technical field

The utility model relates to the technical field of material hardness testing, in particular to a material hardness testing device.

Background technique

Material hardness test, as the name suggests, is to test the hardness of the material itself to avoid the problem of insufficient hardness of the product in the later stage, which affects the normal use of the material. The commonly used hardness testing device is called Rockwell hardness tester, which is the first in the world. The Rockwell hardness tester is designed according to the principle of Rockwell hardness test, which can test the hardness of metal only by touching the sample on one side. The accuracy conforms to the standard GB/T230, ISO6508, and is not lower than the desktop Rockwell hardness tester. The Rockwell hardness test method was originally proposed by American Rockwell (S.P.RocKwell and H.M.RocKwell) in 1914, and later they in 1919 and In 1921, the design of the hardness tester was improved twice, which laid the prototype of the modern Rockwell hardness tester. By 1930, Wilson (C.H Wilson) carried out an updated design, which made the Rockwell hardness testing method and equipment more perfect. Rockwell hardness testers with touch screen control and numerical display, as well as curve display and automatic printing of test data have been produced. The Rockwell hardness testing method is characterized by simple operation, rapid measurement, and direct access from dial indicators or optical projection screens or display screens. The reading, along with the Brinell and Vickers hardness testing methods, is one of the three most commonly used hardness testing methods.
