Quick metal material characteristic identifier system of

Abstract

The invention discloses a quick metal material characteristic identifier system, which is a quick metal material characteristic identifier system with a learning function. The quick metal material characteristic identifier system is used for detecting the metal material characteristic or the product quality by comparing the amplitude value spectrum of each material with the phase spectrum numerical value curve. The quick metal material characteristic identifier system comprises six parts such as a keyboard, a system control link, a signal generation link, a sensing link, a signal detecting link and a display link. The invention has functions of learning, storage, generation of a controllable digital frequency modulating excitation signal, outputting-inputting of relative amplitude value spectrum detection, outputting-inputting of phase difference spectrum detection and integral control and analysis to judge the material characteristic of the detected metal material or to judge whetherthe detected metal material accords with the application requirements. The quick metal material characteristic identifier system has the intelligence feature by using a single-chip as a detecting controller, has the advantages of convenience for operation of equipment, high processing speed and safety and reliability, and can be used for non-destructively detecting the metal material characteristic or judging whether the product is qualified.

Description

technical field [0001] The invention relates to a system for identifying the characteristics of metal materials, in particular to a system capable of detecting whether metal materials or finished products are consistent with the material characteristics of standard samples. Background technique [0002] The properties of metal materials are mainly divided into four properties: mechanical properties, chemical properties, physical properties, and process properties. [0003] Existing various testing equipments are used to separately test the four properties of metal materials, and most of them are destructive testing methods, and the test results can destroy the structure, characteristics and other aspects of the material. Function, so that the material can no longer be used, resulting in waste of materials; on the other hand, some products are composite structures (such as electroplating parts), and the different materials and thicknesses of each layer cannot be detected and ...

Problems solved by technology

[0003] Existing various testing equipments are used to separately test the four properties of metal materials, and most of them are destructive testing methods, and the test results can destroy the structure, characteristics and other aspects of the material. Function, so that the material can no longer be used, resulting in waste of materials; on the other hand, some products are composite structures (such as electroplating parts), and the different materials and thicknesses of each layer cannot be detected and evaluated

[0004] In terms of metal material characteristics testing, the result of each test is only a single product. To know whether the product is qualified, the quality inspection personnel need to compare the test results with the standard results, which undoubtedly reduces the efficiency and test results of product testing. the accuracy of
