| Abstract Scope |
In forging processes, the determination of blow efficiency is very important, as it quantifies the part of the stroke energy actually transmitted to the billet. Thus, forging processes should be deeply analyzed in order to better understand the stroke energy conversion, accurately estimate blows efficiency and thus better predict process parameters. In this paper, a spring-mass-damping vibration model is proposed to describe the behavior of a screw press. A simulation of the upsetting of copper specimen is performed with a FE software with no consideration of the press behavior. Then, forging load from the FE simulation is used to perform simulation of the whole forging process with the press model. Results show that the model is relevant to simulate forging load and ram displacement. Moreover, simulation can predict the distribution of the energy during the simulation and the blow efficiency can be calculated. This new way to obtain blow efficiency might improve productivity in process development and provide a better understanding of energy driven machine. |
