| Abstract: | Adopting the finite element simulation combination trial, and studied the forming technique of thick wall cylinder and the establishment method that is suitable in the finite element model of his hot forming. By the way of simulation and trial contrasts,the relation of neck down and the forming technique, prefab blank size, mould size and cool condition is analysed and is optimised. The forming technique and prefab blank and die design .Finally the settlement scheme to eliminate the neck down is put forwarded. |
