JB-W300A microcomputer controlled pendulum impact tester is mainly used to measure the impact resistance of metal materials under dynamic load, so as to judge the properties of materials under dynamic load. This machine conforms to GB/T3038-2002 pendulum impact testing machine test and GB/T229-2007 metal Charpy notch impact testing method The equipment takes pendulum, impact, pendulum and other actions can be automatically controlled, display mode is double-display: that is, dial pointer and computer display at the same time, and can print batch or successive impact absorption power. And impact toughness test results are compact and easy to operate. The maximum impact energy of the device is 300J and equipped with a 150J pendulum.

Two. Plan description:

The working principle of the equipment is to use a high-precision photoelectric encoder and a computer with special measuring and calculating software to detect the impact absorption energy and the impact toughness of materials by detecting the difference between the potential energy before and after the impact of the pendulum. The display is double display: pointer and computer display simultaneously. The computer can not only display shock absorbing power, impact toughness, but also automatically process test data and generate test report. The control of swing, withdrawal, impact and swing can be controlled manually by manual box or automatically by mouse input by computer program, and batch or successive control can be carried out. Print test results.

The equipment adopts Siemens PLC as the lower computer control, brand computer as the upper computer control, the upper computer program adopts VB programming, RS232 communication mode, completes the data exchange and instruction transmission between the upper computer and the lower computer, makes full use of the powerful functions of the PC for data processing, report processing and so on. The high accuracy rotary encoder with inner meter control is used to get the real-time position of the pendulum and obtain the impact absorbing power. It has the characteristics of reliable, stable and accurate data.
