摘要： 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.

摘要： A self-piercing riveting (SPR) system includes a top sheet and a bottom sheet. The top sheet is layered above the bottom sheet and are disposed between a die and a blank holder. The SPR system further includes a barrier disposed between the bottom sheet and the die, wherein the barrier is configured to reduce stress concentrations during formation of a joint between the top sheet and the bottom sheet. The barrier may has a thickness between 0.8 mm and 1.0 mm and is made from a cold formed or a dual phase steel alloy.

摘要： The invention relates to a connecting element (10) having a hollow-cylindrical shaft (12) and a drive (16), via which the shaft (12) can be driven in a direction of rotation, wherein the hollow-cylindrical shaft (12) has at least one free end, wherein the drive (16) is arranged opposite the free end, wherein a hollow space is formed by the hollow-cylindrical shaft (12). The invention is characterized in that driver structures (22) acting in the circumferential direction of the hollow-cylindrical shaft (12) are arranged in the hollow space, which, projected on the lateral surface, are arranged to extend in the setting direction on the lateral surface, rectilinearly parallel to the element mid-axis (M) or with an angular deviation of at most 20° with respect to the element mid-axis (M), and/or are arranged at the end on the drive side.

摘要： The present invention discloses a riveting method and a riveting structure. The riveting method comprises providing a plate having a first side and a second side opposite to the first side; forming a wall portion on the first side of the plate, the wall portion having a first recessed area at its first side and a second recessed area at its second side opposite to the first side; placing the fastener in the first recessed area so that the fastener is adjacent to the first side of the wall portion; and applying a force to the wall portion from the second side of the wall portion so that the wall portion is deformed so as to at least partially enclosed the fastener. This technical solution can avoid unwanted indentation on the back of the plate.

摘要： Two piece tack rivets and method of forming holes for permanent fasteners. The tack rivets have a stem with a head on one end and a grooved region adjacent the other end, and a locking collar for fitting over the grooved region of the stem for deforming into the grooved region of the stem on applying a setting force between the locking collar and the stem. The head includes cutouts formed therein. The cutouts prevent the head from forming large chips or strips when drilled.

摘要： The invention relates to a hold-down device for a joining drive and joining drive with a hold-down device. The hold-down device includes a hold-down cylinder, wherein the hold-down cylinder provides a hold-down force by means of a pressurized chamber. The pressure chamber consists of the hold-down cylinder and a punch of the joining drive. The pressurization required for the provision of the hold-down force is provided by a hydraulic circuit of the joining drive. In the joining mode, the pressure chamber of the hold-down device is connected to a pressure accumulator of the hold-down device, so that a change in volume in the pressure chamber of the hold-down device has no noticeable influence on the pressure in the pressure chamber.
