Description

Technical Field

[0001] The utility model relates to the technical field of centering tooling for notched impact specimens, in particular to a notch centering device for notched impact specimens. Background Art

[0002] With the increasing application of metal materials in various industries, the detection of their physical properties is particularly important. In the detection of the physical properties of metal materials, impact testing, as a common inspection item, is of great significance for evaluating the material's ability to resist impact deformation. Especially in the physical property inspection of medium and thick plate materials, hot-rolled plates, seamless steel pipes and other products, impact testing is an indispensable part. However, the sample preparation process of impact specimens is relatively complicated and involves multiple processes, among which the quality of notch alignment is even more difficult to control. In the notch impact test, the notch alignment of the specimen directly affects the accuracy of the test results. If the notch alignment is inaccurate, it will not only increase the test error, but may also mislead the impact deformation behavior of the specimen, thereby affecting the accurate evaluation of the material's impact properties;

[0003] At present, in the finished product inspection room of the Quality Inspection and Metrology Center of Ansteel Co., Ltd., the preparation of the impact specimen notch has become a difficult problem in processing. Traditional notch alignment methods mostly rely on manual operation, which not only increases the difficulty of work, but also makes it difficult to ensure the accuracy and stability of alignment. Therefore, we proposed a notch alignment device for notched impact specimens to solve the above problems. Utility Model Content
