当前对微成形的研究主要集中在基础理论以及实验过程上,而忽略了某些和实际生产相关的关键问题。例如,一个微成形机,如果没有与之相匹配的合适的部件传送系统,就难于满足工业化生产的要求,而且很不切实际。连续的生产过程需要的不仅仅是高效率的生产设备本身,还需要与其效率和生产过程同步的材料/部件运送系统。这一系统的功能应该包括自动将成品/零件运送出成形环境并打包以便运输。文章提出了一种微型冲压成品/零件的运送策略,工作主要集中在运送设备及整个系统的研究以及设计考虑,并已应用于英国思特莱斯克莱德大学研制的一套全新的板材微成形设备上。该系统进给方法的特征以及定位精度采用有限元方法进行分析,现已构建成功,并经过了试验校准。
The current research on micro-forming mainly focuses on the basic theory and experimental process, while ignoring some of the key issues related to actual production. For example, a micro-forming machine would not be able to meet the requirements of industrialized production without the proper matching parts transfer system and would be impractical. Continuous production processes require more than just efficient production equipment itself, but also material / component delivery systems that are synchronized with their efficiency and production processes. The function of this system should include automatically transporting the finished product / part out of the forming environment and packing it for shipping. This paper presents a delivery strategy for miniature stamping of finished products / parts that focuses on the research and design considerations of shipping equipment and the entire system and has been applied to a whole new set of sheet micro-forming developed by the University of Clyde, UK Device. The characteristics of the feeding method and the positioning accuracy of the system are analyzed by the finite element method. The system has been successfully constructed and has been experimentally calibrated.
