In an embodiment of the method, a joining element is inserted into the two components, and during the joining process, at least one parameter quantifying the joining process is determined. The joining element is inserted by a robot and the at least one parameter quantifying the joining process is determined by the robot. A device for joining two components is also disclosed.

A servomotor control device in a processing machine that processes an object to be processed on a press supporting unit driven by a servomotor includes: a pressure detection unit configured to detect an actual pressure applied on the object to be processed; a pressure command generation unit configured to generate a pressure command that commands a pressure that the object to be processed preferably receives; a pressure control unit configured to generate a speed command for the servomotor on the basis of the pressure command generated by the pressure command generation unit and the actual pressure detected by the pressure detection unit; and a speed command limiting unit configured to limit the speed command generated by the pressure control unit using a predetermined value.

A crimping system of a fastening component onto a support, including a crimping tool comprising a housing and a traction rod configured to cooperate with the fastening component so as to deform the fastening component when a translation of the traction rod takes place, a fluid source connected to the housing to supply a fluid under pressure to move the traction rod, a sensor to measure the movements of the traction rod, a detector to provide a pressurisation information of the fluid in the housing, and a control unit configured to record a curve of the measured movements and the pressurisation information of the fluid in the housing.

A component for a window regulator system of a vehicle closure panel including: a rail having a rail aperture extending between a first side of the rail and a second side opposite the first side, the rail aperture having a retaining surface associated with the rail aperture; a pulley for mounting adjacent to the first side, the pulley having a pulley aperture with a pulley surface opposite the first side; a pulley rivet having a rivet body including a retaining lip for engaging with the pulley surface and a retainer portion for engaging with the retaining surface, the rivet body configured for receipt in both the pulley aperture and the rail aperture when installed, the rivet body having a hole for receiving a fastener for fastening the rail to a panel via the pulley rivet; wherein, when installed, the rivet body is positioned within the pulley aperture and within the rail aperture, such that engagement between the retaining lip and the pulley surface inhibits separation of the pulley from the rail while engagement of the retainer portion with the retaining surface inhibits separation of the pulley rivet from the rail aperture.

A method for configuring a hand-held riveting tool operated by an electric drive to set a blind rivet element in a setting operation. The hand-held riveting tool includes a mandrel configured to perform an axial movement so as to perform the setting operation of the blind rivet element, and a control unit which monitors the axial movement of the mandrel. The mandrel includes a front end position to which the blind rivet element is fitted in a form-locked manner and/or a force-locked manner. The method includes axially moving the mandrel from the front end position into a rear end position which is assumed at a beginning of the setting operation, and automatically adjusting the rear end position of the mandrel based on a parameter provided to the control unit.

A device for setting a connecting element on a workpiece includes a setting unit having a setting head which is movable in a feed direction into a working position, the connecting element can be fastened on the workpiece by the setting head, and a feed unit can feed the connecting element to the setting head. The feed unit is movable in the feed direction from an initial position into an intermediate position for transferring a connecting element to the setting head. A method for setting a connecting element on a workpiece by using the device is also provided.

A method is presented for operating a power tool during installation of a deformable fastener. The method includes: receiving measures of current supplied to a motor of the power tool during operation of the power tool; determining rate of change of the current during operation of the power tool; determining occurrence of the power tool engaging the fastener based on the magnitude of the current supplied to the motor; determining occurrence of the power tool swaging the fastener based on the rate of change of the current; determining completion of the power tool swaging the fastener based on the magnitude of the current and the rate of change of the current; and verifying quality of the installation of the fastener using the determination of the occurrence of the power tool engaging the fastener and the determination of the completion of the power tool swaging the fastener.
