1. The impact principle and life of the cantilever beam Impact Testing Machine.
The cantilever beam impact tester is used to determine the impact toughness of non-metallic materials such as plastic, reinforced nylon, glass fiber reinforced plastic, ceramics, cast stone, plastic electrical appliances, and insulating materials. Pendulum impact testing machine is a common equipment for quality inspection by scientific research units, colleges and universities, and non-metallic material manufacturers. The machine is a simple structure, easy to operate, and high precision instrument. The digital display impact testing machine adopts high precision. Encoder technology has the characteristics of high accuracy, good stability and large measuring range. The digital measurement shows the impact strength and average value, the energy loss is automatically corrected, and the test report is printed.
The impact principle of the cantilever beam impact testing machine is relatively simple, mainly through the impact force of the pendulum hammer to achieve impulse on the surface of the material, thereby causing damage. During the test, the pendulum is hung on the arm of the frame, and the pendulum is freely dropped to break the material placed on the support. When it rises in the reverse direction, push the pointer and read the break test from the reading of the dial. In this way, the energy consumed can be used to calculate the impact strength.
The Cantilever beam impact testing machine is a new type of impact testing machine which can measure and record the characteristic curve of material in the process of impact instantaneously. By replacing the pendulum and the sample base, two types of tests of simply supported beam and cantilever beam can be realized. It detects the angular displacement signal and sends it to the computer for data processing. It has high accuracy and is widely used in electronics, plastics, hardware, luggage, handbags, furniture and other industries.
2. How to extend the service life of the pendulum impact testing machine
In order to prolong the service life of the pendulum impact testing machine, I hereby remind users and friends that when using the pendulum impact testing machine in the later period, we must pay attention to regular inspection and maintenance of the equipment, the purpose is also to ensure the accuracy of the test. The specific maintenance work of the pendulum impact testing machine are as follows:
(1) Regularly check whether the bolts at the connection of each part of the equipment are loose, and the connection must be tightened;
(2) Regularly clean and maintain the equipment to ensure that the equipment is clean, well lubricated, and anti-corrosive;
(3) Do an air strike test. When the pendulum is idling, the test reading must be zero;
In short, when using the pendulum impact testing machine daily, only by ensuring the flexibility and accuracy of the pendulum and other motion mechanisms, can the equipment's working capacity meet the specified requirements, which will play a major role in ensuring the accuracy of impact testing and prolonging the service life of the equipment.
