Influence of the Cut Edge on the Formability of Steel

Funding: ReCIMP
Contact: Dr.-Ing. Christian Löbbe

The sensitivity of sheared Advanced High-Strength Steels (AHSS) to fail at the sheared edge is a critical problem for the automotive industry.

Development of a Profile Bending Process with Compressive Stress Superposition by Rolling

Funding: LeitmarktAgentur.NRW
Project: EFRE-0400139
Contact: Juri Martschin M.Sc.

As part of this NRW patent validation, a process is developed that enables profile bending with compressive stress superposition.

Freeform Bending of Aviation-Relevant Tubular Parts

Funding: BMWi/DLR
Project: 20W1514B
Contact: Stefan Gallus M. Sc.

In cooperation with PFW Aerospace GmbH, Incremental Tube Forming (ITF) is qualified for the production of aviation-compatible tube structures made of titanium and titanium alloys.

Development of a Technology for Bending U-Profiles

Funding: BMWi/ZIM-ZF
Project: ZF4101104US6
Contact: Johannes Gebhard M. Sc.

Bending of metal profiles is currently restricted to high bending radii and, therefore, bent products are limited to spacious constructions.

Damage in Sheet Metal Bending of Lightweight Profiles

Funding: German Research Foundation (DFG)
Project: SFB/TRR188 • Subproject A05
Contact: Rickmer Meya M. Sc.

Profiles made of high-strength and ultra-high-strength steel materials are often produced by classic bending processes such as air and die bending.

Granular Media-Based Tube Press Hardening

Funding German Research Foundation (DFG)
Project TE 508/52-1
Contact Mike Kamaliev M. Sc.

Together with DLR (German Aerospace Center), the suitability of granular media as a forming medium for tube expansion at elevated temperatures is investigated in this project.
