| Abstract: | In this paper,the optimum calculation formulas with maximum elastic limit on two-layer asscmblicd cavity die of cold exlrusion are derived from the elastic solution of thick-wall cylinder. Then, the maximum extrusion stress, radius and interference of interface on two-layer assem-blied cavity die of cold extrusion can be calculated by above formulas. |
