Pendulum impact testing machine

Brand:

WANCE

Country:

China

Application:

  • Impact on metals, Charpy and Izod, both non-instrumented and instrumented
  • Wedge impact test of adhesive bonds
  • Brugger method test of toothed gear wheels
  • Servo motor driven pendulum can stop at any position, realizing different angle/energy impact test for R&D use
  • Equipped with cooling system, I can perform low temperature test down to -180℃

Standards
ASTM E23, ASTM E1820, ASTM E2298, AS 1544, ISO 148, EN10045, ISO 14556, ZF 15-53, ISO 11343, JIS Z 2242, JIS B 7722, GOST 9454

Machine structure
The basic model consists of a heavy solid steel base on which the specimen holder (anvil) and a heavy-duty cast steel upright are mounted. The machine is constructed with main frame, driving system, pendulum lock/release system, angle encoder, display, protection shield and other accessories.

Pendulum
3D CAD software provides advanced design and analysis, ensuring accurate striking point and pendulum moment. High stiffness pendulum rod ensures no vibration after impact.
Customer can change striking knife according to test standard requirements, such as R2 for ISO/GB standard, R8 for ASTM, or R2/R8 instrumented knife, or Izod knife complying with ASTM E23.
300J and 450J pendulum is a combined design. It consists of 300J pendulum, and two counter weights. It can reach 450J when assembling 300J pendulum head with two counter weights. This flexible design facilitates switching impact energy, simple and high efficiency.

Charpy support & anvil
Standard configured Charpy support and anvil comply with ISO148, EN10045, and ASTM E23.
Smart design of anvil is easy to assemble, simplifying maintenance.

Optional multi-purpose fixture (patent pending)
Wance patented design of multiple purpose fixture is able to perform Charpy, Izod and tensile impact test without changing the specimen fixture, greatly reducing the labor and improving efficiency.
There are two types of fixture:

  1. Manual type: manually center the Charpy specimen, manually clamp the Izod specimen.
  2. Pneumatic type: pneumatic cylinder is used to center Charpy specimen, and to clamp Izod specimen.

Pendulum holding & releasing mechanism
It features damping design during pendulum holding to prevent any damages, lower noises and improve durability and safety.

Driving system:
This series adapts standard double speed reducer instead of old complicated driving system, featuring simple structure, easy repair, and high durability and free of maintenance.

Angle measurement system
Japanese made NEMICON high precision optical encoder is used for angle measurement, angle resolution can reach 0.025° to ensure high accuracy of impact energy.

Safety system:
This series of machine has fully closed protection shield to protect operator against specimen splitting during test, and to deny any access to the inside during test. Built-in door interlock further ensures operator safety. The protection shield is constructed with aluminum alloy profile for frame and fiber glass for easy observation. Split-type door design is simple to repair and change pendulum.

Energy display system
Three types of energy display are available:

  • Analogue: simple and direct to read impact energy
  • Wide view touch screen
  • Computer software

Instrumented impact system – IIS105
Instrumented impact system consists of striking knife with force transducer, data sampling card, signal conditioner and professional test software. Instantaneous force signal from transducer assembled on the striker is transferred to and enlarged by high speed signal conditioner. Enlarged signal is A/D converted by high speed data sampling card, then transferred to computer for storage and analysis. After calculating and analyzing original force vs. displacement curve, more characteristic parameters could be determined, furthermore specimen deformation and fracture property could be precisely judged.

Instrument data analysis system – Software

  • Automatic curve fitting of force vs. displacements
  • Automatically determine Fgy, Fm, Fiu, Fa, and other characteristic parameter, further determine after calculation Sgy, Sm, Siu, Sa, St, Wm, Wiu, Wa, Wt and others.
  • Fully automatic data processing permits to get test results and report after each test immediately.
  • Curve and raw data can be exported
