What requirements does a steel strand tensile testing machine meet to be a good machine

At present, there are two types of steel strand tensile testing machines. Many manufacturers' steel strand testing machines cannot be called steel strand tensile testing machines from a professional perspective. Many manufacturers' steel strand testing machines directly increase the height of the column screw on the basis of the universal testing machine. For such a steel strand host, the severe shrinkage process in the most important parts is quite unfamiliar.

The important part of the steel strand testing machine is the special production of the clamp seat, which requires special design of the angle of the clamp seat. In addition, the national standard for steel strand stretching stipulates that the stretching space needs to be within one meter, which requires a clamping distance of about 25 centimeters for the style. This sufficient clamping distance can ensure that the stretching test process effectively prevents slipping. If the universal testing machine is simply raised, the clamping range will not meet the national standard requirements for steel strand testing machines, and the defect is severe slipping.

The steel strand special testing machine we produce has an elongated jaw seat and specially designed jaws that are clamped in a circular arc shape, effectively ensuring uniform force distribution on the steel strand sample and avoiding uneven force distribution caused by clamping angle issues, which can damage the steel strand pattern and lead to uneven force distribution. In this way, stretching the steel strand will cause the steel strand pattern to break directly from the jaws, and the test data measured will definitely be inaccurate. Our Jinan Liling Testing Machine Company produces steel strands with specially designated jaw seat design and testing space selection on the upper edge of the testing machine host. The ultra-high coaxiality of the testing machine host also effectively ensures that the test breaks from the middle.

The high coaxiality, ultra-high rigidity of the host, and unique design of the jaws, as well as layer by layer process control, ensure that the pattern breaks from the middle during stretching and effectively avoid the slip of the pattern during the stretching process, which may cause inaccurate test data. Therefore, if you have any concerns about choosing a steel strand special testing machine, Jinan Liling Testing Machine Co., Ltd. is your best choice.
