Research And Development Of Automotive Structural Parts Of Progressive Die Process Design System

In the automotive industry, the mold is a critical part of that, nearly seventy percent of the time that corresponds to the design and manufacture of mold throughout the development process of automotive product. At present, the process design level of domestic auto progressive die structure is relatively backward, most of its design manual design using empirical, a large number of process design knowledge and process information has not been effectively utilized. Therefore, research on structural parts progressive die process design system is very necessary.For strip layout design, completed the fitting "try backtracking point by point" based on the double arc and a straight hybrid algorithm spline curve; the completion of the semi-automatic nesting and blank vector-based parametric design; complete waste of interactive design and blade knives and other functions. For strip drawing design module to complete the process to calculate the force of UDO technology-based; summing up enterprises' common mold structure diagram, through parametric techniques to build models feature enables designers to quickly generate a schematic mold and other functions. Finally tape fast detection module proposed feature recognition algorithm design process and achieve a common strip detection.Finally, on the UG platform completed in line with real business needs of automotive structural parts progressive die process design system, the system not only for the process design process was optimized, integrated process design knowledge and process information model, making the process design It has good feasibility and reliability.
