Finite Element Simulation And Optimization Of Stainless Steel Rectangular Box Drawing And Forming

The sheet metal is the most common materials in the manufacturing industry, the mainprocessing mode is stamping. Stamping has become an important processing technology inmanufacturing technology by right of fast forming speed, highly product efficiency, highlymaterial utilization, and also widely used in the field of automotive, aerospace, electronic area,electrical appliance, daily-use hardware, etc. And even can be said, stamping technology andequipment level are important symbols to measure a country’s manufacturing level, and alsodetermine national manufacturing industry international competition ability.Stamping is a large deflection and deformation process, in the actual process, it’s difficultto make a reasonable prediction for the material formability with pre-experience. Sonowadays material stamping, use the advanced computer-aided (CAE) analysis techniques tosimulate the actual stamping concrete parts, this techniques has become a major researchmethod.Nowadays DYNAFORM is the more mature CAE analysis software, use the dynaformsoftware in this paper, take the most common304stainless steel sink as a research model,finite element analysis of rectangular box drawing process, simulated process which found theproblems in the stamping, and modified the mold design or stamping technics, and then putup multiple cycles of simulation, ultimately optimization of the various parameters tothe pattern and molding process. This kind of finite element analysis and simulationtechnology can find variety problems and make improvement in the early mold design stage,in this way can shorten the development cycle of new products, reduce development costs,improve product quality and enhance competitiveness in the market, so this method has astrong enterprise practical application and popularization meaning.
