Description

Technical Field

[0001] The utility model belongs to the technical field of transformer production, and in particular relates to a transformer core polishing device. Background Art

[0002] The transformer core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with high silicon content and coated with insulating paint.

[0003] If there are burrs on the side of the transformer core, the flatness and uniformity of the core will be destroyed, causing the core to vibrate or make noise during the operation of the transformer due to these tiny protrusions. Long-term vibration will not only affect the normal operation of the transformer, but may also cause local deformation or damage to the core, thus affecting the service life and performance of the transformer. For this reason, the transformer core needs to be polished.

[0004] Since the transformer core has inclined sides, such as Figure 1 As shown in the figure, when polishing different positions on the side of the transformer core, the worker needs to adjust the processing posture to adapt to the bevels of different angles of the transformer so that each position can be polished effectively. Frequent adjustments not only increase the complexity of the operation, but may also reduce work efficiency and polishing quality. Maintaining different processing postures for a long time may also cause fatigue or discomfort to the worker's body. Utility Model Content
