Definition: Power tool that tightens and loosens bolts and nuts.
Classification of electric wrench
A power wrench is a power or battery powered wrench and is a tool that tightens bolts. It is mainly divided into impact wrenches, torsion wrenches, constant torque wrenches, angle wrenches, angle wrenches, hydraulic wrenches, torque wrenches, and rechargeable electric wrenches.
Application of electric wrench
Electric wrenches are mainly used in the steel structure installation industry. They are specially designed for installing steel structure high-strength bolts. High-strength bolts are used to connect steel structure joints. They are usually formed by bolts. High-strength bolts can be divided into torsional shear type and large hexagonal type. The national standard torsion-shear type high-strength bolts are M16, M20, M22, and M24. Now, there are also non-national standard M27 and M30; the national standard large hexagonal high-strength bolts are M16. , M20, M22, M24, M27, M30 and so on. In general, the tightening of high-strength bolts must be tightened first and then tightened tightly, and each step requires a strict torque requirement. The initial tightening of the torsion-shear type high-strength bolts can use impact electric wrenches or constant-torque wrenches, and the tightening wrenches must be used for the final tightening; the tightening and final tightening of large hexagonal high-strength bolts must use constant-torque wrenches. Therefore, all kinds of electric wrenches are For a variety of fastening needs.
Use of electric wrench
The impact wrench is mainly used to tighten the bolt. Its use is very simple. It is to align the bolt to move the power switch. The electric torsion wrench is mainly a tight twist-shear type high-strength bolt. Its use is to align the bolt to move the power switch until the Torx-type high-strength bolt is interrupted by the Torx head. The electric torque wrench can be tightened tightly and tightly. Its use is to adjust the torque first and then tighten the bolt. The electric angle wrench is also mainly a kind of constant torque wrench. Its use is to adjust the degree of rotation first and then tighten the bolt. The electric angle wrench is an electric wrench which is used to fasten bolts at the corners of the steel frame. Its use is the same as that of the electric torsion wrench.
