Steel bar cold bending test method and system and storage medium thereof

Abstract

The invention relates to a steel bar cold bending test method and system and a storage medium thereof. The steel bar cold bending test method comprises the following steps: equipment instialization: the test frequency, a test list and test duration are initialized and set, and the test list comprises the test material diameter of multiple tests, errors before the tests and test time consumption, wherein the test duration is the total use duration after equipment initialization; the reflective images of the surface of the cold bend and the surface of the die holder are captured, and cold bend loss is calculated; before the test, the current loss error is calculated, and the current loss error = cold bending loss * test time consumption / test duration; a zero setting equipment inputs the diameter of the current test material and calculates the current test error, and the current test error is equal to the product of the current loss error and the previous test material diameter of the current test material; and the test material is tested to obtain current measured data, and compensating the measured data = (1 + current test error) * the current measured data. The method has the effect of enabling the equipment to be easily and accurately corrected.

Description

technical field [0001] The present application relates to the field of steel bar testing, in particular to a steel bar cold bending test method, system and storage medium thereof. Background technique [0002] At present, in the test of building materials, the steel bar test is an indispensable one, because the quality of the steel bar determines the quality of the construction. Now the cold bending test is used to test the steel bar, and the steel bar is evaluated by checking the technological performance of the steel bar. the quality of. [0003] The cold bending test is to use the cold bending head and the mold base to adopt the bending method or folding bending. Under the condition of gradually reducing the arc surface radius R of the punch, the minimum bending radius Rmin when the outer material of the sample does not produce cracks is determined. The ratio of it to the basic thickness T of the sample, that is, the minimum relative bending radius Rmin / T0, is used as th...
