Nucor Steel (USA)

2017.06.29   WANCE

Model: PIT503E

Maximum impact energy: 5000J

Standards: ASTM E604, GB/T 5482

Functions:

This type of testing machine is specially used for dynamic tear testing (DT test) of metallic materials.

Features:

1.     Automatic control: specimen feeding, impacting, pendulum raising and specimen collecting can be fully automatically operated.

2.     Heavy duty seat and frame ensures stiffness and accuracy, reducing shock after impact. Seat is made of high strength carbon steel, frame is made of H shape 300# steel. Specimen anvil is made of 45# forged steel with quenching and tempering treatment, ensuring high strength and stability.

3.     High strength pendulum body ensures stiffness in axial and transverse direction. Pendulum consists of pendulum body, arm, hook and striking knife. Arm is made of 45# steel and then machined to H shape. Body and arm is treated with quenching and tempering. Striker knife is made of tool steel with hardening treatment and hardness can reach 62HRC.

4.     Three types of pendulum raising device provides three types of impact energy without changing pendulum.

5.     Driving system

Use motor to raise pendulum with constant torque output and precise raise. 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.
