دستگاه تست ضربه دستی Mitech MJB-300، حرکت آونگ را به صورت دستی کنترل می کند، می تواند برای مواد فلزی، غیر فلزی و کامپوزیت تحت مقاومت بار دینامیکی در برابر تست عملکرد باشد. از بلند کردن دستی، ضربه، صفحه نمایش صفحه مکانیکی کلاسیک استفاده می کند، عملکرد پایدار را به ارمغان می آورد. عملکرد ساده، ساختار قوی، ساختار ساده، راندمان بالا. به طور گسترده در فولاد، لوله های فولادی و دیگر فلزات آهنی و آلیاژهای آن 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;
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 Manual lifting, manual operation, suitable for a small amount of test;
l Novel shape, strong construction, high reliability, simple operation;
l Classic mechanical dial, intuitive reading, high testing efficiency;
l In line with GB, ISO, ASTM and other relevant domestic and foreign standards.
Instrument Maintenance
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;
