With the rapid economic development, people driving comfort and safety of high demands put forward , asphalt pavement with its superior performance makes it the preferred highway , thus promoting the asphalt paver rapid development. Spiral blade as an important part of the paver , its manufacturing accuracy directly affects the quality of the road paving . With the rapid development of science and technology in order parameter , intelligent, three-dimensional as the main feature of modern CAD ??mechanical design and manufacturing has become an important tool . Based on this background , using parametric design ideas and UG software combines the development of the spiral blade parametric design system , while allowing the blade portion of multidisciplinary collaborative design in parallel , thereby shortening the design cycle of the blade . In this paper, complete the following aspects of work : 1, for the segregation phenomenon appears paving , raised through improved auger design parameters and structure to prevent the emergence of segregation . 2 to study the spiral blade feature information model, spiral blade design information and geometric information together in an organic unity . And on the basis of this model , to achieve the design of the blade design data management and preservation. Three studied UG secondary development technology, using Visual C 6.0 and database technology , the development of helical blades based on UG Parametric Design System .
