| Abstract: | There is effect of pre-applied force of drag bolt on accuracy of press with closed combined frame. ANSYS FE program has been used to analyse a new Germany forging press resulting in effecting law of pre-applied force of drag bolt on accuracy of press with closed combined frame hence important guiding sense and applicable value to improvement on design and manufacture accuracy of similar type of forging press of China. |
