A method for detecting the working state of stamping production line equipment

Abstract

The invention discloses a method for detecting the working state of equipment in a stamping production line, which includes the following steps: Step 1, collecting the oil pressure parameters F(I, T) and oil temperature parameters F(X, T) of the brakes and clutches of each unit on the stamping production line at regular intervals. ) and shock vibration parameters F(Y, T); step 2, according to the oil pressure trend identification criterion, the oil temperature increase identification criterion, and the vibration trend identification criterion, judge whether the relevant parameters collected in step 1 meet the criterion, When all are in compliance, a signal of suspected abnormality of the brake and clutch is output to remind the staff to check the stamping equipment. This method is used to determine the failure trend of the brake and clutch through the combination of abnormal conditions of multiple parameters, which is different from the traditional single parameter. The method of judging the working status of the equipment can avoid the misjudgment of the equipment caused by individual abnormal data that normally exists in the production process. Through the judgment of the equipment failure trend, the working status trend of the stamping equipment can be predicted and the equipment management can be optimized.

Description

technical field [0001] The invention belongs to the technical field of equipment detection and maintenance, and in particular relates to a method for detecting the working state of stamping production line equipment. Background technique [0002] As an important application carrier of stamping equipment, the stamping automation production line plays an extremely important role in my country's automobile industry system. However, with the improvement of production efficiency, the stamping automation production line is increasingly facing the risk of shutdown and line stop. How to efficiently control the equipment? It is imminent to reduce the downtime rate. Mastering the health status of equipment usually includes two types of predictive maintenance and preventive maintenance. Preventive maintenance is to organize maintenance plans according to a fixed period. At present, most of the maintenance plans of stamping production lines are preventive maintenance, but the maintenance...

Problems solved by technology

[0004] At present, intelligent control has been introduced into modern mechanical equipment, and the failure signal of the mechanical equipment is mostly captured to determine that the mechanical equipment has failed. However, on the one hand, the detection is based on the existence of a clear fault, and it is impossible to predict the failure trend of the production line. On the other hand, the fault signals introduced at present are often relatively single. They may be individual special case data in the normal production process, or data mutations caused by temporary changes in the environment. The above special case data or data mutations do not mean that the equipment is faulty. It is obviously not very economical and not advisable to carry out equipment maintenance for the special data brought by various emergencies in production, especially for stamping production lines with complex and numerous equipment
