1、*大学毕业设计 I 摘 要 给料装置自动化是随着现代信息技术与控制技术的进步而发展起来的， 广泛 应用于机床、矿山、冶金等行业。从以前的手工给料，到半自动化，再到自动化， 甚至智能化，给料装备发展迅猛。 本课题所改进的给料装置是应用于铸造球墨铸铁管流水线上的孕育剂的给 料装置。不同直径的管道孕育剂的需要量不同，否则会影响铸管的抗腐蚀性能和 耐用程度。目前所使用的给料装置只能给 DN300mm 的管道定量加料，而 DN1000mm的管道需要人工补料。 本设计完成了给料装置传动系统的设计与零件的校核； 基于 UG 的三维设计 与表达； PLC 的编程设计。 通过本设计实现了自动控制进料量的孕育剂自
2、动给料 装置。此装置只需要工人根据所生产的管道的直径选择选择相对应速度就可以 了，为管道质量提供了保障，同时节省了人力。 关键词：给料装置；改造设计；三维建模；强度校核 *大学毕业设计 II ABSTRACT With the development of information technology and automatic technology, the technology of automatic feeding becomes more and more mature. And now automatic feeding devices are generally used in
3、the field of machine tools、mines and metallurgical industries. From the beginning of manual feeding to the semi-automatic feeding and automatic feeding, even artificial intelligence feeding, the feeding device really made great progress. The feeding device remade in this subject operates on the pipe
4、lining of casting nodular cast iron pipe. The pipes of different caliber demand different qualities of inoculants, or this will decrease the properties of anti- corrodibility and durable performance. At the moment, the feeding device working could provide accurate inoculants for the casting of pipes
5、 in DN 300 mm while the type of DN 1000 mm needs extra inoculants by hand labor. After the whole design, the design of drive system and the calculation of components have been finished. The three-dimensional design based on UG and the designs of PLC program are also fulfilled. The design of automati
6、c feeding device has been completed. According to the caliber of the pipe, the workers can choose the right speed so that the qualities of the pipes could be warrantable.
