Abstract
The long-core rail transfer flange heel end die forging die is slip-die forging die,and the forging die is multi-piece assembled,which has many shortcomings such as low yield and cumbersome process steps.Therefore,a new structure form of long-core rail transfer flange die forging die is designed in this paper to improve forging efficiency and finished product quality.Process analysis and reasonable mold cavity design were carried out based on the finished size of the heel end of the long core rail conversion flange,and 3-station mold model was constructed with 3D modeling software,processing deformation plan was formulated,material model was established,and simulation software(Deform-3D)was then used for simulation.The flow law of metal and the change of die load at each station during die forging of long core rail transfer flange heel end were tested,and the feasibility of designing a new type die of long core rail transfer flange heel end was finally confirmed.关键词
