Test procedure of falling ball impact testing machine

Ball Drop Impact Testing Machine The weight drop impact testing machine is suitable for testing the strength of plastic, ceramics, acrylic, fiberglass and metals. other materials and coatings.

The falling hammer impact testing machine adopts DC electromagnetic control method, the steel ball is placed under the electromagnetic suction cup, the steel ball is automatically sucked and the drop button is pressed, and the suction cup instantly releases the steel ball. Balls, steel balls will be used for the free fall test, impacting the surface of the specimen. The drop height can be adjusted up and down, and a height scale is attached to know the drop height of the coins. The key components of this machine are all made in Japan with reliable performance, and a variety of drop accessories make your test data productive.

Steps of the test

1. Determine the height of the falling ball based on the characteristics and size of the sample. After the height of the falling ball is determined, loosen the upper sliding sleeve to fix the steering wheel, adjust the height of the upper sliding sleeve;

Align the upper edge of the upper sliding sleeve with the waist of the scale (standard height of the drop ball + height of the sample), then tighten the upper sliding sleeve to fix the steering wheel.

2. Adjustment of the capture device:

Adjust the secondary anti-impact device so that the distance between the lower surface and the upper surface upper end of the sample is 40 mm.

The adjustment method is as follows: loosen the fixed wheel of the locking mechanism, after determining the size, tighten the fixed wheel of the locking mechanism.

3. Placement of the sphere:

First move the release handle to the ON position, push the flat end of the sphere up into the suction chamber,

4. Placing the specimen:

Place the specimen on the support jaw, adjust the fixed pressure blLock and firmly press the specimen with the ruler.

5. Testing process:

After the above work is completed, the ball drop impact test can be carried out.

First, take the sample out of the low temperature freezer and place it on the jaw of the percussion machine, move the release handle to the unlock position and the ball will fall freely upon impacting the sample.

Once the sample is impacted, the ball rebounds and enters the capture chamber. It is normal to have some discrepancies with the above process).

Then remove the round tube from the capture chamber.e, take out the sphere then insert the round tube from the capture chamber, press the reset button to reset the capture device and get ready for the next trial.
