Abstract

The invention discloses a die state diagnosis method of a fastener forming machine. The die state diagnosis method comprises the following steps: acquiring sample pressure sensing data when the fastener forming machine and a sample die process a sample workpiece; performing a die state definition step to obtain a plurality of die states corresponding to the sample pressure sensing data; using thesample pressure sensing data and establishing a coding model according to an automatic coding algorithm, wherein the coding model compresses each group of sample pressure sensing data into array sample coding features; establishing a die state prediction model by using the sample coding features and the corresponding die states; processing a target workpiece by using a fastener forming machine anda target die to obtain target pressure sensing data; inputting the target pressure sensing data to the coding model to obtain a group of target coding features; and inputting the coding features of atarget to the prediction model, and estimating the predicted die state of the target die. Therefore, 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 workshops. 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 prediction of processing quality has become the endeavor of the relevant industry. Target. Contents of the invention [0004] Therefore, an object of the present invention is to provide a method for diagnosing the ...
