Introduction and use of torque wrench
source:Industry News release time:2021-03-25 Article author:Rosit Popular:Air band saw
Torque wrenches, also called torque wrenches and torque adjustable wrenches, are one type of wrenches. According to the power source, it can be divided into: electric torque wrench, pneumatic torque wrench, hydraulic torque wrench and manual torque wrench; manual torque wrench can be divided into: preset type, fixed value type, dial type, digital display type, slip type, bending Style, and kilogram wrench. When the tightness of screws and bolts is critical, the use of a torque wrench allows the operator to apply a specific torque value.
Introduction to torque wrenches
The main feature of the torque wrench is that the torque can be set and the torque is adjustable.
Pressure Wrench HKB Series-Hollow Type Product Features:
Using aluminum-titanium alloy material, one-piece molding, high toughness and light weight
The hollow hydraulic wrench is composed of a power head and a working head. It can be used for multiple purposes in one machine. One power head can be equipped with multiple working heads, and the working range is wide.
The tubing joint that can rotate 360°×180° is closer to the design of no tubing to avoid twisting and cracking of tubing
Extendable metric and imperial hexagon drive shaft and sleeve for working head
Suitable for use in small spaces
The torque repeatability is as high as ±3%, and it is equipped with a movable handle for easy movement
The refueling hole is beneficial to the life of the wrench, prevents wear and enhances lubrication
It can realize automatic and continuous disassembly and locking according to user needs, increasing the locking efficiency of conventional hydraulic wrenches by 1/3
Application of torque wrench:
Torque wrenches are used to tighten bolts. High-strength bolts can be divided into torsion shear type and large hexagonal type. National standard torsion shear type high-strength bolts are M16, M20, M22, M24. Now there are also non-national standard M27 and M30. ; National standard large hexagon high-strength bolts are M16, M20, M22, M24, M27, M30, etc. Generally, the tightening of high-strength bolts must be tightened first and then finally tightened, and each step requires strict torque requirements. A fixed torque wrench must be used for the initial tightening and final tightening of large hexagonal high-strength bolts.
Use of torque wrench
The torque wrench can be used for both initial tightening and final tightening. It is used to adjust the torque first, and then tighten the bolts.
Features of fixed torque electric wrench:
Convenient operation, time-saving and labor-saving, adjustable torque.
