Minimizing Springback of Steel Strips in V-Die Bending Using Numerical Simulation and Optimizing Parameters
Abstract

Springback (SB) is generally noticed in bending operation of ductile materials. This is due to the elastic recovery of the material after obtaining certain plastic state, and can be determined by material loading history. SB impacts the final accuracy and shape of products. The present study employed finite element analysis (FEA) simulation of punching operation of plate to a V-block with different process parameters. Stainless steel (SS) strips were used for bending operations. SB was calculated numerically from FEA analysis, and the results were compared with experimental data. Different parameters were taken into consideration for SS in ANOVA, and it was observed that plate thickness and punch radius were the two important parameters that affect SB the most. After finding the optimized parameter, a new die punch system was designed so that SB was minimized.

Introduction

The forming process of sheet metals is very useful in almost every stage of production in industries like automotive, aerospace, home appliance, construction, food container, etc. Sheet metal works majorly in sheet metal bending.
