Die Design for automobile front cover beam front panel Based on NX

Abstract: Nowadays, people’s living standard is improving day by day and people pursue standard more and more higher .people's pursuit of the quality of life is increasing, the car as a daily necessities, people's growing demand for him. The new models continue to serving the automotive industry in recent years, The die also has been Rapid development. Domestic and foreign automotive panel mold development significantly. Features are a wide range of high-tech applications, including digital mold technology, stamping molding process simulation, high-speed processing, automated production, sheet metal stamping technology and product life cycle management technology. At present, the domestic urgent need for a large number of automotive cover mold design talent, but also on these people put forward higher requirements. This paper mainly through the design of the front cover of the car front cover of the inner part of the design, analysis and optimization of mold design structure, master the use of standard parts to understand the design principles Plastic mold with flange, reasonable stamping process design, material Performance options, Operating skills and so on. Through the study of Siemens Software Co., Ltd. UG software in the car mold-related modules to complete this graduation design.
