Adaptive FDS/FLS joining

Mechanical engineering company DEPRAG is presenting an adaptive FDS/FLS assembly unit in Nuremberg that is equipped with a controlled electric drive for both the feed and the screwdriving process. This ensures that the optimum process parameters are achieved during every screwdriving operation.

 

The material mix in automotive lightweight construction means that joining processes such as flow-formed screw joints (FLS) are gaining ground and are continuously evolving. The control system of the "Adaptive DFS" (DEPRAG Fastening System) continuously determines the relevant actual values and adapts the process variables pressure force and screw speed in each case to the specified nominal values. This means that the optimum process parameters are achieved during each screwdriving operation. Errors that lead to costly repairs can be avoided. In addition, it is ensured that the screw and component are exposed to the lowest possible loads - regardless of the material and material pairing of the component.

Further advantages of the "Adaptive DFS" are shorter cycle times and optimum utilisation of the material-related limits of parameters such as speed and torque. The separate electronic control of feed and screw drive offers extensive parameterization possibilities. This ensures a high degree of flexibility when processing different materials and material combinations. Due to the controlled feed movement, precise feed sequences and change-over points for future materials can be defined. The screwdriving system also has an ergonomic, intuitive user interface. Comprehensive, integrated diagnostic functions form the basis for preventive maintenance and maximum system availability.
