GUN RIVET

摘要

The invention relates to a gun rivet and a device for placing said rivet. The gun rivet contains a rivet head with a collar at one end and a rivet tip at the other. The rivet body contains a cavity in the form of a bore in a sleeve section. As with other gun rivets, the gun rivet is shot with a percussive-type action and with the aid of its rivet tip into an opening in two sheets that are to be joined together, until the collar comes to rest on the upper face of the upper sheet. A tensile bolt is then introduced into the cavity and is connected to the base of the latter. This can be achieved by resistance welding. The tensile bolt is then drawn until a rivet head is formed on the opposite side of the two sheets. The tensile bolt is then detached from the gun rivet, for example by shearing. The tensile bolt can be re-used to place another rivet.
