| Abstract: | The bending accuracy of press brake has been influenced by uneven distribution of the pressure caused by elastic deformation of the slider and work bench,which has been analyzed in the text by use of elastic mechanics theory.Then the three kinds of deflection compensation methods have been introduced.The finite element analysis and simulation have been conducted on the hydraulic-compensation press brake.The deformation and pressure distribution of the bench before and after the compensation have been compared. |
