Abstract:
Bei einer Vorrichtung zum Setzen von Befestigungselementen (1) lässt sich eine Vorlageschaftstange (14) über eine Vorlagekulisse (16) in eine vorgeschobene Setzstellung bewegen, um das Befestigungselement (1) auch an unzugänglichen oder vertieften Stellen setzen zu können.
Abstract:
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.
Abstract:
A fastener dispensing apparatus (1) for dispensing fasteners (11) to a workpiece, comprising a body through which a punch path is defined and a punch (6) at least partially within the punch path. The punch (6) is reciprocally moveable between a retracted position and an advanced position in which the tip of the forward portion extends from an end of the punch path in order to drive a fastener (11) towards the workpiece. A fastener feed path (P) extends transverse to the punch path and is defined in part by a surface (34) of the body, the fastener feed path (P) being arranged for receipt of an elongate carrier (10) of fasteners (11). The apparatus (1) further comprises a fastener feeding device for sequentially feeding fasteners (11) supported in the elongate carrier (10) along the fastener feed path (P) and into alignment with the end of the punch path.
Abstract:
A wire mesh rivet (13) is provided which is used to produce a wire mesh isolator (11) in a bore (9) of a substrate such as a heat shield (7) for a vehicle exhaust system. The rivet (13 ) comprises a unitary wire mesh structure (19) which has a collar (15) and a shank (17). The collar (15) has a higher density than the shank (17), e.g., the collar (15) has the density of the finished isolator (11). The rivet (13) is formed into the finished isolator (11) by compressing the shank (17) to form a second collar, while restraining the original collar (15) from substantially changing its shape. The rivet (13) can include a metal insert (23) which prevents the wire mesh of the finished isolator (11) from experiencing high levels of compression when the substrate is fastened to its supporting structure. The rivets (13) can be carried by a dispensing strip (31) and can be formed into the finished isolator (11) using forming equipment (39) whose dimensions are compatible with the limited space available with some substrates.
Abstract:
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.
Abstract:
A fastener carrier for fasteners for use in a riveting system, said carrier comprising at least one holding zone and at least one release zone, wherein said holding zone holds a fastener in a stored position and said release zone releases said fastener from said carrier, said holding zone having a diameter smaller than said release zone.
