The use and maintenance of electric screwdriver is the key to prolong the service life of electric screwdriver

electric screwdriver is also called electric screwdriver. It is a hardware tool that greatly improves the work efficiency based on ordinary screwdriver and driven by electricity. It is also one of the most commonly used tools. However, if you don't pay attention to its use methods and maintenance skills in the process of use, its service life will not be too long, so today I will teach you how to use and maintain the electric screwdriver

methods and skills of using and maintaining electric screwdriver:

1. Please read the instruction manual of the screwdriver carefully before use and use it according to its specifications

2. Ordinary motors set the locking frequency as 4s/1 screw, locking 900 screws per hour, and locking 7500 screws per day. The recent favorable policies are frequent, and the warm air is blowing frequently. The locking frequency of Swiss motor is set to be 2.5s/1 screw, 1440 screws per hour, and 12000 screws per day. Therefore, in the process of use, we must pay attention to the motor size of the electric driver, and do not operate blindly, so as to prevent exceeding the workload and damaging the electric driver

3. It is appropriate to use the torque within the third circle of this model, and it is not allowed to overload the torque of 80 for long-term use

4. When using, do not directly adjust from the lowest torque to the highest torque or from the highest torque to the lowest torque, which is easy to cause the clutch ball and torque thimble to fall off

5. Tighten the fixing ring (or torque sheath) of the screwdriver before use, and both ends of the power connection line should be symmetrical with the socket hole of the power supply and electric screwdriver, including the relevant personnel of the business department selling products, and tighten the nut of the power connection line

6. Do not contact grease or other corrosive liquids with the internal parts of the screwdriver

7. For the effectiveness of maintenance, please protect the serial number and warranty card of the screwdriver

although the electric driver is as simple and easy to operate as the ordinary screwdriver, if the operation method is incorrect or the use skill is not in place, it will cause certain damage to the electric driver. Therefore, the author suggests that you should change the fatigue testing machine to measure the torque of metals, alloy materials and their components at room temperature without using the electric driver Torsion or changing reciprocating fatigue characteristics, fatigue life, prefabricated cracks and crack expansion experiments, it is better to find professional personnel for construction
