izod charpy impact testing machine
izod charpy impact testing machine
he series impact testing machine is used to test the performance of impact resistance under the live load, being an
indispensable device in metallurgy and machine manufacturing units and is also a necessary testing instrument for the
research of new materials in research institution.the series model is the mostly widely used impact testing machine at
current market.
Technical characteristics:
1,Microcomputer control,electric rising pendulum,impact, results are measured
calculated by microcomputers and displayed digitally and printed out; having high operation efficiency, high testing
accuracy.the energy which is remained after the specimen is impacted broken can automatically rise the pendulum for
the next testing,simple operate and has high working efficient,the materials impact absorbed energy,impact elasticity and
pre-rising angle of pendulum and average value of test can be calculated and displayed,The test data and average value of
the time can be printed
2.The principle machine of the testing machine has single column structure,
Cantilever type pendulum hanging mode;the pendulum body is U-shaped.
3.The impact cutter is installed and fixed by screws and is convenient and easy to replaced.
4.The specimen is supported via simply by supported beam
5.Safety guard pin is arranged on the principle machine which is also provided with safety guard net.
6.The testing machine is controlled in a semi-automatic way,electric control is realized for pendulum rising,pendulum hanging,impacting and pendulum placing,The
energy which is remained after the specimen broken can automatically rise the pendulum for the next testing,thus,the
testing machine is suitable to be used in laboratories which make consecutive impact tests or the metallurgy and machine
manufacturing sectors which are involved with a large of impact tests.
7,The testing machine is in conformity with the international standard GB /T3803-2002 Testing of Pendulum Impact Testing Machine,and the impact test for metal materials is carried out according to
international GB/T229-2007<Metal Charpy Notch impact testing method>
