Experimental Investigations on Effect of Process Parameters during Air Bending of Interstitial Free Steel Sheet
Keywords:
Air bending, IF steel, SpringbackAbstract
This work aims at studying the effect of major parameters, namely, punch velocity, punch radius and width of the sheetwith respect to material orientation to the rolling direction on air bending process of Interstitial Free (IF) steel sheets. An experimental work has been employed to analysis the sheet metals on bend force, springback and bend angle. It is observed that punch load increases as punch radius, punch velocity and width of the sheet increase. It is generally found that the springback exhibited a polynomial relationship with the punch travel. From the results, it is noted that, increase in the punch radius, punch velocity and decrease in width of the sheet increases the bend angle. The angle of springback decreases with increasing punch radius, width of the sheet and decreasing punch velocity.
