A riveting system, for use in mechanically linking adjacent workpieces, including a rivet having a height greater than a sum of thicknesses, measured along a line of riveting, of the workpieces being linked, so that the rivet can pass fully through the workpieces. The system also includes a riveting die, which may be a separate product. The die includes a protrusion extending from a peak toward a transition point; and a trough having a trough surface. The trough surface includes a trough inner wall, extending from the transition point to a trough bottom, and a trough outer wall, extending from the trough bottom to a trough outer edge. The technology also includes computerized systems for comparing a load-displacement profile of riveting to a pre-set profile to determine whether the riveting was performed properly.

A clutch apparatus for releasing the transmission of rotation from an electric motor to a spin shaft, is equipped with a rear clutch nut and a front clutch nut in order from the rear end side. The rear clutch nut transmits rotating force from the electric motor to the front clutch nut when engaged with the front clutch nut, but is disengaged from the front clutch nut by a predetermined rotation load. The front clutch nut has a cylindrical shape, so that the spin shaft can be arranged at an axial center portion, and when engaged with the engaging unit of the spin shaft, the rotating force is transmitted to the spin shaft, but the clutch is disengaged by a backward stroke of the front clutch nut and a predetermined stroke toward the tip of the spin shaft.

The present disclosure relates to riveting apparatuses, riveting devices, and methods for their use. An example riveting apparatus includes a pneumatically operated riveting tool having a working end for squeezing a rivet. The riveting apparatus includes a support bracket connected to the riveting tool proximate the working end, the support bracket having arms projecting on each side of the riveting tool. The riveting apparatus also includes a pair of spaced-apart edge rollers coupled to the support arms. The edge rollers are configured to rollably engage an edge of a work-piece so as to support the weight of the riveting tool and enable movable adjustment of the working end relative to the work-piece. The riveting apparatus includes a handle rotatably mounted to the riveting tool to enable axial rotation of the handle, the handle having an actuatable switch configured to selectively operate the riveting tool.

A hydraulic power tool is provided including a rivet squeezer comprising two opposing surfaces, a hydraulic cylinder configured to move the surfaces between an open position and a compressed position, a hydraulic pump configured to provide hydraulic pressure to actuate the hydraulic cylinder in a first direction, and an air tank configured to provide pneumatic pressure to actuate the hydraulic cylinder in a second direction. Actuation of the hydraulic cylinder in the first direction causes the surfaces to move from the open position to the compressed position and actuation of the hydraulic cylinder in the second direction causes the surfaces to move from the compressed position to the open position.

A fastening tool includes a motor, a fastening mechanism, a tool body and a main handle. The motor includes a motor body and a motor shaft. The fastening mechanism is configured to fasten workpieces via a fastener by pulling a pin of the fastener rearward relative to a tubular part of the fastener along a driving axis defining a front-rear direction of the fastening tool. The tool body houses the motor and the fastening mechanism. The main handle extends in a direction crossing the driving axis and connected to the tool body such that the main handle and the tool body together form an annular part. A rotational axis of the motor shaft extends parallel to the driving axis. A portion of the main handle is located in a rear space extending behind the motor body.

A C-shaped frame for a cold-joining tool has two leg sections spaced apart from one another and a connection section. A punch unit and a die unit are provided opposite one another to define a tool axis. The C-shaped frame has a first surface side and a second surface side. An outer contour of the C-shaped frame is determined by an outer edge of the C-shaped frame in the transition between the two surface sides. The C-shaped frame includes a reinforcing section provided on the outer edge along the outer contour of the C-shaped frame. There are multiple portions of the reinforcing section, each with an associated thickness dimension of the portion, over a profile of the reinforcing section as seen along the outer edge. The extent of the respective portions along the outer edge and parallel to a surface side is in each case at least 30 millimetres.

A blind rivet nut-setting tool for setting a rivet nut including a housing having an anvil, a pull stud for engaging the rivet nut, and an output shaft defining a drive axis. The tool includes a motor defining a motor axis. The motor is configured to transfer torque to the output shaft to rotate the pull stud about the drive axis. The tool includes a clutch mechanism that is disposed between the motor and the output shaft. The clutch mechanism is moveable between an engaged state, in which a reaction torque exerted on the pull stud is below a predefined torque threshold, and a disengaged state, in which a reaction torque exerted on the pull stud is equal to or above a predefined torque threshold. The tool includes a pull mechanism that is driven by the motor and capable of translating the pull stud along the drive axis.

A fastening tool includes a motor, an anvil, a pin-gripping part, a magnet having the north pole and the south pole aligned in a front-rear direction and configured to move integrally with the pin-gripping part in the front-rear direction, a first magnetic sensor having a first sensing surface, a second magnetic sensor having a second sensing surface and disposed rearward of the first magnetic sensor, and a control device configured to move the pin-gripping part rearward based on a detection result of the second magnetic sensor and to move the pin-gripping part forward based on a detection result of the first magnetic sensor. The first and second magnetic sensors are unipolar detection type sensors configured to detect a same specified pole of the magnet. Orientations of the first sensing surface and the second sensing surface relative to a movement axis of the magnet are opposite to each other.
