基于Pro/E的压机中气液联动冲压系统的设计与研究
|
摘要
冲压系统是玻璃器皿压机成型玻璃器皿的关键子机构,本文结合天津市重点科技攻关项目“智能化异形玻璃器皿开模压机的研制”,针对气动冲压系统的缺点,设计并实际应用了一套新型的玻璃器皿压机气液联动冲压系统来代替它。由于气动技术有传输快、无污染和介质易获取等优点,所以使得气动技术能与其他传动方式相结合,包括与液压传动的结合。本文称这种传统的气压与液压相结合的传动系统及控制系统为气液联动系统。与气压传动系统相比,它具有运转平稳,调速效果良好,工作可靠的特点。与液压传动系统相比,它污染相对较小,经济性好,制造维修方便。因此,与国产其它压机相比,在工作过程中,该机的气液联动冲压系统工作平稳,噪音和振动显著减小,也使产品合格率有所提高。
本文详细介绍了气液联动冲压系统的设计计算过程、组成、原理及设计方案的确定。该冲压系统结合了液压与气动各自的优势,并且巧用了自行改装的气控液压换向阀和液控单向阀。总体上讲,整个冲压系统具有简单、节能、高效、低污和低噪等一系列优点,提高了玻璃器皿压机的综合性能,实现了其具备自动化程度较高的机、电、气、液一体化控制系统。
接着运用虚拟设计技术、模块化设计方法、参数化设计方法和自顶向下技术深入研究了全新的气液联动冲压系统,并在Pro/E下进行二次开发,开发出玻璃器皿压机气液联动冲压系统CAD系统,改变了传统的二维设计方式,实现了智能化的自动设计,提高了设计效率和设计质量,缩短了产品设计制造周期,降低了设计成本。
运用流行的设计软件Pro/E对气液联动冲压系统进行概念设计、实体建模和虚拟装配,建立了虚拟样机,同时建立了气液联动冲压系统二次开发的系统框架和参数化模型库;在Access 2003下建立了气液联动冲压系统的参数化设计数据库;结合Pro/TOOLKIT和Visual C++编写了系统应用程序,实现了人机交互界面,为今后的玻璃器皿压机整机参数化奠定了基础。
最后通过Pro/TOOLKIT接口程序设计以及ODBC技术实现了MFC与Access 2003的连接,实现了各个应用程序模块、数据库模块和Pro/E系统的无缝集成,建立了玻璃器皿压机CAD系统的子机构模块系统——气液联动冲压系统CAD系统。
The key component of glassware press machine is press system which helps the glassware's mold. New press system with Pneumo-Hydraulic system is designed and used because of shortcomings of press system with pneumatic system in glassware press machine. It's integrated with the item of Tianjin government which is called "The research of new style of glassware press machine". Pneumatic technology has some advantages: fast transmission, no pollution and getting easy, so it works easily with other ways including hydraulic technology. It's called Pneumo-Hydraulic system that traditional pneumatic technology and hydraulic technology work together. It operates more steadily, shifts better and works more reliably than pneumatic. It has less pollution, better economy and easier making than hydraulic. Therefore, it works more steadily, reduces noise and libration and improves qualified rate of production in the process of working.
In this thesis, design calculation, composing, principle and design scheme of press system with Pneumo-Hydraulic system are introduced particularly. There are hydraulic directional valve with pneumatic control and check valve with hydraulic control in it. It's integrated with advantages of both pneumatic and hydraulic. In a word, it has some advantages: simpleness, energy conservation, high effect, light pollution and low noise. It improves integrated capability of glassware press machine and comes ture high roboticized control system which is composed of machine, electricity, pneumatic and hydraulic.
And then we study it by dummy design technology, modular design technology, parameterized design technology and top-down technology. We develop CAD system of it based on Pro/E, so traditional 2D design is changed, intellectualized automation design is achieved, the design efficiency and design quality are improved, the developing cycle of product is shortened and the design cost is reduced.
Concept design, entity modeling, dummy assembly, establishing dummy machine of it are made by using popular Pro/E. In the meanwhile, the structure of CAD system of it and parameterized parts database are established by Pro/E. Parameterized design database of it is established by using Access 2003. The application program of this system compiled by using Pro/TOOLKIT and Visual C++ makes the friendly interface come true. Actually, those are in favor of developing the whole of glassware press machine CAD system.
Finally, CAD system of it which is a part of glassware press machine CAD system is set up by realizing the seamless integration among every application module, database module and Pro/E system through Pro/TOOLKIT interface program design and ODBC which is the technology about integrating between MFC and Access.
