Method for connecting at least two components by the punch riveting method, device for carrying out the method, production apparatus and use of the method

A method for connecting at least two components 11, 12 by punch riveting, in which the components are arranged between a punch 15 and a die or holder-up 18. A rivet 20 is pushed by the punch 15 into the components 11, 12 to connect them in a force- and form-locking manner. During pushing-in, the rivet 20 and/or the at least two components 11, 12 are caused to oscillate by apparatus 30. The oscillations may be ultrasonic, preferably at a frequency of 15-40kHz and a stroke of 10-100 micro metres. The oscillations may be coupled parallel to, perpendicular to or at an oblique angle to the joining direction or in the circumferential direction of the rivet. The frequency and/or stroke may be altered during riveting. The apparatus 30 may be located on the side of the punch facing away from the rivet. The method may be used to join brittle materials such as light metals or composite fibre materials.
