摘要:
Die Erfindung bezieht sich auf ein Nietsetzgerät mit einer Nietsetzeinrichtung und einem die Nietsetzeinrichtung betätigenden Antrieb und einer Magazinstreifenzugeinrichtung, die eine mit dem Antrieb wirkverbundene Rolle aufweist. Um deratige Nietsetzgeräte auch pneumatisch und / oder hydraulisch betreiben zu können, ist erfindungsgemäß vorgesehen, daß der Antrieb einen pneumatischen und / oder hydraulischen Linearantrieb mit einer Kolben-Zylinder-Einrichtung aufweist und ein Getriebe vorgesehen ist, das eine Linearbewegung der Kolben-Zylinder-Einrichtung zumindest zeitweise in eine Drehbewegung der Rolle übersetzt.
摘要:
A fastening machine (e.g. for rivets) has a fastening head (20) where the fasteners (30) are brought into alignment with the punch (22) and die in a carrier tape (10). The carrier tape (10) has a web (11) with slots (15, 16) or teeth engageable by a sprocket wheel (27) which sequentially advances the fasteners (30) until the stems (31) engage a retractable stop (32). When the punch (22) is advanced, the fasteners (30) are pushed through the carrier tape (10) to be deformed by an upsetting die aligned with the punch (22). In modified embodiments, the fasteners (30) are urged transversely from the web of the carrier tape, the carrier tape being advanced by a gear which engages teeth on a side flange on the carrier tape. The sprocket wheel (27) may be remotely driven e.g. by a flexible cable drive to accommodate the movement as the fastening head (20) is advanced towards, or retracted from, the upsetting die.

A fastener carrier tape (1), for fasteners (4), such as rivets, with a shank (15) and relatively enlarged head (16), incorporates successive fastener retention apertures (5) with supplemental peripheral weakening slits or cut-outs (6), to promote controlled tape deformation and failure and thus controlled discharge of the fastener head through the tape and retain fastener orientation ; and supplementary tape indexing apertures (8) corresponding to the fastener retention apertures for fastener positioning.

摘要:
Machine for assembling blind rivets comprising a circular disc (1) or plate provided with a number of equidistant radial grooves cut by two circular grooves (2, 3) near the edge of said disc (1), dividing said radial grooves in two areas (4, 5); tubular rivets and mandrils are deposited in each outer part (4), resp. in each inner part (5) of said radial grooves. A stationary cam (11, 12) is mounted at the center of said disc (1), such that uniform rotation of said disc (1) causes progressive introduction of the mandrils into the tubular rivets.
摘要:
A blind fastener installation tool (40) as well as a blind fastener and a core bolt for the blind fastener, both being adapted for use with the installation tool. The installation tool (40) has coaxially disposed first and second tool engagement members each engageable at one of their ends, respectively, with a drive stem (26) of a core bolt (22) of the blind fastener, and a bearing surface forming element of the blind fastener, and an axial through passageway (66) through the first tool member for removal of the drive stem (26) from the tool at a location remote from the engagement ends of the tool engagement members. The core bolt (22) has an elongated main body having a head (24) at one end, a taper at the other end, a breakneck (18) therebetween, and an elongated drive configuration extending along the entire portion of the core bolt between the breakneck and the taper.
摘要:
Methods and apparatuses for continuous fastener feeding for sequentially delivering single fasteners to a fastener installation device are disclosed. In one embodiment the apparatus includes a first fastener reel for supporting a first fastener tape securing a plurality of fasteners and a second fastener reel for supporting a second fastener tape for securing a plurality of fasteners. A fastener tape joining device positioned downstream of the first and second fastener reels receives the respective first and the second fastener tapes and selectively engage the first and second fastener tapes when one of the fastener tapes becomes depleted of fasteners.
摘要:
A rivet collating system is provided that includes a rivet holder for supporting rivets in a predetermined pattern. In one form, the rivet holder includes a unitary plate in which apertures are configured for supporting the rivets depending therefrom. In another form, the collating system includes a plate body and drive heads that are integrally connected via frangible portions to the plate body. Preferably, retaining webs are provided about the apertures to releasably hold the rivet heads therein. The drive heads are driven downward to sever the frangible portions with the webs flexing to release the rivet heads so that the rivets can be received in bores of a guide block of a belt fastener installation tool. A method of manufacture of the rivet holders is also disclosed.
