Electric Wrench
What Is Electric Wrench?
An electric wrench is a power tool that tightens and loosens bolts and nuts, and is a tool for tightening high-strength bolts. It is used for the initial screwing, final screwing and initial screwing of torsional shear high-strength bolts for the installation of large hexagonal head high-strength bolts for steel structure bridges, plant construction, chemical industry, and power generation equipment, as well as for occasions with strict requirements for the torque or axial force of bolt fasteners.
Advantages of Electric Wrench
Improve work efficiency
The speed of electric wrenches is much higher than that of manual screwdrivers and wrenches, which can greatly improve work efficiency. Its high-speed rotation is capable of completing many torsional operations in a short period of time. Especially in the case of frequent disassembly and installation of fasteners, the use of electric wrenches can save a lot of time and improve work efficiency.
Reduce work intensity
Using wrenches and screwdrivers by hand requires constant and hard turning, which can cause a lot of stress and fatigue on the wrists, shoulders and back over time. The use of an electric wrench is started by pressing the trigger, and the operation can be completed, which can reduce the labor intensity and fatigue of workers, and is safe and reliable.
Save time
The use of electric wrenches can greatly save the time of installation and disassembly, and is several times or even dozens of times faster than the manual use of wrenches and screwdrivers. For situations that require a large number of operations, the use of electric wrenches can quickly complete the task in a very short time.
Reduce labor costs
Since manual operation requires a lot of manpower, electric wrenches can greatly reduce labor costs, because it requires only a small number of personnel, can complete a large number of operational work, and reduces the cost of hired labor.

Application of Electric Wrench
Machinery manufacturing
Electric wrenches are widely used in the field of machinery manufacturing, mainly used for the assembly and maintenance of machines, and play an important role in machining. In the process of machinery manufacturing, many screws and nuts need to be tightened, if you use an ordinary wrench, it is not only laborious, but also difficult to control the strength when tightening, resulting in a lot of potential safety hazards. However, with an electric wrench, you can easily tighten or loosen various screws, which greatly improves work efficiency and reduces labor intensity.
Automobile maintenance
Electric wrenches are also widely used in the field of automobile maintenance, and their high torque and fast tightening ability make it easy to disassemble and assemble. In the maintenance process, some screws and nuts need to be tightened very tightly, and it is difficult to achieve precision and uniformity in manual operation, while the use of electric wrenches can complete the fastening and disassembly work with just one easy press, which improves the maintenance efficiency of the workshop and saves more time.
Aerospace
Electric wrenches are also an indispensable tool in the aerospace field, and are lightweight, compact and efficient, suitable for the maintenance and manufacturing of large machinery and equipment such as aircraft. In the aerospace field, due to the lightweight and tightness of the material, greater tightening force is required, and electric wrenches can not only ensure tightening strength, but also tighten tighter, making the equipment stronger and safer.
Construction projects
Electric wrenches also have important applications in construction projects. A large number of steel bars are required to be processed and connected in the project, and as we all know, the workload of steel bar assembly is large and the intensity is high, and workers need to carry out a lot of physical work, and it is also easy to fatigue in long-term work. Electric wrenches can easily accomplish these demanding jobs and reduce the labor intensity of workers by providing high-torque tightening and disassembly capabilities.
Components of Electric Wrench
Main structure
The main body of an electric wrench consists of a shell, a handle, a transmission mechanism, a power switch, etc. The shell is usually made of hard plastic or metal material, and the handle is mostly ergonomic for easy operation. The transmission mechanism consists of an electric motor and gears, which is the core part of an electric wrench.
Motor
The motor of the electric wrench generally adopts a brushless DC motor, which has the characteristics of high efficiency, high torque and low noise. The motor is controlled by a power switch, and the running speed and direction of the motor are adjusted according to the instructions of the control system.
Gear transmission system
The gear drive system is an important part of the electric wrench and is responsible for transferring the power provided by the motor to the wrench head. A series of gear combinations are usually used to achieve different output torques and speeds. The gear set is made of high-strength materials to ensure the reliability and life of the transmission.
Control system
The control system of an electric wrench is mainly composed of circuit boards, chips and sensors. By sensing the operation of the wrench, it is fed back to the control system in order to adjust the operation of the motor and the position of the transmission gear. The control system can also monitor and alarm the fault of the electric wrench to improve the safety of the equipment.
The materials of electric wrenches mainly include high-strength alloy steel, special steel, steel, alloy steel, titanium alloy, aluminum alloy, carbon steel, chromium-vanadium steel, chromium-molybdenum steel and stainless steel. Among them, high-strength alloy steel is used to produce impact blocks for high-end electric wrenches due to its high strength, high hardness, and wear resistance to provide excellent performance and durability. Specialty steels, while relatively inexpensive, may not be as good as high-strength alloy steels in terms of performance and durability. Steel and alloy steels are often used to improve the hardness and wear resistance of materials. Titanium alloys are lightweight, high-strength and corrosion-resistant, making them suitable for the manufacture of high-quality automotive and aircraft parts. Aluminum alloy material is lightweight and has good corrosion resistance, but the hardness and strength are not as good as steel materials. Carbon steel is made of high strength, but it is easy to rust and oxidize, and needs to be treated with anti-corrosion. Chromium-molybdenum steel and stainless steel are also commonly used materials for electric wrenches, the former has high strength, high hardness, high toughness and high wear resistance, and the latter is characterized by good corrosion resistance, but relatively low strength and hardness.
