| Abstract: | A three-dimensional model of press brake has been established.The principle of lower beam hydraulic compensation mechanism has been analyzed and designed.The finite element software CosmosWorks has been used to conduct the static analysis of lower beam on press brake.The deformation and stress distribution of lower beam have been quantitatively described.The deformation rules of hydraulic compensation device have been obtained by error analysis of the folding angle and comparative study on flexibility curves of press brake slider and upper surface of lower beam.It is verified that the hydraulic compensation system is capable of compensating for the lower beam,which provides theoretical reference for design and application of the hydraulic compensation mechanism. |
