Description
Technical Field
[0001] The utility model relates to a device for measuring the side expansion value of an impact test, and belongs to the technical field of metallurgical material testing and detection equipment. Background Art
[0002] When steel is subjected to impact test, the material's ability to resist fracture under triaxial stress conditions in the root area of the notch of the Charpy impact specimen needs to be measured. The deformation in this area is usually measured. The expansion value opposite the notch on the fracture plane is measured instead of the compression deformation, that is, the expansion value of the impact side is measured. The method of measuring the side expansion value needs to take into account that when the specimen is divided into two, it is rare to retain the maximum expansion value on both sides of the fracture plane. Half of the broken sample may contain the maximum expansion value on both sides or only include one side or neither side. It is necessary to measure the expansion value of each side of each broken sample and the defined undeformed area on one side of the specimen. The sum of the maximum expansion values on both sides obtained by the two half broken samples is the expansion value on the impact side. The traditional method is to measure the sample on a fixed dial indicator. Because the deformation of the sample on one side is small, when using the dial indicator to measure, it is easy to cause result deviation due to sample movement or inaccurate position. At the same time, the dial reading is used, which is not easy to find when zeroing, and there is a human error in the final result reading. In order to reduce the deviation and improve the accuracy of the measurement results, it is necessary to design a device for measuring the side expansion value of the impact test.
