Hardness testing method based on integrated terminal application

Abstract

The hardness detection method based on the integrated terminal application disclosed by the present invention is provided with an integrated terminal machine, including a measuring head, a camera, a camera sensor component and a data processor; the terminal machine is turned on, and the measuring head is placed on the test sample and start to load the detection force; the camera shoots and acquires the indentation image, and sends the indentation image back to the data processor through the camera sensor component; the detection force preset is loaded and enters the saturation The loading stage; the full loading stage is completed, the measuring head returns to its position, and the camera sensor stops working synchronously; the data processor performs data processing on the transmitted image to calculate the hardness value of the sample. This method effectively applies an integrated portable device, which is convenient for measuring the hardness of metals of different sizes, volumes or shapes, and the data processing and image processing processes are realized simultaneously, which effectively shortens the measurement time, shortens the measurement cycle, and improves efficiency.

Description

technical field [0001] The invention relates to metal hardness testing technology, in particular to a hardness testing method based on an integrated terminal application. Background technique [0002] Hardness is one of the most commonly used indicators to evaluate the mechanical properties of metal materials. The essence of hardness is the ability of a material to resist the intrusion of another harder material. For the tested material, hardness represents the comprehensive performance of various physical quantities such as elasticity, plasticity, strength, toughness and wear resistance reflected under a certain indenter and test force. Since the hardness test can reflect the performance difference of metal materials under different chemical composition, structure and heat treatment process conditions, the hardness test is widely used in the inspection of metal properties, supervision of heat treatment process quality and development of new materials. [0003] The testing...

Problems solved by technology

[0003] The testing equipment used in the traditional hardness testing method is large in size, not easy to carry, and cannot meet the product testing in different scenarios or special environments. In particular, the design of the measuring equipment itself limits the volume or size of the measured item. Specific metal products within the scope greatly limit its detection requirements, and the traditional detection method is distributed in the acquisition of indentation images, data conversion and later data processing, which requires a long detection time
