Also known as a ratchet wrench and power tool assembly, it mainly provides tools with high torque output and minimal consumption.
Compressed air is the most common power source, although electric or hydraulic power is also used, and battery units have grown in popularity in recent years.
Pneumatic wrenches are used in many industries such as auto or motorcycle repair (almost every auto repair shop or motorcycle specialty torque output), major construction projects, and anywhere else where high torque output is required.
Available in every standard ratchet socket drive size, from small 1/4' drive tools for small assembly and disassembly, to 3.5'.
Among many electric tools, pneumatic impact wrench is a tool that provides high torque output with minimum consumption, and is widely used in many fields, such as municipal construction, metallurgy, building assembly/manufacturing, railway shipbuilding, automobile, chemical industry, etc. .So, what is the principle of pneumatic impact wrench?Next, let's get to know it together.To put it simply, the principle of the pneumatic impact wrench is to drive the air motor mechanism to rotate through high-pressure gas (generally 6.2Kgf), and then output it to the striking mechanism through the rotor, and the striking mechanism drives the striking shaft to form a reciprocating back and forth and rotational movement.
For a detailed explanation, one or two powerful air motors can drive a torque multiplier with three or more epicyclic gears, and the torque can be controlled by adjusting the gas pressure. To allow specific torque requirements, each The tools are equipped with dedicated air pressure vs. torque charts and calibration reports.And for further application, the pneumatic torque wrench can be equipped with a torque sensor at the same time, and the output torque is more accurate.After obtaining the required torque, the air supply can be closed manually or automatically by using a suitable circuit system.
Let's add some other relevant knowledge.Among them, in the classification of pneumatic wrenches, in addition to pneumatic impact wrenches, there is also a pneumatic torque wrench. The difference between the two is that the pneumatic torque wrench can adjust the torque, while the pneumatic impact wrench cannot.Moreover, the accuracy of the general pneumatic torque wrench can reach within 5%, the adjustable torque range is large, and now the maximum torque can reach 12,000 Nm; while the pneumatic wrench is mainly an impact wrench, which has torque but the torque is usually small, and the torque is not accurate Yes, it is noisy.Compared with the two, the price of pneumatic torque wrench is high, which is generally imported, and the price of pneumatic wrench is low.
Also, the most common source of power for pneumatic impact wrenches is compressed air.In addition, there are also electric or hydraulic ones, and in recent years, the use of batteries has also become popular.Also, pneumatic impact wrenches are available in every standard ratchet socket drive size, from small 1/4 drive tools for small assembly and disassembly, to 3.5.However, pneumatic impact wrenches are generally not suitable for the fastening of ceramic and plastic mounting parts.
The maintenance of the pneumatic impact wrench is also very important.First of all, you need to have a correct air supply system, which is the premise to ensure that the tool can be used longer and better.Secondly, do not easily remove the parts in the tool to avoid tool damage and possible safety accidents.In addition, you must be diligent in inspection. If you find that the tool is faulty, you must repair it as soon as possible before using it, and you must also be diligent in adding lubricating oil for maintenance.
