Description

Technical Field

[0001] The utility model relates to the technical field of metal detection, and more specifically, to a local strength detector for metal products. Background Art

[0002] The strength of metal products usually refers to the ability of materials to withstand external forces without being damaged. It is usually measured through mechanical property tests such as tension, compression, and bending. Different metal materials have different strength characteristics. Some high-strength metals such as titanium alloys and high-strength steels are widely used in engineering and manufacturing.

[0003] The strength test of metal products mainly includes tensile test, hardness test, impact test and non-destructive test. Among them, hardness test is a commonly used method to test the strength of metal products, such as Brinell hardness, Rockwell hardness, etc., which can reflect the ability of metal materials to resist local deformation. It mainly evaluates the hardness value by measuring the ability of the metal material surface to resist indentation deformation or scratches. Rockwell hardness is an indicator to determine the hardness value based on the depth of plastic deformation of the indentation, with 0.002 mm as a hardness unit. Using different indenters and different test forces in the Rockwell hardness test will produce different combinations, corresponding to different Rockwell hardness scales.

[0004] The existing Rockwell hardness tester lacks a fixing device when in use, and the metal product may be offset during testing. At the same time, when testing a part of the metal product, the position of the metal product is adjusted by the operator's feeling and proficiency, making it difficult to fully and accurately test all positions of the metal product.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a local strength detector for metal products. Utility Model Content
