Manufacturing of rotationally symmetric tailored blanks by a compression and flexible rolling process (DGF SFB/TR73 - A1/1)



Project Status: finished

Members


Manufacturing of complex sheet metal components containing functional elements can be enabled by the application of bulk forming operations on planar semi-finished products. Considering a large contact area the forming process requires innovative concepts to reduce the forming forces. Within the subproject the manufacturing of process adapted tailored blanks with a defined sheet thickness characteristic and locally adapted mechanical properties is investigated. The applied forming processes are upsetting and flexible rolling. Aim of the project is the setup and fundamental scien-tific analysis of both forming processes. The prototypic rolling machine with a flexible process strategy enables the realisation of various blank layouts, designing the semi-finished products for successive forming operations.
