Description
Technical Field
[0001] The utility model relates to the technical field of bending strength detection of metal materials, and particularly relates to a bending strength detection device for metal materials. Background Technique
[0002] The bending strength of a metal material refers to the maximum stress or maximum bending force that the material can withstand when subjected to bending loading. Bending strength is one of the important indicators for evaluating the bending resistance of a material under bending load. Usually, the bending strength of a metal material can be determined by conducting a bending test. In the bending test, a standardized specimen is clamped on a bending testing machine, and a downward load is applied to cause the specimen to bend and deform. By measuring the deformation and loading conditions of the specimen, the bending strength of the material can be calculated. A metal material bending strength detection device is usually referred to as a bending testing machine or a bending test equipment, and these devices are used to evaluate the bending performance and bending strength of metal materials under stress.
[0003] There are three-point bending detection equipment and four-point bending detection equipment for metal material bending strength detection. When using different point positions to detect the bending strength of metal materials, it is necessary to replace the detection equipment, which is rather inconvenient. Secondly, the metal material to be detected is within the clamping device, and during the detection process, the metal material is likely to fall off. Finally, the height and the distance between the clamping devices cannot be adjusted. Therefore, a bending strength detection device for metal materials is proposed to solve the above problems.
