Exploration of Springback Prediction System of Sheet Metal on Refrigerator Door and its Die Design

Abstract

To be faced with the appearance and mechanical defects during refrigerator door making process, enterprises have no effective solutions. A springback prediction system is developed to accurately predict the springback of sheet metal and to improve die design. The main components, key theory and technique of this system are illustrated for the purpose of revealing co-relationship of springback and constitutive model and different parameters. It provides a powerful tool for cutting production cost and raising working efficiency. It is of great significence for engineers and enterprises.
