| Abstract: | Using elastic solution of thick wall cylinder, it is analyzed that the optimum design on three-layers assembled cavity die of cold extrusion under the elastic limit stress. It is inferred that the optimum design formulae of limit pressure bearing capacity, diameter and interference fit capacity of boundary between different layers. It is carried out that the optimum design of geometric parameters on three layers assembled cavity die of cold extrusion by interfered formulae. |
