Research And Development Of Progressive Die Intelligent Structural Design System For Automobile Structural Parts

The automotive structural parts of progressive die design is an important part of the process of progressive die design. Although progressive die design has a variety of styles and the correlation between step is relatively large, we still could find out similar step, in order to avoid mutual interference between the step and design the required structure staff must rely on their extensive experience in the production process design, while in the process of design, they also need consider the impact of the stripper plate and lift plate etc. This is the reasons of low efficiency of the design of progressive die design. The intelligent design system of automotive structural parts progressive die can effectively structure the required workers of this step, such as the process of forming, bending and punching, will greatly improve the efficiency of structural and reduce the costs of design.Based on the in-depth study of the progressive die design process, infrastructure characteristics and design methods, through various communication with design staff to determine the overall system of the intelligent systems and define the functions of each module. The intelligent systems include parametric technology, assembly technology and database technology, in order to achieve the punch and die assembly transfer information in a progressive die design process by use a variable associated punch and die assembly. Establishment the parametric models of each module according to their specific, establish assembly model library based on this parametric models and reuse the information of punch assembly design process, The intelligent design system of automotive structural parts progressive die was developed. In addition, intelligent introduce standard parts and design of lift plate by way of human-computer interaction that make progressive die design more efficient.According to the study, design intelligent design system of automotive structural parts progressive die based on NX platform, the design of the system for later of progressive die CAD system development provides the reference value of the research materials.
