The components and working principle of the pneumatic scissors tool

- Sep 19, 2019-

The pneumatic scissors tool requires the following parts to operate normally: power output part - operation form conversion part - intake and exhaust part part - movement opening and stopping control part - energy supply part - air filtration and air pressure adjustment part

Power output part:

It is one of the main components of pneumatic tools. It mainly consists of a pneumatic motor and a power output gear. It relies on high-pressure compressed air to blow the motor blades to rotate the motor rotor, externally output rotary motion, and transform the entire operation form through gears. Part of the movement. No matter what kind of air motor, it relies on compressed air to blow the motor blades to drive the rotor to rotate. When the motor blades rotate at high speed, they always rub against the inner wall of the stator. It is the most common vulnerable part in the motor, so it High requirements on the quality of compressed air and the presence of lubricating oil in compressed air;

Job form conversion section:

It mainly converts the rotational motion of the motor output accordingly. For different types of pneumatic scissors tools, the operating part conversion part is mainly divided into mechanical clutch and planetary gear set, friction plate clutch and planetary gear set, hydraulic cylinder, torsion bar and hammer block group.

Intake and exhaust section:

Obviously, the intake and exhaust section is the relevant passage for the ingress and egress of compressed air, and is an energy supply system that ensures the normal movement of the motor;

Motion on and off control section:

That is to say, the pneumatic switch (magnetic valve) generally described is susceptible to damage because it is in direct contact with the operator and external objects at the moment, and is multi-engineered plastic products;

Energy supply part:

The compressed air is mainly formed by the air compressor compressing the atmosphere, and is transported by the compressed air pipeline to the relevant gas and electricity, and is pulsating.

Air filtration and air pressure adjustment section:

Since compressed air is usually transported through pipes made of seamless steel pipes, rust on the inner walls, moisture in compressed air, dust, etc., will continue to form during long-term use. If such compressed air does not undergo any treatment and directly enters the air motor, the life of the motor will be greatly shortened, resulting in insufficient power output of the whole tool and instability, which may cause damage to the connecting parts of the motor and the like. Compressed air filtration and adjustment devices must be provided between the compressed air delivered by the pipeline and the pneumatic tools. The pneumatic triple joints undertake this task. The pneumatic triple joint is mainly composed of a barometer, a filter, an oil mister, a pressure regulator and the like.
