摘要： A friction stir rivet is rotated in a precessing motion and driven through a first fusible workpiece into an engaged second fusible workpiece, causing local portions of the first and second workpieces to plasticize. When the rivet is driven through the first workpiece and into the second workpiece, rotation is stopped and the plasticized material solidifies around the rivet creating an enlarged weld joining the metal workpiece and encompassing the rivet, which provides additional mechanical strength.

摘要： Mechanical and adhesive charged blind fasteners have an annular one way flat or O-ring seal mounted at one end of a cylindrical rivet body sealingly engaged with an axially extending mandrel stem to provide a torodial chamber. The body has radial adhesive-extruding openings therethrough around which a vacuum may be established for initial adhesive charging purposes. For charging, the seal is deflected by the force of a flow of adhesive from a supply responding to the establishment of a positive pressure differential between the supply and the exterior of the body. With the torodial chamber opened, viscous adhesive readily flows therein from the supply. After being filled, the vacuum is terminated and the seal naturally recovers and closes the body to confine the adhesive therein. Adhesive charging can be achieved by other mechanisms that impress a load on the supply to effect seal opening.
摘要翻译：机械和粘合带电的盲紧固件具有安装在圆柱形铆钉体的一端处的环形单向平面或O形环密封件，该圆柱形铆钉体与轴向延伸的芯棒轴密封地接合以提供旋转室。主体具有径向的粘合剂挤压开口，围绕该开口可以建立用于初始粘合剂填充目的的真空。为了充电，密封件通过来自供应源的粘合剂流的力而被偏转，响应于在主体的供应和外部之间建立正压差。在开启室内时，粘性粘合剂很容易从电源中流出。填充后，真空终止，密封件自然地回收并封闭主体以将粘合剂限制在其中。粘合剂填充可以通过其他机构来实现，这些机构使电源上的负载受到影响，以实现密封开口。

摘要： A first metal member is contacted with a second metal member. A metal fastener is provided including a core and a cladding disposed upon the core. The fastener is driven through the first member and into the second member, inducing friction between the fastener, the first member and the second member for at least locally melting portions of the cladding, the first member and the second member to form a flowable material that solidifies and metallurgically bonds the fastener to the first member and the second member for attaching the members together.

摘要： A friction stir rivet is rotated and driven through a first fusible workpiece into an engaged second fusible workpiece, causing local portions of the first and second workpieces to plasticize. A slideable cap contacts the exposed surface of the first workpiece shortly after the process begins. The cap acts as a retaining element limiting plasticized material from escaping during the process. As the rivet is further driven into the members the cap slides up the rivet and actuates an angled stirring member to increase the stir radius around the body of the rivet. Once the rivet is driven into the first and second workpieces, rotation is stopped and the plasticized material cools and hardens around the rivet, creating a weld joining the workpieces and encompassing the rivet, which provides additional mechanical strength.

摘要： A method and apparatus are provided for loosely attaching blind rivets to components of an assembly. The method includes attaching a rivet to an assembly while positioning the head at a predetermined clearance away from the adjacent one of the assembly components. One or both of the aligned openings in the components may be enlarged to leave radial clearance between the assembled rivet body and the enlarged openings. The apparatus includes a nose insert for use with or attachment to a rivet gun or attaching apparatus. The insert forms a stop engageable by a preformed rivet head to maintain a predetermined clearance between the rivet head and adjacent component when the rivet is attached to components forming an assembly.

摘要： The present disclosure relates a rivet body, including a rivet head and a rivet shank, composed of a different material than a mandrel used for insertion into a workpiece(s), the mandrel including a mandrel shaft and a mandrel cap. The rivet body receives the mandrel shaft, including the mandrel cap, through the rivet shank. The mandrel shaft is received by the installation tool, which rotates the rivet body, and the mandrel cap locally deforms workpieces(s) through friction riveting to install the rivet body. During the friction riveting, the fast-rotating rivet body is pushed into the workpiece(s) causing local deformation/melting where the mandrel cap contacts the workpiece(s). The mandrel cap creates a cavity which progresses through an upper surface and a lower surface of the workpiece(s).
