【摘要】：目前市场上托辊的加工设备有很多,但大部分都是手工操作的单机,这种传统的手工操作工作量大、慢、容易出错,已不能适应现在快速变化的市场。国内的托辊生产线基本都是半自动化的模式,即把加工设备按照工艺流程的位置摆放,然后由人工操作机床,上下料靠吊车或者手动完成。国外的托辊生产技术发展较快,生产线的自动化程度非常高,但是进口的托辊生产线的价格非常昂贵,而且后期的维护维修也十分困难,只有国内极少数的企业引进了国外的托辊生产线,因此开发适合我国国情的托辊自动化生产线具有重大意义。TG-ZX01托辊加工及装配自动化生产线是国内第一条自主研发的托辊加工及装配自动化生产线,全线实现加工装配自动化、工件输送自动化及调整自动化,是具有高科技含量的柔性化的加工生产自动线。本文研究TG-ZX01托辊加工及装配自动化生产线主要从以下几个方面进行：(1)分析对比了国内外托辊生产设备的现状以及发展趋势。(2)介绍钢制托辊的结构、分类、用途以及加工装配要求。(3)结合目前钢制托辊的生产加工工艺,总结了一套新的托辊工艺流程,并据此工艺流程设计出生产线总体方案,确定生产线布局,并对生产线进行了平衡设计。通过平衡的设计可以促进整个生产系统的人员配置,物流运输,信息传递更加顺畅,降低了人员,物流的成本,提高整条生产线空间和时间的利用率,提高了整个生产过程的生产效率,帮助企业降低成本,提高整体生产效益。(4)对生产线采用的新技术新工艺进行研究分析,对生产线生产的托辊进行精度分析。论文在分析托辊各部分结构的基础上,总结了托辊各部件加工以及整体装配的要求,对各工序加工分别提出了工艺改进与设计分析。并综合了目前加工托辊设备的研究成果,将独创的托辊卡圈压装技术、轴承座无止口压装工艺、精度综合检测技术等应用到生产线中。最终研制开发出一条全自动化的托辊加工与装配生产线。该项目是国家的重点项目,获得了国家的首台套认证,并已交付用户使用,生产线生产的托辊各项指标均达到国家标准GB1059-89的规定,满足了用户的要求,给用户带来了巨大的经济收益和社会效益。
[Abstract]:At present, there are a lot of processing equipments of roller in the market, but most of them are single machines operated by hand. This kind of traditional manual operation is heavy, slow and error-prone, so it can not adapt to the rapidly changing market now. The domestic roller production line is basically semi-automatic, that is, the processing equipment is placed in accordance with the technological process, and then manually operated machine tools, loading and unloading by crane or manual completion. Overseas roller production technology is developing rapidly, and the automation of production line is very high, but the price of imported roller production line is very expensive, and the maintenance and maintenance of the later stage is very difficult. Only a very small number of domestic enterprises have introduced overseas roller production lines. Therefore, it is of great significance to develop the automatic production line of roller for our country. TG-ZX01 automatic production line of roller processing and assembly is the first automatic production line of roller processing and assembly developed independently in China, and the whole line realizes the automation of processing and assembly. Workpiece transportation automation and adjustment automation is a flexible automatic line of processing and production with high-tech content. This paper studies the automatic production line of TG-ZX01 roller processing and assembly mainly from the following aspects: (1) the present situation and development trend of domestic and foreign roller production equipment are analyzed and compared. (2) the structure and classification of steel roller are introduced. Application and assembly requirements. (3) combined with the current production and processing technology of steel rollers, a new process of roller is summarized, and the overall production line scheme is designed according to the technological process, and the layout of production line is determined. The balance design of the production line is also carried out. Through balanced design, it can promote the staffing of the whole production system, logistics transportation, information transmission more smooth, reduce the cost of personnel, logistics, improve the overall production line space and time utilization, It improves the production efficiency of the whole production process, helps the enterprise to reduce the cost, and improves the overall production efficiency. (4) the new technology and new technology used in the production line are studied and analyzed, and the precision of the rollers produced in the production line is analyzed. On the basis of analyzing the structure of each part of the roller, this paper summarizes the requirements of the parts processing and the whole assembly of the roller, and puts forward the process improvement and design analysis for each working procedure. Based on the research results of the current processing roller equipment, the original roller card ring pressing technology, bearing non-stop pressing technology, precision comprehensive testing technology and so on are applied to the production line. Finally, a fully automatic production line of roller machining and assembly is developed. The project is one of the key projects in the country. It has obtained the first set of certification of the country, and has been delivered to the users for use. All the indicators of the rollers produced in the production line meet the requirements of the national standard GB1059-89 and meet the requirements of the users. It brings huge economic and social benefits to users.
