Integration of functions through rotary swaging – New possibilities for the monitoring of states and loads in tubular machine elements.
In: New Developments in Forging Technology 2015, [Conference or Workshop Item]

Abstract

This contribution presents procedures of rotary swaging, which can be used to integrate sensitive sensor elements safely into load-bearing structures during shaping processes. Inside the tubular structure the sensor elements are protected from external perturbation. The high degree of freedom of the design for the inner and outer tube contour, which is given by using the rotary swaging technology, allows the creation of undercuts. This creates the opportunity for a form fit between sensor elements and load-bearing structures. Through the selective design of the transition section the sensor body is, on the one hand, protected against overstraining during rotary swaging and, on the other hand, an axial preload is achieved through a targeted flow of the tube material. For material bonds created in such a way can deliver important information about process monitoring already for the production process. In their future application they can be used for monitoring of forces and changes of states. In this contribution aspects of material flow figuration and the targeted adjustment of the aspired preload forces are being presented.
