Problems solved by technology
[0002] The Brinell hardness tester is mainly used for the hardness measurement of cast iron, steel, non-ferrous metals and soft alloys. The Brinell hardness test is a test method with the largest indentation in all hardness tests. It can reflect the comprehensive performance of the material. Affected by the microsegregation of the sample structure and the uneven composition, it is a high-precision hardness test method. In the prior art, the Brinell hardness tester uses a lever and a weight to apply a load. When measuring, the material Placed on the workbench, the indenter applies the load. The material placed on the workbench is easy to shake, and the test is not very convenient. In addition, the counterweight used for the test is not properly placed, and it is generally hung on the counterweight rod, which is very uncomfortable to use. convenient

Description
Technical field [0001] The invention relates to a metal material hardness testing device, in particular to a small load Brinell hardness tester. Background technique [0002] The Brinell hardness tester is mainly used to determine the hardness of cast iron, steel, non-ferrous metals and soft alloys. The Brinell hardness test is the test method with the largest indentation in all hardness tests. It can reflect the comprehensive performance of the material. Affected by the micro-segregation and uneven composition of the sample structure, it is a high-precision hardness test method. In the prior art, the Brinell hardness tester uses a lever and a weight to apply load. When measuring, the material Placed on the workbench, the material placed on the workbench under the load applied by the indenter is easy to shake, and the test is not very convenient. In addition, the test weight is not placed in a suitable place, and it is generally hung on the weight rod. Convenience. Summary of t...
