Work state detection method for punching production line equipment

Abstract

The invention discloses a work state detection method for punching production line equipment. The work state detection method includes the following steps that firstly, the oil pressure parameters F (I and T), the oil temperature parameters F (X and Y) and the impact vibration parameters F (Y and T) of brakes and clutches of all units on a punching production line are collected regularly corresponding; and secondly, whether the relevant parameters collected in the first step meet the criteria or not is judged according to the oil pressure trend recognition criterion, the oil temperature increasing recognition criterion and the vibration trend recognition criterion, and when all the relevant parameters meet the criteria, suspected abnormal signals of the brakes and the clutches are output for reminding workers to check punching equipment. By means of the method, the combination of various parameter abnormal conditions is used for determining the fault trend of the brakes and clutches, the method differs from a traditional judgment method for determining the work state of the equipment through a single parameter, the misjudgment brought by individual abnormal data normally existing in the production process to the equipment can be avoided, the work state trend of the punching equipment can be foresaw through the judgment on the equipment fault trend, and equipment management is optimized.

Description

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

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
