The Comparison and assess of Calculating Methods of Backward Extrusion Pressure for Aluminum Alloy Cups |
| |
| Abstract: | In extrusion production, pressure is one of the most important technological parameters, but it is not easy to estimate it accurately in various situations. Through the comparison and assess of calculating methods of backward extrusion pressure for aluminum alloy cups, the calculating methods close to measured values under different deformation degrees are obtained. It is tested and verified that the result is reliable which can be used to guide production. To the same problem under other conditions (different extrusion types,materials,ets),the corresponding conclusions may be drawn referring to this kind of research means. |
