In-situ testing device for mechanical properties of variable-temperature tension-torsion composite load material

Abstract

The invention discloses an in-situ testing device for mechanical properties of a variable-temperature tension-torsion composite load material. The device comprises a base, two first grooves are symmetrically formed in an upper end of the base; a cross rod is fixedly connected to inner walls of the two first grooves, a first sliding block is slidably connected to a side wall of the cross rod, a fixing plate is fixedly connected to an upper end of the first sliding block, a second groove is formed in an upper end of the fixing plate, and a first clamping device for clamping the material is installed on an inner wall of the second groove. Materials with different thicknesses can be clamped through the movement of arc-shaped clamping plates; the material can be subjected to stretching detection under the action of a hydraulic oil cylinder; the middle of the material can be clamped through the relative rotation of two clamping hands, the material is driven to be bent upwards under the action of the upward movement of a transverse plate, the bending performance of the material is detected, a heating plate is driven to move back and forth through rotation of a third reciprocating lead screw, the material is evenly heated, and performance detection can be conducted on the material under the high-temperature condition.

Description

technical field [0001] The invention relates to the technical field of material performance testing, in particular to an in-situ testing device for mechanical properties of materials under variable temperature, tensile and torsion composite loads. Background technique [0002] Materials are those substances that humans use to manufacture articles, devices, components, machines or other products. With the development of science and technology, more materials are used in important places such as military equipment, which makes the mechanical properties of materials during use requirements are gradually increasing. [0003] Due to the harsh conditions of military equipment and other facilities in use, materials will be used at different temperatures, but at present, the performance testing of materials is carried out at room temperature, and the current testing of mechanical properties of materials is single Therefore, in the process of material production and production, the ...
