| Abstract Scope |
Inhomogeneously heated billets can shorten or simplify forging process chains. This shall be achieved by setting various temperature fields within a billet, resulting in different yield stresses.
This study investigates the influence of inhomogeneously heated cylindrical billets on the forging process using FEA. For this, two inhomogeneously heated and three homogeneously heated reference process chains are developed and compared. Each process chain is optimized until form filling and no defects occur. They are evaluated based on the forming force, the necessary material and die abrasion wear.
The results showed a small time window for a successful forming for inhomogeneously heated process chains. Forming forces and die wear increase for inhomogeneously heated billets. However, they show up to 12.5 % less flash than homogeneously heated billets. This shows a potential for inhomogeneous heating to make forging processes more efficient. Subsequently, experimental tests will be carried out to verify the simulation results. |
