This machine has a four column, double screw, and oil cylinder bottom mounted main structure, and the control oil source is a piano type oil source control cabinet. The stretching space is located above the host, and the compression, bending, and shear tests are located below the host, between the moving crossbeam and the workbench. 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. Manually adjusting the oil inlet volume of the oil delivery valve can meet the adjustment of the testing speed for materials such as tension, compression, and bending. After the experiment is completed, the computer can automatically calculate the elastic modulus, tensile strength, upper and lower yield strengths, specified non proportional elongation strength, maximum total elongation at break, elongation at break, and section shrinkage of the material, and can directly output standard test reports and test curvesOutput statistical reports in EXCELL and WORD formats.

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 adopts QT500-7 precision casting to reduce equipment operating noise and improve equipment rigidity;

3. The moving crossbeam and upper crossbeam are both precision cast and CNC precision machined 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 specially designed 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 with a hardness of up to 58-62HRC, which has the advantages of easy installation, sturdy and durable;

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;

9. Samples under the same conditions can be overlaid and displayed with various test curves, which can clearly identify the stability of the material;

10. The precision of the test force display is high, and the resolution of the test force display remains unchanged throughout the entire process to ensure the accuracy of experimental data measurement;

11. The experimental data (experimental force, loading rate) and experimental curve are dynamically displayed in real-time on the screen during the experimental process;

12. When the load exceeds 3-5% of the full range, the automatic overload protection will shut down.
