Screw press - screw press by past human spiral hammer forging furnace, double-disc friction press, the development of today's clutch screw press and direct drive screw press. The new press is characterized by a high energy forging process, and power can be controlled. Direct drive screw press with high efficiency, simple structure, etc. bearing forging, the main problems existed in the past is the impact on the grid, the current through the use of variable frequency technology to the problem is basically solved. Elastoplastic model calculations accurate, but due to the judge to increase the yield and unload the calculated amount. Rigid-plastic model is relatively simple, but can not simulate springback calculation process. In these models typically only consider the strain hardening. Up to consider the dynamic response, and therefore meet the general requirements for cold and warm forging process simulation. But for those who have accompanied the process of forming the microstructure changes in circumstances (such as forging, superplastic forming) the use of the traditional constitutive relationship will produce a lot of errors.
