|
摘要
随着汽车工业快速发展,轮胎企业对模具的精度、质量、寿命以及交货期的要求越来越高,模具企业之间的竞争也在加剧。目前国内轮胎模具生产能力,特别是子午线轮胎活络模具生产能力严重不足,这是橡胶轮胎模具行业面临的一大问题。
本论文主要研究16等份子午线轮胎模具的加工流程及CAD/CAM一体化技术的实现过程。本课题将综合利用模具制造与构造技术、模具制造工艺学、模具CAD/CAM技术等成果来研究子午线轮胎模具的生产流程、NC加工时刀具选取、走刀路径规划、切削用量参数选择等技术,保证在满足加工精度要求的情况下提高加工效率。
本论文针对子午线轮胎活络模模具的加工工艺与流程分析、电火花加工子午线轮胎活络模具型腔技术,以及轮胎模具石墨电极的CAD/CAM技术等开展较系统的研究工作,并取得了一些创新成果。
针对传统加工轮胎模具的加工工艺存在的问题,以及对子午线轮胎模具加工工艺的分析,提出了两种加工方案,并通过项目的可行性分析,选择了第一种方案。
采用电火花成型加工方法加工子午线轮胎活络模具的型腔及花纹,加工型腔过程中主要问题是电极的加工以及夹具的结构选择。应用CAD/CAM软件,完成石墨电极的三维造型,同时利用CAM功能执行后处理生成刀具的加工路径,并生成NC程序以及进行仿真加工。完成轮胎模具的数控代码DNC传输的软硬件配置及对应关键部件模具的数控加工。
With the rapid development of automobile industry,Tire business has increasingly higher demand for the precision,quality,life expectancy,as well as delivery of the mold,The competition among mold business has also increased.Current domestic production capacity of tire mold,especially the Segment Mould of meridian tyre production capacity of a serious shortage of active mold,This is a major problem of rubber tire mold industry is now facing.
In this paper,The main problem is the analysis on the process flow and the research of CAD/CAM technology on the ZG88′H680-16 share of the Segment Mould of meridian tyre.One of the Segment Mould of meridian tyre has the highest technical content,the difficulty of the highest and the best development prospects.At present,there is only 10 more than the national can produce this type of mold. Application of this tire mold of traditional manufacturing methods is very difficult,long cycle and it is difficult to guarantee the accuracy,So its difficult to meet the growing demands of the market.CAD/CAE /CAM technology to become widely used tire mold production efficiency and improve the quality of an effective way.
In this paper,the Segment Mould of meridian tyre mold flow analysis and processing,EDM mold cavity active radial tire technology,tire molds,as well as graphite electrodes CAD/CAM technology to carry out a more systematic research and innovation have made some.
Tire mold for traditional processing technology of processing problems,as well as the tire mold process analysis,we propose two processing program,and project feasibility analysis,select the first option.
EDM processing methods used tire processing die cavity and the active pattern,processing cavity are the main issues during the processing electrode and the structure of fixture selection.Application of CAD/ CAM software,to complete the three-dimensional modeling of graphite electrode,the use of CAM function at the same time after the implementation of the treatment process to generate tool path,and generate and simulate NC machining process.Tire mold finish DNC CNC code transmission and the corresponding hardware and software configuration of key components of the NC machining tool.
