Description

technical field

[0001] The invention belongs to the technical field of bearing manufacturing, and in particular relates to an online demagnetization circuit for fast response bearing rings. Background technique

[0002] Fully automatic bearing production lines have been widely used in the bearing manufacturing industry, and many of the grinding equipment on the bearing production line use electromagnetic coreless fixtures as tooling to support the bearing rings, and the bearing rings are adsorbed on the magnetic poles for grinding . After the grinding process is completed, some residual magnetism remains on the bearing ring, and the unloading mechanical device will move the bearing ring into the discharge channel, and the bearing ring will roll down along the inclined discharge channel, and enter the Go to the demagnetization device for demagnetization. After the bearing ring is demagnetized, it will automatically leave the demagnetization device and enter the next processi...
