| Abstract Scope |
Recently, there occurs an increasing demand for high precision extra fine steel wires. In order to manufacture ultrafine wires with high accuracy, it is necessary to clarify processing behavior inside the wire. The purpose is to investigate change of mechanical state inside the wire that has been drawn multiple times. However, since it is insufficient to observe experimentally, elastic-plastic finite element simulation is applied to understand the properties. Some three-dimensional models to be machined continuously multiple times are prepared and analyzed. We compare multiple models with different die shapes and discuss mainly the effects of die shapes on wire's properties. In particular, it is successful that hardness is evaluated by our newly proposed methodology using materials mechanics. It is found that the smaller the die angle per pass, the smaller the difference in strain distribution inside the wire. The same tendency is obtained as the number of processes is increased. |
