What Is a Pneumatic Tool?

In a broad sense, pneumatic tools are mainly a tool that uses compressed air to drive an air motor to output kinetic energy. According to its basic working methods, it can be divided into: 1) rotary type (eccentric movable blade type). 2) reciprocating type (Volume piston type) General pneumatic tools are mainly composed of power output part, operation form conversion part, intake and exhaust path part, operation start and stop control part, tool housing and other main parts. Of course, the operation of pneumatic tools must also have an energy supply part, Air filtration and air pressure adjustment parts and tool accessories.

Air source

Safety first, use second

Some pneumatic tools may generate reaction force torque during use, which makes the operator's body in a state of tension, affects the balance of the body, and may pinch fingers. Therefore, especially when using multi-axis nut locking equipment,

The air is easy to obtain and the working pressure is low. The used air can be discharged on-site without the need to recover the pipeline. The gas has small viscosity and small flow resistance loss, which is convenient for centralized air supply and long-distance transportation.

Confucius said, "If you want to be good at work, you must first sharpen it." To complete each processing or assembly task, you must first equip with appropriate and excellent tools. Hardware tools can not only be used without maintenance, that will reduce the service life of hardware tools. Let's talk about the use and maintenance of pneumatic screwdrivers in pneumatic tools. Pneumatic tools are mainly used in tightening and assembly. Automotive manufacturing, electronics, home appliances, auto parts production, equipment maintenance, and aerospace are the main industries for its application. Precision, reliability and durability are the functional criteria of pneumatic tools. The quality of rotary pneumatic tools depends on six aspects: the performance of the built-in pneumatic motor (rotating power); the metal materials and processing methods used for the parts of the transmission mechanism; the machining accuracy of the parts and the accuracy of the tool assembly; tools Design, production innovation, optimization, improvement; quality control; correct and reasonable use.

1. The correct generation air supply system: the inlet pressure at the tool inlet (non-air compressor outlet pressure) is generally 90PSIG (6.2Kg / cm ^ 2), too high and too low will damage the performance and life of the tool . The air intake must contain sufficient lubricating oil, so that the air motor in the tool can be fully lubricated. The air intake must be free of moisture, and it is not appropriate if the contracted air is not air-dried. 2. Do not arbitrarily remove the parts of the tool and operate it, except that it will affect the safety of the operator and cause damage to the tool. If the tool is slightly faulty or cannot reach the original function after use, it can no longer be used, and it should be checked immediately. 4. Regularly (about once a week) inspect and maintain tools, add grease to rotating parts such as bearings, and add oil to the air motor. 5. When using various tools, be sure to follow various safety regulations and instructions for use. 6. It is necessary to use appropriate tools for work. Too large a tool is likely to cause work injury, and too small a tool is likely to cause tool damage.

The future of air tools

1. In terms of operating capacity, pneumatic tools can be easily operated through the operation of the supply valve handle and adjusting the regulating valve. It can provide more levels of choice in the speed range. Under the same output power, it is comparable to electric tools. Compared with small and lightweight, pneumatic tools are more suitable for long-term work without heat generation. Even if the compressed air engine is overloaded, the starting tool just stops rotating, and once the overload occurs, the normal operation resumes. Second, in terms of economic performance, the initial investment of electric tools is small, but long-term energy consumption is high, and the cost of tool repair and replacement is also high. The initial investment of pneumatic tools requires the establishment of air pressure piping equipment, but long-term use has lower cost in energy consumption and tool maintenance. Third, in terms of environmental application capabilities, pneumatic tools are more resistant to water. Although water immersion is harmful to the tool, it will not cause electric sparks like hardware power tools to cause harm. And because the pneumatic tool can use the internal combustion engine air pump, it can adapt to various bad or harsh environments.

The "2013-2017 China Pneumatic Tools Industry Market Analysis and Development Trend Consulting Report" pointed out: Although the research and application of China's pneumatic manufacturing industry and pneumatic technology started relatively late, there have been great developments in the past ten years. The tool has the characteristics of high quality, long life, high speed, high output force and high precision. More and more businesses are optimistic about the pneumatic tool market. With the continuous progress of technology, the development of pneumatic tools will continue width! In China, manual tools are used for manual work in daily applications. They mainly include wrenches, screwdrivers, vise, etc. Under normal circumstances, a lot of power is not required. Manual tools are usually chosen, which is easy to operate and does not consume energy. . However, in the case of high power work, pneumatic tools have unmatched advantages of manual tools. Their high quality, long life, high speed, high output force and high precision are quickly promoted and applied to the assembly industry and machinery industry. , Power transmission industry, scooters, electric bicycles, motorcycle assembly, auto repair shops and some assembly line enterprises or manufacturers, play a significant role. In the future, pneumatic tools will develop in the direction of small-scale integration, precision intelligence, high speed, sterilization and energy saving. There are three main advantages: First, at the same output power, compared with electric tools, they are small and lightweight. The tool is more suitable for long-term work without heat generation. Even if the engine is overloaded, it can resume normal operation after the phenomenon is eliminated: Secondly, the pneumatic tool has better water resistance. Because the pneumatic tool can use the internal combustion engine air pump, it can adapt to various defects Or harsh environment; finally, the initial investment of pneumatic tools requires the establishment of air pressure piping equipment, but the long-term use has lower cost in energy consumption and tool maintenance.
