Description

Technical Field

[0001] The utility model relates to the technical field of force value calibration of a tensile testing machine, in particular to an imported high-temperature tensile testing machine with an integrated force value calibration function. Background Art

[0002] In the field of materials science and engineering, the high-speed tensile testing machine is one of the key equipment for testing the tensile properties of materials. It simulates the stress conditions of the material in actual use by stretching the material at high speed, thereby evaluating the mechanical properties of the material such as strength and toughness. However, since the force value drift caused by factors such as wear and temperature changes may occur in the long-term use of the testing machine, it is particularly important to regularly calibrate the force value of the high-speed tensile testing machine. At present, the main method for calibrating the force value of the high-speed tensile testing machine is to use a standard dynamometer. The standard dynamometer is a high-precision measuring device with stable measurement performance and reliable accuracy, and can be used as a benchmark for calibrating other force measuring equipment. By comparing the force value of the high-speed tensile testing machine under test with the force value of the standard dynamometer, it is possible to accurately determine whether the force value of the testing machine is accurate, and thus make corresponding adjustments;

[0003] However, the traditional calibration method has some shortcomings. First, due to the large range of the high-speed tensile testing machine, calibration is required at different force points, which increases the complexity and workload of calibration. Secondly, the traditional calibration method often requires multiple pre-tensioning on the testing machine to ensure the stability and accuracy of the testing machine, which further increases the time and cost of calibration. Therefore, we proposed an imported high-temperature tensile testing machine with integrated force calibration function to solve the above problems. Utility Model Content
