Abstract：

The origin, research status at home and abroad and application in the manufacturing industry of clinching technology were introduced, and the three basic forms of clinching joints and their characteristics were introduced. Then, the working principle, main working process and issues needed to be paid attention to in each working stage of clinching technology were expounded. Furthermore, by comparing with traditional riveting technology with rivets and resistance spot welding technology, their advantages in reducing process steps, reducing raw material investment, lightweight material connection, improving fatigue strength, energy conservation and emission reduction, safety and environmental protection, and reducing comprehensive cost were deeply analyzed, meanwhile, the shortcomings and future research and development directions of clinching technology in terms of sheet performance requirements, sheet layer amount requirements, sheet thickness requirements, static strength, etc. were pointed out, which provided theoretical reference and selection basis for the independent application of clinching technology in the manufacturing industry of China.