How to Maintain Electric Wrench
Clean
Regularly remove dust and oil from the electric wrench with a clean cloth or brush. Individual parts of the electric wrench can be cleaned with a cleaning solution and brush to ensure thorough cleaning.
Check the power cord
Inspect the power cord regularly to make sure it is intact and to avoid aging or wear and tear on the line.
Lubrication
Lubricate the bearings, gears, and other moving parts of your electric wrench regularly to ensure proper operation and long service life. Use a lubricant that is suitable for your electric wrench and avoid using an overly viscous lubricant.
Inspection and replacement of wear parts
Inspect and replace wearing parts such as hammers and cylinders.
Store properly
Store the electric wrench in a dry and ventilated place and minimize the vibration and impact of the machine.
Operation and maintenance
Operate in accordance with the requirements specified in the manual, and do not overload. Electric wrenches that are frequently used should be inspected and maintained regularly.
An impact wrench is equipped with an air or electric motor that exerts a sudden, intense rotational motion on the set nut, usually in short pulses (every five seconds or so). The continuous, short, intense explosive force that tries to turn the fastener will eventually cause some movement (loosening or tightening). In addition to adding more force to increase the torque of the impact wrench, the pressure also pushes the fastener forward. This process helps the impact wrench to do a better job on the fastener than you would do it manually.
How to Use a Electric Wrench Correctly
Install the battery or plug it in
Depending on the design of the electric wrench, install the battery correctly or connect to the power supply.
Loading and unloading screws
Choose the right wrench head and install it on the electric wrench, making sure the wrench head matches the screws or bolts to avoid damage.
Adjust the torque
Depending on the size, material, and object of the screw, adjust the torque setting of the electric wrench to ensure that it does not cause damage or is not securely installed.
Get started
Turn on the power switch of the electric wrench, align the wrench head with the screw, press the wrench button, the electric wrench will automatically provide enough torque to tighten the screw, and when the set torque value is reached, the electric wrench will automatically stop.
Precautions
When operating, the electric wrench should be kept perpendicular to the working surface to avoid generating additional torque, which may cause damage to the wrench head or screw, during use, do not touch the reaction arm to avoid injury, replace the carbon brush in time to prolong the life of the motor, and avoid repeatedly tightening the same screw.
Precautions for Using a Electric Wrench
Do use the right-sized bit
Always use the right-sized bit with an impact wrench. Impact wrenches support different bits. You can remove the existing bit and replace it with a new bit in a different shape or size. The bit, of course, needs to fit the fastener with which you intend to use the impact wrench.
Don't cross-thread
When using an impact wrench, try to avoid cross-threading. Cross-threading is a phenomenon that occurs when a male fastener "crosses" the threads of a female fastener. It's a common occurrence with impact wrenches because of their sheer power. If you happen to cross-thread a set of fasteners, you may struggle to separate them.
Do familiarize yourself with power source
You should familiarize yourself with the impact wrench's power source before using it. Most impact wrenches are powered by either compressed air or electricity. Also known as pneumatic impact wrenches, compressed air impact wrenches are the most common. Electric impact wrenches, however, are convenient because of their portable and easy-to-use design.
Don't overtighten
In addition to cross-threading, another mistake to avoid when using an impact wrench is overtightening. Assuming you're trying to install a fastener, you'll need to tighten it. Installing fasteners requires tightening, whereas removing fasteners requires loosening. But tightening a fastener too much may result in damage. You could end up breaking the fastener, or you could damage the surface in which it's inserted.
Do wear safety eyewear
Whether you're using a pneumatic or electric impact wrench, you should wear safety eyewear. Eye injuries are common in the workplace. The u.S. Centers for disease control and prevention (cdc) states that roughly 2,000 workers sustain an eye injury each day in the united states. With safety eyewear, you can lower your risk of sustaining an eye injury when using an impact wrench.
Don't use at an angle
Try to avoid using an impact wrench at an angle. The correct way to use an impact wrench is to place it directly over the faster so that it's perpendicular to it. This will give you the most torque while also lowering the risk of damage to the fastener and the surface.
Installation location
The electric wrench needs to be installed on a stable ground, close to the power socket, and easy to wiring.
Tool preparation
You need to use the tools required to install the electric wrench, including wrenches, screwdrivers, pliers, clips, etc.
Check the power supply
Before use, check whether the power supply meets the voltage requirements of the electric wrench and whether it is stable, so as not to cause equipment failure.
Remove the electric wrench
First remove the shell of the electric wrench, open the inside of the machine, and find the motor mounting plate.
Fix the motor
Fix the motor mounting plate on the static plate with screws, and pay attention to the bolts not to be fixed too tightly.
Connection between the motor and the reducer
Connect the motor with the reducer, and generally use the coupling for connection.
Fix the reducer
Fix the reducer on the base, and the fixing screws should not be too tight.
Connect the power supply
Turn on the power supply and test the electric wrench to ensure that there is no abnormality.
Operation specifications
It must be operated in accordance with the specifications for the use of electric wrenches, and comply with the relevant safety operation procedures to avoid equipment failure and potential safety hazards.
Maintenance
Electric wrenches need to be maintained frequently, including cleaning and lubrication inside the machine, as well as electric wrench accessories.
Environmental conditions
The electric wrench needs to be operated in a dry, ventilated and suitable temperature environment to avoid damage to the equipment by moisture and moisture.
