Multi-pole-set integrated through-type demagnetizing device

Abstract

The invention relates to a multi-pole-set integrated through-type demagnetizing device which comprises belt conveyors, multiple demagnetizing assemblies and a supporting plate used for supporting the demagnetizing assemblies; the supporting plate is fixedly arranged under a conveyor belt of the belt conveyors, and the demagnetizing assemblies are arranged in the conveying direction of the conveyor belt; each demagnetizing assembly comprises a shell with an opening in the upper end, a cover plate capable of closing the shell, an iron core set arranged in the shell and coil windings matched with the iron core set, each iron core set is composed of a bottom magnetic disc and multiple iron core limbs arranged on the bottom magnetic disc, each iron core limb is sleeved with one coil winding, and all the coil windings are connected to a demagnetizing circuit. According to the through-type demagnetizing device, the structure is simple, a magnetic field is generated only through the combination of the iron core sets and the coil windings, and the fault rate of the device is low in the operation process; in addition, workpieces can smoothly and steadily pass through a magnetic field area in the demagnetizing process, parts are prevented from being scratched, chamfers are prevented from being damaged, and therefore the rejection rate of the demagnetized workpieces is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of demagnetization treatment devices, in particular to a multi-magnetic pole group integrated through-type demagnetization device. Background technique [0002] In industrial production, many workpieces are processed by using electromagnetic chucks to absorb workpieces. After processing, the magnetism needs to be eliminated to ensure the processing accuracy and inspection quality of the products. However, for the demagnetization of mass-produced workpieces with multiple varieties, different shapes, and large size differences, a demagnetization device with strong compatibility with workpiece sizes and suitable for multiple varieties and specifications is needed to achieve the purpose of demagnetizing batch workpieces. [0003] At present, the demagnetization device that can satisfy the above-mentioned situation usually adopts a permanent magnet demagnetization machine. this kind [0004] The characteristic ...

Problems solved by technology

[0005] This demagnetization method has certain requirements on the size and height of the workpiece. It is necessary to adjust the up and down moving screw of the demagnetization device according to different heights of the workpiece, so that it can choose an appropriate height as much as possible to achieve the demagnetization effect. For many companies, there are multiple varieties every day. When the workpiece needs to be demagnetized, it is necessary to repeatedly adjust the height of which group of demagnetization devices above, and the operation is more cumbersome

This demagnetization method has a problem that is unavoidable. During demagnetization work, when a batch of workpieces passes through the permanent magnet demagnetization device with the conveyor belt, which group of permanent demagnetization devices above will appear to absorb the workpiece through the workpiece, and the workpiece will be adsorbed on it. A set of permanent magnets on the shell of the demagnetization device, detached from the conveyor belt

Under the rotation transformation of the rotating NS pole, the workpiece is constantly vibrating on the shell of the demagnetization device. Under the vibrating workpiece, the conveyor belt is constantly carrying batches of demagnetized workpieces through, and some workpieces will be subjected to the upper , Under the impact of shaking the workpiece, the workpiece will be scratched, and the chamfer will be bumped.
