With the increasingly fierce market competition in the machinery manufacturing industry, automobile enterprises continue to release new cars to the sales market. In addition to highlighting the characteristics of high cost performance, low price, new style and function, the key market competition is focused on the rationality of car driving. In the past 20 years, car manufacturers have been looking for ways to solve the difficulties. Tests have proved that it is feasible to use new materials and lightweight raw materials to achieve the lightweight of car body and improve the rationality of car driving. Many characteristics of the car can be improved and enlarged according to the reduction of the whole vehicle quality. The research shows that when the quality waterproof lantern rivet of the whole vehicle is reduced by 10%, the rationality of gasoline and diesel oil is increased by 3.8%, the acceleration time is reduced by 8%, the CO emission is reduced by 4.5%, the braking distance is reduced by 5%, the tire life is increased by 7%, and the conversion force is reduced by 6%. The key development potential of automotive new energy is the application of many non-ferrous and non-metallic materials in the production and manufacturing of car body, such as aluminum, aluminum alloy profiles, die-casting aluminum and its reinforced plastic stool plate. So far, resistance spot welding is the key way to connect the structure of heavy steel car body However, for the connection between light metals and rare metals, the connection between the vast majority of rare metals (such as thin aluminum alloy plate), the connection between metal materials and non-metallic materials of automobile rivet manufacturers, the connection between non-metallic materials, and the connection between light metals with poor malleability, pre painted or coated light metals, can be used for the connection between light metals and rare metals, Welding is very difficult or helpless, so it is clearly proposed to choose riveting technology to connect the inner and outer covering parts of the car body instead of welding. The full-automatic riveting technology comes into being.
