Microcomputer controlled impact tester


用于测定金属材料在动负荷下抵抗冲击的性能,以便判断材料在动负荷下的性质,符合GB/T3808-2002和GB/T229-2007。 JB-S impact tester is used to determine the resistance of metal materials to impact under dynamic load in order to judge the properties of the material under dynamic load. This tester uses the way that the difference between the potential energy before the impact of the pendulum and the residual energy after the impact is displayed on the dial to obtain the absorbed work of the sample; the PLC-up controller is used to control the test process, which is simple and efficient High, the pendulum is automatically lifted by using the remaining energy after the sample is punched. The pendulum's back-lift angle is measured by the sensor. The work done AK value. Optional micro printer can print test data, including: AK value, impact toughness ak value, average work of three samples (AK / 3) and time and serial number. It is suitable for metallurgy, machinery manufacturing plants, pressure vessel factories, etc. that do a lot of impact tests. Note: The mini printer is optional.

main feature:

Significant software and operating system benefits
1. The LCD and dial display at the same time, data synchronization, equipped with dual display system, non-interference, flexible operation, high work efficiency.
2. Continuous testing can be performed on hundreds of samples continuously. The manual operation is only used to place the samples and press the action button. The rest of the work is fully automated by the testing machine, reducing labor intensity and completely eliminating the possibility of manual data recording errors. It is suitable for metallurgical industry and mining industry with large test volume.
3. Optional special function-rich pendulum impact test software, intelligent, menu-based operation, test operations such as pendulum removal, withdrawal, impact, and pendulum can be completed by clicking on the meter box.

Significant advantages of the electrical control section
1. Take imported PLC-uP controller as the core of electrical control system, and use high-precision photoelectric encoder as the angle acquisition sensor.
2. Integrated circuit board makes maintenance easier.
3. Replace the old-fashioned clutch with a brush clutch. In the test, the pendulum automatically takes the pendulum to effectively protect the clutch, reduce the system's damage to the clutch, and extend the life of the system.

Significant advantages of the mechanical part
1. Adopt foreign advanced host structure technology design, beautiful appearance, solid and durable, reasonable structure.
2. The highly rigid pendulum prevents the pendulum from shaking after impacting the sample.
3. The standard turbo reducer is adopted, which has high efficiency and completely avoids transmission failure.
4. The modular structure reduces the processing and assembly links, and the accuracy of the host is greatly improved.
5. The host base and column are integrated and designed for casting and processing, with high stability and rigidity.
6. Replace the old-fashioned mechanical limit switch with a photoelectric proximity switch, which improves the stability of the equipment and keeps the pre-lift angle constant.

Significant safety advantages: The semi-closed protective cover of high-strength material includes the entire trajectory of the pendulum, and at the same time, it prevents the splashed sample from splattering and hurting people, which minimizes the operator's misoperation Injury and safety.
