Problems solved by technology

[0003] The technical problem to be solved by the present invention is that in the existing material tensile testing equipment, with the wear and clamping failure of the jaw clamping mechanism, the reliability of the clamping will be reduced, and the process of clamping is time-consuming and laborious, which reduces the detection efficiency. At the same time, the sample to be tested is easy to splash debris after being stretched and broken, which has potential safety hazards. The purpose is to provide a test method for the mechanical properties of materials, which can not only quickly realize the clamping of materials, but also avoid the need for samples and fixtures. The wear between them improves the reliability and fastness of the clamping in the tensile test, improves the clamping efficiency in the test, and at the same time prevents the debris from flying around after the tensile fracture of the sample to be tested, improving the use of safety

Abstract

The invention discloses a material mechanical property testing method, comprising the following steps: 1) processing a material into a rod-shaped sample to be tested with trapezoidal assembly sectionsat both ends; 2) clamping the sample to be tested into a clamping device of a tensile testing machine; 3) clamping the assembly sections at both ends of the sample to be tested into a rubber fixing frame respectively, and then placing together in an accommodating groove; 4) opening two half tubes of a shielding cylinder, sleeving the part between the two half tubes with the rod section of the sample to be tested when clamping the assembly sections into a fixed block, and fastening the two half tubes to sleeve the rod section of the sample to be tested with the shielding cylinder; 5) connecting the rubber fixing frame to the tensile testing machine through a hooking thread at the end of a hook rail; and 6) starting the tensile testing machine for testing. The clamping device not only can quickly clamp materials, avoid the wear between a sample and a fixture and improve the clamping efficiency in detection, but also improves the safety of use.

Description

technical field [0001] The invention relates to a test method, in particular to a test method for the mechanical properties of materials. Background technique [0002] The tensile testing test of the material is to test the tensile strength, yield strength, elongation after fracture, reduction of area and other indicators of the material. Material sampling for tensile test is to process the sampled material into a rod shape with trapezoidal assembly sections at both ends, and assemble the material to be tested with testing equipment for testing. The assembly methods generally include threaded, clamped or suspended. In the existing material tensile testing equipment, with the wear and tear of the jaw clamping mechanism and clamping failure, the reliability of clamping will be reduced, and the process of clamping is time-consuming and laborious, which reduces the efficiency of detection and increases the detection efficiency. Risks caused by unreliable clamping during the pro...
