Servo controlled pull-back testing machine

Servo control office chair pull-back testing machine WSD-8603B

one. Test scope:

This machine according to BIFMA5.1EN1335-3 and other standards to test the back of the office chair after a certain amount of force and a certain number of tension, check the chair back and the chassis of the rotary chair fatigue resistance and damage to the components.

two. Applicable standard: BIFMA 5.1:2002 EN1335-3:2000 QB/T2280-2007

Three. Main composition

1. The size of the test force is measured and controlled directly by the force sensor, and the accuracy meets the standard requirements.

2. The loading function is realized through the servo motor, and the loading force value of the force sensor is self-dynamic test part

Four. Technical parameters:

1. Loading load: 0-- 200kg adjustable

2. Force loading accuracy: dynamic 5% static 1%

3. Travel: Controllable

4. Force sensor type: Spoke type (high accuracy, good stability, good strength)

5. Loading Angle: 90° with the back of the chair (adjustable pulley mechanism can adjust the Angle)

6. Test speed: 10~30 times/min can be set arbitrarily

7. Test times: 0-9,999,999 times can be set arbitrarily

8. Control mode: PLC control + force sensor to form force closed-loop control

9. Display mode: full color LCD touch screen

10. Data storage: computer memory and U disk

11. Report generation method: The data can be automatically printed on the ordinary computer through the U disk and the test report

12. Stop mode: Automatically stop when the set number of tests is reached, the specimen is damaged or the deformation is too large

13. Servo motor brand: Japanese imported brand (Mitsubishi or Panasonic)

14. Back loading module: in line with standard requirements and eccentric loading

15. Configuration seat load: 102kg 1 set above

16. Seat load set safety measures to prevent personal injury accidents caused by self-fall during the test.

17. Other appliances: Omron and Taiwan Shilin

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

19. The base of the machine is made of high-strength aluminum alloy profiles and equipped with adjustable water flat feet.

20. The profile is equipped with electroplated steel plate, which has high anti-rust ability and beautiful appearance.

21. Gas pressure: 6 KG/CM2

22. Power supply: 220V 50HZ 800w
