Design and Optimization process of press tools using Forming analysis for Frame Bonnet Front Automobile Panel

Abstract

This paper highlights the springback compensation of frame bonnet front automobile part by using simulation tools. Frame Bonnet Front has more spring back than typical steel, affecting the end part's dimensional correctness. While stamping a sheet metal component, spring back compensation is a significant difficulty. Spring back is the geometric change that occurs when a part is freed from the tool press. Springback is caused by the elastic release from the bending stress given to the sheet metal during forming. By using over bending technique, the material is bent beyond its intended angle, allowing the springback to return it to the intended angle. The over bending compensation value can be carried out with the help of simulation. The compensation values from simulation applied to practical bending process. The final results of the part on the inspection fixture were within the allowed tolerance. Toolmaker can save a lot of time and money by using simulation for springback in their engineering and testing.
