In the design process of the microcomputer-controlled relaxation testing machine, it has absorbed the design concepts and structural characteristics of famous relaxation testing machine companies in Germany and Italy, and is developed according to the relevant national standards of the steel strand relaxation test. It is specially used for steel strands, Relaxation test of galvanized steel wire and threaded steel bars. It is specially designed for manufacturers and users of steel strands. This series of testing machines are mainly used for the relaxation test of steel strands, which can detect the uniaxial tensile relaxation strength of steel strands and other metal wires. It can be widely used in quality inspection departments, construction units, steel strands and steel bars production enterprises. It is a new type of test equipment for modern building mechanics tests. Meet GB-T 5224-2003 "Steel wire for prestressed concrete", GB/T10120-2013 "Metal stress relaxation test method".
The machine adopts a fully digital servo speed control system with high speed regulation accuracy and stable performance and a servo motor as the drive system. The controller is the core of the control system. The control and data processing software with WINDOWS as the operation interface realizes the test force and the peak value of the test force. , The screen display of beam displacement, test deformation and test curve, all test operations can be automatically completed on the computer by the mouse.
