【摘要】：由于铸造质量影响因素的多样性、生产过程控制的复杂性,现阶段通过合理组织、加工处理、统计分析历史生产数据来推进工艺改进、技术培训和生产控制,最终实现铸造缺陷的有效防治仍具有重要作用,但是以往大量的相关专家知识和经验数据并未得到有效的积累、集成和分享再利用。本文在对九大类180余种铸造缺陷分类与编码的前提下,建设了包括缺陷标准库、案例分析库、典型图片库和不良品库在内的铸造缺陷数据库,目前已在某研究所和国内某柴油发动机厂铸造事业部上线应用,并取得了良好的效果。应用表明:该数据库适用于多生产线类型铸造企业缺陷识别和管理标准的建立、经验案例和典型图片的积累,以及不良品缺陷的统计分析,有助于推进行业内铸造工艺基础数据库的全面建设。
[Abstract]:Due to the diversity of factors affecting casting quality and the complexity of production process control, at this stage, through rational organization, processing, statistical analysis of historical production data to promote technological improvement, technical training and production control, It is still important to realize the effective prevention and cure of casting defects, but a large number of related expert knowledge and experience data have not been effectively accumulated, integrated and shared and reused in the past. On the premise of classifying and coding more than 180 kinds of casting defects in nine categories, this paper has constructed the foundry defect database including defect standard database, case analysis database, typical picture database and bad product database. It has been applied in the foundry department of a research institute and a diesel engine factory in China, and good results have been obtained. The application shows that the database is suitable for the establishment of defect identification and management standards for multi-production line foundry enterprises, the accumulation of experience cases and typical pictures, and the statistical analysis of defective products. It is helpful to promote the comprehensive construction of foundry technology foundation database in the industry.
