Embodiment
[0021]Example: When in use, first clamp the metal rod between a pair of hydraulic fixing clamps 19, and then pass the heat transfer oil into the box 1, and the liquid level of the heat transfer oil is located between the filter screen 7 and the air outlet pipe 6. position, and then start the electric heating plate 9 to heat the heat transfer oil, the heat transfer oil will heat the metal rod, then start the hydraulic cylinder 4, and perform a tensile test on the metal rod, which can be carried out under the same tensile force at different temperatures or at the same temperature For tests of different tensile forces, when it is necessary to test the tensile properties of the coking metal, air is fed to the top of the liquid surface through the air pump 2, the valve is opened to make the air above the liquid surface in a state of circulation, and then the electric heating plate 9 is used to conduct heat. The oil is continuously heated to maintain a high temperature. Under the hig...

The invention discloses a tensile testing machine for metal material inspection, the tensile testing machine comprises a box body, a hydraulic cylinder and a base are fixedly mounted at the central positions of the upper wall surface and the lower wall surface in the box body respectively, and hydraulic fixing clamps are fixedly mounted at the telescopic end of the hydraulic cylinder and the upper wall surface of the base respectively; the working ends of the pair of hydraulic fixing clamps are oppositely arranged and located on the same vertical center line, an annular groove is formed in the lower portion of the inner wall of the box body, an annular sliding way is fixedly installed on the lower wall face of the annular groove, two pairs of sliding blocks are movably installed on the annular sliding way, and circular rings are fixedly installed on the upper wall faces of the two pairs of sliding blocks. The metal material resistance test device relates to the technical field of metal material resistance tests, two tests of the same tensile force at different temperatures or different tensile forces at the same temperature can be carried out, coking can be generated, a tensile test can be carried out on a coked metal rod, and convenience is brought to use of people.
Description
technical field [0001] The invention relates to the technical field of metal material resistance testing, in particular to a tensile testing machine for metal material testing. Background technique [0002] Metal is a substance with luster, ductility, easy electrical conductivity, thermal conductivity and other properties. Most of the metal elements on the earth exist in nature in a compound state. Very few metals such as gold, silver, etc. exist in free state. The invention patent with publication number CN103076229A discloses a liquid medium container of a tensile testing machine, including a container cover, an upper container and a lower container. The bottom of the lower container is provided with a liquid medium container. The valve is switched on and off, the lower container is fixedly connected with the pull-down force rod of the tensile testing machine, the pull-down force rod is connected with the lower clamp and placed in the lower container, the upper pull-up rod...
