【摘要】：超塑成形设备是实现超塑成形工艺的专用装备,加热系统作为其重要组成部分,主要起加热保温作用。随着超塑成形技术在航空航天等领域的广泛应用,对其成形设备的研究已是刻不容缓。加大对超塑成形设备加热系统关键技术及结构的研究力度具有非常现实的意义。在加热系统设计过程中,功率计算、电热元件计算和结构设计等重复性工作较多,传统的手工计算和二维制图无法适应企业高效、经济的需求,本课题将加热系统的设计过程程序化,实现参数化设计,达到缩短加热系统的设计开发周期、提高设计效率的目的。设计了超塑性成形设备的加热系统,其最高加热温度可达600°C,主要用于空间站上铝合金零件的超塑成形。对加热系统进行了加热区域尺寸确定、炉膛材料选取和炉体结构确定等工作。利用经验公式法和热平衡法分别计算了该加热系统的功率,并对加热功率的具体分配和电热元件的设计计算进行了详细的分析。完成了炉门启闭系统的设计。研究了SolidWorks三维造型软件的二次开发技术和零部件参数化设计的方法。针对加热系统产品设计的特点及其各个零件之间存在的关联设计,尤其是装配尺寸的要求,提出了符合该加热系统设计要求的参数化设计方案。利用Visual Basic 6.0作为Solid Works的开发工具,结合SolidWorks API接口函数,以超塑成形设备的加热系统为研究对象,设计参数化用户界面,建立了该加热系统的参数化设计系统,实现了加热功率和电热元件设计的自动计算以及主要零部件的参数化造型、工程图生成的自动化。完成了超塑性成形设备加热系统的主要部件制造,对加热系统的水冷板和加热板进行制造工艺设计,完成组装工作。
[Abstract]:Superplastic forming equipment is a special equipment to realize superplastic forming process. As an important part of superplastic forming equipment, heating system mainly plays the role of heat preservation. With the wide application of superplastic forming technology in aerospace and other fields. It is urgent to study its forming equipment. It is of great practical significance to study the key technology and structure of superplastic forming equipment heating system. In the process of heating system design, power calculation. The traditional manual calculation and 2D drawing can not meet the needs of high efficiency and economy, so the design process of heating system will be programmed. The parametric design is realized to shorten the design and development cycle of heating system and to improve the design efficiency. The heating system of superplastic forming equipment is designed and the maximum heating temperature can reach 600 掳C. It is mainly used in superplastic forming of aluminum alloy parts on space station. The heating area size of heating system is determined. The power of the heating system is calculated by means of empirical formula method and heat balance method respectively. The specific distribution of heating power and the design and calculation of electric heating elements are analyzed in detail. The design of the furnace door opening and closing system is completed. The secondary development technology of SolidWorks 3D modeling software and the design of the system are studied. Parametric design method of parts. According to the characteristics of product design of heating system and the related design of each part. In particular, assembly size requirements. A parameterized design scheme which meets the design requirements of the heating system is proposed. Visual Basic 6.0 is used as the development tool of Solid Works. Based on the interface function of SolidWorks API, the parameterized user interface is designed and the parameterized design system of the heating system is established by taking the heating system of superplastic forming equipment as the research object. The automatic calculation of heating power and electric heating element design, the parameterized modeling of main parts and the automation of engineering drawing generation are realized, and the main parts of heating system of superplastic forming equipment are manufactured. The water cooling plate and heating plate of heating system are designed and assembled.
