摘要： The invention relates to an apparatus comprising an advancing device and a blocking device (4), having a lever (40) that is adjustable between a blocking position and a releasing position, and to a method for positioning connecting elements, wherein a connecting element (2) is transferable by means of the advancing device (3) from a receiving region (I) into a delivery region (II) for a joining device, wherein the at least one lever (40) prevents any movement of the connecting element (2) from the receiving region (I) into the delivery region (II) in the blocking position and enables same in the releasing position, and wherein, by means of an end stop, any movement of the lever (40) from the blocking position into the releasing position is preventable. The at least one lever (40) is designed as a two-sided lever (40) having a first arm (41) and a second arm (42), wherein a first arm (41) of the at least one lever (40) interacts with the at least one end stop in order to prevent any movement of the at least one lever (40) from the blocking position into the releasing position, and a second arm (42) of the at least one lever (40) acts, in the blocking position, as a retaining jaw for the connecting element (2). The invention also relates to an apparatus for setting connecting elements.

摘要： A screwdriver drive design for a screwdriver features an engagement end that is complementary to a fastening element drive design for a fastening element to be screwed. The fastening element drive design includes at least two drive surfaces formed on the fastening element for transmission of a torque suitable for rotation with a tool in a first rotation direction and transition surfaces disposed between these drive surfaces. The transition surfaces form a guide surface for the tool when rotating the tool in the first rotation direction and upon engagement of the tool in the other rotation direction causes an axial outward displacement of the tool, wherein the transition surfaces are formed as outside surfaces, and wherein the outside of the fastening element, outside the transition surfaces and the drive surfaces, lies in a cylindrical jacket forming a recess.

摘要： The present invention relates to a connecting element for non-detachably connecting at least two components by means of friction welding when the connecting element is rotated about a longitudinal axis of the connecting element. The connecting element includes a stem formed along the longitudinal axis with a stem face at a free end of the stem for penetrating at least one component, and a head connected to the stem for transmitting a torque about the longitudinal axis from a turning tool to the stem. The stem face has a stem end face which has a convex envelope with a blunt shape.

摘要： A device for inserting an auxiliary joining part into a workpiece, having a punch pressing the joining part into a top of the workpiece. The joining part has a shaft pressed into the workpiece and a die contacting a bottom of the workpiece while the joining part is pressed in. The die has a contact region and non-circular aperture surrounded thereby. Radially outermost points of the aperture periphery lie on an imaginary circumscribed circle, and radially innermost points lie on an imaginary inscribed circle. The aperture periphery includes three projections protruding into and touching the circumscribed circle. A diameter of the inscribed circle is between 4% and 10% smaller than a maximum diameter of a circular circumference of the auxiliary joining part, and a diameter of the circumscribed circle is between 2% and 5% larger than this diameter.
