摘要: An anvil for a blind riveting tool for locking the plugs of self-plugging blind rivets. The anvil has a central aperture (11), an annular abutment face (13) peripherally of the aperture (11) and a rim (14) radially inwardly of the abutment face (13) and peripherally of the aperture (11). The rim (14) projects forwardly of the abutment face (13) and has a forward end face (16) which is inclined rearwardly and outwardly and provided with generally concave recesses (15) which extend radially across the end face (16) and divide it into a plurality of lands (20) which during placing of a rivet operate to swage part of the mandrel of the rivet into locking engagement with the shell of the rivet.

摘要: A blind rivet for fastening apertured sheets comprises a tubular shell having a head at one end, and a mandrel having an enlarged head which when pulled into the bore of the shell deforms the shell to produce a blind head. The mandrel has a breaker groove at which it breaks when the rivet is fully placed, leaving the mandrel head plugging the shell. The mandrel head has an integral peripheral skirt which can be deformed outwardly by a tool used for placing the rivet, so that the skirt engages the shell and prevents the mandrel head from being pushed out of the bore of the shell. The mandrel head is adapted to wiredraw after the blind head has been formed so that the mandrel will break substantially flush with the head of the shell when fastening either thick or thin sheets.

摘要: In a blind self-plugging rivet of resilient nylon-66 material the stem head has an annular projecting barb adjacent the breakneck, and the shell has a short counterbore at its head end into which the barb expands, when the stem head is fully pulled into the shell, to assist in locking the stem head in the shell. At its tail end the shell bore has a plurality of annular faces arranged step-wise, to engage behind the end face of the stem head over a range of possible positions of the latter depending on the thickness of the riveted members.
