GWE Special testing machine for micro electro hydraulic servo steel strand
Main purpose:

This product is mainly used for tensile test of steel strand and tensile test, compression test, bending test and shear test of metal material.

Patents:
ZL 202120676924.9 Electro hydraulic servo steel strand testing machine

Product features:

1. Adopt six column and double space frame structure, which has the characteristics of high rigidity and good stability.

2. Hydraulic automatic clamping fixture is adopted, which is reliable and convenient.

3. The center beam is equipped with a gap adjusting disc device, which can effectively eliminate the transmission gap between the rod and the nut, and make the section more flat when the pattern is pulled off.

4. The special jaw structure can increase the maximum clamping area of the steel strand, plus the customized high-purity aluminum carborundum sheet and the jaw clamping mode designed separately for the steel strand testing machine, which can minimize the slip of the steel strand during the test and make the test results more accurate.

5. Cooperate with high toughness protective net to form isolation between the test space and the operator, which can effectively ensure the safety of the operator.

6. The force measuring element is a high-precision spoke sensor, which has the characteristics of high precision and long-term stability, ensuring the force measuring accuracy of the whole testing machine.

7. Adopting the latest servo pump control technology, the system has low noise, strong anti pollution ability and long-term trouble free operation.

8. PID control strategy is used to realize load, displacement and deformation three closed-loop control, and can smoothly switch between the three controls.

9. It has different levels of authority management functions to meet the multi role management requirements of the laboratory.

10. Support the personalized setting of test report, and the test data can be directly exported to excel document.

11. It has disk storage of test results, printing of test results and test curves, report processing of batch test results, database management and other functions, with network interface reserved.

12. The controller of the testing machine supports the remote program upgrade function and can meet the diversified needs of customers in a timely manner.

13. The test software has data upload interface with domestic mainstream Internet companies.

14. The force measuring cabinet has a novel embedded design, which can bear a voltage range of 85-250v and has stronger anti-interference performance.

15. It adopts touch screen and keyboard dual control mode, with neat and beautiful appearance, meeting the preferences of different technicians.

16. 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.

17. Microcomputer automatic data acquisition and processing as well as synchronous screen display of test data and test curve are adopted.

18. The test curve can be locally enlarged and multi curve superposition comparison can be carried out.

19. The test software supports the simultaneous control of compression and bending resistance of the testing machine, which can greatly provide the use efficiency of the equipment.

20. The test software has an open test standard library mode, and operators can add standards as required to meet the test requirements.

21. It has many auxiliary functions such as operation guide, error alarm and online help.
