Electric wrench application field and use effect
? An electric wrench is a wrench powered by a power source or a battery. It is a tool for tightening bolts. Mainly divided into impact wrench, torsion shear wrench, fixed torque wrench, corner wrench, angle wrench, hydraulic wrench, torque wrench, rechargeable electric wrench. Application field of electric wrench Electric wrenches are mainly used in the steel structure installation industry. They are specially used to install high-strength steel structure bolts. High-strength bolts are used to connect steel structure contacts, usually in the form of bolt groups. High-strength bolts can be divided into two types: torsional shear type and large hexagonal type. The national standard torsional shear type high-strength bolts are M16, M20, M22, and M24. The non-national standard M27 and M30 are two types. , M22, M24, M27, M30, etc. Generally, the tightening of high-strength bolts should be tightened first and then tightened, and each step requires strict torque requirements. Both the initial tightening and the final tightening of the large hexagon high-strength bolts must use constant torque wrenches. Therefore, various electric wrenches come from various tightening needs. Use effect of electric wrench Impact electric wrenches are mainly for initial tightening of bolts. Its use is very simple, just align the bolts and pull the power switch. The electric torsion shear wrench is mainly for tightening the torsion shear type high strength bolt. Its use is to align the bolt and pull the power switch until the torx head of the torsion shear type high strength bolt is interrupted. The electric fixed torque wrench can be used for initial tightening and final tightening. Its use is to adjust the torque first and then tighten the bolts. The electric corner wrench is also a kind of fixed torque wrench. Its use is to adjust the degree of rotation first, and then tighten the bolt. The electric angle wrench is a kind of electric wrench specially used to fasten the bolts at the angle part of the steel frame. Its use is the same as the principle of the electric torsion shear wrench.
