Embodiment 1-48

[0055] A bimetal thermal performance detection device, comprising a flexometer 1, a temperature-controlled oil tank 2 placed under the flexometer, and an electronic contact indicator 3 connected to the flexometer. The flexometer includes: a support platform 4, a sample clamping rod (frame) 5 arranged on the support platform and submerged in the temperature-controlled oil tank 2, and a measuring pen 6 that can move on the support platform. It includes a micrometer head 7, a measuring rod 8 connected to the micrometer head 7 via a connecting block 12, submerged in the temperature-controlled oil tank 2, and in contact with the sample.

[0056] The measuring pen can move on the support platform through the moving slideway at the top of the support platform, and a handle 16 is designed on the plane plate at the top of the support platform, which is fixed on the moving slideway, so that the above-mentioned flexometer can be easily moved.

[0057] The measuring rod has the same cross...

Abstract

The invention discloses a device and a method for detecting bimetallic thermo-sensitive property. The device comprises a torsion measuring device, a temperature control oil tank arranged below the torsion measuring device and an electronic contact indicator connected with the torsion measuring device, wherein the torsion measuring device comprises a bracket platform, a sample holding rod (bracket) arranged on the bracket platform and submerged in the temperature control oil tank and a measuring pen capable of moving on the bracket platform; and the measuring pen comprises a micrometer head and a measuring rod which is connected with the micrometer head by a connecting block and submerged in the temperature control oil tank and contacts a sample. According to the device and the method for detecting the bimetallic thermo-sensitive property, the 'specific thermal deflection value' of a thermal bimetallic sample at the temperature of between 20 and 300 DEG C can be measured, and the maximal measurement deviation does not exceed + / - 1.0 percent, which meets precision requirements of national standard GB / T8364-1987 'Test Method for Specific Thermal Deflection of thermostat Metals'.

Description

[0001] The invention relates to a detection device and a detection method for the physical properties of metal materials, in particular, the invention relates to a detection device and a detection method for measuring the thermal performance ratio bending of a bimetallic material. Background technique [0002] Thermal bimetal is a composite material formed by the component layers (two layers, or more than two layers) of metals (or alloys) with different expansion coefficients, which are firmly combined with each other along the entire contact surface. [0003] Due to the different thermal expansion coefficients of each component layer and the uneven distribution of internal stress in the thermal bimetal section, when the temperature of the thermal bimetal changes (such as: heating), the curvature of the composite material will change and produce deformation. When the deformation is limited, energy exchange is carried out, heat energy is converted into mechanical energy, and dis...
