Charrpy impact testing machines Description and Specifications for Lab Tenders
Charrpy impact testing machines.
Charrpy impact testing machines
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 is 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
ISO 148 and ASTM E23
