Permanent Magnetic Chuck 20150311
Neodymium Permanent Magnets Manufacturer China Rare Earth Magnet Limited
Permanent magnetic chucks are magnetic fixtures that are widely used in processing fields, like machinery factories and molding factories, which can greatly improve clamping efficiency of magnetic steel materials. Permanent magnet chuck use rare earth neodymium magnet materials as cores and can change magnetic system of neodymium magnets inside of the chuck, which can attract and release artifacts that are processed, through flipping handles of suckers.
In machining and mold manufacturing industries, clamping often used vices or pressing plates, which were time-consuming and inefficient. With appearance of high-performance neodymium magnetic materials, neodymium iron boron tends to be raw materials for developing magnetic fixtures. Therefore, permanent magnetic chucks emerge as required.
Application Theory
Based on principle of continuity of magnetic flux and principle of superposition of magnetic field, magnetic circuits of magnetic chucks are designed into several magnetic systems. Through relative motions of magnetic systems, strength of magnetic fields can added or canceled out, in which way attraction and releasing can be realized.
Features
1. With high-performance neodymium permanent magnets materials as cores, sizes become smaller, lifting capacities stronger and magnetism is perpetual.
2. It can be used without electricity, saving troubles of electricity supply.
3. Optimized magnetic circuits make residual magnetism low to zero.
4. Professional designs enable appearance of the products to be better-looking.
Related Design
Before a permanent magnetic chuck is designed, the magnetic circuits should be well designed. A nice magnetic circuit enables more magnetic flux to concentrate on working surface, which meet the requirement of lifting capacity. Meanwhile, it can reduce usage of neodymium magnets materials. There are two magnetic circuits in a permanent magnet circuit, which can be classified into two parts---one is flexible and the other is fixed. In order to reduce magnetic resistance and increase magnetic flux on key working surface, it will adopt some flexible magnetic materials as magnetic yokes in permanent magnetic circuits.
Maintenance
1. Before using the sucker, the surface should be cleaned in order not influence accuracy.
2. Working temperature should be -40°C to 50°C.
3. After being used, it should be rubbed with rust-resistant oil.
China Rare Earth Magnet Limited customizes many types of magnetic assembly including neodymium magnet / smco / alnico / ferrite & steel parts / plastic parts / rubber parts, etc.
