1. Application
JBDW-CY type impact testing machine is used for measuring the metal material resistance performance under dynamic load, in order to determine the material properties under dynamic load.It's a necessary testing machine, not only used in the metallurgy, machine manufacture etc areas, but also used for the science research.
2. Description
The equipment is simple operate with High efficiency, Yang pendulum, hanging swing, feeding, positioning, shock and temperature adjustment settings are controlled by a microcontroller, equipped with special feeding device automatic feeding, automatic sample face orientation. Sample baked to impact time is less than two seconds, meet the requirements of low-temperature metal Charpy impact test method.  It can use the remaining energy to automatic Yang pendulum after impact the sample, prepare for the next test preparation, high efficiency.
3. Features
3.1 Main frame is dual prop, shaft simply supported beam supporting, hanging pendulum, a reasonable distribution of radial load bearing host stiffness, particularly suitable for large energy impact test
3.2 Standard dual-stage reducer mention hammer, smooth operation
3.3 Hanging pendulum device using buffer device, hanging pendulum steady
3.4 Pendulum 3D design, to ensure the combat center accurate, precise moment the pendulum.
3.5 Shock knife with screw mounting, easy replacement.
3.6 Main frame is equipped with safety pins, and is equipped with a fully enclosed safety net.

6. Main frame structure and working principle
1 Low temperature device
Using liquid nitrogen cooling, temperature control are electrical control, equipped with special devices to send samples automatic feeding, automatic face orientation sample, to ensure the time is less than two seconds while Sample the cryostat to impact,Meet the requirements of low-temperature metal Charpy impact test method.
2 Feeding mechanism
2.1 After the sample is cooled at a low temperature to the desired temperature in the apparatus, quickly and reliably to the support surface of the anvil of this mechanism is accomplished.
2.2 Pneumatic cylinders are mainly constitute with feeding mechanism, feeding device composed.Feeding device is moved by compressed air into the cylinder to push the piston driven by the feed lever forward quickly reset feeding and backward linear motion .
2.3 The electrical signals of the feed lever forward, backward, stop, etc is emitted by  feeding the cylinder valve pneumatic, the magnetic switch, to control the cylinder forward, backward. Adjust the position of the magnetic switch, can fine-tune the position of the feed lever.
7.Measurement and Control section
7.1 Record impact strength,  impact energy etc. Also calculate the average of the maximum and minimum. 
7.2 The test data can be processed automatic, Automatic measure the cycle swing.
7.3 It has perfect Data analysis, Suitable for all types of complex data analysis to the user.
7.4 It has Complete operating system file, test report, test file etc.
7.5 The data can be stored as ASC, also can be reprocessed by any business report, word processing software.
7.6 The software support Multiple pendulum.
7.7 The test data can be statistic analysis automatic after test.
7.8 The report editing is flexible, Software offers a variety of report printing interface. (Excel, Word)
7.9 Interface display and control system.
