| Abstract | Hole hydro-piercing-flanging is a new hybrid technology by using high internal pressure as the support medium instead of rigid die. By this process, holes can be punched and flanged successively on hydroformed tubular parts without secondary positioning and fabrication. However, punch shape as an important factor has not been concerned enough so far. In this study, the influence of punch shape on geometrical profile and quality of holes was investigated both by experiments and simulations with three different shapes of transition zone between the piercing punch and the flanging punch. Results show that the geometrical size of roll-over depth, straight-wall height, and thickness varied with punch shapes. Considering the quality of the hole’s edge, ellipsoidal punch is the best one with the largest smooth zone and the least damage, but the conical punch gives the worst results. Finally, the mechanism of hydro-piercing-flanging process affected by the punch shape was clarified by the stress and strain distribution during plastic deformation by finite element analysis. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
