Blechmassivumformung von Funktionsbauteilen aus Bandmaterial

Description

Sheet-bulk metal forming as an application of bulk forming processes to sheet metal combines the advantages of sheet and bulk metal forming. Thin-walled and thus lightweight components with integrated functional elements, such as gears or pins, are formed from flat semi-finished products by means of a three-dimensional material flow. This meets the goal of lightweight construction and realizes systems with sustainable application behavior.

In order to further increase the efficiency of sheet-bulk metal forming, the production of functional components from coil is being researched as part of the work. Forming from coil increases the output quantity compared to manufacturing with pre-cut blanks. The objective of this work is to develop a basic process understanding for the forming of functional components from coil. In this context, the coil-specific challenges and their causes with regard to the material flow and the tool loads are identified. Based on this, workpiece-, process- and tool-sided measures for material flow control are researched in order to extend the process limits. In the case of wear-critical measures, their application behavior is investigated in tool life tests and the suitability of the measures for the production of a high number of components is demonstrated. Finally, the results of the work are used to derive application-related recommendations for the sheet-bulk metal forming of functional components made from coil.
