Bending of Tailored Blanks Using Elastic Tools

Abstract:

Tailored blanks are suitable for the manufacture of lightweight structures due to the load-optimised design. However, the forming of tailored blanks is problematic because of the varying properties. Especially springback is a main challenge to focus on. An innovative process will be discussed which concentrates on the air bending process of sheet metal extended by a local application of a stress superposition to reduce springback.
