Test principle: >
Use a hammer of known energy to strike the sample of the horizontal beam, and the hammer of the trial machine is shocked by a hammer to destroy the sample. The impact line is located in the middle of the two seats. If it is a gap sample, the impact line should be facing the gap to determine the energy absorbed by the sample when the energy of the front and rear hammers is poor. Then calculate its impact intensity according to the original cross -sectional area of the sample.
Put the characteristic parameters of the piercing test machine >Note: The results of the different hammers obtained Can't compare
The body is
The core part of the hammer impact test machine , it includes rotating shafts, swing rods and impact blade and other components Essence >The distance from the rotating shaft to the center of the hammer strike center should be consistent with the distance from the rotating shaft to the center of the sample. The difference between the two should not exceed the latter's ± 1%
The angle of the impact blade is 30 ± 1 °, and the radius radius of the end of the end is 2.0 ± 0.5mm. When the hammer hem, the blade must not exceed ± 0.2mm through the central deviation between the two seats, and the blade should be in contact with the strike surface of the sample. The contact line should be perpendicular to the long axis of the sample, and the deviation does not exceed ± 2 °.
Placing the hammer impact test machine use: > Hammer impact test machineAlso known as cantilever beam impact test machine is mainly used for hard plastic (including plate materials, pipes, plastic heterogeneous materials), enhanced nylon, glass fiber reinforcement, ceramic, cast stone, electrical insulation material, etc. The measurement of the impact toughness of metal materials is an ideal test equipment used by chemical industry, scientific research units, and colleges and universities for material performance testing.
> Put the hammer impact test machine
Features: > The parameters fully meet the requirements of ISO180, IOS2611, JB/T8761, ASTM D256 and other standards. Touch screen control, simple structure, convenient operation, accurate data, and miniature printing are several major features of this test machine.
