Electro hydraulic servo steel strand testing machineIt is a four column, double screw, and oil cylinder bottom mounted main engine structure, with a semi open jaw seat and a piano type oil source control cabinet as the control oil source. The stretching space is located above the main engine, and the compression, bending, and shear tests are located below the main engine, between the moving crossbeam and the worktable.

The adjustment of the experimental space is achieved by moving the position of the middle crossbeam, which is driven by a gear reduction motor and a chain drive. The computer automatically controls the servo valve to complete the loading process of the sample, with multiple automatic control modes such as constant rate test force, constant rate deformation, and constant rate displacement. Smooth switching can be achieved between various control modes. The external controller and strong electric control system provide strong guarantees for the stable operation of the equipment.

Performance Characteristics

1. The host adopts a four column high rigidity frame structure, which provides stable support, smooth loading, and beautiful appearance;

2. The host base is precision cast to reduce equipment operating noise and improve equipment rigidity;

3. The moving crossbeam and upper crossbeam are both precision cast and processed to ensure the alignment of the sample clamping;

4. The mobile crossbeam lifting system adopts ground screw and precision gear reducer to reduce the noise generated during crossbeam lifting;

5. The semi open jaw seat prevents damage caused by the horn shaped deformation of the jaw seat, thereby improving the service life of the equipment;

6. The jaw adopts a dovetail groove structure, which has the advantages of easy installation, strong durability;

7. The measurement and control system has fast running speed, gentle interface, and multiple sample information input modes, which can meet the testing needs of different materials;

8. The sample information input is convenient, and multiple sample tests can be completed with the same sample information input at once;

　　Electro hydraulic servo steel strand testing machineIt has software self checking function, can self diagnose faults, and can measure the mechanical properties of steel strands such as tensile strength, specified non proportional elongation strength, elastic modulus, elongation rate, etc. It is an ideal testing equipment for industrial and mining enterprises, scientific research units, colleges and universities, engineering quality supervision stations and other departments.
