Main application

WEW-D series of screen-display hydraulic universal testing machine is mainly used for tensile, compression, bending, shear and other mechanical properties of metal materials. After adding simple test equipment, it can also be used to test transmission chain, mining three-ring chain, high-strength bolts and cement, concrete, rubber and its products.

This machine is four columns, double screws, oil cylinder lower host structure, control oil source for the piano type oil source control cabinet. The tensile space is located above the main machine, and the compression, bending and shear tests are located below the main machine, i.e. between the moving crossbeam and the working table. Adjustment of the test space is realized by moving the position of the middle crossbeam, which is driven by a chain transmission driven by a gear motor. Manually adjust the size of the oil feed valve oil volume to meet the material tensile, compression, bending and other test speed adjustment. After the completion of the test, the computer can automatically calculate the modulus of elasticity of the material, tensile strength, upper and lower yield strength, non-proportional elongation strength, the maximum force total elongation, post-breakage elongation and section shrinkage and other test results, and can be output directly to the standard test report and test curves, but also can be output in EXCELL and WORD format statistical reports.

Performance characteristics

1, the host adopts four columns of high rigidity frame structure, stable support, loading smooth, beautiful appearance;

2, The base of the host adopts QT500-7 precision casting, which reduces the running noise and improves the rigidity of the equipment;

3, Moving beam and upper beam are precision casting, CNC precision machining, to ensure the alignment of the specimen clamping;

4, mobile beam lifting system using grinding screw, precision gear reducer, reduce the noise generated when the beam lifting;

5, Special structural design of the jaw seat, to prevent damage due to the jaw seat is flared deformation, improve the service life of the equipment;

6, the jaw adopts dovetail groove structure, hardness up to 58-62HRC, has the advantages of convenient installation, strong and durable;

7, measurement and control system running fast, gentle interface, with a variety of specimen information input mode, can meet the test of different materials; 8, specimen information entry is convenient, the same conditions of the specimen information can be entered once to complete the test of multiple specimens;

9, the same conditions of the specimen, can be various types of test curve superposition display, can clearly identify the stability of the material;

10, the test force display high precision, test force display the whole resolution of the same, to ensure the accuracy of the experimental data measurement;

11, test data (test force, loading rate) and test curve with the test process dynamic real-time screen display;

12, when the load exceeds 3-5% of the full scale automatic overload protection shutdown.
