| Abstract Scope |
After wire drawing the residual stress state of the wire are unfavourable for the production of torsion bars. High tensile residual stresses typically occur on the near-surface layers of the wire. Additional procedures like shot peening are required to enable further processing. In these study an approach to adjust the residual stress state directly in the forming process of the wire is presented. Lower tensile stress levels on the near-surface layers of the wire shall be generated by modifying the drawing tools with integrated forming elements. These elements influence the material flow and in this context the plastic deformation without effects on the part geometry. On the basis of FE simulations the influence of the elements on the residual stress state of the wire will be identified. The experimental tests are realized based on these results. The residual stress state of the specimens is characterized by X-ray diffraction. |
