Description

Technical Field

[0001] The utility model relates to the technical field of iron core cutting, in particular to an iron core cutting device with stable clamping. Background Art

[0002] The current transformer is an instrument that converts the large current on the primary side into the small current on the secondary side for measurement based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and a winding. The iron core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and coated with insulating paint on the surface. The iron core and the coil wound on it form a complete electromagnetic induction system. The power transmission of the power transformer depends on the material and cross-sectional area of ​​the iron core. Therefore, a cutting device is required in the process of processing the transformer core, which can also facilitate the user's subsequent use of the transformer core.

[0003] Most of the existing core cutting equipment directly uses positioning blocks to clamp and fix the core during cutting. For example, China Patent Authorization Announcement No.: CN 212070579 U discloses a transformer core cutting device, which uses a threaded rod to drive the positioning clamp to move and clamp the core. However, the positioning clamp of the above clamping structure is prone to loosening due to vibration during use, resulting in unstable clamping of the core, thereby reducing the core cutting accuracy and making it difficult to collect the debris generated during cutting.
