This equipment is an instrument for testing the impact resistance of metal materials under dynamic loads. It can continuously conduct a large number of metal impact tests and adopts fully automated control. The control system uses an imported programmable logic controller (PLC) to control the entire process of swing and impact testing through microcomputer software programs. This machine is equipped with an aluminum alloy protective cover, providing conditions for safe operation for users. It is an essential testing instrument for metal material manufacturers and quality inspection departments, and also an indispensable testing instrument for scientific research institutions to conduct new material research.

Main functions:
1: The integrated design and casting processing of the main frame have high stability and good rigidity. The base is made of solid steel plate and weighs 350kg. The pendulum shaft is supported by a simply supported beam, which has a simple and reliable structure, high machining accuracy, low energy loss, and no shaking when the pendulum swings, making it suitable for high-energy impact.
2: The hanging and detaching device adopts a buffering design, which avoids the impact and possible damage during hanging, effectively reduces the noise during hanging, prolongs the service life of the equipment and improves safety, and ensures accurate pre swing angle of the pendulum. The hook mechanism is easy to disassemble and can be adjusted in its installation position on the pre elevation angle adjustment plate according to test requirements. By adjusting the pre elevation angle of the pendulum, the impact energy and impact velocity of the pendulum can be adjusted.
3: The transmission system adopts a servo motor system, which can accurately control the pre tilt angle of the pendulum and accurately stop the pendulum at any angle, thus testing the pendulum at any angle. The standard two-stage reducer replaces the complex transmission system of the old-fashioned pendulum, with a simple structure, easy assembly and maintenance, long service life, low failure rate, and maintenance free. The reducer is connected to the swing shaft through a dedicated electromagnetic clutch, which has the advantages of high torque, low noise, and fast response speed.
4: The angle acquisition adopts the Japanese NEMICON high-precision photoelectric encoder, with an angle resolution of up to 0.025 °. Ensuring the accuracy of equipment impact energy.
5: There are three types of energy display devices, one is a dial and the other is a text display. Computer software can also display energy values. If it is a single dial, it may occur that the pointer is forgotten to return to zero before the test, resulting in the sample being invalidated. If it is a single text display method, it is impossible to determine the accuracy of the data when the encoder encounters an error. The machine displays three methods together, and the results can be compared with each other, which can effectively eliminate possible problems.
6: The fully enclosed safety cover effectively prevents the splashing of fractured specimens and also prevents testers from entering the interior of the testing machine during testing. The interlocking door limit switch prevents misoperation and ensures the safety of test personnel. The protective cover frame is made of aluminum alloy profiles, embedded with organic glass for easy observation, and the left and right covers are door shaped structures for easy equipment maintenance and adjustment of the hanging mechanism.
7: The pendulum is designed in combination and can switch between two maximum energies of 300J and 450J. A pendulum can simultaneously meet two maximum impact energies, eliminating the need for customers to frequently replace the pendulum.
8: Customers can replace different impact blades according to their testing requirements. This combination pendulum can be equipped with multiple impact blades, such as R2 blades that meet ISO and GB standards, R8 blades that meet ASTM standards, or R2 or R8 impact blades with force sensors (instrument based impact configuration), and cantilever beam blades that meet ASTM E23-07a standards. A pendulum can be equipped with multiple blades simultaneously to meet various testing methods, eliminating the need for customers to frequently replace different types of pendulums.
9: This device can be equipped with multiple impact supports. Customers can replace different impact supports according to different testing methods, such as simply supported beam impact supports (standard) and cantilever beam impact supports
