Embodiment Construction

[0011] 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.

[0012] 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

The invention relates to a bearing rolling body demagnetization machine and a using method thereof. The equipment includes a machine body, a transmission system, an electric control system and a demagnetization system. The demagnetization system is composed of hollow coils and gantry coils arranged in front and rear. The body is equipped with a universal steering controller and a conveyor belt frequency converter. The universal steering controller is used to adjust the power of the demagnetization coil, and the frequency converter is used to adjust the conveyor belt. speed. There is an adjustable hoof angle at the bottom of the body. The upper part of the conveyor belt is equipped with a conveyor belt fine-tuning device and a tensioning device. The method of use is: the conveyor belt rotates circularly under the drive of the transmission motor, transmission chain, and transmission shaft. The number of revolutions is adjusted by the frequency converter, and the power of the demagnetization coil is selected and determined by the universal steering controller. The demagnetized workpiece passes through at a uniform speed under the drive of the conveyor belt. Fully enclosed hollow demagnetization coil and fully enclosed gantry demagnetization coil complete the demagnetization process, easy to operate and good demagnetization effect. It can meet the demagnetization needs of workpieces of different specifications and 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...
