A swage collar and an internal sealing insert form a swage collar assembly used in combination with a structural fastener to prevent leakage through a connection of workpieces fastened together by the structural fastener. The swage collar has a hollow, generally cylindrical main body portion with a main central bore, and a base portion with an internal shoulder formed in the main central bore so as to form a seal receiving guide. The shaft of the fastener typically includes a threaded section and an unthreaded section, and the internal sealing insert interfaces with the threaded section and the unthreaded section of the shaft of the pin. In an alternate embodiment, the internal sealing insert interfaces with the unthreaded section of shaft of the pin. The swage collar assembly is fitted over the fastener, a swaging tool is fitted over the swage collar assembly, and the swaging tool is forced over the swage collar assembly with sufficient force to cause plastic deformation in the swaging collar to force the swaging collar and internal sealing insert into engagement with the shaft of the fastener.

A fastening device for preassembling structural members includes a hollow cylindrical body; a bearing ring provided at a proximal end of the hollow body and against which one of the structural members is intended to bear in a fastening position; a pulling threaded rod extending through the hollow body to be inserted into the structural members; a tightening means connected to the pulling threaded rod for maintaining the structural members against each other, the tightening means including a removable tubular end piece for mounting on a proximal threaded end of the pulling rod that can be locally axially compacted under the action of a force applied on said pulling rod in order to form a radial bead for sandwiching the structural members between the latter and the bearing ring; the fastening device including a sheath.

At least a portion of a first plate and at least a portion of a second plate are arranged to have an overlapping portion, a first deformation unit is formed at the overlapped portion, and a second deformation unit is formed in the first deformation unit. The first deformation unit and the second deformation unit protrude in opposite directions from each other, and the second deformation unit has a smaller cross-sectional width than the first deformation unit. Such a joining structure may be utilized to couple elements together in a display device, such as a plasma display device.

A driving anvil washer retaining apparatus (12) for a rivet gun (14) includes a magnetized element (21). The magnetized element (21) is coupled to the rivet gun (14) and retains an anvil washer (52) during installation of a rivet (82). A method of installing a rivet (82) includes inserting a stem (46) of a rivet assembly (80) into a rivet gun nose (22) having at least one magnetized portion (21). A rivet (82) of the rivet assembly (80) is inserted into at least one object. The stem (46) is removed from the rivet assembly (80). A driving anvil washer (52) is retained via the magnetized portion (21).
摘要:
An armrest attachable to a tool to provide support for a worker's wrist while the tool is being manipulated or actuated. The armrest underlies the worker's forearm so the weight of the tool is borne partly by the worker's fingers and hand and partly by the worker's forearm. Stress on the wrist is minimized and good wrist posture is maintained. Due to the location of the armrest, the worker's forearm is located directly behind the tool handle where it can absorb kickback forces that occur as an incidental part of a lockbolt installation process.
摘要:
A rotatable nose assembly for swaging a fastener collar onto a grooved fastener pin in an application where there is only limited access to the pin and collar assembly. A swaging anvil has parallel flat side faces adapted to fit into a channel-shaped workpiece to facilitate swaging motion of the anvil along the collar surface. The anvil has a rotary swivel connection to the nose assembly such that the flat side faces of the anvil can be rotated to fit different orientations of the channel flanges.
摘要:
A tool for swaging a fastener collar around a grooved fastener pin to secure two or more work pieces together includes an axially elongated anvil and collet that can slide back and forth to perform the swaging operation. Localized side areas of the anvil and collet are cut away to define a clearance space that can fit around projecting portions of the work that might otherwise obstruct the tool against proper placement of the anvil against the fastener collar. The anvil and collet are rotatable as a unit to enable the clearance space to be oriented at any desired location around the anvil circumference.
