Functions

This   machine is used for measuring the Charpy impact resistance of metal and other   materials

Standards

ISO   148, EN10045, ASTM E23, GB/T 229, GB/T 12778, GOST 9574

Features

·          One-body cast frame design of seat   and column provide high stability and rigidity

·          Front and rear columns are   symmetrical. Pendulum arm is designed of cantilever beam support, with simple   structure and high machined precision

·          Apply high precision bearing with   small friction. Absorbing energy without loading is less than 0.3%

·          Double reduction gear system   replaces old style drive system with high efficiency and avoiding   transmission failure

·          Round pendulum head design reduces   windage losses to the most

·          High rigid pendulum arm prevents   axial and transverse vibrations

·          Exchangeable pendulum is simple to   change to satisfy impact energy of 150J, 300J, 450J, 600J, 750J

·          Electromagnetic release of pendulum   hammer and electromagnetic clutch for locking the pendulum and raising it to   its initial position. A damper is equipped to prevent strong bump when   clutching

·          Full-closed enclosure with high   safety to prevent broken sample from splitting. Protective screening has   interlock door. When the door opens, most operations can’t work to avoid any   wrong operation

·          Apply SIEMENS industrial PLC to   control pendulum, and high precision Japanese made NEMICON rotary encoder to   measure striker real time position. The whole system is stable, reliable and   accurate

·          A big touch screen monitor may   real-time displays striker angle, impact energy, toughness, and other   parameters.  User can input specimen   data and other information such as company information into this monitor.   When connected to a printer, user input information and test results will be   printed

·          Optional computer with software control   is available to realize semiautomatic operation. Operator only need charge   specimens. Others can be controlled by software

·          Optional specimen feeding system is   available. Combined with computer and software, fully automatic operation can   be realized

·          Optional cooling system is   available to satisfy cold specimen test down to -180℃

Specimen   collection and filtering device

·          Motorized   device is used for collecting broken specimens after impact, instead of   manual cleaning, which fully prevents striker from getting stuck

·          Unique   specimen filtering function: automatically judge and transport qualified and   unqualified specimens to different collecting box

Professional   test software

This   software is designed specifically for testing metals to Charpy standards.   Software provides an easy-to-use method for gathering, calculating and   storing impact test results. The test result can be printed and exported to   EXCEL for review.
