|Project title||Development of a retrofit system for screw presses for (partial) automation and minimization of setup time and development of a sensor array for the first-time recording of elementary process variables, for example the forming force (AutoPress)|
|Project duration||01.10.2022 – 30.09.2024|
Screw presses are a commonly used method for manufacturing pressed parts, with a total number of over 500 production lines. The quality of the setup of screw presses currently depends primarily on the experience of the employee. In addition to employee know-how, the long set-up time is also a challenge, especially for small and medium-sized enterprises (SMEs) with low production volumes and a high degree of flexibility.
Together with JOBOTEC GmbH, IPH is developing a novel automated setting procedure for the process parameters of a screw press as part of this research project. The first direct measurement of the forming force and a novel optimization algorithm for the setup and process control of screw presses will reduce the setup time and prevent a loss of know-how. Users receive a system that they can operate easily and adapt individually to their screw press.
Publications about the project
An elementary factor for influencing the process quality and the energy requirement of an energy-bound forming machine is the stored work capacity. At present, the forming energy is calculated via the work energy introduced into the system. Here, factors such as spindle torsion or frictional resistance are only taken into account roughly.
Within the framework of the research project "Development of a retrofit system for friction screw presses for automation and minimization of the set-up time and development of a sensor array for the first-time recording of elementary process variables such as the forming force" (AutoPress), which is funded by the Industrielle Gemeinschaftsforschung (IGF), the IPH - Institut für Integrierte Produktion Hannover gGmbH and JOBOTEC GmbH are striving for an automated process control of screw presses and are providing initial findings in this regard.
