Abstract

The invention aims to provide a diagnosis device, a diagnosis method, a storage medium and a computer device capable of improving the abnormality type judgment precision of a punching device. A press device is a device for performing press processing, and the press device deforms a raw material by bringing a cutter into contact with the raw material by pressure. The diagnosis device is used for diagnosing the state of the stamping device. The punching device is provided with a generation unit for generating a spectrum based on a vibration waveform indicating the vibration of the punching device over time. And a determination unit that determines the type of abnormality of the press device on the basis of a characteristic of the spectrum corresponding to vibration of the press device occurring at a predetermined time during the implementation of the press process.

Description

technical field [0001] The present invention relates to a diagnosis device, a diagnosis method, a storage medium and a computer device. Background technique [0002] The stamping device is used to press the tool into contact with the raw material to deform the raw material for stamping. Existing technology can detect anomalies in stamping devices. For example, Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2004-358487) discloses a technique for detecting an abnormality based on elastic waves detected by an AE (Acoustic Emission) sensor in each process. [0003] There are various types of anomalies that can occur in the stamping unit. When judging the type of abnormality, if the method of detecting the abnormality from the characteristics of the elastic wave is adopted like the conventional technique, the type of the abnormality may not be correctly judged. [0004] In view of the above problems, the present invention aims to provide a diagnostic...
