8 Steps of Impact Test for Luggage Oscillation Impact Tester

The luggage oscillation Impact Tester is mainly used to test the luggage handle, stitching and overall structure of the oscillation impact resistance test. The impact hammer is mainly used to rub the spreading leather specimen once, and the specimen with the surface damage caused by the rubbing is put into the observation box to compare with the standard specimen and determine the impact resistance of the specimen. Test comparison results are used to test the quality of bags.

 

 

1, when the impact pendulum is free to hang, the gap gauge placed between the sample table and the impact hammer, raise the sample table, so that the impact hammer, gap gauge, sample table contact, then record the reading r1 on the micrometer, the sample table down to a lower low position, and remove the gap gauge.

 

2, the impact pendulum to one end, with a fixed clamp.

3, the specimen has the head and neck mark one end fixed to the specimen table, use face up, and make the specimen in the specimen table flat stretch to the other end is clamped by iron, iron clamp one end with a line connected to the pulley, the pulley hanging 50N weight to pull tight specimen (pig, sheep clothing leather then use 25N weight).

 

4, the impact of the pendulum down free down, gradually raise the specimen table until the specimen and impact hammer contact. Note that the pressure is not applied. If the impact hammer and the sample is very obedient to the full area of contact, then record the micrometer reading r2, generally due to the sample surface is not flat or uneven thickness, the beginning of only part of the sample and impact hammer contact, then slowly rise the sample table, until the sample area of half of the contact with the impact hammer, stop rising sample table, and record the micrometer reading r2.

 

5, lower the sample table, so that the impact of the pendulum swing to the vertical surface of the position of 75 ° angle, with a fixed clamp, the use of micrometer to raise the sample to the following height: that is, when the impact of the pendulum fall, the impact of the hammer can penetrate the sample thickness of 3 / 10, with the positioning screws to clamp the sample table, at this time, the micrometer reading should be r2 + 0.3 (r1 + 0.5-r2), r2.

 

6, release the fixed clamp, so that the impact pendulum quickly impact the specimen. Only impact once that stop.

 

7, loosen the positioning screw, drop the specimen table, the impact pendulum to the side with the clamp, remove the specimen.

 

8、Use the observation box to observe the impacted specimen.
