Abstract
A pull-to-set mandrel riveting tool is provided with mandrel-pulling jaws releasable from mandrel gripping relation, and a pivoted nosepiece assembly including openable rivet abutting means is thereupon movable to carry the mandrel to an out-of-the-way position wherein a rivet to be set can be loaded on the stem of the reusable mandrel. The tool is preferably operable by fluid pressure means, and a stop means is provided for insuring proper longitudinal re-positioning of the mandrel relative to mandrel pulling means. The construction facilitates manual or automatic loading of successive rivets on the mandrel.
Claims8
A pull-through blind riveting tool comprising a housing, a rivet-setting mandrel having a head and a stem and movable toward and from an operating position in the housing, mandrel-pulling means reciprocably mounted in the housing, an assembly for movably supporting the mandrel and including abutment means openable to allow axial passage of a head of a rivet on the mandrel and closeable to abut the rivet head during relative mandrel retraction, and means interconnecting the assembly and the housing permitting their limited relative separation and approach to allow a rivet to be assembled on the mandrel stem when the mandrel head is engaged and positioned by the relatively separated assembly.
A blind riveting tool comprising a housing, an assembly pivotally mounted on the housing and adapted to carry a headed mandrel movably mounted therein while coaxially supporting one or more rivets on a stem of the mandrel, said assembly including abutment means relatively closeable to engage the head of a leading rivet on the mandrel when the latter is aligned with the housing and openable to allow another rivet on the mandrel to pass along the mandrel stem and be engaged by said abutment means when the leading rivet has been set, mechanism including jaws for axially pulling the mandrel through the leading rivet to set it in a workpiece, and means for releasing the mandrel from said jaws.
