Core pulling riveting head is a riveting connection head, suitable for application in the absence of open or closed components. The closed part refers to the critical top that cannot be reached at the distal end of the riveting equipment. When selecting this type of connection, there is no need to design a process safety channel for riveting equipment, and one side riveting can be carried out. Therefore, it can make the overall design of the product more compact, further reducing the volume and net weight of the product variety. Blind bolts include open type blind bolts, closed type blind bolts, single drum brake blind bolts, multi drum blind bolts, inner locking wire bolts, and outer locking wire bolts,Multi-grip RivetFumeilai Nail, Little Lantern Bolt, etc.

The core pulling riveting head is named after the bolt forming method. In riveting equipment, the shaft neck is removed and a pull rivet is produced on the far side of the riveting side, that is, the bolt produces the head of the head.

Compared with solid core bolts, rivet heads have the following advantages:

1) The clamping force of the connection is more uniform, thereby improving the fatigue limit of the connection.

2) When riveting, it does not cause impact force and can rivet some raw materials that are easily damaged by impact (such as plastics and carbon fiber materials, polymer materials).Double drum rivets for automobilesThe impact of solid core bolts not only damages the edges of the bolt holes, but also causes loosening in the middle of the polymer material layer plywood, reducing the compressive strength of the raw materials.
