Abstract

The invention provides a Gleeble sample loading tool, belongs to the field of clamping tools and aims at providing a Gleeble sample loading tool capable of facilitating graphite flakes, tantalum sheets and test samples. The Gleeble sample loading tool comprises two grips, wherein semi-round straight slot openings on two grip connecting parts oppositely define a test sample mounting hole; first step slot openings oppositely define a tantalum sheet mounting hole; second step slot openings oppositely define graphite flake mounting holes; tantalum sheet mounting holes and graphite flake mounting holes are communicated with test sample mounting holes; the clamping part is circumferentially provided with a thermocouple groove which penetrates through the external surface of the clamping part through the test sample mounting hole along the radial direction of the test sample mounting hole. The Gleeble sample loading tool is capable of aligning the test sample, the tantalum sheets and graphite flakes, and effectively avoiding phenomena of cementation between the test sample and a pressure head and contact between the tantalum sheets and the pressure head, is beneficial to improvement on test, and furthermore, is capable of preventing external objects from colliding with a thermocouple and further causing thermocouple breakage.

Description

technical field

[0001] The invention belongs to the field of clamping tools, in particular to a Gleeble sample loading tool which is suitable for a sample whose radius is smaller than that of a graphite sheet and a tantalum sheet. Background technique

[0002] Gleeble, also called thermal simulation testing machine, is widely used in the simulation of material forming process. At present, when using a thermal simulation testing machine to simulate the material forming process, it is first necessary to load the sample, that is, put the graphite sheet, the tantalum sheet, the sample, the tantalum sheet and the graphite sheet in sequence between the lower indenter and the upper indenter, And try to make the centers of the sample, graphite sheet and tantalum sheet on the same straight line, the current sample loading operation is done manually. However, manual loading without aids has two major disadvantages:

[0003] 1. It is difficult to use, the thermocouple is easy to brea...
