摘要： A tooling installation system having unique tools which provide an external force directly to the sleeve end of a faster to create a bulb on the sleeve of the fastener is provided. The system provides external forces directly to the sleeve end of the fastener deforming a portion of the sleeve radially outward and onto the structure prior to swaging a second portion of the sleeve radially inward onto the pin. Additionally, the system controls formation of the sleeve by capturing an external portion of the sleeve creating a cavity between the tool and the structure for achieving proper bulb formation during installation prior to swage. The system also provides specific forces to the head of the pin and the head of the sleeve to insure proper seating of the fastener head against the structure inducing residual compressive stresses within the structure, thus improving mechanical properties such as fatigue life of the structure.

摘要翻译： 提供了一种具有独特工具的工具安装系统，其提供了直接提供到套筒端部的外力，以更快地在紧固件的套筒上产生灯泡。 该系统将紧固件的外力直接提供给紧固件的套筒端部，使套筒的一部分径向向外变形，并将套筒的第二部分径向向内挤压到销上。 此外，该系统通过捕获套筒的外部部分来控制套筒的形成，从而在工具和结构之间形成空腔，以在锻造之前在安装期间实现适当的灯泡形成。 该系统还向销的头部和套筒的头部提供特定的力，以确保紧固件头部适当地抵靠结构，从而导致结构内的残余压缩应力，从而改善机械性能，例如结构的疲劳寿命。
