Function summary:

       The microcomputer-controlled tensile stress relaxation testing machine has the characteristics of compact structure, simple and easy to use, and can be used to test the mechanical properties of tensile stress relaxation of metal materials (such as steel strands, etc.) with a maximum load of 600kN at room temperature。

        The main machine is composed of frame, loading mechanism, reaction frame, etc., which is equipped with precision ball screw, reducer, left and right drawing anchor, etc。The transmission loading system uses a well-known servo driver to control the servo motor, drive the lead screw to move in a straight line, and apply load to the sample。The device has the advantages of compact structure, reasonable structure, high rigidity, high control precision, low noise and easy use。

Meet the criteria:
