How does a permanent - magnet lifter work?

ght that magnets are very magical, and we would rummage through everything to find two magnets to play with. Magnets are widely used in our daily life. They can be found everywhere in transportation tools and electrical appliances. Among magnets, there is a kind of the strongest magnet called neodymium - iron - boron magnet. It can attract objects hundreds of times its own weight, which shows its great power.

In various lifting machines, electricity is required to make the machines work. However, there is a kind of lifting equipment that no longer needs electricity after using magnets. This is the permanent - magnet lifter. The permanent - magnet lifter is a kind of lifting equipment that lifts objects by magnetic force without using electricity. It has many names, such as magnetic lifter and lifting magnet. It has the characteristics of small volume, strong lifting capacity, no need for electricity or other energy sources to drive, and high safety. It is suitable for handling steel plates, iron blocks and cylindrical steel materials, such as mechanical parts, punch dies, and various steel materials.

The permanent - magnet lifter uses high - performance neodymium - iron - boron as the material to generate a strong suction force in the magnetic circuit. Once the neodymium - iron - boron magnet is magnetized, it can maintain a constant magnetism and is not easy to be demagnetized. Using this kind of magnet can ensure that the lifter has a continuous and stable magnetism.

The structure of the permanent - magnet lifter is relatively simple. The control handle rotates left and right to control the magnetic core to lift and lower the lifted workpiece. The magnetic core is composed of multiple neodymium - iron - boron magnet blocks and is the core component of the entire lifter. The lifting ring is the component that connects the lifter. The bottom V - shaped groove is designed to have a larger contact area and prevent the cylindrical object from rolling left and right when sucking some cylindrical objects. The shell is used to protect the internal parts and assemble the entire product.

When the permanent - magnet lifter needs to be in the working state, rotate the handle 180 °, and the magnetic pole direction of the entire magnetic core will change to form a magnetic closed loop, so that the workpiece can be firmly sucked on the working surface of the permanent - magnet lifter.

Now, the permanent - magnet lifter has become an important direction of technological development and is widely used in many fields. With its existence, the work efficiency and safety have been greatly improved.
