Why is the universal tractor called "universal tractor"? How does it work?

Universal traction machine is also called universal materials testing machine or electronic traction machine, why is it called universal traction machine? First of all, the function of the tensile machine is to test the tensile strength, compressive strength, elongation and elongation of semi-finished and finished materials, and can be used for peel, tear, bending, bending, compression and other tests. In general, ordinary traction machines can only measure one or two or three kinds of materials, such as B. Rubber tractors, plastic tractors, metal tractors, etc., all of which have limitations. The materials tested by the universal pull function are very wide, such as B. Common non-metallic materials: plastics, textiles, waterproof materials, net ropes, etc., as well as metallic materials such as wires and cables, metal wires, metal plates, metal rods, etc. Machine for testing, so it is also called the universal traction machine. dZCTextile Testing Instruments, Testing Equipment Manufacturer

Universal traction machineOperation procedure and precautions: dZCTextile Testing Instruments, Testing Equipment Manufacturer

1. Turn on the main switch and turn on the power, turn on the Turn on the power switch of the universal tractor, check whether all parts of the machine work normally, and prepare for the test.
2. Before the test, the maximum load of the test should be estimated and a suitable sensor selected (imported sensors are recommended, with high precision, good repeatability, no zero drift and durable.).
3. Clamp one end of the specimen to the upper fixture, adjust the distance between the fixtures of the machine, adjust the lower jaw, and clamp the lower end of the test piece. Care must be taken to place the sample as vertically as possible and in the center of the device.
4. Charge according to the charging speed required for the testnity by adjusting the rotation speed of the loading speed indicator disc, and align the rotation speed of the loading pointer with the rotation speed of the indicator disc. Loading speed: before yielding - stress increase rate 10MPa/s after yielding - the moving speed of the moving chuck of the testing machine under load is not more than 0.5L/min. (Depending on different materials, different tests and different universal tractor models)
5. After the sample breaks, stop the motor.
6. Take a fracture sample, measure the elongation value and note it down as a basis for calculation.
7. Finally, disconnect the power supply, turn off the main switch and wipe and clean the device.
8. Compression and bending tests can be performed by referring to the above points (for reference only). dZCTextile Testing Instruments, Testing Equipment Manufacturer
