Mechanical presses - mechanical presses should get a big development in the 1970s and 1980s. And a large amount of production of forgings product. Presses automatic production line is the idea of ??the ring gear of the Russian people, the German practice of Chinese human trials. The world's first fully automated production line installed in our forging Dongfeng Motor Corporation Forge. Forging presses in recent years the problems have not yet found a complete solution within the ring gear manufacturers, but it has been found, press forging its elongated frame certain controllable. In general, you want to stretch the press at work every 10MN 1mm. Without this stretch, it is impossible to achieve forging presses. Since the deformation of the sample in this case is not a simple stress state, but should be seen as a complex structure of. So the question we face is that the test results of the constitutive parameters of how the anti-calculated from a complex material structural deformation. On the trunk of the material it has been established it can not have an inverse, but for physical OAU lines and geometric nonlinearity strong temperature forging process, this approach will not do anything. Within wind power ring forging process _ Super League (certified) _ within Sanmenxia ring forged by Luoyang Super League Limited. Luoyang Super League Forging Co., Ltd.
