The tensile testing machine can test and analyze the mechanical properties of various metals, non-metals, and composite materials. It is widely used in aerospace, petrochemical industry, machinery manufacturing, wires, cables, textiles, fibers, plastics, rubber, ceramics, food, pharmaceutical packaging, aluminum-plastic pipes, plastic doors and windows, geotextiles, films, wood, paper, metal materials, and manufacturing industries, the electronic tensile testing machine can automatically calculate the test force value and fracture according to GB, JIS, ASTM, DIN, ISO, and other standards.
Test data such as force value, yield strength, upper and lower yield strength, tensile strength, compressive strength, elongation at break, tensile elastic modulus, bending elastic modulus, etc.
Let's take the metal material tensile test as an example to introduce the operating steps of the metal material tensile testing machine when stretching the sample:
1. First check whether the data cables and power cables are connected normally, open the control computer and start the testing machine measurement and control software, edit the test data, then press the "power" button of the control cabinet, the indicator light will light up, and the oil pump motor will turn on. Don't rush to do the test at this time. You should preheat the oil circuit of the pump station system. After about 1 minute, you can start using it.
2. Install the corresponding jaws according to the diameter or size of the sample. A set of hydraulic press jaws is divided into 4 pieces, two upper and lower pieces. At this time, a small amount of molybdenum disulfide should be added between the jaws and the jaw splint for lubrication. fat.
3. When clamping the sample, one end of the sample should be clamped into the upper jaw of the testing machine first, then click the clamping button on the manual control box, then select the appropriate speed, and click the crossbeam up button to raise the middle crossbeam for clamping. With the lower shallow mouth. In this step, attention should be paid to the distance between the clamped sample and the shallow mouth. Generally, the clamped sample should be two-thirds of the clamped jaw.
4. Select the appropriate test speed in the measurement and control software of the control computer, clear the force value, displacement, time, etc., and then click the test button. At this time, the curve on the display screen begins to be drawn and the test begins.
5. As the test force increases, the test curve will also show an upward trend with the force value until the curve begins to decline after the metal material yields. At this time, it indicates that the sample is about to break. Please observe until the end of the test.
6. After the test is completed, the experiment report will pop up automatically. Select the required test results to print and save.
The above are the operating steps of the metal material tensile testing machine when it is stretched. If it is doing a compression test or a bending test, its operation process is the same, because the universal material testing machine has a pull-up and down-pressure structure. As long as the compression or bending test is performed The same test results can be achieved by placing the assistive device in the lower space.
