Chair foot compression testing machine

Computer servo control office chair foot compression testing machine WSD-8608

one. Through the testing machine to apply a specified load to the chair foot in a certain sequence (or apply a specified load) and continue for a specified time, through the test, there is no sudden and obvious change in the structural integrity of the chair foot base, in order to assess the ability of the chair foot to withstand compressive stress.

two. Design basis: BIFMA5.1:2002 QB/T2280-2007 GB/T16491-96 GB/T2611-92 GB/T13634-92 ISO7500-1:86

Characteristics of the testing machine: Compared with similar testing machines on the market at present, the advantages are as follows:

1. For the unique widening design of office chair, a variety of static tests can be conveniently implemented on this machine.

2. Unique computer software design and advanced control technology can easily achieve a variety of force loading and holding tests.

3. More simple operation, fully realize computer automatic control of the machine, automatic rise, automatic fall. When testing, just press the "test" key, the test can be automatically completed by the computer, without manual intervention.

4. The testing machine automatically draws various pressure, displacement and time curves after data collection, makes test reports and can automatically print test reports.

5. The testing machine has automatic homing function, which will automatically return to the initial test position after each test, so as to facilitate the next test.

6. Test method: automatic return after the test is completed

7. Displacement accuracy: ≤1%

8. Position sensor: high-precision encoder picture for reference only, subject to the actual

9. Control mode: computer automatic control

10. Servo control mode: force, displacement, speed three closed-loop control

11. Drive screw: high precision T-screw

12. Motor: servo motor

13. Other electrical appliances: Omron and Taiwan Shilin

14. Test report: Automatically generate test report according to customer requirements

15. Maximum capacity protection: The machine is equipped with an automatic protection computer system to prevent the load from exceeding the safe capacity of the machine. Different safety capacities can be set, and when the set capacity is reached, it can automatically stop to protect the force sensor and the testing machine itself.

16. Breakpoint stop: When the test is broken or damaged, the test will automatically stop, no need to press stop.

17. Dust jacket: the transmission screw is equipped with a dust proof device to prevent dust and test objects from entering the transmission screw, and has the function of increasing the life and accuracy of the instrument, beautiful instrument and so on

18. Equipped with moving beam upper limit and lower limit position induction device: when the moving beam reaches the highest point and the lowest point, the micro switch automatically turns off the power, protects the force sensor and the motor, and can avoid damage to the instrument due to improper use by the operator.

19. The main body of the machine is steel component, high strength, not easy to deformation.

20. The base of the machine is solid steel with good stability, equipped with reinforcing bars and flat feet for water transfer.

21. Electrostatic spraying of machine appearance, electroplating of other parts, high rust prevention ability, beautiful appearance.

22. Power supply: 220V 50HZ 15A
