A method for operating an electrically-operated portable riveting machine includes providing an electrically-operated portable riveting machine and informing the user when it is necessary to empty the collecting vessel. The electrically-operated portable riveting machine includes a housing, a rivet setting mechanism arranged in the housing which sets rivet elements into workpieces to be connected, a collecting vessel, a delivery duct that delivers spent rivet mandrels created during a setting of the rivet elements into the collecting vessel, a spent rivet mandrel determination device which determines a number of the spent rivet mandrels in the collecting vessel, and a user information device which informs a user when it is necessary to empty the collecting vessel.

A method for setting blind rivet elements in which the setting of the respective blind rivet element introduced into a pre-hole of the work piece and/or the formation of a rivet collar takes place in a setting stroke (SH) through the permanent deformation of a section of the blind rivet element by subjecting an end of the blind rivet element to a traction force by a traction element of a setting tool while simultaneously supporting another end of the blind rivet element on a support part of the setting tool counter to the traction force.

A rivet dispenser and method for manually loading a handheld rivet gun. The handheld rivet gun may include an attachment port, and the rivet dispenser may have a unitary, single-piece tool body having channels formed therein, sized and shaped to retain heads of a plurality of rivets. The method may include grasping the rivet dispenser in a first hand, grasping the rivet gun in a second hand, and inserting an end of one rivet, extending outward from the rivet dispenser, into the attachment port, thus attaching the rivet to the handheld rivet gun. The method may then include sliding the one rivet through and out of the channel of the rivet dispenser, via movement of the rivet gun and/or the rivet dispenser. Finally, the method may include actuating the rivet gun to install the one rivet into a hole of a structure or structures to be joined together thereby.

A rivet for blind fastening may include a screw with a handling element, a break groove, a head separated from the handling element by the break groove, and a threaded part. The rivet may also include a sleeve with a collar and a tubular shank having an internal thread intended to come into engagement with the threaded part of the screw. The handling element includes a first handling portion able to guide introduction of the rivet in a setting tool, and a second handling portion able to transmit a torque, the two handling portions being separated by a blocking portion able to limit an axial movement of the rivet in a setting tool. A setting nose may be used for installing such a rivet, and the rivet, setting nose and a setting method can be used in the assembly of aircraft structures.

A tool is provided for installing a fastener, having a sleeve and a pin threadably received into the sleeve, into an opening of a structure. The tool includes a frame, a clamp mounted to the frame such that the clamp is configured to move longitudinally relative to the frame, the clamp being configured to grab a pintail of the pin of the fastener, a linear actuator operatively connected to the clamp such that the linear actuator is configured to drive linear movement of the clamp relative to the frame, a wrench mounted to the frame such that the wrench is configured to rotate relative to the frame, the wrench being configured to grab the pintail of the pin, and a rotary actuator operatively connected to the wrench such that the rotary actuator is configured to drive rotation of the wrench relative to the frame.

The present invention discloses a hand riveter and relates to the field of hand-operated tools, and the hand riveter comprises a first handle, a second handle and a clamping and pulling mechanism, wherein the second handle is capable of rotating around a pivoting shaft with respect to the first handle; the second handle is separated into a force applying end and a warping end by the pivoting shaft, and the warping end and the clamping and pulling mechanism are connected via a connecting shaft; when the force applying end of the second handle is rotated and opened with respect to the first handle, the warping end of the second handle drives the clamping and pulling mechanism to move in a rivet-driving direction; and when the force applying end of the second handle is rotated and closed with respect to the first handle, the warping end of the second handle drives the clamping and pulling mechanism to move in a rivet-pulling direction. According to rational arrangements of the present invention, the hand riveter is labor-saving and is comfortable to hold during pull riveting.

A two-piece, one-sided-installation fastener system may have an internally-threaded sleeve having a shank and a sleeve head. The fastener system may include an externally-threaded core bolt having a frangible driving provision and a core bolt head.

The invention relates to a riveting tool for setting blind rivet nuts and/or blind rivet screws, comprising a drive piston which is able to be hydraulically adjusted from an initial position toward an end position, a pull rod which is releasably and operatively connected to the drive piston and which is able to be adjusted by the drive piston from a rivet receiving position into a setting position and a coupling element fixing the pull rod and a drawing mandrel to one another in the longitudinal axial direction. In order to provide a riveting tool of the type mentioned above by which uniform setting processes of rivets may be carried out with a high degree of repeated accuracy, it is provided that the riveting tool for fixing the setting position has an adjusting unit with a stroke-limiting element which is axially adjustable relative to the coupling element in the longitudinal axial direction of the pull rod, said stroke-limiting element being in engagement with the coupling element via a stop surface in the setting position.

A blind rivet including a sleeve and a flange on one end of the sleeve, and a mandrel including a shaft and a head, the head having a cutting edge for cutting open the sleeve. The sleeve of the rivet body has a thick portion, and a thin which has an inner diameter larger than the thick portion. The shaft of the mandrel has a large diameter portion, a middle diameter portion, a small diameter portion having an outer diameter smaller than the middle diameter portion, and a securing and attaching groove which is between the middle diameter portion and the small diameter portion. When the blind rivet is fastened, the middle diameter portion of the mandrel causes the material of the thick portion to undergo metal flow and to flow into the securing and attaching groove, enabling the mandrel to be tightly secured to the rivet body.

The present invention discloses a one-hand-handled rivet gun, which has a handle seat with a through hole, a folding mechanism hinged to the handle seat and a pulling rod connected to the folding mechanism. The mentioned pulling rod is coated by a housing, and is equipped with a riveting gun tip assembly on the front end. A fixed sleeve is mounted on the front end of the housing of the pulling rod, and a guiding nipple is mounted on the front end of the fixed sleeve. The mentioned folding mechanism comprises two folding rod assemblies symmetrically mounted behind both sides of the rear end of the pulling rod, and the two folding rod assemblies include a front curved link and rear curved link hinged to each other. A handle cover is connected to the rear end of the rear curved link, and the front curved link is fixed to the pulling rod by the front end and hinged to the front end of the handle seat. Therefore, the invented one-hand-handled rivet gun can be used with only one hand, which is easy for people to use.
