At present, in the riveting of automobile and motor car parts, especially the parts that have vibration and need to move frequently, such as automobile steering gear, ordinary rivets and double-drum rivets are mostly used for riveting. Due to the limitations of the structure of these two products After riveting, the product has the defect of insufficient strength and easy to loosen and fall off, and it cannot be disassembled and can only be used once, thus affecting the quality and performance of the riveted product.

By adopting the above technical solution, the setting of the pin cap allows the user to conveniently drive the pin into the pin hole of the workpiece by using a hammer and other power-assisted equipment. Pin hole, the plane of the top contact body relative to the pin cap will collide with the plane where the pin hole is located, the convex body and the pin hole are tightly squeezed, and the pin cannot fall off.

The core rivet is another type of single-sided riveting. When riveting, the head of the rivet is hit with a hammer to expose the core, so that it is flush with the end face of the nail head, that is, the riveting operation is completed, which is very convenient, especially suitable for inconvenient Riveting occasions using ordinary rivets (which must be riveted from both sides) or blind rivets (lack of a rivet gun). Usually use flat head rivets, countersunk head rivets are suitable for occasions where smooth riveting is required on the surface. Some rivets can also be matched with clothing, becoming a popular element today, mostly the representative of punk style. In addition, there are paired rivets, which are special. Divided into two parts, the thicker section of the rod with a cap has a hole in the center, and the other section of the rod with a cap is an interference fit. When riveting, drive the thin rod into the thick rod.


In the design of modern aviation and aerospace vehicles, in order to reduce weight and save space, the space of the fastening installation system is getting narrower and narrower, and blind hole installation is often required. In this case, single-sided riveting installation is usually used for fastening connection. At present, this kind of fastening connection products are mainly blind rivets. The riveting installation principle of blind rivets is to use the method of pulling, pulling the mandrel, and extruding the nail sleeve to deform it at the blind end to achieve the function of fastened connection. This kind of fastening connection method requires special riveting, generally imported riveting, the replacement of internal parts is expensive, the installation process is complicated, and the installation cost is high.
