JBW-300B microcomputer controlled pendulum impact testing machine

1、 Product Introduction:
The JBW-300B microcomputer controlled pendulum impact testing machine is a new product developed by our company in strict accordance with GB/T3038-2002 "Inspection of pendulum impact testing machines" and GB/T229-2007 "Charpy notch impact testing method for metals"; It is an ideal testing instrument for measuring the impact resistance of metal materials under dynamic loads. The device can automatically control actions such as swing, impact, and release, and the display mode is dual display: the dial pointer and computer are displayed simultaneously, and the test results such as impact absorption energy and impact toughness can be printed in batches or sequentially. The structure is compact and the operation is simple. The maximum impact energy of the equipment is 300J, and it is equipped with a 150J pendulum.

2、 Scheme description:
The working principle of this device is to use a high-precision photoelectric encoder and a computer with dedicated measurement and control software to detect the impact absorption energy and material impact toughness by detecting the difference in potential energy before and after the impact of the pendulum. The display mode is dual display: that is, the dial pointer and the computer are displayed simultaneously. Computers can display impact absorption energy and impact toughness, as well as automatically process test data and generate test reports. Actions such as swinging, retracting, impacting, and releasing can be manually controlled by a manual control box or automatically controlled by mouse input using computer programs, and test results can be printed in batches or sequentially.
The equipment adopts Siemens PLC from Germany as the lower computer control, and a branded computer as the upper computer control. The upper computer program adopts VB programming and RS232 communication method to complete data exchange and instruction transmission between the upper and lower computers, fully utilizing the powerful functions of the PC for data processing, report processing, etc. Using a high-precision rotary encoder controlled by internal meters to obtain the real-time position of the pendulum and obtain the impact absorption energy. It has the characteristics of system reliability, stability, and accurate data.
