Abstract

The fuller die, which is used for elongated components, is a type of perform die employed in the closed-die forging process. In this research, using the finite-element method and the model test technique, both the required load and material flow are studied for the four-blow fullering operation. The experiments are conducted using lead as the model material and steel tools. Comparison of the numerical predictions and experimental results show a good agreement between them. For the extension of various process variables, FEM simulations are performed using ANSYS commercial software. Then, by means of linear regression and based on the finite-element results, some useful relationships are proposed for prediction of elongation, sideways spread and the required load for the four-blow fullering process. The designers can use the results of this investigation for prediction of elongation, sideways spread and fullering load instead of time consuming and expensive experiments
