PLC controlled saddle tube (saddle) Dynamic fatigue testing machine (ISO standard)

PLC control saddle tube (saddle) dynamic fatigue testing machine (ISO standard) WD-8722A

First, the test principle: simulate the bicycle in the actual riding process, under different road conditions, the handlebar component will be given by the hand in different directions of the force, especially when riding on the bumpy road, the force is relatively large and frequent, so the quality of the handlebar component is related to the safety and convenience of the whole car. The testing machine is designed according to ISO 4210 related fatigue test standards. The whole test system is automatically controlled by computer, and the force application system adopts force closed-loop control. When the test force applied on the handlebars reaches the set force, it automatically returns and reverses.

2, according to the standard: ISO 4210

Iii. Test method:

1) During the test, the saddle tube (saddle assembly) is fixed on the test machine in accordance with the standard method, and the height of the loading beam can be manually adjusted to adapt to the size of the saddle tube;

2) Fix the saddle tube on the special fixture, adjust the upper and lower, left and right positions of the loading cylinder, so that the loading fixture can be just assembled on the saddle tube (or the loading block on the saddle), and fix the various parts.

3) Set the test force value and number of test requirements on the touch screen.

4) Adjust the maximum allowable deformation of the saddle tube, and the machine will automatically stop testing after exceeding this deformation;

5) Start the test procedure to start the test, the test reaches the set number or the specimen is damaged, the machine will automatically stop the test and retain the test results.

Four, the main technical parameters:

1) Display mode: full color LCD touch screen

2) Control mode: PLC and touch screen control

3) Sensor capacity: 5000N

4) Load element resolution: 1/10,000

5) Test force: 300N-1300N can be set

6) Force control accuracy: 0-5% (dynamic)

7) Test frequency: 0-5Hz (adjustable)

8) Number of tests: 0-999,999 times can be set

9) Loading mode: pneumatic loading

10) Database function: automatically record each measurement result to facilitate analysis and provide evidence

11) Equipped with fixtures: horizontal fixtures, 73° fixtures and saddle fixtures

12) Shutdown mode: The test piece breaks the system or automatically stops beyond the displacement

13) The solenoid valve is equipped with a guard to prevent damage.

14) With pressure regulating tank, better stable working pressure, so that the loading force is more stable.

15) Pneumatic components brand: Japan SMC or Germany FESTO

16) Power supply: 220V 5A

17) Air source: pressure 0.7MPa gas flow 300L/MIN

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

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

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