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.

A screwdriver (1) includes a guide member (2) for guiding a screw strip (7) that carries a plurality of screws (7b) arranged at intervals along a length of the screw strip (7). A feeding device (6) feeds the screw strip (7) such that the screws (7b) of the screw strip (7) are positioned one after another to oppose to a position for driving by a driver bit (5g). The guide member (2) defines an arc-shaped guide path having a length, so that the screw strip (7) can move along the guide path. The guide member (2) is configured such that the length of the guide path can be varied at least between a first length and a second length that is longer than the first length. The present invention may also be applied to power tools for driving nails and rivets.
摘要:
An apparatus for setting fastening elements (5) has a feed drive (21), with which the connecting elements (5) can be fed to a fitting position, and a setting device which has a setting tool and with which a fastening element (5) arranged in the fitting position can be ejected in order to come into engagement with a support part. Furthermore, there is a drive device which has a drive motor, which has a rotatable drive shaft (13) and is coupled to the feed drive (21) and the setting device (30) via a transmission arrangement (14, 15, 16, 17, 18), and a control arrangement for setting the direction of rotation of the drive shaft (13). The transmission arrangement (14, 15, 16, 17, 18) couples the drive motor (12) to the feed drive (21) in one direction of rotation of the drive shaft (13) and to the setting device in the other direction of rotation of the drive shaft (13). As a result, the apparatus is relatively simple to manipulate.

摘要:
A rivet carrying device for holding and sequentially feeding rivets into an automatic rivet setting device comprises an elongate strip (150) of thin flexible material having a plurality of blind rivets (R) connected in spaced apart relation along the length of said flexible strip (150) by having the distal portion of each mandrel pierced through and retained within said flexible strip (150).
摘要:
A feeder for headed fasteners, such as rivets (43), driven at equal intervals through a tape (44), is applicable to a riveting machine (10) and includes a plunger (25) advanced and retracted through a guide bush (29) and with a punch (37) at its leading end. When the plunger (25) advances the punch (37) is driven through a delivery passage in the guide bush head (39). A guide tube (45) leads the tape (44) to bring fasteners (43) in sequence into the rivet delivery passage (52). An actuator (56), oscillatable in the guide bush (39), is moved to retracted position by the advancing plunger (25), and is automatically returned to advanced position when the plunger (25) retracts. Fastener engaging means (64) on the actuator (56) act, with each retraction and advance of the actuator (56), to engage a fastener (43) and move it towards the delivery passage from which the leading fastener (43) is driven by the advancing punch (37) which, penetrating the tape (44) holds the tape (44) against movement while the actuator (56) is moved to its retracted position.
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:
Un dispositif d'alimentation pour éléments de fixation à tête tels que des rivets (43) enfoncés à intervalles réguliers au travers d'une bande (44) s'applique à une machine à riveter (10) et comprend un plongeur (25) qui est avancé et rétracté au travers d'un manchon de guidage (29) et un poinçon (37) à son extrémité d'attaque. Lorsque le plongeur (25) avance, le poinçon (37) est entraîné au travers d'un passage de distribution dans la tête (39) du manchon de guidage. Un tube de guidage (45) conduit la bande (44) pour amener les éléments de fixation (43) en séquence dans le passage de distribution (52) de rivets. Un dispositif d'actionnement (56) pouvant osciller dans le manchon de guidage (29) est déplacé vers une position de rétraction par le plongeur d'avancement (25) et il reprend automatiquement sa position avancée lorsque le plongeur (25) se rétracte. Des moyens d'engagement (64) des éléments d'attache sur le dispositif d'actionnement (56) agissent avec chaque mouvement de rétraction et d'avancement du dispositif d'actionnement (56) pour engager un élément de fixation (43) et le déplacer vers le passage de distribution d'où l'élément de fixation en tête (43) est entraîné par le poinçon d'avancement (37) qui, en pénétrant dans la bande (44) maintient cette dernière en l'empêchant de bouger tandis que le dispositif d'actionnement (56) est déplacé vers sa position rétractée.
摘要:
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.
