Pneumatic screwdriver

Pneumatic screwdrivers are also called: Pneumatic screwdrivers, air batches, pneumatic screwdrivers, pneumatic screwdrivers, and so on. They are pneumatic tools used to tighten and loosen screws and nuts.

Pneumatic screwdrivers are powered by compressed air. Some devices equipped with adjusting and limiting torque are called fully automatic adjustable torque type. Abbreviations (automatic pneumatic screwdrivers) and some without the above adjustment device, just use the switch knob to adjust the amount of air intake to control the speed or torque. Semi-automatic non-adjustable torque type. Abbreviation (semi-automatic pneumatic screwdriver). Mainly used for various assembly operations. There are several parts of pneumatic motors, hammering devices or deceleration devices. Due to its high speed, high efficiency, and low temperature rise, it has become an indispensable tool in the assembly industry. Sources of products are divided into domestic and imported channels. There are semi-automatic hammering type, automatic torque control type. The operation start mode includes pressing mode and hand pressing mode.

one. Semi-Automatic Pneumatic Driver 1. A screwdriver that does not brake automatically after the torque is set. It is called a semi-automatic pneumatic driver. Usually semi-automatic design is hand-type and internal hammers are used for screw locking.

2. Semi-automatic ramming type pneumatic screwdrivers are usually simple in structure and durable, but they have no torque control. They are usually used in large screws and places where the locking torque is not strict, such as motorcycles, automobiles, ships, steel structures, etc.

two. Automatic pneumatic screwdriver 1. A pneumatic screwdriver that can fully brake and stop running after reaching the set torque is called a fully automatic air screwdriver.

2. The structure of fully automatic pneumatic screwdriver is relatively complex, including motor, clutch, deceleration, closed air brake and other devices. Usually used in small screws and tighten torque requirements such as: electronic appliances, home appliances and so on.

three. Hand Press Pneumatic screwdriver Operation The start mode requires the use of a finger to press the start lever, or the platen button.

four. The push-down electric screwdriver operation start mode eliminates the need to hold down the trigger lever or the pressure plate button with your fingers. Directly align the workpiece to start it.

Fives. The composition of the pneumatic screwdriver drives the screwdriver by compressing the air. It is widely used in the manufacturing industry. Pneumatic screwdriver shell is mostly made of metal material, and the hand feels slightly worse than electric, but the anti-static property of the metal shell is better.

Rotating speed:

The rotation speed is generally about 1000-2800r/min, because the motor is driven by high-pressure gas, so long-time high-frequency operation will not be hot.

Torque accuracy:

The use of mechanical braking, and the pressure of the air source will affect the torque stability of the screwdriver, so the error is generally about 5% to 3%. (If you add air conditioner, it will be better)

Energy consumption:

The use of compressed gas as a source of movement as long as the air line is reasonable for each driver's air consumption is about 0.28m2/min, relatively more energy-saving and environmental protection.

Maintenance costs:

Less consumables, as long as the usual pay attention to maintenance and fuel, generally within a year only need to change leaves,.

advantage:

Mainly due to high working speed, high safety, anti-static, low failure rate, long life, energy saving and environmental protection;

Disadvantages:

Feeling is not good, the accuracy of the torque reference to the stability of air pressure, single higher prices.
