China Automatic Charpy Impact Testing Machine

With the rapid development of material technology, to meet the requirement for high efficiency material testing, TIME JB-WE Series with full automatic control and high safety was born to meet this trend.
Application:
Full Automatic Impact Testing Machine was widely used in mechanical metallurgy, aerospace engineering, vessel building, academy and institute, and nuclear power engineering fields which has high requirement on temperature testing with high efficiency.
Features:
SIMENS PLC control. RS-232 Port data transmission
Auto feeding & specimen placing system adopt Japan made pneumatic components for high accuracy locating.
Omron (Japan) 3600 wires encoder resolution 0.1°, which is 10 times higher than common dial display impact tester.
Double-column structure increased machine stiffness greatly. Finite Element Analysis (FEA) was conducted for the whole frame. Pedestal of mainframe and upright stand are integrally cast, which ensures good rigidity and improves the stability of test. Double-column structure with reasonable radial loading distribution of bearing decreased the energy loss caused by the friction of bearing largely.
Worm & gear and decelerator motor system for pendulum rising. Special double-ring electric-magnet clutch torque can be up to 1000NM.
Fully-closed alum protective cover ensures the safety of operator and avoids the splitting of fractured specimen.

Specimen Auto Feeding System
JB-W-E Series impact testing machine equipped with specimen auto feeding system. 21 pieces U or V notched specimen can be placed in a line on specimen stand. Auto pusher will push the specimen one by one to temp. system. When temp. arrived at the setting target and up to the set time, system will push the specimen to impact anvil support. Single test or batch test can be set according to operator's need. For batch test, pendulum will run automatically when specimen is placed, and rise back to wait for another specimen till the end of 21 impacts.
