Abstract

The present work addresses the topic of die clamping at the forging hammer in the context of the definition of a current requirement profile as well as the evaluation of individual influencing variables on the clamping process. In addition to the presentation of survey results for the requirements profile, the first part focus on the sensible minimization of influencing variables to be investigated and on the verification of a possible evaluation method. Based on this, in the second part exemplary influencing variables on the clamping condition are investigated by means of FEM. Thereby it can be shown by way of example, that the heat flow of the forging process and the friction conditions between the clamping elements have a noteworthy influence on the clamping condition of the dies and that deviations in the clamping force can lead to significant damage.
