Abstract

The invention discloses a clamping method used in metal material mechanical property test. The clamping method comprises the following steps: 1) processing a material into a rod-shaped sample to be tested with trapezoidal assembly sections at 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 the assembly sections and the rubber fixing frame together as a whole body in an accommodating groove, wherein the rod section of the sample to be tested is clamped into a sample notch, and a hook rail on the rubber fixing frame is clamped in a hook rail notch; and 4) connecting the rubber fixing frame to the tensile testing machine through a hooking thread at the end of the hook rail. The clamping method can quickly clamp materials, avoid the wear between a sample and a fixture, improve the clamping reliability and tightness in tensile test, and enhance the clamping efficiency in test.

Description

technical field [0001] The invention relates to a clamping and clamping method, in particular to a clamping method for testing the mechanical properties of metal 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. The risk brough...
