Description

[0001] The utility model relates to the technical field of hardware hardness detection, in particular to a hardware hardness detection device. Background Art

[0002] Hardware refers to tools made of gold, silver, copper, iron, tin and other metals through processing and casting, which are used to fix things, process things, and decorate. Hardness testing is required in the production process of precision hardware. Hardness testing is the fastest, most economical and simplest test method to evaluate the mechanical properties of metals. The main purpose of hardness testing is to determine the suitability of materials, or the effect of special hardening or softening treatment of materials for their use purposes. When hardware is tested for hardness, it is usually placed at the Rockwell hardness tester, with a special indenter, pressed into the surface of the tested metal under the action of two loads applied successively, so as to test the hardness of the hardware.

[0003] When the hardness tester of the prior art is used to test the hardness of hardware, some irregular hardware is placed on the workbench for hardness testing after being compressed. The hardware is prone to shake during the hardness testing under compression, thereby affecting the accuracy of the hardness measurement of the hardware. For this reason, we propose a hardware hardness testing device. Utility Model Content

[0009] Furthermore, the rough surface block is a disc-shaped block, and the outer disc surface of the rough surface block is set as a rough grain surface; the disc-shaped block of the rough surface block can contact the hardware with high friction through the grain surface.
