The XJJC - 5 Microcomputer Control Impact Testing Machine features a dual - operating system with computer control and LCD display. The instrument offers convenient human - machine dialogue, high accuracy, and can automatically display impact energy, calculate impact strength, compute the average impact strength of the entire sample group, and delete data. It has an electrically released hammer body. The whole machine is made of steel with good properties, and after time treatment, there is no stress deformation. It is used to determine the impact toughness of non - metallic materials such as hard plastic, fiber reinforced composites, nylon, FRP, ceramic, cast stone, plastic electrical appliances, and insulating materials. It is the quality inspection equipment for scientific research institutions, colleges and universities, and factories and mines.
Working Principle:
Strike the sample supporting the horizontal beam with the pendulum hammer of known energy, and destroy the sample by one shock of the pendulum hammer. The impact line is located in the middle of the two supports, to impact the energy difference between the pendulum before and after, to determine the energy absorbed by the sample when destroyed. The impact strength is then calculated according to the original cross-sectional area of the sample.
