Precautions and maintenance methods for the use of metal tensile testing machine

The metal tensile testing machine is used to detect mechanical properties such as peeling, tearing, bonding, opening, stretching, deformation, heat sealing, puncture, pulling, pulling, pulling force, etc. of wires, cables, food, aluminum-plastic pipes, films, paper, mechanical manufacturing, porcelain, pharmaceutical packaging, geotextiles, wood, metal materials, etc. How much do you know about metal tensile testing machines? Today I will introduce to you the precautions and maintenance methods of metal tensile testing machines. Let’s take a look.

1. Precautions for the use of metal tensile testing machines

1. During the use of the metal tension test machine, it must ensure the smoothness of the gears and prevent dry transmission during the movement. As time goes by, it will increase wear and tear. Too much smooth oil will also stick to a lot of dust, so it is essential to ensure the cleanliness and hygiene of the operating room of the metal tension test machine.

2. What are the smoothness and oil discharge of the metal tensile tester? The top of the base of the main body is equipped with an oil injection hole, which is smooth. Through this hole, the nut is smooth, and the threads of the screw are used for lifting and landing of the lower jaw seat.

3. The application situation should be usually smooth to prevent wear and transmission. After the main device is completed, the oil probe needle is passed through the seat hole of the oil probe needle on the top of the base, and the engine oil is injected into the oil pool with a funnel. The oil depth is 30 mm, and it is measured with the oil probe needle.

2. Maintenance method of metal tensile testing machine

1. Before the test, the system must be preheated for more than 20 minutes to minimize the temperature impact;

2. The oil used for the buffer should be kept clean. If the oil level is less than two-thirds of the depth of the cylinder, it should be replaced immediately;

3. Before starting the machine, check whether lubricating oil should be added to the frictional moving parts;

4. Before adding the test piece, the metal tensile tester must jam the brake handle, and release it after adding the test piece;

5. Refueling is not allowed on the main bearing of the dynamometer. The surface of the friction wheel in the gearbox must not be refueled or oil stains splashed. The friction surface should be absolutely clean and the inclined block on the swing arm must not be violently impacted;

6. After the test is completed, after the power is cut off, the test machine will be cleaned and protected in a timely manner;

7. The tensioner is maintained twice a month on average.

Before using any test machine, everyone should have a good understanding of the product to better achieve human-machine running-in during operation. This improves production efficiency. In summary, the above is an introduction to the precautions and maintenance methods of the metal tensile testing machine. I hope it can be helpful to you.
