Precautions when using torque wrench

Everyone is familiar with torque wrench, torque wrench is the main role of the fastening bolt, torque wrench into our digital torque wrench, dial torque wrench preset torque wrench, electric torque wrench, then we should know the torque wrench in use Pay attention to what issues can reduce errors, users who do not understand quickly hurry to see it.

Torque wrenches have a wide range of applications. When the torque is tightened, it is only necessary to set the required value to be able to operate. It is relatively simple.

1. In the use of torque wrenches, we must first select the moderate range according to the requirements of the measurement parts. The measured torque value can not be less than 20% of the span of the torque wrench in use. Too large range should not be used for the reinforcement of small torque parts. Small-scale torque wrenches can't be used over-range.

2. When using a torque wrench, first connect the force pawl to an auxiliary accessory (such as a sleeve, all kinds of batches of mouth), to ensure that the connection is no problem. Before tightening the torque, set the required reinforcement value, lock the locking device, and then adjust the direction change button to the direction of the force.

3. During the measurement, the hand must grasp the effective range of the handle, and slowly increase the force along the direction perpendicular to the body until the sound is heard after reaching the set value. During the exertion of force, in accordance with the norms governing instrument regulations in the country, the verticality deviation should not exceed 10 degrees. The vertical deviation in the horizontal direction should not exceed 3 degrees. In the course of use, the controlling personnel should ensure that the range of up, down, left and right exertion does not exceed 15 degrees.

4. In order to prevent the measurement result from being affected by horizontal and vertical deviations, the force should be applied to the measurement. A vertical downward stabilizing force value is applied to the holder.

5, torque wrench readings: 1. If it is with a torque meter instrument. Reading the data directly indicated by the pointer is the measurement data value. 2. If it is a sleeve plus sub-scale indicator. The scale value on the main scale should be read first, and the sum of the scale values ​​on the sub scale or differential barrel should be the measured data value.

The company has manufacturing equipment and sophisticated inspection equipment, forming a fully functional, high-precision machining system and high-precision torque testing system. The company currently has a high-level, high-quality senior engineers, technical management personnel and production workers. The company's products are all produced by European and American professional torque tool engineers. When the company's products hit the Chinese market, it attached particular importance to the integration with the international modern enterprise management model. For quality, brands, and many factors that affect the development of Asia, Yasoh responded with a slogan: "Be the leader of China's torque tools and provide world-class torque tools!"
