Description

Technical Field

[0001] The invention relates to the technical field of material strength detection devices, and in particular to a honeycomb absorbing material strength detection device. Background Art

[0002] Absorbing materials refer to a type of material that can absorb or significantly reduce the electromagnetic wave energy received on its surface, thereby reducing electromagnetic wave interference. In engineering applications, in addition to requiring the absorbing material to have a high absorption rate of electromagnetic waves in a wider frequency band, it is also required to have properties such as light weight, temperature resistance, moisture resistance, corrosion resistance, and high strength. In order to improve the strength of the absorbing material, the absorbing material will be made into a honeycomb shape to increase the strength of the absorbing material.

[0003] When testing the strength of the absorbing material, a material strength testing device can be used to extrude the corrugated absorbing material to determine the strength of the absorbing material. In order to ensure the accuracy of the test, multiple pieces of material will be tested at one time when testing the material. When the existing testing device is testing, after testing a piece of material, the tested material is removed, and then another material is replaced for testing until all the material test pieces are tested.

Then, the pressure block can be driven by the detection device body to press down the test block material to detect the four materials. When the pressure block is pressed down, the second piston, the square block and the threaded rod support one side of the turntable, which can prevent the pressure of the pressure block from pressing the turntable crooked.
