PLC controlled frame horizontal force fatigue testing machine (ISO standard)

Touch screen control frame horizontal force fatigue testing machine (ISO standard) WDSD-8703B

First, the test principle: In the actual riding process of the simulated bicycle, the wheel will be affected by the external force forward and backward, which will be transmitted to the front tube through the front fork, and the first tube will constantly bear the external force. The quality of the first tube is related to the safety and convenience of the whole car. The testing machine is designed according to the ISO fatigue test standard of the first tube. The whole test system is automatically controlled by the program. The force application system adopts force closed-loop control.

According to the standard: ISO 4210-6:2014 4.4

Iii. Test method:

1) During the test, the frame is fixed on the test machine according to the method specified in the standard, and the position of the false front fork can be manually adjusted to adapt to the size of the frame;

2) Fix the frame and false front fork on the loading front axle, and fix the rear hook claw on the rear axle, and lock the rear axle fixing block.

3) Fix an adjustable part to prevent loosening during the test and affect the test.

4) Set the test force value and number of test requirements on the computer.

5) Adjust the maximum deformation of the front fork of the frame, and the machine will alarm and automatically stop the test after exceeding this deformation;

6) 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) Sensor capacity: 5000N

2) Load element resolution: 1/10000

3) Test force: 600N-1200N configurable (force closed loop control)

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

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

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

7) Loading mode: pneumatic loading

8) Equipped with false frame front tube, in line with standard test requirements. During the test, it is fitted with the first bowl group.

9) Adjust the position of the locking screw selection of quick disassembly, easy to operate, adjust the position using the lead screw adjustment.

10) Shutdown conditions: the gas supply pressure is too low, the specimen deformation is large, and the stroke of the cylinder exceeds the set value

11) Equipped with independent electric control box

12) The front axle is equipped with bearings, small friction, small impact on the test.

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: Airtek

16) Power supply: 220V 5A

17) Air source: pressure 0.7MPa gas flow 200L/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.

Five, five, equipment details:

1) One PLC control cabinet

2) One host

3) A set of fixtures

4) A copy of the manual

5) One certificate of qualification

6) A warranty card
