| Abstract: | After an analysis on cross-section and waste in punching of pipe free of cavity die,the deformation mechanism and cross-section schematic diagram of punching process free of the die were obtained.Software Deform-3D was used to study the stress-strain of punching process,which would provide reference to technology optimization of punching process free of cavity die. |
