Basic concepts
Wind bit, scientific name pneumatic screwdriver bit, is a pneumatic tool bit used to tighten or loosen fasteners such as screws, screws, nuts, etc., applied to pneumatic screwdrivers, and the power source is treated compressed air.
Working principle
The air biter compresses the air through the air compressor, uses the air pressure to drive the blades in the motor in the air batch, the blades drive the rotor, and then the rotor drives the screwdriver, and the screwdriver drives the screw to rotate, so as to realize the loosening or tightening of the screw and the nut. When the bolt reaches the specified torque value, the torque compression spring and other devices inside the wind batch make it disconnected from the transmission device to achieve the ability to achieve a fixed torque.
peculiarity
Strong power:
The air bit is powered by compressed air, which can provide large torque output, and can easily tighten or loosen screws of various specifications, which is suitable for working scenarios with high torque requirements, such as automobile maintenance, mechanical assembly, etc.
Faster rotational speed:
The rotational speed of the air batch is usually 1000-2800 revolutions per minute, which is faster than the electric batch, which can improve the work efficiency, especially in batch operations.
Long service life:
The high-pressure gas of the air batch can take away part of the heat, unlike the friction between the coil and the motor of the electric batch, which is easy to generate a lot of heat, and is relatively less prone to heat, thus prolonging the service life of the air batch head.
Precautions for use
Air source treatment:
When using the air bit, it is necessary to receive air through the air compressor, and the compressed air must be properly treated to ensure that it is clean, dry, free of moisture and dirt, so as to ensure the normal operation and service life of the tool, and prevent impurities from entering the inside of the air biter to cause wear or failure.
Correct operation:
When operating the air bit, keep the air bit perpendicular to the workpiece, and avoid tilting force, so as not to damage the bit and the workpiece. At the same time, according to the specifications and materials of the screws, select the appropriate bit type, and adjust the torque value of the air batch to ensure that the tightening force is moderate.
Regular maintenance:
Regularly clean, lubricate and maintain the air bits, check whether the bits are worn, deformed or damaged, and replace them in time if there are problems to ensure the performance and safety of the air bits.
FAQ
Q: The fit between the wind bit and the screw is poor, what should be checked?
A: The bit head is worn, the screw notch is deformed, or the output torque of the air screwdriver is unstable.
Q: After installation, the air bit head rotates and there is a lag, where is the common problem?
A:There are burrs on the shank, the air batch sleeve is worn, or the bit bit does not match the size of the sleeve
Q: How to deal with the weakening of bit magnetism after long-term use?
A: It can be re-magnetized, if there is no improvement after magnetization, the bit with the core needs to be replaced.
