Rubber Extruder Screw Configuration And Automated Build System

The screw extruder plays an important role in rubber industry .The rubber screw extruder develops with the development of the screw configuration . Therefore the research on the screw configurtion is one of hot issues . Many screw configurations were analysized in this paper. The research mainly focused on how the screw configuration functions in the extruding process ; How the screw configuration impacts the extruding process was also analysized in the paper.The reseach on the screw configuration will advance and optimize screw design and it will also contribute to the developing of new type of screws. The reseach on the screw configuration is the base of developing and a CAD system for screw design . It is also the base of optimizing the function of a CAD system for screw design .Presently, the re-development of a CAD system for screw design by AutoCAD or PRO-E is mainly based on the structural program. It cann't meet diverse requirements of complex systems such as application among different processes, platforms, distributed application and reuse. To solve these problems, it is critical to select the designing pattern of a CAD system and to think about reuse capacity and extended capacity. The Component Object Models (COM) is a feasible plan that developed a CAD system for screw design. According to the characteristic of parameterized screw design, the structure of the CAD system for screw design was designed in the paper. It used Component Object Models (COM) as a unit. This method can greatly improve the efficency of development. The C++ was used as programming language and Visual C++ 6.0 was used as the platform of development for developing the CAD system for screw design. At last, the CAD system for screw design was developed on the basis of the above motheds .The CAD system for screw design was flexible for its extension and code's reuse .It can also be used for distributed application.
