Operation method and characteristics of simple-supported beam impact test machine

The simple-supported beam impact testing machine is used to determine the impact toughness of non-metallic materials such as hard plastic sheets, pipes, special-shaped materials, enhanced nylon, fiberglass, ceramics, cast stone electrical insulating materials. How much do you know about the simple-supported beam impact test machine? Let me introduce the operating methods and characteristics of the simple-supported beam impact test machine.

1. Operation method of simple-supported beam impact test machine

1. Replace the appropriate pendulum according to the impact energy requirements before testing.

2. Turn on the power switch device and place the handheld operator to an empty (not a sample), check whether the passive dialing pointer refers to zero. If it is not a empty pointer, the position of the pointer should be adjusted, and the time and empty pointer is zero. Adjust the equipment before resetting the data displayed by the electronic test instrument.

3. Leaving the bearings at the edge of the swing block, the gap impact specimen notch supports the impact of the center, such as the impact of the notch.

4. Press the "Start" button to promote the pendulum, set high and stable on site, the shipped cleaning machine swings all obstacles, and the maximum energy scale dial pointer.

5. Press the "Test" button, hammer the sample, and write down the effect of energy after the pendulum stops swinging. After the test is completed, turn off the power operation and the impact of the machine power supply, bringing the operator back to the place.

6. Specific testing steps of simple-supported beam impact testing machine:

Raise the impact hammer to the alpha angle (150) and fix it to the fixing hook. The pointer is close to the pull rod, and the pointer should display 150 at this time. Press the fixed hook to allow the hammer to fall freely and push the sample. Reading index indicates the β angle sum record. Without samples, from the alpha angle, the hammer will affect the sum of the reading pointer indicating the alpha angle. There is no sample because the β angle will affect the hammer drop, read the pointer indicating the angle β and record. There is no sample, the effect of the hammer from the α angle. Do not move the cursor, so that the hammer will fall freely, and the pointer will rise again, repeat this way until the index does not move anymore; record the angle θ and record of the index.

2. Specific features of simple-supported beam impact test machine

1. The main unit of the test machine is a single-support column structure, cantilever hanging pendulum method, and pendulum hammer body U-shaped;

2. The impact knife is installed and fixed by screws. The simple-supported beam impact tester is simple and convenient to replace;

3. Sample simple-supported beam type support;

4. The main unit of the simple-support beam impact test machine is equipped with a safety protection pin and is equipped with a safety protection net;

5. The test machine is semi-automatically controlled, and the swing, hanging, impact and release are electrically controlled. It can use the remaining energy after the sample is broken to automatically swing and prepare for the next test. Digital display simple-support beam impact testing machine is especially suitable for laboratory rooms that perform continuous impact tests and metallurgy, mechanical manufacturing and other departments that perform large amounts of impact tests;

6. Digital explicit impact test machine: Use a single-chip microcomputer to control the usage method of the simple-supported beam impact test machine, and measure, calculate and display the results of the single-chip microcomputer. It can calculate and digitally display the impact absorption work, pendulum angle and test average value. Print the test data and the average value of the test. High working efficiency Simple-supported beam impact testing machine with high test accuracy.

After understanding the operating methods and characteristics of the simple-supported beam impact test machine, the operator must use it in accordance with the procedures and specifications of the instructions when using the test machine. Otherwise, it is easy to cause dangerous situations such as machine failure and personnel injury. If you have any unclear areas, please call us for consultation.
