1、Overview of this device:

The headphone stretching fatigue testing machine is suitable for testing the stretching fatigue strength of headphones and steel bars. This machine is used to place the two ends of the product on the clamping device with the adjusted test stroke, set the number of tests, and after reaching the set number, the machine stops working to check for product damage. This device complies with the General Technical Standard for Headphones GB/T14471, which tests the stretching fatigue of headphones.

2、Main technical parameters:

1. Testing station: one

2. Test speed: 5-60 times/minute (adjustable knob, LCD display)

3. Test count counter: 0-99999999 times (can be preset, automatically stops when the number of times is reached)

4. Unilateral travel: 0-150mm (manually adjustable)

5. Test stroke display: pointer indicating scale

6. Telescopic stroke: Adjustable eccentric shaft, movable test fixture

7. Machine size: 1000 x 400 x 600mm

8. Working power supply: AC220V, 50Hz

3、Product features:

1. The chassis of the retractable fatigue test for headphones is treated with electrostatic paint, designed and manufactured according to various products. The overall design is reasonable, the structure is tight, and the operation is safe, stable, and accurate;

2. The headphone stretching fatigue testing machine uses precision rods and linear bearings as the main operating body to avoid the unevenness of vertical inertia during slow speed testing;

3. The testing speed, frequency, stroke, and height of the headphone stretching fatigue testing machine can be adjusted, with a user-friendly design. Customers can set it according to their requirements.

4、Usage:

1. Preparation of products: First, confirm the testing frequency and schedule of various products, and prepare to test the products.

2. Clamping product: Place the product in the middle fixing rod, and secure both ends of the earphones with clamps.

3. Adjusting stroke: According to the opening and closing stroke of the product, use an Allen wrench to loosen the eccentric wheel adjustment device, adjust the expansion stroke, and then adjust the closing stroke through the adjustment fixture.

4. Set parameters: Connect the power cord, turn on the power switch, and set the number and speed of tests.

5. Start Test: Press the start button to start the test. The machine will clamp both ends of the product and conduct a simulated stretching fatigue test on the product based on the set stroke, speed, and frequency.

6. Test stop: The test will automatically stop after reaching the set number of times.

7. Record results: Record the test results and compare the products to obtain relevant quality information.

8. End of experiment: If the product needs to be replaced or the experiment needs to continue, the above steps can be repeated for operation. End the experiment, remove the product, unplug the power cord, and keep the machine clean.
