Numerical Investigations on Stresses and Temperature Development of Tool Dies during Hot Forging

Hot-forming tools are subjected to high thermal and mechanical stresses during their application. Therefore, a suitable design of the tool die is important ensure long life. For this purpose, numerical simulations can be used calculate occurring temperature development in course stroke or over several forging cycles. The aim research investigate effect different radii on resulting lower forming tools. Furthermore, evolution cycles analysed determine temperature. When investigating stress, it was found that larger radius leads reduction stresses. In addition, could numerically proven base levels off after certain number These findings will further dealing with service life calculation dies thermo-mechanical alternating
