Embodiment Construction

[0010] The conveyor belt 6 rotates circularly under the drive of the transmission motor 11 , the transmission chain 10 and the transmission shaft 3 . The number of revolutions is adjusted to 2m / min through the frequency converter 14, and the power of the demagnetization coil is adjusted to 65kw through the universal steering controller 13. The model of the frequency converter 14 is E2-201-H1, and the model of the universal steering controller 13 is LW5D-16YH3 / 3 , the outer diameter of the demagnetized workpiece is Φ150mm, driven by the conveyor belt 6, it passes through the fully enclosed hollow demagnetization coil 5 and the fully enclosed gantry demagnetization coil 8 at a constant speed to complete the demagnetization process.

[0011] According to actual needs, the working height of the demagnetization machine can be adjusted through the adjustable hoof 1, and the tightness or deviation of the conveyor belt 6 can be adjusted through the conveyor belt tensioning device 9 or ...

Abstract

Demagnetization machine includes housing, conveyer system, electrical control system and demagnetization system. The demagnetization system is composed on air core coil and portal shaped coil arranged in front and behind. Universal steering controller and frequency converter for conveyer belt is installed on the housing. Adjustable ungula is in base of the housing. Fine setting device and tensioning device for conveyer belt is installed on upper part of the belt. Conveyer belt is rotated circlewise, frequency converter adjusts number of speeds, universal steering controller determines power of demagnetization coil. Work pieces to be demagnetized on conveyer belt pass through fully enclosed air core coil and portal shaped coil in uniform velocity so as to complete de-magnetizing procedure. Features are: easy of operation, good effect of demagnetization, applicable to workpieces in different specifications and different heights.

Description

technical field [0001] The invention relates to a device for demagnetizing workpieces and its use method, in particular to a bearing rolling element demagnetization machine and its use method Background technique [0002] At present, with the increasing development of the national economy, a large number of bearings are applied to industries such as industry and transportation, and the production volume of bearings is also increasing year by year. After metal processing, a certain amount of magnetic content is formed. The magnetic content of the workpiece is also different, which greatly affects the quality of the workpiece. The demagnetization work efficiency and demagnetization standards required in the manufacturing process and the regular maintenance process after use are getting higher and higher. Relying on simple equipment for demagnetization can neither improve work efficiency nor ensure demagnetization quality, nor can it adapt to the rapidly developing world. need...
