? Nowadays, there are many kinds of tools and tools on the market. Electric wrenches are a kind of tools with high frequency of use, mainly impact wrenches, corner wrenches and angle wrenches, etc., which are mainly used in engineering construction and home decoration. As the most common tool, the electric wrench has a good appearance, easy to carry, convenient and practical. Next, we will introduce the application scope and performance of the electric wrench. Scope of application 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; the national standard large hexagonal high-strength bolts are M16 and M20. , M22, M24, M27, M30, etc. Generally, the tightening of high-strength bolts must 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, so various electric wrenches come for various tightening needs. Effect 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. Electric constant 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. Practical performance Electric torsional shear wrench, as the name implies, is an essential tool for torsion shearing torx head bolts. It helps you install and remove bolts and nuts, and can control the tightening torque more accurately. Using the fixed torque of the bolt, when the wrench reaches a certain torque, the torx head portion of the bolt can be cut. The torque accuracy and axial tensile force are guaranteed by the V-cut of the fixed torque of the bolt. The disassembly and assembly torque is large, which is more safe and reliable than manual.
