Tensile testing machine, also known as universal material testing machine. The universal testing machine is a mechanical force testing machine used for static load, tension, compression, bending, shear, tearing, peeling and other mechanical performance tests of various materials and equipment. What are the characteristics of tensile testing machines? How to proceed with the operation? Below, the editor will provide a detailed introduction to these two issues for everyone, let's take a look together.
Characteristics of tensile testing machines
1. The tensile testing machine adopts advanced microprocessor control, which can perform digital input, digital display, program control, and data processing during the testing process.
2. The tensile testing machine has unique functions and is the only equipment in China that can complete the functions of two instruments with one instrument. Tensile testing can be conducted on heat shrinkable pipes, fittings, and hard plastic sheets.
3. The tension testing machine clamp has two sets of sample clamping devices, which can lift the drop hammer lifting mechanism and electromagnet with a length greater than 2 meters. This mechanism can lift the selected mass of the hammer body and hammer head to the selected impact height indicated by the height scale. Press the release button, and the hammer will impact the sample held by the gripper vertically below it with its determined energy. When the falling hammer rebounds from the sample, the capture mechanism with photoelectric control function of the instrument can timely and accurately capture the falling hammer.
4. Various operations of the tensile testing machine and the average height (h) of the falling hammer, as well as the increment of height（ Δ d) Average impact strength (E), number of specimen failures (or no failures)（ α) All parameters can be digitally input, displayed, and statistically processed, and can be used for product quality inspection.
Operation method of tensile testing machine
1. Select a suitable fixture based on the condition of the sample. If the fixture is already installed on the experimental machine, it needs to be checked. Colleagues set the limit device based on the length of the sample and the spacing between the fixtures.
2. Open the tension machine software, set up - online - com1, and proceed with the operation.
3. Click on the pre test settings item - Selection of sample data - Modify (select the corresponding experimental plan and input the original parameters of the sample, such as size and thickness)
4. Control scheme selection - modification (input testing speed and shutdown mode, etc.)
5. First, clamp the sample onto the clamp near the end of the force sensor, and after the force is cleared to eliminate the self weight of the sample, then clamp the other end of the sample to control the distance of the fixture by raising and lowering.
6. Start testing, the equipment will be tested according to the set plan, and after the testing is completed, save the test data
7. After the sample test is completed, the test results will be displayed on the right end of the screen. Click on Test Results - Test Results Selection - Click on Output Word Report to print or save the generated experimental report.
