    摘要： A clinch-in fastener (11) with a cylindrical body (13) having a top (13a), a bottom (13c), sides and an axial internal bore (12). The fastener has a single shank (15) at the bottom end of the body having a top surface (17) orthogonal to the bore and a chamfer tapering to the bottom of the body. The top surface of the shank is adapted for receiving the cold flow of material surrounding a receiving hole (23) of a workpiece (21). A fastener installation tool (20) has a tip (40) with a distal end face (24c) with at least one arcuate displacer (27) adapted for deforming a workpiece as the tool rotates and is pressed against the workpiece. A bore (30) within the tip holds a fastener (11) installed by the tool. The displacer is vertically and radially tapered along an arcuate ridge centered about the axial bore.

    摘要： The drive unit (4) is particularly designed for a (stamping) rivet setting device and has an electric direct drive (40) which comprises motor components that concentrically surround a control element (62) which can be linearly moved in the axial direction (8). In order to absorb the required torques while allowing a compact construction of the device, in particular in relation to a component side (12), a drive housing (10) has an asymmetrical design in a connecting region (21) between a main part (16) and a guide part (18) in which the control element (62) is guided, for the purpose of asymmetrical torque transmission. In addition or alternatively thereto, said highly compact construction achieves an efficient cooling by means of an inner cooling unit, in particular air flowing through a free inner space (76) in which the motor components are arranged.
