Abstract

The invention discloses a method for diagnosing the mold state of a fastener forming machine, comprising: acquiring sample pressure sensing data when the fastener forming machine and a sample mold process a sample workpiece. A mold state definition step is performed to obtain a plurality of mold states corresponding to the sample pressure sensing data. Using the sample pressure sensing data and establishing an encoding model according to an automatic encoding algorithm, the encoding model compresses each group of sample pressure sensing data into an array sample encoding feature. A mold state prediction model is built using sample encoded features and their corresponding mold states. The target workpiece is processed using the fastener forming machine and the target tooling to obtain target pressure sensing data. The target pressure sensing data is input into the encoding model to obtain a set of target encoding features. Input the coded features of the target into the predictive model, and estimate the predicted mold state of the target mold. Thereby, the abnormal state of the fastener forming machine can be detected in advance.

Description

technical field [0001] The invention relates to a method for diagnosing the state of a mold, and in particular to a method for diagnosing the state of a mold for a fastener forming machine. Background technique [0002] In order to solve the problem that the processing machine cannot immediately detect the processing quality during the processing process, the existing method is to use a prediction system to predict the processing quality during the processing operation of the processing machine. [0003] However, different processing machines have different operation modes and processing methods. How to find out the key features that affect the processing quality of the fastener forming machine as the input value of the prediction system, so as to achieve the goal of predicting the processing quality has become the goal of the relevant industry. . Contents of the invention [0004] Therefore, an object of the present invention is to provide a method for diagnosing the mol...
