Description
Model:PIT**3
Type:Type E
Maximum impact energy: ***0J
Standards:
ASTM E**4, GB/T ***2
Functions:
This type of testing machine is specially used for dynamic
tear testing (DT test) of metallic
materials.
Features:
Heavy duty seat and frame ensures stiffness and accuracy,
reducing shock after impact.
2. High strength pendulum body ensures
stiffness in axial and transverse direction.
3. Three types of pendulum raising
device provides three types of impact energy without changing
pendulum.
4. Automatic control: specimen
feeding, impacting, pendulum raising and specimen collecting can be
fully automatically operated.
5. Apply servo motor as the power to
raise pendulum with constant torque output and precise raising.
Cycloidal-pin gear speed reducer directly drives clutch with more
advantages of simple structure, high speed-reduction ratio, high
overload resistance, high efficiency, and small size and easy to
maintain.
6. Equipped with specimen feeding and
positioning device provides rapid feeding, precise positioning,
high efficiency and safety, and reducing labor
intensity.
7. Equipped with pneumatic braking
device avoids clutch working at high speed, reduces clutch impact
abrasion, and extend its life.
8. Equipped with multiple energy
display device showing test results at the same time.
9. Equipped with specimen collecting
device, bring the tested specimen out of the machine. It allows
operator to collect specimen without going inside, greatly
improving efficiency and working safety.
*0. Full-closed safety shield prevents
splitting of cracked specimen. Limit switch on the door ensures
operator’s safety.
*1. Apply German Siemens S****0 series PLC
as controller. Full-automatic operation reduces labor intensity,
and improves working efficiency and safety.
