Research And Application Of Parametric Modeling Technique For BAOSTEEL ERW610 Forming Mill

As a kind of main product of secondary processing of strip steel, longitudinal welded pipe has many advantages such as low energy-consuming, high-precision, high-productivity compared with seamless pipe. With the development of welding process, prototyping technology, quality detection and control technology, welded pipe becomes more and more qualified. On the other hand, due to the attention to environment protection and energy of human beings, welded pipe is being widely used in many department of our economy replacing seamless pipe. Because of the complex and hard-manipulative process of welded pipe, modern design method such as CAD/CAE/CAM is used for developing research job of related prototyping technologies of ERW (Electrical Resistance Welding). The result of this research will greatly push the further development of the quality of welded pipe.On the basis of review and analysis of roll CAD technology, mill of ERW610 which imported by BAOSTEEL in 2005 is taken as background in this paper. The key technologies and realizable methods of parametric modeling are detailedly investigated in this paper.KBE (Knowledge Based Engineering) technology and the objected-oriented idea are applied in the parametric modeling system of ERW610 mill. This paper analyzes the necessity, characters and thought of Knowledge-Based parametric modeling and put forward its key problem: knowledge acquisition, knowledge representation and knowledge application during the course of modeling.Studying on the technology of parametric modeling includes: UG secondary development, UG/KF (Knowledge Fusion) and database system. Building the framework of system based UG platform; Using KF knowledge to build engineering rules and relating them to product geometrical model, realizing alteration of every module by illustrating...
