With the development of the national economy, the technical requirements of the tensile testing machine are getting higher and higher. The previous testing machine used a dial to display the force value. Today's tensile machine is operated by a computer, which is more convenient and accurate. The original tensile machine is mechanical. For example, as early as 1880, the United Kingdom had produced a lever hammer type material testing machine, and in 1908, it produced a universal testing machine loaded with nuts and screws. However, due to the complex structure, large volume and cumbersome operation, only static tests can be carried out, so it is eliminated. In the existing tensile testing machine, the screw is directly suspended on the bearings of the upper and lower brackets of the tensile testing machine, and it is easy to cause axial tension when doing the test. Serial movement, thus causing inaccurate test data. The clamping part of the chuck of the tensile testing machine is a plane. When the chuck clamps the paper, the chuck and the paper are in contact with the end face of the chuck. The contact area is large, and the pressure per unit area The strength is small, when the paper is clamped, sometimes it is easy to slip, and the result of the tensile test cannot be accurately recorded, and the data can only be read roughly, which greatly affects the test result. Therefore, people hope to invent and create a A new type of tensile testing machine to solve these problems.
