Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] This measuring table meets the following production conditions: plate thickness: 0.2-5mm, width: 12.5-25mm.

[0024] Calibration method implementation of the cross-section measuring bench:

[0025] see figure 1 , firstly, the standard sample 2 is sent to the calibration station, and the calibration value is obtained after measuring the standard sample 2;

[0026] The specific process is: a pair of displacement gauges (the first displacement gauge 1.1 and the third displacement gauge 1.3) facing each other in the thickness direction respectively measure the thickness of the standard sample 2 to obtain the calibrated thickness value A1; A pair of displacement gauges (the second displacement gauge 1.2 and the fourth displacement gauge 1.4) measure the width of the standard sample 2 and obtain the fixed value of the calibration width A2;

Abstract

The invention relates to a calibration and inspection method for a cross-section measuring platform, which is characterized in that: when calibrating, the standard sample is put into the calibration station, and then the displacement gauge is stretched out to measure the standard sample to obtain a calibration value; then, the displacement gauge is stretched out Measure the cross-section to obtain the cross-section measurement value; finally, compare the cross-section measurement value with the actual size of the standard sample to determine whether the cross-section measurement system is accurate. The method is accurate and convenient, and ensures the automatic measurement of the cross-sectional area and the realization of the automatic stretching process.

Description

technical field [0001] The invention belongs to the field of detection of mechanical properties of thin plate materials, and in particular relates to measuring the cross-sectional dimension of a sample in a fully automatic tensile test process for thin steel plates such as galvanized steel sheets, in order to ensure the accuracy of cross-sectional dimension measurement. Methods for calibration and verification of cross-section measuring devices. Background technique [0002] The mechanical performance index of the steel plate is a direct response to the performance of the steel plate, and the acquisition of important mechanical indexes such as yield strength and tensile strength must be based on accurate cross-sectional measurement data. How to ensure the stability and reliability of the cross-section measurement system is a necessary guarantee to realize the automatic tensile test process. [0003] At present, the equipment for testing the mechanical properties of thin pla...
