Main purpose:
It is mainly used for tensile, bending, compression, shearing, peeling, tearing and other tests of various metal and non-metal materials. For example, the drawing of screw steel, the drawing and bending of high-strength bolt and high-hardness metal material, the residual deformation of steel plate mechanical connector, the compression of metal and concrete, etc.

Product features:
1. The oil cylinder is set down, the four column frame structure and the six column frame structure are adopted, with good rigidity and stable structure.
2. Use the hydraulic chuck to clamp the sample automatically.
3. Adopt high-precision load sensor to measure force, with high precision and wide range.
4. Adopt high precision displacement sensor.
5. Adopt high-performance servo valve control.
6. Use high-precision extensometer to measure sample deformation.
7. The double nut reverse clearance structure is adopted to solve the problem that the gap of the parts increases due to the long-term running wear of the nut, so as to ensure the loading rate, which is far higher than the standard of gb228.
8. Adopt networked measurement and control system, with gain adjustment, zero point fullness and other functions, to ensure the smooth operation and accurate measurement of the machine.
9. It can realize constant rate force control, constant rate stress control, constant rate strain control, constant rate stroke control, low cycle fatigue control and user self programming control.
10. It can draw a variety of test curves, such as force deformation, force displacement, stress-strain, force time, etc.
11. The main components of the hydraulic system are imported parts, such as the imported Siemens motor and the imported radial piston oil pump, which make the recording accuracy of the testing machine higher, the noise lower, the durability better, and enhance the stability of the machine.
12. Computer and electro-hydraulic servo system are used for control loading and full automatic control. It can complete the test independently according to the preset stress rate and curve form, and display the dynamic display of load, rate, time and test curve. All tests can be completed only by setting parameters once.
13. The force measuring cabinet is equipped with the current advanced industrial grade embedded tablet computer, which can withstand the voltage range of 85-250v and has stronger anti-interference performance. The computer adopts touch screen technology, which can be used for touch operation or keyboard operation. It is more ergonomic and convenient to operate.
14. By using Windows system control software, the elastic modulus E, upper yield strength Reh, lower yield strength rel, specified non proportional extension strength RR, tensile strength RM, specified total extension strength RT, yield point elongation and other technical parameters can be automatically obtained.
15. Microcomputer automatic data acquisition and processing and synchronous screen display of test data and test curve are adopted. The test curve can be locally enlarged and the superposition comparison of multiple curves can be carried out. It has the functions of disk storage of test results, printing test results and test curves, report processing of batch test results, database management, etc., and has network interface. It has the functions of LAN networking and remote data seamless connection.
