- W2376659368 abstract "Link Ring is the key part of coal mine well, so it is requested to have a very high anti pull and anti-fatigue function Many defects usually appeared in the original forming process, such as enfold and short of materialSo in this paper we uses DEFORM 3D FEM simulation and analysis system, establishes the rigid plasticity finite element model of 722 link ring hot forming processThen its forming process is simulated and analyzed by 3D FEM and the defects are predictedThe original forming process is improved and optimized as there some defectsThrough the simulating, we found that the material flows furiously in the original process of flat bottomed storage, so it is easy to result enfold and short of material condition Based on the simulating results, an improved die is designed to avoid the enfold effectively and can get the qualified forging At the same time, it lowers the depletion of the material, increases the utilization ratio of materialand also because the periphery of the connect skin is thin, it is easy to be resected, so the life time of the die is increased" @default.
