Introduction to the

Electric wrench is a power supply or battery - powered wrench, is a tightening bolt tools. It is mainly divided into impact wrench, twist shear wrench, fixed torque wrench, Angle wrench, Angle wrench, hydraulic wrench, torque wrench, charging electric wrench.

application

The electric wrench is mainly used in the steel structure installation industry, specially for the installation of steel structure high-strength bolts, high-strength bolts are used to connect the steel structure contacts, usually in the form of bolt group. High-strength bolts can be divided into two types: torsion shear type and large hexagonal type. The national standard torsion shear high-strength bolts are M16, M20, M22 and M24, and the non-national standard bolts are M27 and M30. Gb large hexagonal high-strength bolts are M16, M20, M22, M24, M27, M30 and other types. In general, the fastening of high-strength bolts should be firstly tightened and then finally tightened, and each step should have strict torque requirements. Fixed torque wrenches must be used for the initial and final tightening of large hexagonal high-strength bolts. Therefore, various electric wrenches are provided for various fastening needs.

Use effect

The impact electric wrench is mainly for the initial tightening bolt. Its use is very simple, that is, the power switch is pulled by aligning the bolt. The electric twist shear wrench is mainly for the high-strength bolt of the final tightening twist shear type. Its use is to pull the power switch on the alignment bolt until the torsion shear type high-strength bolt's plum head is interrupted. The electric constant torque wrench can be initially tightened and finally tightened. It is used to adjust the torque first and then tighten the bolt. Electric Angle wrench is also a kind of fixed torque wrench, its use is to adjust the degree of rotation, and then tighten the bolt. Electric Angle wrench is a special fastening steel frame Angle bolt electric wrench, its use and electric torsion shear wrench principle is the same.

performance

As the name suggests, the electric wrench is a necessary tool for tightening the torsion shear head bolts, which can help you install and remove the bolts and nuts and control the tightening torque more accurately at the same time. Using the fixed torque of the bolt, when the spanner reaches a certain torque, it can cut off the torque-head part of the bolt. Large torque, more reliable than manual insurance. Convenient, beautiful, practical, easy to carry with the car. Widely used in steel bridge, plant, power generation equipment and other facilities construction operations.

The characteristics of the electric wrench :(1) long service life (2) good heat dissipation of the handle and housing materials (3) high power (4) strong impact resistance (5) hands with the highest cost performance

Electric twist shear wrench is a kind of tool for high strength bolt of final tightening twist shear type. There are generally electric twist shear wrench and manual twist shear wrench, among which electric twist shear wrench is relatively common.

Application of twist shear wrench: the initial tightening of twist shear type high-strength bolts can use impact electric wrench or fixed torque wrench, and the final tightening must use twist shear wrench, so the twist shear wrench is specialized in the final tightening of twist shear type high-strength bolts.

The use of twist shear wrench: twist shear wrench is the end of the twist shear type high-strength bolts, its purpose is to turn the torsion shear type high-strength bolts can be broken. When working, aim the wrench head at the bolt head, and then pull the switch to start working. After a few seconds, the bolt plum head will be twisted off, and then pull out the wrench and pull the trigger to pop the plum head out, and the work will be finished.

The characteristics of twist shear wrench: easy to operate, saving time and effort, safe and convenient.
