Abstract: A method as well as an apparatus manufactures a punch riveted joint, wherein at least two layers are pressed by a holding-down device against the die and a rivet, in particular a semitubular rivet, is provided for joining the layers. The holding-down device is connected by a coupling unit to the punch in such a way that during a punch riveting operation a coupling of the holding-down device to the punch may be varied between a substantially rigid coupling state and an uncoupled state.

Abstract: The punch (2) and holder (1) are moved to and fro in relation to a matrix (3). At least two layers (4,5) of components are clamped between the holder and matrix. A punched rivet (8) for joining the layers is driven through the layer (4) at least next to the holder, by the punch. A controller (27) controls a unit (6) comprising a coupling (7), connected to the holder.

Abstract: Process for removing punch rivets set into a workpiece with an upper die side which drives the punch rivet and an opposing lower die side penetrating into the workpiece, the punch rivet being provided with a peripheral cutting edge on the lower die side and the upper die side respectively, wherein a pin is placed with its end face on the upper die-side cutting edge, which pin heats the contact region of pin and cutting edge up to a fusing temperature in the contact region by supplying energy through the pin, whereupon after cooling of the contact region the pin is withdrawn counter to the pressure of an abutment resting on the workpiece while entraining the punch rivet withdrawn from the workpiece in the process.

Abstract: A punch rivet (1) has a cutting edge (6) which is arranged on the end face of its rivet shank (2) and is formed in the cutting region by an outer face (5) extending parallel to the axis and a conical inner face (4) of the rivet shank (2). The outer face (5) extends continuously parallel to the axis over the entire rivet shank (2) and the punch rivet (1) is provided with the same cutting edges (6, 7) on either side in an axially symmetrical design in the form of a tube.

Abstract: Force is applied to a C-shaped counterforce structure (9) carrying a workpiece (6) to produce deformation. Operating force is corrected to a predetermined amount, to produce a uniform deformation by measuring the deformation. Independent claims are included for the following: (1) a riveting device; and (2) a piercing device.
