Aluminum Extrusion Mold Computer-aided Design

In modern industry and life, Aluminum profiles are used more and more widely now. Extrusion plays an important part in A-alloy industrial system. Along with the advancement of science and the development of national economy, users have new requirement in precision, figure and surface finish quality of A-alloy product.In development of Aluminum profiles, the technology of extrusion is relatively perfect. But the design experience still trails the development of extruding Most mould design depends on estimation, gnosis, and experience of the designer, prototype is necessary.Using Computer Aided Design, the periods of mould design and making can be shortened, the times of mould shakedown test can be reduced, the labor capacity can be improved, and the cost of mould can be reduced consumedly. With the man-machine interactive system, specialized knowledge and data stored in computer the quality, efficiency and economy of mould making can be assured.This paper induces the primary sort of Aluminum profile and Aluminum extrusion die, introduces the main characteristic of Aluminum profile extrusion technics, summarize the chief experience principle of craft and structure design.On base of mastering Aluminum profile extrusion craft, the author parameterize the structure and craft of extrusion die. This is also the base of CAD. The separation of man-machine interactive system and model building system can solve the difficulty in model modify.The paper do its best in decreasing the number of parameter, in order to ensure the consistency, repeatability and accuracy of mould making; Under the premise of of making the most of original resource of Unigraphics. The paper has developed the interface of man-machine interactive system and the Aluminum profile cross section information. The data file as the pathway of man-machine interactive system and model building system is arranged. During die bearing design, the designer's personal energy can be mostly brought into play.Using the software package of UG/Open GRIP, automatic model building...
