Investigation of Effect of Clearance between Die and Punch in Deep Drawing Process

Chandra Pal Singh, Geeta Agnihotri

Abstract


Deep drawing is one of the significant manufacturing methods used to create automotive parts. The popular execution of process yields when product has minimum defects. Die design, punch nose radius, punch velocity, blank holder force and friction are the main parameters affecting product quality in deep drawing. Clearance between die and punch also plays an important role in deep drawing process. In this research article clearance has been varied from 0.2 to 0.3 of sheet thickness. Results at various clearance values are compared on the basis of thickness distribution, percentage thickness variation and maximum von Mises stresses induced in the drawn part shows significant effect of clearance. Results suggest that an optimum value will result in good quality product. Keywords: clearance, percentage thickness variation, thickness distribution, von Mises stresses
