Abstract：

In order to improve the fault diagnosis efficiency of press in the field of metal stamping, a real-time self-diagnostic method of press fault was proposed to determine the fault points of press by combining various press information. Firstly, the diagnostic system obtained the information about the current operating state of press from the control system. Then, the reasoning machine combined the various types of information threshold and statuses for data analysis and performed fault reasoning matching based on the data analysis results and the fault phenomenon descriptions to find possible fault points. At the same time, the potential faults of press were diagnosed by multi-dimensional data. Finally, the faults were processed according to the diagnostic result and fed back to the diagnostic system, and the diagnostic system database was updated based on the feedback maintenance. Therefore, the practical application on press show that the above real-time self-diagnostion of fault can locate the fault points quickly, shorten the fault processing time and improve the production efficiency.
