Abstract
Description
Technical Field
[0001] The utility model relates to a thin plate clamping device for thermal simulation tests, belonging to the technical field of analysis and testing. Background Art
[0002] As a commonly used thermal simulation experimental device, the Gleeble device is often used to conduct various heat treatment process research tests on steel materials. Usually, the detection process of rod-shaped and thick plate metal specimens is relatively convenient, while there are many difficulties in the experimental operation of thin plate specimens. When rolling thin-gauge strip steel, due to the thin strip steel, especially during laboratory rolling, it is difficult to ensure the thickness tolerance, and a large clamping force is required for clamping, resulting in easy loosening during clamping. This is mainly because when performing static thermal simulation of thin plates on the Gleeble, it is necessary to evacuate the sample chamber to form a near-vacuum environment inside the sample chamber; as the temperature gradually rises or falls during the heat treatment process, due to the thermal expansion and contraction of the specimen to be tested, the specimen is prone to move, and the two chucks clamping the thin plate will squeeze or stretch inward. If the thickness of the thin-gauge specimen fluctuates greatly, it is easy to cause the specimen to loosen, resulting in the failure of the experiment. In severe cases, it will damage the experimental equipment. Summary of the Invention
[0003] Based on the above background, the utility model aims to provide a thin plate clamping device for thermal simulation tests according to the existing equipment conditions to solve the deformation problem of thin plate specimens during the experiment and ensure the normal progress of the experiment. The specific technical solution is as follows:
[0004] A thin plate clamping device for thermal simulation tests, the device includes chucks and inserts; the chucks of the device are symmetrically arranged, and each chuck is provided with a chuck boss, which is correspondingly inlaid with the insert, and the chuck and the insert are matched. The insert can be provided with insert strip steel clamping grooves of 0.1 - 2.0 mm according to different thickness specifications.
[0005] Further, a strip steel clamping groove is opened in the middle of the insert to clamp the thin plate.
[0006] Further, the position of the insert can be moved up and down according to the actual plate thickness to avoid the situation of loose strip steel caused by insufficient clamping.
[0007] Furthermore, the chuck and the insert are in close contact, offsetting the slip of the specimen due to thermal expansion and contraction during the experiment, and also avoiding the bending phenomenon of the specimen to be tested, improving the success probability of the experiment.
[0008] The beneficial effects of the present utility model are as follows: When this device conducts the Gleeble thin plate static thermal simulation experiment, by adjusting the position of the insert block, the loosening problem of thin-gauge strip steel during the test can be effectively avoided. At the same time, since there is a certain angle between the insert block and the chuck, according to the thickness of the thin plate specimen, by adjusting the position of the insert block, it is ensured that the insert block is in clamping contact with the thin-gauge strip steel, offsetting the slip of the specimen caused by thermal expansion and contraction during the experiment, and also avoiding the bending phenomenon of the specimen to be tested, thereby improving the success probability of the experiment.

[0013] The following further describes the present invention in combination with embodiments, but the embodiments should not be construed as limiting the present invention.
[0014] The present utility model provides a thin plate clamping device for thermal simulation tests, including a chuck 1 and an insert block 2; the chucks 1 of the device are symmetrically arranged, and there is a chuck boss 3 on the inner side of each of the chucks 1. The corresponding position of the insert block 2 has a groove, and the boss of the chuck 1 is embedded in the groove of the insert block 2. At the same time, the contact surfaces of the chuck 1 and the insert block 2 have a certain inclination, and this angle is 3 - 6°. At the same time, the inner side of the insert block is a strip steel clamping groove, and the size of the clamping groove is variable. Different insert blocks are set according to different strip steel thicknesses to facilitate the clamping of strip steels with different thicknesses.
[0015] During installation, select the insert block with a different strip steel clamping groove according to the thickness of the strip steel and install it in the chuck. At the same time, due to the fluctuation of the thickness of the thin-gauge strip steel and the difficulty of clamping, by adjusting the relative position of the insert block and the chuck, it is ensured that the strip steel is clamped tightly.
[0016] This device can prevent the thin plate specimen from bending during the Gleeble thin plate static thermal simulation experiment, resulting in the failure of the experiment.
[0017] The above is the technical solution of the present invention. Those of ordinary skill in the art can understand that it should be pointed out that for those of ordinary skill in the technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
