A clinch-in fastener with a cylindrical body having a top, a bottom, sides and an axial internal bore. The fastener has a single shank at the bottom end of the body having a top surface 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 of a workpiece. The shank may have a plurality of notches in its outermost edge that extend through both the top surface of the shank and the chamfer. The bore of the fastener extends completely through the fastener body from top to bottom and may be threaded. A fastener installation system having a tool with means for affixation to a rotary and vertically reciprocal element of an industrial machine. The tip of the tool has a distal end face with at least one arcuate displacer adapted for deforming a workpiece as the tool rotates and is pressed against the workpiece. A bore within the tip holds a fastener installed by the tool. The displacer is vertically and radially tapered along an arcuate ridge centered about the axial bore. The width of the displacer is also tapered to a point.

The description relates to a joining head for fastening a fastening element by a die to the surface of a component with a gripper that can be linearly displaced in a first displacement direction R.sub.G and a magazine that can be linearly displaced in a second displacement direction R.sub.M . The magazine contains a plurality of fastening elements, with the first displacement direction R.sub.G running transversely to the second displacement direction R.sub.M.

A can end including a central panel and a coined rivet disposed on the central panel. A press, a station, and/or a tooling assembly structured to form a coined rivet as well as a method to form the coined rivet is also provided.

An assembly module, an assembly apparatus, and a method of operating the assembly module are introduced. The assembly module includes a first assembly die, a second assembly die and at least one engagement die. The first assembly die has a plurality of first fitting portions. The second assembly die has a plurality of second fitting portions and corresponds in position to the first assembly die. The engagement die is removably disposed at a related point of at least one first fitting portion, at a related point of at least one second fitting portion or at related points of at least one first fitting portion and at least one second fitting portion. Therefore, the assembly module is effective in fitting a component and an assembly target together, easy to operate, and conducive to quick assembly.

To solve a problem about warpage of a steel sheet due to a difference in temperature raising rate between an overlapped part and a one-sheet part. This manufacturing method includes: a step of heating an overlapped blank; a step of transferring the heated overlapped blank; and a step of performing presswork on the heated overlapped blank by using a die, in which in the heating step, when sheet thicknesses of the first and second steel sheets are set to t1 and t2, respectively, and an average heating rate at a sheet temperature from 20 to 800° C. of a portion with a total sheet thickness (t1+t2) of an overlapped portion, and that of a non-overlapped portion are set to V and v1, respectively, the total sheet thickness (t1+t2) is 2.5 to 5.0 mm, a maximum length L of the overlapped portion is 100 to 1100 mm, an area S1 of the first steel sheet, an area S2 of a portion, of the second steel sheet, which is overlapped with the first steel sheet, and the average heating rates V and v1 satisfy Expressions (1) to (3), and the heating is performed at a heating temperature and for a heating time within a specific range on a plane of coordinates defined by the heating time and the heating temperature.

A C-shaped frame for a cold-joining tool has two leg sections spaced apart from one another and a connection section. A punch unit and a die unit are provided opposite one another to define a tool axis. The C-shaped frame has a first surface side and a second surface side. An outer contour of the C-shaped frame is determined by an outer edge of the C-shaped frame in the transition between the two surface sides. The C-shaped frame includes a reinforcing section provided on the outer edge along the outer contour of the C-shaped frame. There are multiple portions of the reinforcing section, each with an associated thickness dimension of the portion, over a profile of the reinforcing section as seen along the outer edge. The extent of the respective portions along the outer edge and parallel to a surface side is in each case at least 30 millimetres.

The press-fitting method for press-fitting a plurality of clinching fasteners into a workpiece. The method includes: a drilling step S1 of drilling press-fit holes at press-fitting positions of the workpiece to press-fit first clinching fasteners that are press-fitted from a punch side of a turret punch press by NC control using the turret punch press; a workpiece mounting step S2 of mounting the workpiece so that the workpiece is superposed on a fastening jig that guides the first clinching fasteners; a fastener insertion step S3 of inserting a predetermined number of the first clinching fasteners taken out from a screw feeder into the press-fit holes of the workpiece; a fastener press-fitting step S4 of press-fitting the first clinching fasteners into the press-fit holes of the workpiece by NC control using the turret punch press; and a workpiece removal step S5 of removing the workpiece from the fastening jig.
