Rivets usually consist of a head and a stem. The stem is inserted into the small hole of the metal plate, and the head is exposed on the surface of the metal plate. By hitting the head, the stem of the rivet will be deformed, thus firmly connecting the two metal plates together. Rivets come in various shapes and sizes and can be selected according to different applications and materials.
The main function of rivets is to connect metal plates into a whole and form a more complex structure. Rivets are widely used for fixing and connecting various metal parts in the fields of airplanes, vehicles and buildings. By using rivets, different metal plates or metal parts can be firmly connected together, thus improving the strength and stability of the whole structure.
The application history of rivets can be traced back to ancient times. As early as ancient Rome, people began to use rivets to fix wood and stone buildings. With the development of industry and technology, the manufacture and design of rivets are constantly improved and perfected to improve their strength, durability and applicability.
Development history of rivets;
The earliest rivets are small pegs made of wood or bone, and the earliest metal deformation may be the ancestors of rivets as we know them. There is no doubt that they are the oldest known metal connection methods, which can be traced back to the initial use of malleable metals.
For example, in the Bronze Age, the Egyptians riveted six wooden fans on the outer line of the grooved wheel with rivets. After the Greeks successfully cast large statues in bronze, they riveted the parts together with rivets.
19 16, when H. V. White of British Aircraft Manufacturing Company first obtained the patent of blind rivet that can be riveted on one side, people hardly expected that this kind of rivet would be so widely used. From aerospace to office machines, electronic products and playground equipment, it can be said that this blind rivet has become an effective and stable mechanical connection method.
It is not clear when the blind rivet was invented, but the harness was invented in the 9th century or10th century. Rivet harness, like a horseshoe with nails, liberated slaves from heavy labor. Rivets also led to many important inventions, such as iron pliers and wool scissors for copper and iron workers.
