A study on simulation of deformation during roll-forging process using system of special shaped and hat groove
Based on the characteristics of roll-forging process, a kind of special shaped groove is presented to improve the uniformity of material distribution, and decrease loading. Three-dimensional rigid-plastic FEM has been used for the simulation of the deformation process in the special shaped and hat groove pass rolling. This paper analyzes the velocity field of material flow, stress-strain field, the characteristics of the temperature field, the dynamic evolvement process as well as the force-time curve of mould, mould damage. Besides, the affect of hat groove parameter to material transverse flow and mould loading is also analyzed. Furthermore, the author summarizes the influence law for the formability of roll-forging. Application shows that system of special shaped and hat groove can improve the uniformity of materials distribution and increase broadening quantity of spring plates in the process of automobile front-axle roll-forging.
