In the fields of steel metallurgy, pressure vessels, rail transportation, shipbuilding, and engineering machinery, the impact absorption energy of metal materials is a key indicator for measuring their toughness and resistance to brittle fracture, which directly affects the safety and reliability of engineering structures. The fully automatic impact testing machine series of Jinan Xinguang Testing Machine Manufacturing Co., Ltd. (hereinafter referred to as "Xinguang") provides high-precision, high-efficiency, and fully automatic testing solutions for the impact performance testing of metal materials at room temperature and low temperature.
Traditional impact testing relies on manual operation, which has problems such as time-consuming sample clamping, low low-temperature transfer efficiency, and easy data recording errors. The Xin Guang fully automatic impact testing machine adopts PC microcomputer control technology to achieve full process automation from swing, impact, measurement, calculation to result printing. It strictly follows national and industry standards in design and has the following outstanding advantages:
1、 Fully automatic closed-loop control, easy and efficient operation
The equipment adopts microcomputer control to achieve integrated operations such as electric swing, impact, measurement, calculation, screen display, and printing. After impacting the sample, use the remaining energy to automatically swing and prepare for the next test, especially suitable for laboratories with continuous batch testing. The control system supports automatic sample delivery and automatic end face positioning to ensure that the time from sample discharge to impact meets standard requirements.
2、 Multiple impact energies, covering the entire range of needs
The Xin Guang fully automatic impact testing machine can provide various impact energy specifications such as 150J, 300J, 450J, 750J, etc., to meet the impact toughness testing needs from conventional metal materials to high-strength alloy steels. The pre swing angle of the pendulum is 150 °, the impact velocity is 5.2m/s, the support span is 40mm, and it is suitable for standard Charpy V-shaped or U-shaped notch specimens.
3、 High precision measurement and control system, with real and reliable data
Equipped with high-precision angle encoder and measurement and control system, the test results are accurate and reliable. The equipment is controlled by a microcontroller or microcomputer, which can achieve integrated operations such as swinging, positioning, impact, measurement, calculation, digital display results, and printing, with high work efficiency and testing accuracy. The pendulum moment (impact constant) is 80.3848N · m (150J) and 163.7695N · m (300J), and the distance from the center of rotation of the pendulum to the impact point is 750mm.
4、 Scalable low-temperature module to meet diverse testing needs
The equipment can be equipped with a low-temperature device, using cascade compressor refrigeration technology, with a low-temperature range covering room temperature to -60 ℃ (expandable to -100 ℃), and a temperature control accuracy fluctuation of ± 1.5 ℃. Equipped with a dedicated sample delivery device and automatic end face positioning of the sample, ensuring that the impact time from the sample being taken out of the furnace is not more than 2 seconds, fully meeting the requirements of the metal low-temperature Charpy impact test method. The sample box has a capacity of 20 and can load test samples in batches. With the automatic sample delivery system, it can achieve continuous unmanned testing.
5、 Multiple security protections ensure worry free operation
The equipment is equipped with multiple safety measures such as overload protection, overcurrent protection, limit protection, and emergency stop button. During the experiment, operators and observers should be outside the safety cordon to ensure the safety of the experiment. The equipment adopts a three-phase 380V ± 10% 50Hz power supply. During installation, the foundation must be strictly laid according to the drawing requirements to ensure stable operation of the equipment.
6、 Intelligent software system, efficient data management
The measurement and control software adopts the Chinese Windows platform, with a beautiful and elegant interface. The test results can query and print various test curves and related data, and automatically generate testing reports that meet the standard requirements. The data supports exporting in various formats such as Word, Excel, PDF, etc., meeting the requirements of the laboratory quality management system.
The Xin Guang fully automatic impact testing machine complies with the following national standards and industry specifications:
-GB/T229 "Charpy Pendulum Impact Test Method for Metallic Materials"
-GB/T3808 "Inspection of Pendulum Impact Testing Machines"
-ISO148-1 "Charpy Pendulum Impact Test for Metallic Materials"
