DETERMINING SPRINGBACK AMOUNT OF STEEL SHEET METAL HAVE 0.75 MM THICKNESS IN BENDING DIES SHEET MATERIALS

Bending dies is very important in sheet metal industry. Since the material leaving the die should be obtained within the allowed tolerance limits, the amount of springback of bending material in bending dies is as important as the die itself. In this study springback amount of the materials in bending process were investigated. In order to obtain the springback in bending, a "V" shaped die was designed. It was aimed to obtain the springback amounts of steel sheet metal have 0.75 mm thickness for various bending angles and the springback graphics in 6 different dies and 10 samples, were bent in different angles and after bending process final bent angles were measured with a optical profile meter. Experimental results were statistically evaluated in a computer media and converted to graphics.
