Investigation of spring angle of sheet metal with rolling angle of 45o in V-die bending process

Abstract

 Structural elements made from steel sheet metal have a greatimportance in today's industry. One of the biggest problems with the parts bended by using dies is the spring angle because it destines bent sheet metal out of manufacturing tolerances. So, it is vital to know a part’s spring angle properties in advance which are mainly dependent on the properties of the sheet metal and bending conditions. This study aims to investigate the effects of bending angle and punch radius on spring angle of sheet metal with rolling angle of 45o in V-die bending process. After being removed from the bending dies spring-back rates of the specimens were measured by using optical goniometer.
