摘要:
Verfahren zur Einrichtung eines mit einem, insbesondere elektrischen, Antrieb versehenen, handhaltbaren Nietgerätes zum Setzen von Blindnietelementen in einer Aufnahmebohrung, insbesondere von Blindnietmuttern und/oder Blindnietschrauben, an einen zu verwendeten Typ von Blindnietelementen, wobei das Nietgerät ausgebildet ist, während des Setzvorgangs eine Zugkraft (F) auf ein Zugelement des Blindnietelements aufzubringen, insbesondere wobei das Zugelement am Ende des Setzvorgangs an einer Sollbruchstelle vom Rest des Blindnietelements abreißt, wobei die Zugkraft (F), mit der ein Blindnietelement gesetzt wird, durch einen einstellbaren Maximalwert (Imax) definiert wird, der während der Einrichtung festgelegt wird, das Verfahren umfasst die folgenden Verfahrensschritte: Durchführen eines Setzvorgangs mit einem Blindnietelement des zu verwendeten Typs; Erfassen eines Verlaufs der Zugkraft während des Setzvorgangs, Ermitteln zumindest einen charakteristischen Wertes (IA) aus diesem Verlauf, Festlegen des Maximalwertes (Imax) als Funktion des charakteristischen Wertes (IA).
摘要:
A blind riveting apparatus (1) comprises a motor (3), and a clamp (31) for gripping the mandrel of a blind rivet, the clamp being movable substantially along the axis of the rivet. The apparatus further comprises a first transmission (51) configured to transfer rotary motion of the motor (3) to the clamp (31) when engaged; and a second transmission (52) configured to convert rotary motion of the motor (3) to linear motion of the clamp (31), and thereby retract the clamp (31) to pull on the mandrel, when engaged. A transmission control apparatus is arranged to selectively adjust the degree of engagement of at least one of the first (51) and second (52) transmissions, the transmission control apparatus comprising a variable-influence brake or clutch (58). Methods of blind riveting, and further pieces of blind riveting apparatus, are also disclosed.

A swaging tool (1) whereby a collar fitted to the pintail side of a fastening pin in which the pinhead of the fastening pin is positioned at one plate member and the pintail of the fastening pin is positioned at another plate member is crimped to the fastening pin while pressed against the other plate member, and a tensile load is applied to the pintail to break off the pintail and fasten the pair of plate members together, wherein: the swaging tool (1) is provided with a holding member (12) for holding the pintail of the fastening pin, a swaging die (11) pressed against the collar and provided with a crimping hole (19) for crimping the collar, and a stroke mechanism (13) for expanding and contracting the space between the swaging die (11) and the holding member (12); and the stroke mechanism (13) has a rotating rotary member (25), converts the rotary movement of the rotary member (25) to the expanding and contracting action of the space between the holding member (12) and the swaging die (11), and restricts the rotation of the swaging die (11) and the holding member (12).
摘要:
A blind rivet fastening device in which a passage for collecting broken mandrels is provided other than on the axis of the motor. A large collection chamber is provided for broken mandrels. A collection chamber for broken mandrels is provided in front of a brushless electric motor in the axial direction. When the electric motor rotates, power from the electric motor is transmitted to a spindle positioned to the rear of the collection chamber via a second shaft positioned below the collection chamber. When the spindle rotates, a pulling head moves in the axial direction. The axial position of the pulling head is determined by detecting the rotation count of the electric motor. Forward rotation, reverse rotation, and stopping of the electric motor are controlled based on the operation of a trigger and the axial position of the pulling head. Excessive torque is avoided by clutches.
