Titel
Spot-joining - new technologies in the field of joining by forming
Abstract
The object of this paper are new developments in the field of joining by forming. The possibilitiy of reducing the setting force in spot-joining operations by modifying the kinematics of the punch is described. This reduction of the setting force is not only an advantage because of the possible weight reduction of the joining equipment but also because it allows the integration of spot-joining by forming operations into hydroforming processes at comparable low fluid-pressure. Furthermore a new method of spot-joining by forming shall be introduced, where contrary to standard technologies like clinching or self-pierce riveting the die has no cavity and therefore a high concentricity tolerance between punch and die is obtained.
