Based DANAFORM Typical Automobile Panel Parts Of The Forming Process

With the continuous development of the automotive industry, vehicle body development is focused on performance, quality, economic, beautiful and comfortable and safe and reliable. If you want to lighten the weight, you must use a thin high strength material or increase the number of reinforcing decorative reinforcement, in order to increase the corrosion resistance, we must use corrosion resistant material or coating material, in order to streamline, appearance, often very complex, which will increase the difficulty of parts drawing. For a more complex structure of the drawing, in the past completely rely on the designer’s experience and analogy method to design process and die, die stamping and commissioning test of validation of the various quality issues, such as rupture, wrinkling, less rigid, resilient too large, thinning of the material and so on, the first stamping condition adjustment, again on the mold for repeated correction. If the designer’s lack of experience or parts of very irregular shape, repeated correction will be ineffective, causing mold scrapped. This not only affects the production cycle, and increase the cost of. Therefore, the traditional" trial and error" method has been unable to meet the pace of the upgrading of products.The subject of the use of DYNAFORM in this industry general finite element analysis software as a tool, the main research work carried out are:analysis of some typical covering parts of edge beams, door hinge reinforcing plate, vertical column, the reinforcing plate of the binder and addendum design, at the same time, some parts of the drawing numerical simulation of the forming process, and in the follow-up to its forming simulation, using in site technical prediction process of forming defects, by repeatedly simulating optimization of forming process, ultimately to eliminate defects. Field trial and error debugging using software simulation analysis of alternative. The parts stamping process based on the analysis of the drawing process, the possible process are compared and analyzed, obtained preliminary feasible process plan. According to the results of numerical simulation, optimization of drawing process technology program. And through the actual production of its validity for practical testing.Through the study of this subject, will be based on numerical simulation analysis method in the automobile panel drawing process optimization applications provide successful application examples and experience, for further study of guiding effect. Hope to collect relevant technical parameters, to improve the current job complexity.
