The principle of magnetic tool and assembly

Why you need a Magnetic Tool and Magnetic Assembly?

In industrial production and daily life, some tasks require a lot of effort, such as the need to lift a large billet or iron object. Most of the various parts and accessories are made of iron materials, and it is very laborious to carry them. There are also a lot of machined iron filings and nails from the renovation of the house, which are difficult to clean, or it is very troublesome to clean up. In work and life, we often encounter the need to place keys, umbrellas, tools, sticky notes and other items on the wall, cabinet, refrigerator or door. At this time, we hope to have an item that can easily meet our requirements.

Magnetic tools and magnetic assembly are born for this application. It converts one of the most magical forces in nature-the magnetic force of magnets into the power that we need, thereby replacing human physical power or power that cannot be achieved by electronic machinery. For example, a permanent magnet lifter can easily pick up 6 tons of steel, a magnetic sweeper can quickly clean up iron filings and nails on the ground of 100 square meters, and a magnetic pick uip arm can move hundreds of screws into your tool box at one time. A magnetic hook can easily hang up your keychain, umbrella, bag, etc.

It can also be used in special environments, such as high temperature environments. Generally, magnetic tools which assembling neodymium iron boron magnets can work in environments below 80 degrees Celsius. If there is a higher temperature resistance requirement, above 200 degrees Celsius, ferrite magnets can be used if the required magnetic force is not high. , Use AlNiCo magnets where the magnetic force is required higher.

Overview of Magnetic Tools and Magnetic Assemblies

Magnetic tools are made into various tools that meet different needs by using the magnetism of magnets and the permeability of metal iron parts. Including magnetic sweepers, magnetic picker up tools, permanent magnetic lifters, magnetic tool holders (disks), magnetic holding devices, magnetic daily-use kits, magnetic fuel-saving devices, magnetic water softeners, permanent magnetic chucks, etc.

Magnetically conductive materials: pure iron, low carbon steel, iron-aluminum, iron-silicon, iron-nickel, iron-cobalt alloy, ferrite, nickel, cobalt, etc. Generally speaking, the permeability of alloys is higher than that of pure metals. Generally, permalloy is used in places with higher requirements, that is, nickel-iron alloy with a nickel content of 30% to 90%, which has good workability and high magnetic permeability.

Schematic diagram of metal permeability of magnetic field

As shown in the figure, metal iron or carbon steel can change the direction of the magnetic field of the magnet, and the magnetic force will extend along the shape of the metal plate. This is the most basic principle of magnetic tools and magnetic components. The magnetic force of the magnet can be changed according to different needs. Metal and iron are combined into various shapes and structures to meet application requirements. Because metal iron and carbon steel are everyday materials with good quality and low price, they are also materials with very good magnetic permeability, so they are the most common in magnetic tools and components.

Lifting magnets:
Magnetic lifters are the tools designed to lift heavy metal objects such as steel plates, iron logs, rods, and bundles of chains, slings, and blocks, etc., with the help of permanent magnets' magnetic strength. It is pretty useful as it reduces the man load and makes it easy to lift cumbersome objects that are otherwise difficult to move. The use of permanent magnets eliminates the requirement of electric power as well. These can be in different forms and ranges depending upon their capability to withstand a specific weight. We manufacture a range of high-quality, user-friendly, and cost-effective magnetic lifters to help our customers in their work.

Lifting magnets characteristics:
Our lifting magnets are of high-quality neodymium magnets having a strong capacity to attract and lift heavy metal objects. The lack of any power supply requirement makes its use safer for the handler. Our main customers belong to the factories and construction areas where metal blocks, sheets, machine pieces, metal wire rolls are lifted to heights. Following general characteristics of lifting magnets make them suitable for load lifting:
• Rare-earth neodymium magnets are used
• It can be operated easily by one man.
• More efficient as compare to traditional object lifting ways.
• Its base is flat, which performs the best attachment.
• The permanent magnet enables it to withstand the heavyweights, i.e., from few Kgs to several Tons.

• It contains a clamp, release round, and maneuver.
• An additional power supply is not required.
• It is safer than electromagnetic lifters.
• Its lever is self-locking which prevents any accidental deactivation.

Basic components of a magnetic lifter:
There are two basic parts of a lifting magnet device, i.e., the sucker and a discharger. The bottom part comprises of sucker, which is made of a permanent magnet and a conductive plate. While the upper portion contains a lever that can on and off the device. When the lever is at its on position, magnet poles' magnetic flux is transferred to the conductive plate via a wire. The charged conductive plate gets attached to the object and completed the circuit.
Working of magnetic lifter:
A magnet lifter contains two poles of the best-grade magnet at their bottom surface. The production of strong magnetic flux between these two poles performs a key role. To lift any metal object, a magnetic lifter is placed on the surface of the object to be lifted; the handle is turned on to enhance the magnetic flux finally lift the attached object. Once the heavy object is placed at the required place, the handle is turned off, and the object set free from the lifter.
Certain considerations:
We highly appreciate our customers sharing their applications with us to choose the best suitable device for their work. We understand that there are sometimes security issues due to which customers cannot give us the complete detail. For this, we recommend our customers consider the following important points to make an appropriate choice for the best suitable metal lifter:
• The grade of permanent magnet required.
• A per-day estimated use of the magnetic lifter should also be considered.
• The estimated weight of the metal objects to b lifted.
• The working space's temperature should be kept in mind because neodymium magnets cannot work at extremely high temperatures.
