Product Description

Electric wrench refers to an electric tool used to tighten and loosen bolts and nuts, and is a tool for tightening high-strength bolts. Used for the initial and final tightening of high-strength bolts with large hexagonal heads in the installation of steel structure bridges, factory buildings, chemical and power generation equipment, as well as the initial tightening of high-strength bolts with torsion shear type, and in situations where there are strict requirements for the torque or axial force of bolt fasteners.
Structure:
Electric wrenches have two structural types: safety clutch type and impact type.
The safety clutch type is a structural type that uses a safety clutch mechanism that releases when a certain torque is reached to complete the installation and removal of threaded parts; Impact type is a structural form that uses an impact mechanism to complete the installation and removal of threaded parts with its impact torque. The former, due to its simple structure, small output torque, and certain reaction torque, is generally only suitable for manufacturing electric wrenches of M8mm and below; The latter has a complex structure and high manufacturing process requirements, but its output torque is large and the reaction torque is very small, making it generally suitable for manufacturing larger specifications of electric wrenches.
The impact electric wrench consists of an electric motor, a planetary gear reducer, a ball screw groove impact mechanism, a forward and reverse power switch, a power connection device, and a motorized sleeve.
There are single-phase series excited electric wrenches and three-phase electric wrenches according to the type of electric motor selected.
