Description

Technical Field

[0001] The utility model belongs to the technical field of metal product detection, and in particular relates to a quality detection instrument for metal products. Background Art

[0002] The hardness quality testing instruments for metal products are usually tested using a hardness tester or Rockwell hardness tester. These instruments can be used to measure the hardness of metal products to ensure that they meet specific standards or specifications. Hardness testing is one of the important methods for evaluating the strength and wear resistance of metal materials, so it is widely used in manufacturing and quality control processes. Common hardness testing methods include Rockwell hardness test, Brinell hardness test, Vickers hardness test, etc.

[0003] The hardness quality testing instrument of metal products can be used for quality control in the manufacturing process. By testing the hardness of metal products, it can be ensured that their hardness values ​​meet specific standards or specifications, thereby ensuring the quality of the product. Hardness is one of the important indicators for evaluating the strength and wear resistance of metal materials. By using hardness testing instruments, the hardness value of metal products can be accurately measured to evaluate their quality and performance. Hardness testing instruments can help engineers and designers choose suitable metal materials. By testing the hardness of different materials, their hardness characteristics can be understood, so as to select the most suitable material for a specific application. During the processing and treatment of metal products, hardness testing instruments can be used to detect the treatment effect. For example, for heat-treated metal products, hardness testing can be used to evaluate the treatment effect and the strength change of the material. Metal product manufacturers can use hardness testing instruments to provide after-sales service and quality assurance. By conducting hardness tests on manufactured metal products, product quality can be ensured and satisfactory after-sales service can be provided to customers. The problem with the above technology is that when using a hardness tester to test the hardness of metal products, the metal products need to be docked with the detection end of the hardness tester through a lifting platform for detection. However, there are no components between the lifting platform and the detection end of the hardness tester to protect the metal products, which causes the metal products to splash around when damaged, thus posing certain safety hazards and reducing the safety of using the hardness tester.
