The rivet nut is a fixing piece which is mainly used for realizing quick installation on one side of a product by utilizing the size of the existing hole site; with the development of automobile light-weight technology, the automobile body is light-weighted by adopting aluminum alloy materials and more nonmetallic parts, so that the weight of the automobile body is reduced, and a better energy-saving and environment-friendly effect is achieved.
At present, aluminum alloy car bodies mostly adopt structures with aluminum alloy profile skeletons combined with skins, wherein the connection modes of the aluminum alloy profiles are mainly welding and riveting. Compared with welding, riveting has the characteristics of simple process, low equipment and tooling fixture cost, difficult deformation of a vehicle body during assembly and the like, so that the aluminum alloy section bar is connected in a riveting mode, and the aluminum alloy section bar is more and more widely applied.
The rivet nut is connected through rivet gun, and is suitable for square pipe, round pipe and other places difficult to rivet. The pneumatic or manual hand riveter can be used for one-time riveting, and is convenient and quick. The conventional rivet nut is mainly used for the connection of non-structural bearing bolts, such as the connection of interior trim parts of railway carriages, highway carriages, ship poises and the like, and the improved rivet nut capable of preventing spin, such as a supporting plate nut for an airplane, is more excellent, and has the advantages of lighter weight, no need of fixing the supporting plate nut by rivets in advance, and no operation space on the back of a base material, and the like.
Therefore, the rivet nut is widely applied, however, at present, waterproof requirements are put forward on rivet connection modes in many fields, for example, in the new energy automobile industry, when the existing rivet nut is used for connection, even if the stability of connection can be ensured, water can infiltrate into equipment along with the rivet nut due to the fact that the rivet nut does not have waterproof effect, and use is affected.
