Description

Technical Field

[0001] The utility model belongs to the technical field of impact testing machines, and in particular relates to a temperature-controllable impact testing machine. Background Art

[0002] An impact tester is a device used to test the performance and durability of materials, products or structures when subjected to impact or shock loads. It can simulate various impact loads, such as high-speed impact, explosion shock, earthquake shock, etc., to evaluate the strength, stiffness, durability and destructive characteristics of the tested object. An impact tester usually consists of an impact device and a test sample support system. The impact device usually includes an impact head that can impact the test sample at high speed. The support system usually includes a fixture or bracket to fix and support the test sample and ensure that it remains stable during the impact process.

[0003] Common impact testers usually need to control the sample at a certain temperature when conducting tests. In traditional impact tests, the sample is usually heated to a certain temperature using a heating device, and then the sample is placed on a clamping device for clamping and fixing, and then the impact head is used to perform the impact test. However, in the process of taking the sample from the heating device to the clamping device, it is easy to cause the temperature of the sample to be replaced with the external temperature, thereby affecting the stability of the sample and the test results. Therefore, it is necessary to provide a controllable temperature impact tester to solve the problems raised in the above background technology. Utility Model Content
