Explicit Analysis of Punch and Its Operation on Sheet

Maneesh Kumar, Trilok Chauhan

Abstract


Explicit analysis of the punching of a sheet is conducted in the present work. Punching involves parts like, punch which apply the force and is motion, sheet on which load is being applied, blank die which gives the shapes to the sheet and blank holder which holds the sheet on its situation. From the literature conducted it has been found that very few amounts of research have been conducted on the punching press operation of a sheet. Velocity and fixed support as types of boundary conditions have been considered, velocity has been given to the punch while die and holder have been kept fixed. Different values of velocity have been studied to study its effect on the deformation, strain and stress generated on the sheet. Two types of material have been studied, steel and aluminium. From the results it has been found that for amount of stress generated in the sheet made of aluminium is less compared to the steel. With increment in the punch speed gap between the stress generated in the aluminium sheet and steel sheet is increases which represent larger chances of failure. For low values of punch speed amount of deformation generated in the steel sheet is more compared to the aluminium sheet, but with increment in speed a reverse nature has been observed which represent less chances of failure of aluminium sheet compared to steel sheet. It can be concluded that for low punching speed operation steel is good while for high punching operation aluminium is good.
