In the rubber industry, screw rubber extruder is very important processing equipment. The screw extruder is developed with the development of its core component-the configuration of the extrusion screw, so the study of the screw configuration is one of the hotspots in the study of screw extruders. Based on the analysis of the structural characteristics of various screws, this thesis conducts a theoretical analysis of the screw configuration. The extrusion mechanism, main functions, advantages and disadvantages of various screw configurations are analyzed; the influence of various screw configurations on the extrusion process is analyzed.
Studying the working principles of different configuration screws and their influence on the extrusion process will surely be beneficial to the further optimization of the screw structure design and the development of new types of screws, thereby benefiting the development of the rubber industry; and the structural characteristics of different configuration screws Research is the basis for the development of a CAD system for rubber screws. It is also the basis for optimizing the design functions of the CAD system for rubber screws. At present, the special CAD for rubber machinery mostly adopts some simple secondary development on AutoCAD or PRO-E. This kind of development is based on a structured basis. Not only is the reusability very poor and cannot be developed in depth, but it is also difficult to meet the complexity The diversified needs of the system make it difficult to expand and reuse, and it is also difficult to solve the problems of cross-process, cross-platform transplantation and distributed application in the design of rubber machinery special CAD system. To solve these problems, the selection of system design patterns and the reusability and scalability of the system have become the key to system design. At present, a variety of design patterns can be used to cleverly reuse software objects and design the system structure of the software from the top-level perspective; the COM-based component object model can fully realize the compatibility of multiple forms based on the binary executable code level. Reuse well. The COM-based component object model is a "feasible road" to realize the rubber-specific CAD system. Based on the research of different screw configurations, this paper uses C++ object-oriented development language based on the characteristics of the CAD parameterized design of the rubber extruder screw, and uses the COM component as the functional unit to automatically generate the rubber extruder screw System structure design, the system can easily realize future expansion and code reuse and be used to realize distributed applications, which greatly improves development efficiency. Finally, on the Visual C++ 6.0 development platform, under the guidance of the "feasible road" thought, the development of the COM-based "rubber screw automatic generation system" was completed.
