Digitization overview of production process forforging production line
Li Zhuo, Ding Xiaoyue
( Forging & Stamping Technology Center, Beijing Research Institute of Mechanical & Electrical Technology, Beijing 100083, China) Abstract: The forging production line and its digitization constitution were analyzed, and the digitization of forging production line was usually composed by the digitization on technology and equipment, process parameters, products, operation and maintenance. For the dig-itization of production process in forging production line, namely, the digitalization of process parameters, its constitution was introduced. Then, the various parameters collected in the production process were indicated, and the relationship betueen master control moms and various devices during the production process was described. Meanwhile, the brief implementation steps of the digitization of production process in forging production line were indicated, Finally, the relationship between the digitization of forging proluction line and the expert system was analyzed, and the importance of digitization of the production process in forging production line was indicated. On the one hand, it helpes to realize the transparency of production process and the traceability of product, on the other hand, it prorides data sup-ports for expert system.
Key words : forging production line; digitization; expert system; master control rooms; process parameters
对锻造行业来说,锻造生产线的数字化是指使
数字化的内涵
广义上来说,数字化是指以数字形式表示(或表现)非离散化的数据1]。具体来说,数字化是指将许多复杂多变的信息(如图像、线条、声音等)转变为可以度量的数字、数据,再以这些数字、数据建立适当的数学模型,将其转变为一系列的二进制代码,引人计算机内部,进行统一处理。数字化过程是指在计算机内部利用“0”和“1”的编码技

用“0”和“1”两位数字编码,将生产线上一切相关的设备信息,如压力、电流、故障等,及产品信息转换成数字信号,进行传输,再通过接收器使其能够在终端计算机上直观地显现出来,以便操作者能够直观地、实时地获取设备状态、生产过程进度以及质量参数等信息,实现生产的透明性和产品的可追溯性,为建造锻造生产线智能化提供数据支持。
