Sofa fatigue durability testing machine WSD-8620


one. Test principle:


This test is suitable for the mechanical property test of the sofa, mainly testing the fatigue resistance of the seat surface, back and armrest of the sofa. During the test, the loading module of a certain shape and weight is repeatedly loaded on the surface of the seat, the back and the surface of the handrail in the loading form and frequency specified in the standard. Simulate the ability of each part of the sofa to bear long-term repetitive loads under daily use conditions, so as to improve the product structure or packaging reference.


two. Applicable standard: QB/T 1952.1-2003 Appendix A


Three. Main composition


1. Control mode: PLC and touch screen + load element to form closed-loop force control.


2. Can set the test force, and can directly display the test force in real time, and automatically alarm various faults.


3. Number of tests: 0-- 999,999 can be set arbitrarily, and can directly display the number of tests in real time, automatic stop after reaching the set number, stoppage or power off will automatically retain the test results.


4. Seat compression performance test: equipped with high-precision displacement meter can complete the seat compression performance test.


5. Safety device:


1). Maximum capacity setting value: When the sense of force reaches this value, it will automatically stop.


2). Maximum displacement setting value: When the displacement reaches this setting value, it will automatically stop.


3). Automatic detection of circuit switch, automatic shutdown of leakage.


4). Failure stop: When the specimen is damaged, it will automatically stop.


5). The up and down lifting has the upper limit and the lower limit micro-motion protection device: when the upper limit or lower limit is reached, the micro-switch turns off the power and automatically stops to prevent improper operation from causing damage to the instrument.


6. Control mode: set load, frequency setting, time setting.


7. Equipped with solenoid valve, pressure regulation filter oil filter water double, equipped with buffer tank, constant air pressure.


8. It can basically realize unattended test, the test will be automatically stopped when the test is completed or the specimen is damaged, and there is an audible and visual alarm, and the test results will be automatically retained.



Four. Technical parameters:


1. Load unit capacity: 100kg, 200kg each 2 50kg 1


2. System force accuracy: ±1% (static) 0-5% (dynamic)


3. Test frequency error: ±1 time


4. Surface loading module loading mass weight: 50±5Kg


5. Weight of metal plate: 70±0.5Kg


6. Armrest loading force: 250N


7. Backrest loading force: 300N


8. Test speed: 5-30 times /min


9. The width of the armrest can be tested: 580--850mm


10. Displacement meter measuring range: 600MM


11. Displacement accuracy: ± 0.5MM


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


13. Display mode: full color LCD touch screen


14. Data storage: computer memory and U disk


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


16. Brand of cylinder and other pneumatic components: festo


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


18. Maximum size of test specimen: 220x120x60CM (seat surface) (LxWxH)


19. Other electrical appliances: Omron and Taiwan Shilin


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


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


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


23. Power supply: single-phase 220V 50HZ 1kw


24. Air source: 0.6MPA


5. Equipment details:


2. 1 control cabinet


3. Pull 5 pressure sensors


4. The weights are matched according to the standard


5. Other accessories: several air pipes.


6. 1 copy of instructions


7. 1 certificate
