دستگاه تست ضربه نیمه اتوماتیک Mitech سری MJB-B، حرکت آونگ را با موتور سروو کنترل می کند، می تواند برای مواد فلزی، غیر فلزی و کامپوزیت تحت مقاومت بار دینامیکی در برابر تست عملکرد باشد. استفاده از صفحه نمایش صفحه مکانیکی کلاسیک، پایداری را به ارمغان می آورد. عملکرد، عملکرد ساده، ساختار قوی، ساختار ساده، راندمان بالا. به طور گسترده در فولاد، لوله های فولادی و دیگر فلزات آهنی و آلیاژهای آن استفاده می شود که از عملکرد ضربه ضد آونگ آن برای اندازه گیری دقیق استفاده می شود. تجهیزات تست دقیق حرفه ای لازم برای بهبود راندمان تولید و صرفه جویی در هزینه های تولید است.
Function & application
It is widely used in the accurate determination of pendulum impact resistance of ferrous metals and alloy materials, such as steel, steel pipe, etc..
Working Principle
The hemispherical punches of the impact testing machine impact and pass through the specimen at a certain speed and measure the energy consumed by the punch to evaluate the impact resistance of the specimen.
Working Conditions
l Operation Temperature:Ambient temperature～45℃;
l Relative humidity:20％～80％;
l No vibration, no corrosive medium, no high magnetic field interference;
l Horizontal installation on a solid basis;
l Power supply voltage fluctuation does not exceed 10% of rated voltage.
Instrument Features
l It is widely used in the fields of metal and nonmetal processing, manufacturing, quality inspection, quality inspection, scientific
research and experiment in Institutions of higher learning and so on;
l Semi automatic control, swing, pendulum, impact, pendulum are electrical control, and automatic swing, high efficiency,
especially for continuous impact test;
l Novel shape, strong construction, high reliability, simple operation;
l Classic mechanical dial, intuitive reading, high testing efficiency;
l Using single support column structure, cantilever pendulum and U pendulum hammer, the performance is stable and the
measurement accuracy is high;
l The impact knife is fixed and fixed by screws, and it is simple and convenient to replace;
l Specimen simple supported, can quickly replace the sample, easy to operate;
l Equipped with safety protection pin and safety protection net to ensure test safety;
l Consistent with GB, ISO, ASTM and other relevant domestic and foreign standards.
Instrument Maintenance
l Read the manual carefully before using the instrument. Learn the operation steps and attentions to avoid damage the
instrument or personal safety accidents caused by improper operation;
l Test machine is a large precision instruments, should pay attention to water, moisture. Exposed workstations, upper and
lower beam parts and attached parts should be coated with anti-rust oil to prevent rust;
l It is forbidden to put samples before the pendulum hangs.Before placing the sample, make sure that the pendulum is stable
and the safety pin has been ejected;
l When using, should pay attention to check the jaw support, pendulum hammer, whether reliable fastening, in order to
prevent the test results inaccurate or accident;
l The pendulum shaft bearings on both ends of the factory has been the use of units without refueling, refueling, such as
repairing after cleaning with 1-2 drop of sewing machine oil or watch oil, Vaseline or other power bearing grease;
l If at a long time idle, at least once a week to prevent rust;
l After the test, the pendulum should be placed in the vertical position, and the handle push rod is placed in the braking
position;
