MODEL JBDW-750C-196Z
COMBINED COMPUTER CONTROLLED
LOW TEMPERATURE C-TYPE
FULLY ENCLOSED AUTOMATIC PENDULUM IMPACT TESTING MACHINE
Brief introduction:
The machine can
be used for the determination of anti-impact performance of metal
materials when it is under dynamic loading, thus judged the quality
of materials under dynamic loading. It is applicable for the
laboratory, which does continuous compact tests, metallurgy,
machinery manufacturing, and other industries.
Main features
-
It adopts
computer control, electric swing, impact, computer measurement,
calculation, screen digital display and printing, etc., with
high work efficiency and high test accuracy. After impacting the
sample, the residual energy can be used to swing automatically
to prepare for the next test. The operation is simple and the
work efficiency is high. In the continuous impact test
laboratory and a large number of impact test metallurgy,
machinery manufacturing and other industries, its advantages can
be more reflected. The computer can calculate and display the
impact absorbed energy, impact toughness, pendulum angle and
average value of the test, and print the data.
-
The main
machine is
supported by double supports. The main shaft is supported by
simply supported beam, and the radial load distribution of
bearing is reasonable. In particular, a large number of impact
machines can reduce the deformation of main shaft and greatly
reduce the energy loss caused by bearing friction.
-
It adopts
two-stage standard reducer to lift hammer and runs smoothly.
-
The hanging
and swinging device adopts hydraulic buffer, and the hanging and
swinging is stable.
-
The
three-dimensional design of the pendulum ensures the accuracy of
the strike center and the pendulum torque.
-
The impact
knife is fixed with screws, which is easy to replace.
-
After the
sample is broken, it can be judged automatically and output.
-
The main machine is
equipped with safety pin and safety net.
-
Combined with
both compressor & liquid nitrogen refrigeration methods.
-
The
impact test of metal material is carried out according
to national standard GB/T
3808-2002 “Pendulum
Impact
Testing
Machine”,
GB/T
229-2007 “Metal
