What is the principle of the magnet chuck device used for lifting steel plates in the factory

The working principle is made using Faraday's principle of electromagnetic induction. The interior is made of high-performance permanent magnetic material neodymium borax, which can produce strong suction in the magnetic circuit, and change the magnetic field lines through the flipping of the handle to make the crane in a working or closed state; It does not need external power supply, and it is a new type of lifting tool that is both safe and energy-saving, and has high efficiency. That is, the use of electromagnet super magnetic penetration adsorption capacity, when the equipment is charged with magnetism, you can use remote control lifting, blanking only need to press the demagnetization button on the controller can be demagnetized, after demagnetization means that there is no magnetism, the steel plate will be put down.

To fill the magnetization, press the magnetization button, and the magnetization will be completed in 1-2 seconds. Electric permanent magnet lifter, this is the principle. <>

Electromagnet, energized and magnetic, demagnetized when de-energized.

The principle is magnet suction.

What are the electromagnetic chuck cranes? There are still a lot of electromagnetic chuck spreaders,**Or there are a lot of related electromagnetic chuck spreaders in Jingdong,I think you can go and take a look,Learn about it。

There are three types of steel plate magnet cranes. Pliers (hooks), vacuum suction cup spreaders, electric permanent magnet spreaders. It's different.

The pliers are simple and easy to use. However, the manual operation is intensive. There may be metal fatigue and decoupling.

The vacuum suction cup spreader is precise but cumbersome to operate. High requirements for the surface of the steel plate.

The electric permanent code digging magnetic spreader is easy to maintain, high efficiency and high safety factor. But the cost is relatively high.

No matter what type of spreader is used, you should pay attention to the precautions for steel plate hoisting:

1. The suspension and hanging operation shall be carried out by the qualified person of the suspension and hanging operation.

2. Choose tongs that match the use.

3. It should be used within the allowable load range of Chi Feng and should not be overloaded.

4. It is used within the scope of the allowable plate thickness fan scattered source.

5. Do not enter the hoisting operation range or the overturning area.

6. Do not knock or impact the hanging objects and spreaders.

7. Do not make the hanging object move sharply or stop sharply.

8. To avoid the heavy hanging objects, it is best to use more than 2 tongs for safety.

9. Before use, check the biting head, gasket, blockage between teeth, wear state and other abnormal phenomena, and then use it.

Electromagnetic lifting chucks are generally divided into ordinary electromagnetic lifting chucks and electric permanent magnet lifting chucks.

Electric permanent magnet lifting suckers. It has the characteristics of an electric permanent magnet. There is still magnetic force after the power is off.

Electromagnetic lifting suction cups.

Electromagnetic lifting suction cups. When the power is lost, the magnetic force is lost.

Common electromagnetic chucks include powerful magnetic chucks, multi-functional electromagnetic chucks and some ordinary rectangular magnetic chucks, which have different uses and different sizes of suction.

Lifting electromagnetic chucks, also known as lifting electromagnets and electromagnetic lifters, are mainly used for lifting magnetic materials such as steel in metallurgy, mining, machinery, transportation and other industries. It is also used as an electromagnetic manipulator to clamp magnetic materials such as steel, and is suitable for moving.

The main principle of automatic demagnetization: when magnetizing, the electromagnetic chuck starts to be magnetized from the initial zero state (i=0, b=0), with the increase of the excitation current, the magnetic induction intensity of the chuck increases along the initial magnetization curve, and when the excitation current increases to IM, the magnetic induction is strong.

The electromagnetic type is driven by the coil through the DC electric excitation magnetic suction, and the power is off to demagnetize and discharge. In order to prevent the material from falling in the event of a power failure, cranes with such suction cups generally need to have a backup power supply.

1. The magnetic effect of electric current (electricity will produce magnetism): Oster discovered that any wire that is connected with an electric current can produce a magnetic field around it, which is called the magnetic effect of electric current.

2. Non-magnetic metals can generate a magnetic field by passing an electric current, and its effect is the same as that established by a magnet.

3. There will be a magnetic field around the long straight wire with current flow, and the shape of the magnetic inductance line is a closed concentric circle with the wire as the center, and the direction of the magnetic field is perpendicular to the direction of the current.

Generally, the lifting electromagnetic chuck converts alternating current into direct current, and then enters the coil of the electromagnetic chuck, so that the electromagnetic chuck generates a strong magnetic field, so as to suck up steel objects.
