Embodiment 1

[0023] In Embodiment 1 of the present invention, the high-temperature mechanical performance test required for the design of the auto glass hot bending forming process; The upper part of the second clamping body 3 has a U-shaped second clamping portion 301 .

[0024] In the first embodiment of the present invention, the first positioning hole 202 is provided on the first clamping part 201, the second positioning hole 302 is provided on the second clamping part 301, and the first positioning hole 202 A first positioning pin 203 is provided, and a second positioning pin 303 is provided at the second positioning hole 302; preferably, in order to increase the force contact area, the first positioning pin 203 and the second positioning pin 303 can be changed to non-standard A part with a rectangular cross-section.

[0025] In Embodiment 1 of the present invention, the applicable flat glass sample 4 has a thickness of 2 mm to 3.5 mm, and a test temperature of 500°C to 750°C, which ...

Embodiment 2

[0028] In the second embodiment of the present invention, when designing the heating and softening process of automobile glass, the high-temperature mechanical performance test required; the lower part of the first clip body 2 is provided with a first wedge-shaped installation groove 204, and the second clip body 3 is provided with a second wedge-shaped mounting groove 304.

[0029] In Example 2 of the present invention, the applicable flat glass sample 4 has a thickness of 5 mm to 15 mm, and the test temperature is 300°C to 600°C. Since the tested flat glass sample 4 is relatively thick, in order to avoid stress concentration, it is necessary to increase the contact area , the test temperature is near the softening temperature of flat glass.

[0030] In the second embodiment of the present invention, a plate glass sample 4 with a thickness of 8mm is selected, and the test temperature is determined to be 500°C. The upper part of the plate glass sample 4 has a first wedge-shape...

Abstract

The invention relates to a testing device and a testing method of high-temperature mechanical properties of sheet glass. The testing device is characterized by comprising a frame, wherein a first clamp body and a second clamp body which are matched with each other are arranged at the upper part of the frame; a sheet glass sample is clamped between the first clamp body and the second clamp body. The invention also relates to a testing method of high-temperature mechanical properties of sheet glass. The testing device is simple and reliable in structure design, simple to operate, large in testing temperature range, rapid in testing speed and powerful in function; the testing device and the testing method can be used for testing high-temperature tension, high-temperature creep and relaxationof the sheet glass material and researching the viscoelasticity property of the sheet glass material.

Description

technical field [0001] The invention relates to a test device and a test method for high-temperature mechanical properties of flat glass. Background technique [0002] Glass is widely used in packaging, construction, home and vehicle manufacturing. With the rapid development of modern high-tech and the urgent requirement of pursuing high-quality life, the requirements for the physical and mechanical properties of glass products are getting higher and higher. Due to the inherent mechanical brittleness of glass, it is difficult to test the mechanical properties, especially the measurement of the mechanical properties at high temperature, so the data of high temperature mechanical properties are especially lacking. Glass is a high-temperature viscoelastic material with complex performance characterization, and countries around the world have not formulated corresponding viscoelasticity test standards. When the mechanical properties of flat glass are tested with the fixture of...
