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.

Riveted assemblies are provided that can include a substrate extending between two ends to define opposing substrate surfaces having a first opening extending between the opposing substrate surfaces; a metal-comprising substrate extending between two ends to define opposing metal-comprising substrate surfaces having a second opening extending between the opposing metal-comprising substrate surfaces. The riveted assemblies can further provide that the first and second openings complement one another when the substrate and metal-comprising substrate are engaged; and a rivet shaft extends through the openings and engages the substrate with the rivet head and the metal-comprising substrate with the rivet stop head, at least a portion of the stop head being mixed with, and forming a metallurgical bond with the metal-comprising substrate. Assemblies are provided that can include a rivet stop head mixed with, and metallurgically bonded with a metal-comprising substrate.

Methods for affixing substrates to one another are also provided. The methods can include providing a substrate defining an opening configured to receive a rivet shaft; providing a metal-comprising substrate defining a complimentary opening; operatively engaging the substrates with the rivet shaft; and forming a stop head from the rivet shaft to affix the substrates. The method further includes that the stop head mixes with, and forms a metallurgical bond with the metal-comprising substrate. Methods for mixing materials to form a metallurgical bond are also provided. The methods can include forming a metallurgical bond between a stop head of a rivet and a metal-comprising substrate.

A die for deforming a workpiece material in a joining tool comprises a head with a top side partially defining a cavity in which the workpiece material is to be deformed, a bottom side opposite the top side, a lateral side arranged between the top side and the bottom side, and a stem which extends along a longitudinal axis from the bottom side of the head. The die further comprises an identification tag, preferably an RFID tag, having an antenna for receiving and/or transmitting a signal, and a storing element for storing information, and the antenna is wrapped circumferentially around the head, such that the antenna entirely surrounds the head. The head may also include a groove extending around the head on the lateral side with the antenna arranged in the groove. Additionally, the die may include a recess with the storing element located in the recess.

The invention relates to a joining unit (10, 40) for an articulated arm robot (12, 44) for joining a component (24, 58) with a joining element (28, 60) by applying an axial force. The joining unit (10, 40) comprises a base element (14, 42) for connecting to an articulated arm robot (12, 44). The base element (12, 42) is connected to an advancing unit (13, 46), which can be moved relative to the base element (14, 42) in an axial direction in and against a setting direction. The advancing unit (13, 46) is connected to a setting device (16, 54), which can be moved together with the advancing unit (13, 46). Furthermore, a pressure piece (26, 50) mounted for movement relative to the advancing unit (13, 46) in and against the setting direction is connected to the advancing unit (13, 46) by means of a coupling unit (17, 48). The invention is distinguished in that the coupling unit (17, 48) comprises a blocking unit (18, 56), which, starting from a predefined axial blocking position, prevents motion of the pressure piece (26, 50) relative to the advancing unit (13, 46) against the setting direction so long as the advancing force is less than the set blocking force. The blocking unit comprises a release device (20, 62), by means of which the relative motion of the pressure piece (26, 50) against the setting direction is enabled.

A safety power assist for a manual press is provided. In another aspect, a press includes a tool, a manual actuator, a switch and an automatically powered actuator. A further aspect of the present press employs a spring which must be compressed beyond a predetermined pinching force before a switch is activated, where switch activation causes an automatically powered actuator to advance a workpiece-contacting punch or tool.
