Next, test machine Lao Er will tell you some common sense about universal material testing machine, hoping that it can help you better operate universal material testing machine in the future.
1. Universal Material Testing Machine Working Principle
Universal Material Testing Machine is also called universal tension machine or electronic tension machine. The second tester believes that its working principle is that the motor is controlled by a servo system. The motor drives the screw to rotate through a series of transmission mechanisms such as a reducer, thereby achieving the purpose of controlling the movement of the cross beam.
2. Universal Material Testing Function What items are tested?
Testing Machine Lao Er believes that the testing items of universal material testing machines are mainly ordinary and special.
General class:
Tensile stress, tensile strength, pull-break strength, pull-break elongation, fixed-extension stress, fixed-stress elongation , fixed-stress force value, tear strength, arbitrary force force value, arbitrary point force value, elongation at any point, pull-out force, adhesive force and peak calculation value, pressure test, shear peel force test, bending test, pull-out force puncture force test
Special class:
Elastic coefficient, proportion limit, Elastic limit, elastic deformation , permanent deformation, yield point, yield strength , spring K value, effective elasticity and hysteresis loss
3. What operating procedures are there for universal material testing machines
In order to ensure the accuracy of the test data, it is necessary to conduct mechanical performance tests according to the operating procedures of the test instrument. The second test machine simplifies it into the following steps:
1. Connect the power supply and wait for the system to enter the standby interface.
2. Press the "Detection key" to select the corresponding test type according to the system display.
3. Press the corresponding number key, then press the confirmation key to enter the universal material testing machine test system; enter the test piece number in the current dialog box, confirm and save the label; then enter the selection interface of variety number, enter the number of test pieces according to the system display, confirm and save; enter the test variety number to select the test material variety, press the confirmation key, and the system displays the "Test System Dialog Box". Enter the material variety, number, press the confirmation key, enter the test piece diameter (or area of test piece) in the dialog box displayed by the system, confirm, and enter the test interface.
4. Turn on the motor switch, start loading, observe the force value (or displacement, peak value) and rate at the same time, and press the range key to switch the force value range.
5. When the test is broken, the test is completed and the test data is automatically printed.
or above is the explanation of the working principle, testing project and operating procedures of the universal material testing machine. If you want to know more about the testing machine: principle, performance, parameters, usage, inspection, operation, measurement, maintenance, technology, three-dimensional diagram, assembly drawing, structural diagram, schematic diagram, mechanical diagram, exploded diagram, circuit diagram, etc., welcome to chat with the testing machine in the background, and the testing machine can provide you with free consultation.
