Comparative Study of Comprehensive Performance on Typical Die Structures in Knuckle Hot Forging

摘要：

　　In order to improve the severe service conditions and balance the needs between the better filling capacity and longer die life,a new flash structure named by resistance wall was introduced into knuckle hot extrusion dies.Focusing on filling capacity,the maximum deformation load and the highest die surface-layer temperature,different die structures,such as flash slot structure,traditional closed die structure and resistance wall structure,were comparatively analyzed by FEM simulation.It is shown that the resistance wall structure can be extensively used in many applications thanks to its comprehensive performance.
