Environment-controllable high-temperature mechanical testing machine

Abstract

The invention discloses an environment-controllable high-temperature mechanical testing machine and belongs to the technical field of structural material mechanical property test and detection equipment. The environment-controllable high-temperature mechanical testing machine mainly solves the problem that the existing mechanical testing machine cannot test and detect mechanical properties of an object with a temperature of 1500 DEG C or more. The environment-controllable high-temperature mechanical testing machine is characterized in that a heating furnace casing and a heat-insulation layer also comprise parts extending to two end surfaces but an inlet and an outlet, a heating member is a resistance heating element, heat shields are arranged outside two end surfaces of the heating furnace, a vacuum chamber with air exhaust, air inflation and vacuum chamber operation doors having static sealing structures is adopted, a base, a servo system, a stand column, an upper installation base, a clamping mechanism and a heating furnace are installed in the vacuum chamber, and an air inflation system is connected to an air inflation port of the chamber body. The environment-controllable high-temperature mechanical testing machine can realize sample air, vacuum and controllable atmosphere test environment and realize mechanical performance test and detection at a temperature of 1500-1600 DEG C and vacuum and protective atmosphere mechanical performance test and detection at a temperature of 1600 or more.

Description

technical field [0001] The invention belongs to the technical field of structural material mechanical property test and detection equipment. It specifically relates to a high-temperature mechanical testing machine capable of controlling the environment, in particular to a mechanical testing machine for testing and detecting the mechanical properties of structural materials at temperatures above 1500°C. Background technique [0002] The traditional mechanical testing machine tests the mechanical properties of structural materials under the above load modes by applying tensile, compressive, bending, and shearing forces to the sample, and is used for performance evaluation of structural materials. It is divided into two types: room temperature mechanical testing machine and high temperature mechanical testing machine. kind. The room temperature mechanical testing machine applies external forces such as stretching, compression, bending, shearing, etc. From the beginning of loa...

AI Technical Summary

Problems solved by technology

With the development of material science, newly developed high-temperature structural materials will be able to work for a long time at ambient temperatures of 1500°C and higher. Traditional high-temperature mechanical testing machines have been unable to accurately measure the high-temperature mechanical properties of such materials.
