T 863.1-1986 "half round head rivets (rough)" and other national standards. These standards specify the requirements of the size, material, surface treatment and other aspects of the rivet to ensure the performance and reliability of the rivet.
Method of testing rivets
The detection methods of rivet include appearance inspection, size measurement, hardness detection, strength detection, etc. The appearance inspection mainly checks whether the rivets have defects such as cracks, burrs, etc. The size measurement mainly checks whether the diameter and length of the rivets meet the standards. Hardness testing and strength testing are through experimental means, such as tensile test, shear test, etc., to assess the mechanical properties of rivet.
As a basic fastener, the design and selection of rivets are crucial to ensure the quality and performance of the product. Understanding the types of rivets, rule parameters and quality standards helps to correctly select and use rivets to ensure the reliability and safety of the connection. When selecting rivets, the application scenario, material requirements and working environment should be fully considered to achieve the best connection effect.
