Background technique

Profiles are combed materials with a certain cross-sectional shape after plastic processing. They are widely used in the manufacture and installation of building structures and equipment. After the production of profiles is completed, in order to ensure the overall production quality of profiles, people often The mechanical properties of the profiles themselves are tested, so as to screen out the profiles that do not meet the requirements.

In the testing process of the existing profiles, most of the hardness tests are performed by the Webster hardness tester. However, in the actual measurement process, the Webster hardness tester needs to be kept perpendicular to the tested profile, but the Webster hardness tester has The overall volume is small, and the Webster hardness tester is prone to skew when the operator's palm is sweaty and the hand is slippery, which in turn causes the indenter in the Webster hardness tester to be broken or bent, causing unnecessary damage to the instrument. .
