Definitions

  • the utility model belongs to the technical field of riveting connection, and particularly relates to a novel electric servo magazine type self-piercing connection system.
  • Riveting technology is a joining technology of metal materials. It applies the theories of elastic deformation and plastic deformation, and combines the processing characteristics of extrusion, stamping, rolling and other process characteristics with a small energy loss. It is a processing method that uses The punch completes the connection of difficult-to-weld metals. The punch is used to punch the sheet metal, which causes the sheet metal to produce strong plastic deformation and connect the sheet metal together. Riveting has a wide range of applications and can connect parts that are difficult to be welded. At present, some automotive companies in Europe and the United States use pressure riveting technology for all-aluminum bodies. As the connection theory and practice mature, it will be widely used in the aerospace field.
