Description

Technical Field

[0001] The utility model mainly relates to the technical field of plate hardness detection equipment, in particular to a plate hardness detection device. Background Art

[0002] Plates are flat rectangular building material boards made into standard sizes and are used in the construction industry to make components of walls, ceilings or floors. They also refer to metal plates made by forging, rolling or casting, which are divided into thin plates, medium plates, thick plates, extra-thick plates, and are usually made into flat rectangular building material boards of standard sizes.

[0003] Plate hardness testing is one of the ways to test plate quality parameters. Hardness is a professional term in physics. The ability of a material to locally resist a hard object pressing into its surface is called hardness. The local resistance of a solid to the invasion of external objects is an indicator for comparing the softness and hardness of various materials. It is mainly measured by the indentation method (Brinell, Rockwell, Vickers). The hardness value indicates the ability of the material surface to resist the plastic deformation caused by the pressure of another object, so as to verify whether the tested plate can meet the desired requirements.

[0004] At present, in the process of plate testing, the plate is mostly impacted by a detection head to test the hardness of the plate. Only one point on the plate can be tested each time. There are multiple points on the same plate, so each plate needs to be tested multiple times. However, in actual use, a plate may be impacted in different areas at the same time point, and not necessarily only one place is affected by external forces each time. Therefore, it is impossible to detect the stress changes and the limit value of the plate after multiple positions of the plate are impacted at the same time. Utility Model Content
