The reason why the electric wrench is not working
Electric wrench features: (1) long service life (2), handle and shell material, good heat dissipation (3), power (4), impact resistance (5), hand use, the highest cost performanceElectric torque shear wrench is a kind of tool for high strength bolt with end tightening, torsion and shearing. There are electric shear wrench and manual wrench in this paper, among which electric wrench is more common.Torsional shear wrench application: torsional shear type of high-strength bolts of the initial tightening, the use of impact electric wrench or fixed torque wrench, and the final tightening must use the torque shear wrench, so the torque shear wrench is a special end, tight, twist, scissors type high-strength bolts.The use of torsional shear wrench: torsional shear wrench, mainly end, tight, twist, scissors type high-strength bolts, its purpose is to twist scissors type high-strength bolts plum head can interrupt. When will the wrench head alignment bolt head, pulled a switch to start work, after a few seconds, bolts plum head will be broken, and then pulled the trigger head wrench plum pops up, that is the end of work.Torsional shear wrench features: easy to operate, time-saving and labor-saving, safe and convenient.
The power wrench may be due to: 1, motor damage; 2: the battery is dead.
Electric wrench is mainly used in the steel structure installation industry, specially installed steel structure high-strength bolt, high strength bolt is used to connect the steel structure contact, usually with bolt group way. High strength bolts can be divided into torshear type and the big six angle two GB, torshear type high strength bolt for M16, M20, M22, M24 four, M27, M30 non GB two GB; six angle high strength bolt for several M16, M20, M22, M24, M27, M30 etc.. General for high strength bolts fastening must first end tight and tight, and each need to have strict requirements of torque. Large six angle high-strength bolts of initial tightening and final tightening must use fixed torque wrenches. Therefore, all kinds of electric wrenches are needed for fastening.
Impact electric wrench is mainly the initial bolt, and its use is very simple, that is, pointing bolt, pull the power switch on the line. The electric torque shear wrench is mainly end tightening, torsion scissors type high-strength bolt, and its use is to bolt the power switch, until the twist scissors type high-strength bolt plum head interrupted. The electric fixed torque wrench can be both tight and tight at first. Its use is to adjust the torque first, then tighten the bolt. The electric angle wrench is also a kind of fixed torque wrench. Its use is to adjust the degree of rotation first, and then tighten the bolts. The electric angle wrench is an electric spanner specially used for fastening the angle bolt of the steel frame, and the electric wrench is the same as the electric wrench.
Electric torque shear wrench, as its name suggests, is the necessary tool for twisting, cutting, plum head bolts tightening operations, to help you install, dismantle bolts, nuts, and more accurately control the tightening torque. By using the bolt to fix the torque, the plum blossom head part of the bolt can be sheared when the wrench reaches a certain torque, and the torque precision and the axial pulling force are ensured by the fixed torque V notch of the bolt. Disassembly torque is larger, more reliable than manual. The utility model is convenient, beautiful, practical and easy to carry with the car. Widely used in steel structures, bridges, factories, power generation equipment and other facilities construction work.
